Property Meld | Mid-level and Senior Software Engineers, Product Designer, Product Manager | Full-time | Remote (US & Canada) or Rapid City, SD

Looking for something more meaningful? How about the opportunity to have a direct impact on the property maintenance experience for hundreds of thousands of residents?

Welcome to the future of property maintenance. Property Meld’s vision is to radically improve how the property management industry handles property maintenance. If you’ve ever had a maintenance issue at your housing rental, you know how much of a pain it can be to get it fixed quickly and reliably. It doesn't have to be this way. We're rethinking the entire property maintenance experience from the ground up with two things in mind - first, driving the cost of doing maintenance to the absolute minimum, and second, providing an experience to residents and property owners that makes them want to stay with their property manager. If you are excited about turning something that has historically been a negative experience (maintenance) into a positive experience, we'd love to talk with you.

krea.ai | Distributed Systems Eng. & Data Engineers | San Francisco (on-site), CA

I'm the cofounder of Krea (https://www.krea.ai), a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and creatives. Small team (~15); millions of active users; and we've raised over $83M from top silicon valley firms.

We're looking for talented engineers who want to tackle hard technical challenges with smart people while building a creative platform that big companies and startups will rely on.

The job:

- Build distributed systems to process massive (billions of files, petabytes), amounts of image, video, and 3D data, solving scaling bottlenecks as you go.

- Work with our research team to build ML pipelines and deploy models to make sense of raw data (example - find clean scenes within videos).

- Learn ML engineering from world-class researchers on a small tight-knit team. As you’re building data pipelines, you’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions of Krea users.

- Play with massive amounts of compute on huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.

Our tech stack: python, pytorch, k8s, a rotating cast of data tools (e.g. DuckDB, massive relational dbs, PyArrow, etc.)

You should apply if you are an excellent generalist engineer with strong backend experience and an intuition for systems design. Bonus points for deep experience with distributed systems, kubernetes, and existing ML or data experience (though not required!). Cool side projects are a green flag.

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
