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.

RINSE | REMOTE or San Francisco, Los Angeles, Chicago, Boston, New York, New Jersey, Seattle, Austin, Toronto, or Washington DC | Software Engineer | Full-Time | Salary: $80k-$200k USD | https://www.rinse.com

Rinse provides dry cleaning and laundry delivery services to customers in twelve metropolitan areas in the US and Canada. We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.

Our engineering team is distributed across the United States and internationally, and has been entirely remote for years now, but a desk can be provided in the above cities if you'd prefer.

We're open to both newly-graduated engineers or more senior engineers, provided they meet our bar. We're particularly interested in true full-stack engineers, with strong React / Typescript / CSS skills to complement comfort in a Python / Django environment. We're also seeking engineers with experience leveraging AI to automate complex operational processes.

We're particularly interested in someone with significant React Native expertise at the moment, as we work to improve the apps our customers, delivery valets, and partners use.

You will join a high-caliber team where collaboration, honesty, and open communication are at the core of everything we do.

Search term bingo: Logistics, Django, Python, Optimization, React, React Native, Postgres, Mobile Engineer, Automation, Delivery, OR-tools, Forecasting

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, FGPA, 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!)

We’re a start-up company, we are building a local-AI camera OS that replaces cloud CCTV: SigmaStar cameras → RTSP/ONVIF → HDMI node → on-device AI (offline-first).

1. Hiring: OS / Device Lifecycle Engineer (Secure Boot / OTA / Identity) (Remote, UK/EU preferred)

We already run RTSP + inference. Now we need the person who owns several year device reality.

You will own (single layer ownership): Secure boot / trust chain (ROM → U-Boot → kernel → rootfs) OTA updates + rollback strategy (A/B, recovery modes) Device identity & lifecycle (provisioning, key rotation) Failure recovery (power loss, corrupted SD, watchdogs)

You must be able to answer directly: SD vs eMMC vs NVMe tradeoffs + corruption mitigation Brown-out behavior, thermal throttling, BSP maturity Camera ISP/NPU concurrency constraints + vendor SDK realities

2. Hiring: Independent Embedded/Firmware Engineer (Bring-up Audit & Stability) (Remote UK/EU preferred)

We’re shipping on real hardware. Reliability beats elegance. We need a senior embedded engineer to audit and validate our assumptions and prevent single-point-of-failure risk.

You will own: Independent review of firmware/bring-up assumptions Validation of performance, thermals, power behavior, stability Reproducible test plans (what breaks, how to detect, how to recover) Documentation that prevents knowledge living in one head

If you’ve shipped embedded systems that survive ugly reality (packet loss, unplugging, thermal throttling, storage corruption), we want to talk.

Competitive salary, flexible working environment & location, if you are interested, feel free to email: [email protected] (subject: “HN – Role”)

Silkline | Senior Software Engineer | Seattle | ONSITE (5 days/week) | $175k-$225k + equity | https://silkline.ai

Our customers: Machina Labs, Astranis, K2 Space, Castelion, Antares, and more. They use us to manage suppliers, track $M+ in orders, automate RFQs, and stay ITAR-compliant. Every day of production delay costs $50k+—our platform keeps them moving.

The role: Own features end-to-end, build ERP integrations that sync POs and manufacturing data, real-time order tracking dashboards, and a user experience that people LOVE. Work directly with customers whose supply chains depend on what you ship.

Stack: TypeScript, React, Next.js, Hasura (GraphQL), PostgreSQL, Trigger.dev, AWS GovCloud, Pulumi, Elbow grease.

You: 5+ years shipping production systems, strong full-stack or frontend generalist who moves fast, thrive on customer feedback and direct impact, bonus: ERP integrations, B2B SaaS, or regulated industries

Traction: 5x'd customer count last year, $5M funding to date, landing massive defense/space logos. Small team shipping incredibly fast—you'll work directly with our founders (Isaac and myself).

Deep Systems | Senior DevOps Engineer | Remote EMEA, APAC, and Americas | Full-time

I am building a DevOps team at a capital markets tech company most people haven't heard of — but some of the world's biggest financial institutions run on our platform. 300B+ messages/day. 99.99% uptime. Mostly on-prem, Linux, purpose-built hardware.

You'd be working on systems support, tooling, and helping build a custom observability platform in Python — because off-the-shelf monitoring doesn't cut it at this scale.

Capital markets / FIX experience is a plus, not a requirement. Appetite for learning is.

The vibe: small global team (US/APAC/EMEA), fully async, deeply technical. Leadership still codes. No hand-holding, no fluff.

Mainly focused on US and EMEA hires (we currently have people clustered in Belfast and North Macedonia); for APAC, we have solid leads. We don't have salary expectations to publish. We are open to different engagements given regional and your personal factors, including contract, W-2, contract-to-hire, etc.

Senior IC role, report to me directly.

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.
