AI SWE Intern Summer 2026

Fresco AI is building the next-gen AI assistant for the $12T construction industry. Backed by Y Combinator, SignalFire, and Bessemer Venture Partners, we work with top national and Bay Area general contractors to help field teams instantly find and act on info buried in project documents and drawings. We’re looking for an Engineering Intern to join us in San Francisco. You’ll ship real features, touch production on day one, and solve domain-specific problems that don’t have off-the-shelf answers. What You’ll Do

• Ship end-to-end features across web and mobile (Next.js/React/TypeScript + Expo).
• Improve retrieval quality in our AI stack (embeddings, pgvector, hybrid semantic + lexical search, OCR/vision on plans).
• Talk to users (supers, PMs) and close the loop the same day—measure, fix, ship.
• Help shape data models and APIs that keep everything fast and reliable.
• Pair with the CTO on product bets and longer-term technical direction.

Our Stack

• Frontend: React + TypeScript
• Backend: Next.js + TypeScript
• Some Python for deep computation
• Mobile: Expo (React Native)
• Data/Infra: Postgres + pgvector (Neon), Prisma, Vercel, S3, AWS Textract
• AI: OpenAI (GPT-4.x/vision/embeddings), RAG over docs/drawings
• Process: PRs for visibility, lightweight review, high ownership. We believe great data models make the rest of the code flow.

You Might Be a Fit If

• You’ve built and shipped something meaningful (apps, tools, research—show us).
• Comfortable with React/TypeScript, Node, SQL—or eager to ramp fast.
• Curious about construction and how software lands in the field.
• Low-ego, high-ownership, biased to ship and iterate in tight loops.
• Able to join us in person in SF for a full-time internship (10–12+ weeks preferred).

Why Fresco

• Work directly with leadership—our CEO and CTO sit a desk over.
• Your code will be used by leading general contractors, not just in a demo.
• Backing from top VCs (YC, SignalFire, Bessemer) and a fast path from idea → production.
• Small team, immediate impact, zero bureaucracy.

Schedule: In-person, SF. Typical hours ~9am–7pm, Mon–Fri. (Optional Sunday hack time if you’re itching to build.)\ Note: This is a full-time, in-person internship .
