Founding Engineer Intern
Clera
A fast-growing, pre‑seed AI startup in the talent and recruiting space is looking for a Founding Engineer Intern to join their founding team in San Francisco. You'll work directly with the CTO to ship features daily and help build a fully agentic system that automates headhunting end‑to‑end. This role puts you at the center of rapid experimentation with real ownership and high‑impact outcomes — including time in hacker‑house environments in Latin America. What You'll Do Build and ship features daily alongside the CTO to automate the recruiting process end‑to‑end. Own full end‑to‑end development — from ideation to production — for core product features. Collaborate with the founding team to design and ship components of an agentic AI system. Talk to users and measure impact on hiring speed to drive rapid iteration. Thrive in a founder‑paced, high‑output environment with daily feedback loops. What We're Looking For Required At least 6 months of experience with React and TypeScript in a production environment. Hands‑on experience with Cursor, Supabase, Prisma, and Typesense in a production React/TypeScript stack. Full‑stack focus — not an ML engineer and not overly specialized in a single language (e.g. Python or C++). Strong ownership mindset with the ability to drive features from ideation to production independently. Currently enrolled in or pursuing a degree in Computer Science, Software Engineering, or a related field. Something outstanding about your profile — top GPA, strong university, impressive projects, or an active GitHub. Experience working in entrepreneurial, fast‑paced, scrappy environments. Willingness to work 7 days/week and participate in hacker‑house setups in LatAm. Nice to Have Portfolio or sample projects demonstrating full‑stack development and open‑source contributions. Location Based in San Francisco, CA . On‑site role with hacker‑house periods in Latin America. Visa sponsorship is available. #J-18808-Ljbffr Clera
