Renaissance Philanthropy | Research Engineer (Speech AI/ML) | Remote (worldwide)
Renaissance Philanthropy's aim is to activate a virtuous circle of increasing ambition and impact between philanthropists and innovators: by identifying frontier experts both in science and in new ways of solving problems; by tapping into the growing number of emerging philanthropists; and by building multi-sector initiatives that can harness the power of philanthropy, markets, and governments.
RenPhil's Engineering Hub supports mission-driven, grant-funded educational technology projects that seek to improve educational outcomes in fundamental skills like math and reading. This summer we're launching a program called LEVI Literacy, which has a goal of halving the number of struggling readers in the US within 5 years.
We're looking for an expert in modern voice AI to support this work. Our partner teams are building tools that assess and support early reading directly from children's speech in real classrooms — oral reading, spoken vocabulary tasks, whole-class instruction. These are hard, meaningful speech problems: young children's voices, noisy multi-speaker environments, and high stakes for getting it right — and fair — for every student.
We're looking for folks who:
- have built and operated production ASR or speech-processing systems
- know the full data-to-model pipeline: collection, annotation, fine-tuning, evaluation, and deployment
- can speak the languages of both research and engineering
- want to help create a world where all children learn to read well.
If this sounds like you, please apply!

G-Research | https://www.gresearch.com | London UK, on-site | Full-time
G-Research is a leading quant finance company. Big compute farm, interesting problems.
My team is hiring senior engineers to work on our (actually world class) DAG scheduling infra for distributing research and production workloads across the compute farm. What we do is roughly:
* maintain and improve the SDKs for that scheduler in Python, F#, and C#
* add interesting new features to the scheduler itself
* maintain and improve a web backend and UI for quants and engineers to monitor their jobs, increasingly with high availability requirements
* translate bidirectionally at the business level between low-level infra providers and quant/ML researchers
Some functional experience preferred, because our core product is in F#. Lots of dealing with very smart researchers and engineers, with the kind of fun problems arising when you run large ML workloads at scale.

Aeolus | DevOps Engineer | San Francisco, CA (onsite) | Full-Time Aeolus is seeking an exceptional DevOps Engineer to take ownership of the cloud infrastructure and deployment systems that power our mission in applied atmospheric science.
In this role, you'll be the technical foundation our scientists, ML engineers, and software engineers build on. At the core of our efforts is an operational physical weather model written in Julia, executed on GPUs. Responsibilities include designing and operating cloud environments, deployment pipeliness and infrastructure-as-code that keep our systems reliable, scalable, and fast. Our ideal candidate has extensive experience in HPC environments with Slurm management.
Deya | Multiple Roles | New York, NY | HYBRID (NYC) or REMOTE | Full-time | https://deya.health/careers/
Everyone in health AI is chasing scribes and diagnostics. Almost no one is building the longitudinal data layer that captures what actually happens to patients over time. That is the real moat, and we are building it for eye care.
Deya sits between doctor and patient, capturing symptoms, treatments, outcomes and ocular images over time. Clinician-led, piloting with eye doctors, and we hold the largest dataset of eye images captured on smartphones. We build with AI tools daily.
Three roles, all high ownership:
Software Engineer (AI x Healthcare) - Product and infra from 0 to 1. Next.js, backend, cloud, agentic workflows, longitudinal clinical data.
Mobile Engineer (React Native, Swift, Kotlin) - A modern phone is already a clinical instrument and almost none of it has been pointed at eye care. Own the app and its UX end to end.
AI Engineer (Computer Vision + LLMs) - Own the vision pipeline turning phone photos into clinical signal, plus the LLM systems reasoning over patient history.
We have a proprietary clinical dataset and because we control capture, you can improve the data itself rather than model around its limits. Optometrists and ophthalmologists in-house to define ground truth and validate the work. Competitive salary plus equity.
All three roles and apply: https://deya.health/careers/
EggAI | Tech leads (Platform and Software) and Platform engineers | REMOTE (EU) | Full-time preferred. Contract possible.
We are a small boutique consultancy and are quite experienced. A lot of us have extensive consultant experience. You will join a small, highly skilled remote team of engineers and transformation practitioners working at the forefront of enterprise AI.
We use AI for both development and in our solutions. We are looking for engineers that are critical thinkers, understand the limitations of AI but also where it can have a positive impact.

Vitalize | Senior Product Manager or Staff Product Manager | San Francisco (hybrid)
What we do: Hospitals run critical operations (staffing, labor planning, and capacity) on spreadsheets, phone calls, and gut instinct. Labor is the biggest cost and hardest operational problem, and it’s still largely manual. Vitalize is building the operating system for hospital labor (and ultimately capacity): we forecast demand from real hospital data (e.g., ADT + historical patterns + acuity) and translate that into concrete staffing decisions: next month’s schedule and the next shift.
Traction: - ~$37M raised - Launched 2024; ~$13M committed ARR across 10+ health systems - Live in 20+ hospitals and growing quickly
The role: We're hiring a PM to own the product experience that takes a hospital from signed contract to successfully using Vitalize in production. Getting there is complex: every health system has its own HRIS, scheduling workflows, union rules, and technical environment. This team builds the custom integrations and internal tooling that make those deployments faster, more repeatable, and less manual as we scale.
We're looking for a PM who... - Led messy third-party enterprise integrations deep enough to make real technical calls with eng - Has built internal tooling with an internal team as the customer - Prioritized a roadmap under live GTM pressure and held the line when the loudest deal wasn't the right build - Startup experience, where the system you were building didn't exist yet
If you're interested, email me [email protected]
Comp: $215K-$260K + equity
Mingla | CTO (ONSITE, Stockholm) or Part-time Engineer (REMOTE ok) | https://mingla.com
Mingla makes strangers meet at in-person events: attendees scan a QR code and are straight in — no App Store, no signup — gamified missions start real conversations, and the organizer gets proof of what happened in the room.
You'd own the platform end to end: Elixir/Phoenix backend (Ash, GraphQL, Postgres) and a native SwiftUI iOS app — the QR entry is an App Clip. We're open to two setups: a full-time CTO onsite in Stockholm, or a part-time engineer who can work remote.
Apply: [email protected], subject "HN: CTO / Engineer", with a link to something you've built and one line on which setup fits you. No cover letter needed.
ORIGAMICS | Founding Researcher | San Francisco | ONSITE/REMOTE
Origamics is building AI models that reason about electronics and help turn schematics into production-ready boards.
We’re looking for a Founding Researcher to work directly with the founders on physics-informed models for Electronics design — physical behavior, simulation, and scientific ML. You’ll tackle open-ended research problems, push models from experiments to production and real hardware, and have the opportunity to publish novel research along the way.
You’ll likely be a good fit if you have strong ML/research fundamentals, enjoy 0→1 problems, and have experience with scientific ML, geometric deep learning, numerical methods, simulation, EE, or applied physics. PhD is a plus, not a requirement.
Apply: https://www.origamics.ai/join-us?ashby_jid=7acf3a2d-46a5-420... (Mention HN when applying.)

Axo | Lead Founding Engineer | Sugar Land / Houston, TX (HYBRID) | Full-time | $120k–$160k + Founding Equity
Want to help out healthcare providers? Clinicians using our software are already saving hours a day and loving their job again. We are building Axo to make the software layer as invisible and ambient as possible, letting clinicians direct 100% of their attention to patients rather than screens.
Our first market is orthotics and prosthetics (O&P), the field designing braces and artificial limbs that restore human mobility and underserved by the tech sector. You’ll join as a founding engineer working directly with myself (former Google SWE) and my co-founder (one of the US's best known O&P clinicians), and small engineering team we want to grow.
You will own massive surfaces end-to-end, making foundational architectural decisions for our entire platform. We've got a massive pipeline ahead and need your help to build it. And we participate in humanitarian missions to expand prosthetic access in critical parts of the world like Ukraine and Sri Lanka.
- The Stack: C#/.NET, gRPC, SolidJS/TypeScript, and PostgreSQL, built with strict domain-driven design and rigorous testing.
- How we work: Flexibility! Love AI-assisted speed coding? Go for it. Prefer to write by hand because your mental model is faster than prompting? Perfect. We only care about delivering safely and quickly.
- Requirements: Senior-level depth with production systems, a strong habit of domain modeling, and a philosophy that defaults to simplicity. Strong UI/UX experience with an obsession for user simplicity is a must.
To apply, email me directly at [email protected] with a short story about a favorite technical challenge you solved end-to-end. Please put "HN" in the subject line! MUST be in Texas.

This is a high-impact, high-visibility role where your decisions will directly influence how we protect our customers, vendors, and employees.
You'll partner closely with cross-functional teams to embed security into everything we build and ship, champion solutions to emerging security challenges, and ensure we stay ahead of an evolving threat landscape. You're someone who embraces AI tools to work smarter — whether that's accelerating threat detection, streamlining vulnerability analysis, or improving how we respond to incidents.

Brilliant.org | Senior/Staff Software Engineer (Interactives) | Remote (North America), SF, NYC | Full-time | $180k-$250k | https://brilliant.org
Brilliant is building the world's first graphical AI tutor: a collection of interactive learning experiences that both the learner and their AI tutor can see and manipulate. In a world of cognitive offloading, Brilliant's AI gets people to actually think and solve hard problems.
We're hiring an interactive-focused engineer to craft the building blocks that power it. Each interactive exposes an API used by learning designers, our authoring agents, and the tutor itself. And every configuration those APIs can produce has to be a correct, solvable, meaningful puzzle. It's a tricky technical problem with a big payoff for our learners.
Engineers at Brilliant think about both "building the right thing" AND "building the thing right" while pursuing high standards of excellence for ourselves, our product, and our codebase.
If you're energized by the prospect of doing the best work of your career and changing how the world learns, you can learn more and apply here: https://brilliant.org/careers.

Discord | Senior Software Engineer, Application Security | San Francisco, CA | ONSITE | $280K–$330K TC
Discord is where communities and friend groups spend time together, on desktop, mobile, and now more and more inside games and third-party apps built on our platform. That surface area, plus a huge, engaged, occasionally adversarial user base, makes application security a genuinely hard and interesting problem here.
We're hiring a Senior Application Security Engineer to join the Product Security team. Responsibilities include threat modeling and secure design review with product and platform teams, building and improving AppSec tooling (SAST/DAST/dependency scanning), and working directly with engineering teams to remediate findings.
Stack: Python primarily, some TypeScript/React, some Rust, occasional JavaScript. Runs on GCP.
Looking for: hands-on AppSec experience (not just compliance-flavored security), comfort reading and reviewing code across languages, and sound judgment on prioritizing real risk over checklist security.
Interview process: recruiter call, coding round, HM interview, virtual onsite, decision.
Apply: https://job-boards.greenhouse.io/discord/jobs/8656854002
InfoHawk | Software Engineer | London, UK or NYC | REMOTE (UK or US), occasional onsite | Full-time | https://www.infohawk.com
Fraud reaches people through ads, cloned brand sites, counterfeit shops and AI-generated video, and it moves faster than any manual review. InfoHawk detects it while it is still running, correlates it across platforms and formats, and surfaces it early enough for our customers to act. We are a small team of engineers plus security, privacy and fraud specialists. Pre-seed, $2.25M led by Moonshots Capital: https://www.infohawk.com/news/2026-06-08-pre-seed-funding-an...
You’d own how data gets in: scrapers and collectors that survive source changes, official APIs where they exist, undocumented endpoints where they don’t. Sources break constantly. Can you figure out how to use AI to spot the change and adapt automatically? Stack: TypeScript, Node, SvelteKit, Postgres, Playwright, heavy AI-assisted development.
We’re looking for ~3-5 years building scraping or integration systems in production, but if you’re a great engineer who doesn’t tick every box we’d still like to hear from you. UK-based for London, US-based for NYC; we cannot sponsor visas. Two of our three founders are engineers, one in each city, and you’ll work with them directly.

Noricum | Senior Backend Engineer, Payments, Ledger & Provable Fairness | REMOTE (2h overlap with US Pacific) | Contract to permanent | $120-160/hr | Start by 14 Sep
I'm the founder of Noricum where we build platforms – currently the money infrastructure, ledger, engine and payment rails behind a pre-launch wagering platform with a Steam skins economy. The games, a cashier and a bet ledger are built and live as a front end, with written specs for the server contract: ledger schema, refusal table, round lifecycle, every game's arithmetic. Processing and licensing are secured. The server does not exist. That is the job. You would own:
- A server-authoritative game engine - seeds, nonces, outcome computation - A double-entry ledger where balance is derived and no client write can change it - Server-side enforcement of every limit and refusal - Payment rails idempotent under duplicated webhooks - Seed custody and the provably-fair lifecycle - An affiliate system with referral attribution and commission payouts
Must have shipped: a double-entry ledger or equivalent money system in production, a payment integration including webhook idempotency, auth and sessions you built and operated, and infrastructure you owned end to end. Provably-fair systems, settlement-side gaming or trading infra, or Steam trade automation all stand out.
Email [email protected] with your start date and a few lines on the last money system you shipped - what it guaranteed, and how you knew it held.

ODK | Senior Product Manager | Remote (Worldwide) | Long-term contract, 30–40 hours/week | $90–$110/hour USD
ODK is an open-source platform used by thousands of organizations worldwide to collect billions of data points for disease surveillance, supply chain traceability, environmental monitoring, and more. It enables users to build powerful forms and reliably collect structured data, even in places with little or no Internet connectivity.
ODK has been actively developed for 18 years. We have a mix of self-hosted and SaaS users across many sectors. We're looking for a senior product manager who will own product discovery and prioritization across this diverse user base. To be successful, you'll need to find the common needs behind very different workflows and turn them into opinionated product improvements.
Because the team is small and the user base is large, this is a high-autonomy role where product decisions have an unusually direct impact. You should have substantial experience managing complex B2B or technical products. Experience with open source, self-hosted software, and small, fully remote teams is a plus.
