Krea | Distributed Systems & Backend Engineers | San Francisco, CA (onsite+remote)

I'm the cofounder & CTO of Krea (https://www.krea.ai). We are a startup in San Francisco building browser-based AI creative tools for professional designers and creatives. Small team (~27); millions of active users; and raised +$80M from top SV investment 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. You will...

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

- Learn ML engineering from world-class researchers on a small tight-knit team. You’ll contribute to foundation image, video, and world models from 0 → production, and see them used by millions.

- Play with huge Kubernetes GPU clusters; our main GPU cluster takes up an entire datacenter from our provider.

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 experience with dist. systems, k8s, and existing ML or data experience (but not required!). Cool side projects are a green flag.

Tandem Health | Software Engineers | On-site in Stockholm, Sweden | Full time

At Tandem Health we're building a clinician copilot to allow clinicians to focus on care rather than administration. We’re building, launching and iterating quickly, and are already rolling out across some of the largest care chains across Europe, including most of the NHS.

Our core product listens in to the patient-clinician encounter to generate medical records, allowing clinicians to save 5-10 minutes per patient. No longer do clinicians have to catch up on administration after hours. Some even tell us that their partners notice they're much more relaxed after starting to use our product, and we couldn't be happier :)

We’re expanding our Stockholm team with exceptional engineers! We use Python (backend), TypeScript/React (frontend) and C# (Windows app) and our infrastructure runs on Kubernetes in Azure.

Even if we don’t have a role out your specific skill set, we’d love to talk! Our tech team is small but growing and you’ll have an outsized impact on an important problem.

Feel free to reach out to john.moberg@tandemhealth.ai if you have any questions!

* Talk to existing customers, capture use cases, keep relationships warm * Create simple content (short screen-recorded videos, posts, case snippets) * Find look-alike companies/institutions and do human, non-spammy outreach * Coordinate with relevant creators (YouTube/bloggers) for deep-dives * Occasionally post in relevant communities (Reddit/Discord/forums) transparently and helpfully No coding required, but you should be comfortable with technical users and Windows tooling. I’m optimizing for someone autonomous who can run with outreach + content.

Comp: contract, €60–€120/hour depending on fit, 8–16h/week. Start with a small paid test project. Bonus possible for meaningful outcomes (pilots/case studies/revenue growth).

Email: info@mousemux.com with (1) short intro, (2) 1–2 examples of content/outreach, (3) why MouseMux.
