At IP Fabric, we’re redefining how enterprises see their networks. Our platform uncovers the truth hidden inside complex infrastructures — automatically discovering and modeling massive network graphs in real time.

We’re now looking for a Senior Backend Developer to help us shape the future of our Network Automation Engine — the brain behind our Discovery Service.

You’ll build a distributed service responsible for scanning large-scale computer networks (hundreds of thousands of devices), collecting configuration and topology data, and building an accurate network graph. The service is being redesigned for parallel exploration to significantly improve performance, scalability, and data freshness, while ensuring correctness and avoiding duplicate discovery paths

We’re heavy on Node.js/TypeScript, exploring Go, and thrive on clean, scalable, and resilient design.

If you love distributed systems, own your code end-to-end, and want to join a team of engineers who build the tools they once wished they had — we’d love to talk.

Pareto.AI | Multiple Roles | INTL REMOTE, US REMOTE OR HYBRID (SF) | https://pareto.ai

Pareto.AI is in the premium data annotation space, focused on ethical, high-quality data annotation. We work almost all of the frontier labs. We are a fully distributed, remote-first company with engineering teams spread around the world. Some of us work hybrid from our office in SF. There is essentially no restriction on where you're located as long as you're not from a sanctioned country and are willing to adjust to either a US or EMEA timezone.

We have a few full-time, fully-remote roles available. For those two below, we've recently restructured how we do engineering at Pareto and are looking to be very talent dense. I've hired successfully from HN multiple times in the past, so if you have expertise in those respective tech stacks I'd love to chat:

* Lead/Senior+ Backend Eng: https://jobs.ashbyhq.com/pareto-ai/569f4da0-801c-433a-978f-5...

* Lead/Senior+ Frontend Eng: https://jobs.ashbyhq.com/pareto-ai/47552c42-82c1-4bcd-a1f7-e...

We're also looking to hire some shorter term contractors. We have a couple of projects around refactoring and migrating to a new design system, as well as some shorter term projects around compliance, so if you're only available for a short time we'd likely have room for you too:

* Short term/Contract -> Mid-Staff level Front/Backend/Full stack Eng: https://pareto.ai/careers?ashby_jid=4cbdb231-c7c5-40cd-ad9d-... this

Backend code-writing roles require a really strong command of Python. Equally for the frontend roles you really need to understand your TypeScript and React. You're expected to have a lot of responsibility.

No recruiting agencies or similar.

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

I'm the cofounder & CTO of Krea (https://www.krea.ai). We are a startup in San Francisco building browser-based AI creative tools to improve the workflows of artists, designers, and professional creatives. Small team (~24); millions of active users; and raised over $83M from top Silicon Valley 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.

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.

- 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.
