Attimet (YC F24) is hiring Members of Technical Staff for engineering and research roles in San Francisco. The company is building a research lab with a real-time feedback loop, focusing on AI systems that accelerate how quickly a small team can understand, build, and experiment. The role involves building LLM-powered systems and agent harnesses, designing infrastructure around context, memory, evals, and orchestration, and owning projects end-to-end.

Candidates should have high initiative, technical sharpness, and experience with LLMs, agents, or AI infrastructure. The team values first-principles reasoning and practical results over credentials. The interview process includes a founder conversation, a technical deep dive, and a team work session—no LeetCode-style interviews.

Attimet offers a competitive salary range of $125K–$225K and equity between 0.10%–1.00%. The company's mission is to apply its technology to financial markets and eventually manage the world's assets. The team has over a decade of experience from firms like Optiver, DRW, and Argo AI.

The role provides direct work with founders, real ownership, and the autonomy to drive impactful projects. Attimet emphasizes speed and practical outcomes, making it an ideal environment for those who thrive on solving complex problems and building reliable systems from scratch.
