Own meaningful technical work end-to-end — from design through deployment
Build and maintain backend services, APIs, and data pipelines
Collaborate with researchers and ML engineers to ship high-impact features
Contribute to architectural decisions, not just implement them
Write clean, well-tested, well-documented code
Debug and resolve issues across complex distributed systems
Participate in code reviews and help raise the technical bar
What We're Looking For
3–5 years of professional software engineering experience
Strong foundations in your core domain — backend, data, ML tooling, or full-stack
Proficiency in Python and fluency in at least one additional language (TypeScript, Go, Rust, SQL, etc.)
Experience working in production environments with real users
Comfort with ambiguity and ability to operate autonomously
Strong communication skills and collaborative working style
Genuine interest in AI, LLMs, or data-driven systems
Nice to Have
Prior experience at an AI, ML, or data company
Familiarity with LLM training, fine-tuning, or RLHF pipelines
Experience with large-scale data pipelines or annotation platforms
Open-source contributions or published technical writing
Background working alongside AI research teams
What We Offer
Competitive compensation and meaningful equity
Direct impact on how frontier AI models are built
Flexible, remote-friendly environment with low bureaucracy
A small, high-caliber team with deep AI research expertise
Health, wellness, and learning & development benefits
