Attimet (YC F24) Is Hiring Members of Technical Staff – Engineering and Research

Attimet, a YC F24 startup founded in 2024 and based in San Francisco, is hiring a Member of Technical Staff (engineering/backend) to help build what they call the "Prime Radiant" - a research lab and real-time feedback loop that accelerates a small team's ability to form ideas, build systems, run experiments, and learn from reality. Compensation is $125K-$225K with 0.10%-1.00% equity; the role is full-time, on-site in San Francisco, and open to US-citizen/visa-holders. The three-person team includes founders with backgrounds at Optiver, DRW, and Argo AI and plans to apply this platform to financial markets with the long-term aim of managing assets at scale.

The job centers on building LLM-powered systems, agent harnesses, and the surrounding infrastructure - tools for context, memory, evals, orchestration, observability, and execution environments - to turn frontier models into reliable, useful systems. Candidates should be technically sharp, fast learners with hands-on experience building with LLMs, agents, or adjacent AI infrastructure, and show unusually high initiative and product-driven judgment. New grads are considered. Early expectations include owning a meaningful project within two weeks and driving measurable improvements within 30 days. The interview process is rapid and practical: a 10-minute founder chat, a technical deep dive with a practical problem, and a team work session rather than LeetCode-style interviews.
