Surge AI (https://surgehq.ai/careers) | Software Engineers (full-stack / product https://surgeai.notion.site/Product-Engineer-4211688ff99b46d...) and Strategic Project Lead (https://surgeai.notion.site/Strategic-Projects-Lead-Generati...) | Full-time | ONSITE SF or NYC Hybrid

Our mission at Surge is to build the human infrastructure behind the next wave of AI and LLMs. We operate a data platform that powers AI teams at OpenAI, Anthropic, Meta, Google, and more. This year, we've been focusing on RL environments and agentic workflows to help our clients ship agents that interact with the world. Here are some examples of our past work:

- Creating the GSM8K dataset: https://www.surgehq.ai/blog/how-we-built-it-openais-gsm8k-da...

- Collecting RLHF data for Anthropic's Claude: https://www.surgehq.ai/case-studies/anthropic-claude-surgeai...

You’d be joining a rapidly growing team of former engineering and ML leaders from Google, Meta, Twitter, and Airbnb. We work in small groups, ship quickly, and value autonomy and ownership. No previous AI experience is required, if you have the engineering skills you can learn what you need on the job.

We're looking for senior engineers to work out of our offices in SF or NYC, or remotely. Please reach out to us at careers@surgehq.ai with a resume and 2-3 sentences describing your interest. Excited to hear from you!

krea.ai | Distributed Systems Eng. & Data Engineers | San Francisco (on-site), 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 (~22); 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.
