VersaFeed.com | SENIOR SOFTWARE ENGINEER (Python/Django) | REMOTE (USA/EU) | Full-time

About us: Fancy ETL pipeline which processes products from huge ecommerce companies. Data extraction and massage, delivery to destinations like Google/Meta/TikTok/etc. Profitable, 15+ yrs stable, 100% employee-owned. No VC, no pointless meetings, just serious coding.

Stack: Python/Django, JavaScript, VueJS, PostgreSQL, Snowflake, Docker, Git, AWS, AI/LLM integrations (OpenAI & Gemini).

Compensation: $150K–$250K USD/year DOE.

You: Senior dev who's seen (and fixed) enough dumpster-fire code to last a lifetime. Python/Django deeply internalized; ideally strong Vue (or React) skills. Git/Docker/REST are second nature. You’re the coder other devs come to when their stuff breaks: an architect-level thinker who’s rewritten ‘clever’ code into something that actually works. You play well with others and write code that’s easy to live with. Bonus: AI integrations, Py2→Py3 migrations, Snowflake (or Databricks) experience.

Timezones: VersaFeed's "core" time zone is PST and we have M/W/F standups at 9AM PST. Otherwise, we are async-friendly and welcome US and EU applicants.

Benefits: 401K match (USA), healthcare, equity, fully remote. Stable company with no time-wasters.

Saildrone | Multiple Roles | Onsite/Hybrid (US Only) | SF Bay Area (Alameda) | Full-Time | https://www.saildrone.com/

Saildrone is the world's leading collector of ocean related in situ data via uncrewed vehicle, above and below the sea surface. We work with governments, civic agencies, foundations, universities, and private companies around the globe to derive better information about our oceans and seas - be it sailing drones into the eye of hurricanes to obtain new scientific storm data, mapping out the ocean floor, collecting new CO2 data in hard-to-reach areas, counting biomass to establish fishing quotas, or detecting and stopping illegal fishing and drug trafficking.

Maybe you saw that we've repeatedly hucked drones into category 4 hurricanes[1]. Or maybe that we recently completed a transoceanic cable survey for Meta[2]. And maybe you saw that we just wrapped up a big demonstration for our partners in NATO[3]. Or maybe you didn't see any of that, but you're still intrigued by the idea of autonomous, long endurance sailboats that help us better understand our planet.

Whatever the case, we're hiring for a breadth of different positions across our organization. In software, we're hiring for folks in our Perception, Platform, Frontend, and Vehicle teams. Stacks vary from team to team, but we're looking primarily for folks with backgrounds in C++, Python, and/or JavaScript (Node, TypeScript, React). All software positions are hybrid roles based out of Alameda, just a quick ferry ride across the Bay from San Francisco.

In addition to software engineers, we're also hiring for a bunch of other positions across the company in production/manufacturing, technical operations, and more.

You can see a list of open positions on our career page: https://www.saildrone.com/careers

Please apply through our career page; be sure to select "Other" and specify this HN post when asked how you heard about us!

Breezy | Product Engineer (Fullstack) | Remote (US) | Full-time | $175k–200k + Equity | https://www.getbreezyapp.com

Breezy is modern field service software purpose-built for residential HVAC companies. We combine thoughtful product design, tight customer feedback loops, and best-in-class technology, including LLMs when they’re the right tool for the job, to help contractors grow, streamline operations, and run world-class businesses. We’re already replacing legacy systems like ServiceTitan and Housecall Pro.

We’re a small, senior team with experience scaling successful startups. We ship quickly, stay close to our customers, and take pride in building products that actually move the needle for our customers.

We’re hiring a senior Product Engineer to help define and build the product. This role goes beyond writing code. You’ll weigh in on product strategy, shape user experience, and explore how emerging tools like LLMs can create real customer value. You’ll work across the stack (TypeScript, React, Node.js, PostgreSQL) and own features from idea to production in a high-velocity environment.

We’re looking for someone T-shaped: broad technical range, depth in a few areas, strong product instincts, and a sharp eye for delivering customer value. You should be genuinely excited about AI engineering and not just comfortable with LLMs and modern dev tooling, but actively raising the bar for how your team uses them.

Tech Stack: TypeScript, React, Node.js, PostgreSQL, AWS Comp: $175–200k + equity, full health benefits, 401(k), remote-first with periodic team offsites To apply: Email Email is hidden with your resume, links to your work (GitHub, LinkedIn, personal site, etc.), and a short note on why this role and Breezy are a fit for you
