Ask HN: Who is hiring? (March 2026)

Softmax | softmax.com | San Francisco (onsite) | Full-time

THE MOST IMPORTANT UNSOLVED PROBLEM IN AI IS THE MOST POWERFUL OF ALL CAPABILITIES: ALIGNMENT.

Hi, I'm Emmett. You may know me as the founder of Twitch (YC S05), and as the (extremely) interim CEO of OpenAI.

I believe the question of how AI systems learn to understand themselves and others is one of the most consequential technical problems of our time. If we get it right, the agents we build today will become our friends and collaborators tomorrow. And the infrastructure required to train agents that are good at working in teams and societies will be extraordinarily valuable.

Softmax is building large-scale multi-agent, multi-policy environments that will benchmark AI agents – both our own and others – on their capacity for theory of mind, adaptive goal setting, and teamwork. We’re looking for the engineers who will make that possible.

The work is unusually hard. The problems are ambiguous and challenging. High autonomy, high expectations. You'll work directly with me and the rest of our small but mighty team.

If this sounds exciting, I’m looking forward to meeting you. E

Osaurus | Full-Time | Remote | Protocol Engineer

Osaurus is a native macOS AI platform. The core idea: inference is a commodity — everything else (context, memory, tools) should be owned by you, locally. Think of it as the runtime layer for AI on Mac that works with any provider (OpenAI, Anthropic, xAI, local models via MLX).

3.7K+ GitHub stars and 54K+ downloads with zero marketing spend. Open source, local-first, provider-agnostic.

Looking for a protocol engineer who wants to build agent-to-agent networking and communication infrastructure. You'd be the first hire.

What we work with: Swift, macOS native APIs, Apple Silicon optimization, provider-agnostic API layer, plugin architecture. You don't need Swift experience specifically — strong systems fundamentals and the ability to pick things up fast matter more.

If this sounds interesting, try the app (https://github.com/osaurus-ai/osaurus), share your GitHub, and tell me what you'd change.

SkySafe (https://skysafe.io) | Wireless Engineer (SDR) | San Diego, CA | ONSITE (Hybrid)

At SkySafe we build drone detection and tracking at scale.

I am looking for a Wireless Communications Engineer with SDR expertise to join my team - I'm the hiring manager.

I need someone with a very strong background in signal theory and experience building software wireless modems. You will spend time learning about new systems from our reverse engineers (no RE experience required!), implementing both open and recovered specifications, and refactoring existing modems code to improve it in both theory (ie - what is the algorithmic state of the art for demodulating xyz thing) and practice (ie - how much memory bandwidth and CPU are you using where). As such, I'm looking for someone with true software modem experience; while DSP, FPGA, and generated code experience are useful and relevant, you'll need to be able to read and write C++ directly.

I need someone who can come into the office in San Diego as needed to work with hardware, so this is a hybrid on-site role. This position requires access to technology which is controlled by US Export laws, so you also need to be an eligible US Person.

What we have to offer: $145-200k. Fun, small team dynamic. Work with experts in adjacent fields. Startup environment with good work-life balance and limited red tape. Rapid iteration and feedback in the wild. Good equipment at the office.

Apply: brian@ for a direct line, https://jobs.lever.co/skysafe for the formal route (we have some other roles I'm not the HM for listed there, too, if you're interested in the company!)

Prequel | Software Engineers (backend or full-stack) | NYC (ONSITE) | $170k-$210k | prequel.co

Prequel enables software companies to sync data to their customers' data environments, at massive scale. With the rise of agents, syncing data to customers' data environments is becoming table-stakes for a lot of software companies. We make that incredibly easy for them.

We're a team of four engineers based in NYC. We're cash-flow positive and growing fast. We're solving a number of hard technical problems that come with syncing hundreds of billions of rows of data every day with perfect data integrity: building reliable & scalable infrastructure, making data pipelines manageable without domain expertise, and creating a UX that abstracts out the underlying complexity to let the user share or receive data. We're powering this feature at companies like Stripe (Metronome), Gong, Iterable, and more.

Our stack is primarily Golang/K8s/Postgres/DuckDB/React/Typescript and we support deployments in both our public cloud as well as our customers' clouds. Due to the nature of the product, we work with nearly every data warehouse product and most of the popular RDBMSs.

Lead Full-Stack Engineer Marker Learning | Remote (U.S. only) | Full-time | Engineering | 185-250k

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled.

Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.

Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.

This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.

We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.

Reach out directly with your resume and why you want this position to [email protected]. Make the subject "Lead Engineer Application (I am not a bot)".

OmniAI (YC W24) | https://getomni.ai | Full Stack Engineers | SF In-Person | Full Time | $125k–$200k • 0.50%–1.50%

Tech stack: TypeScript | Node | React/Next.js | Postgres | Docker | K8s | LLMs

We’re building the AI-powered infrastructure layer for small-business lending. Banks and fintechs use Omni to automate document collection, financial modeling, public-record research, and ongoing borrower communication.

You’ll work on:

1. Wrangling messy PDFs into usable data (we built a major open-source extraction library: https://github.com/getomni-ai/zerox)

2. Aggregating millions of datapoints from 50+ public sources (UCCs, liens, licenses, tax records) + credit/KYC/AML data

3. Building real-time financial models that combine OCR, LLMs, and rule-based systems into predictable outputs

We’re early, you’ll have a huge impact. Email me (my name at the URL) or apply here: https://www.ycombinator.com/companies/omniai/jobs/Dr0GIaE-fu...

Fractional AI | Senior/Staff Software Engineer | SF, NY, NC, Dubai | Onsite

We’re a team of experienced generalist SWEs and AI enthusiasts who are building custom AI agents for enterprise clients. You’ll work on 3-4 different projects a year and play a central role on each one. No AI experience required: we are actively trying to be the best place in the world to learn applied AI.

I’m Frank, an engineer here. This is the first services-style company I’ve worked at, so for those of you in a similar boat, this is what I’ve really liked so far:

* The learning rate is super fast. 3-4 client projects a year, each with different tech stacks, products, industries, and architectures.

* Our projects are typically high priority and sponsored by prominent executives. The path here for projects to have real impact on usage or bottom line is much shorter.

* We’re “selling pickaxes during the gold rush”. When AI finds its next killer app, we’ll hopefully be the first to know about it.

We’re hiring SWEs onsite with offices in San Francisco, New York, Durham NC, and Dubai. Feel free to reach out to me directly ([email protected]) or take a look at the full job posting:

Starbridge | Senior Engineers (Kotlin/Java/React/Typescript) | NYC or Remote | Full-time | starbridge.ai

Starbridge is building an AI platform that turns large-scale public and enterprise data into reliable sales insights. We are early, moving fast, and building from zero to one, so this role will have huge ownership and product impact.

Product Engineer: (React/Typescript) who would work closely with product and design to build user-facing parts of the platform. You will craft performant, stable frontends that explain technical concepts to non-technical users and help us iterate fast based on customer feedback.

Backend Engineer: (looking for Kotlin/Java/Scala experience). You'll work across the backend: building enterprise integrations, large-scale scraping and parsing pipelines, and systems that let users apply LLMs to millions of documents to generate insights at scale.

AI Engineer: Applied AI plus strong software engineering. You will build, evaluate, and deploy LLM-driven features like deep document analysis and interactive chat, working with models from OpenAI, Anthropic, and Gemini. Expect hands-on Python, ML system design, experimentation, and production reliability. Bonus for RAG depth and frameworks like LangChain, LlamaIndex, or Hugging Face.

We're looking to build our in-person team in NYC but also open to remote!

Apply: https://starbridge.ai/careers and mention HackerNews or email [email protected] with your resume.

PlantingSpace | Full-time | Remote (EU time zone) + Quarterly Meet-ups | https://planting.space

We’re building an AI system for analysts and scientists, based on a fundamentally new approach to reasoning and knowledge representation. Our approach differs from LLMs in that we compose algorithms symbolically to represent complex knowledge, and perform probabilistic computations. This enables the AI-driven application of statistical models to different problems, while providing the user with a verifiable reasoning path, and an assessment of the uncertainty in each answer. We are developing applications for analysis and research in domains such as Finance, Strategy Consulting, Engineering, and more.

This is an opportunity for builders and practitioners to help shape a deep-tech product from its earliest stage.

Spotlight roles:

* Engineering Lead

* Product Software Engineering (Quantitative Modeling)

Ongoing hiring:

* Bayesian Software Engineering

* Program Synthesis Engineering

We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.
