Full-Stack Engineer - Ads Engine

What they're looking for

• Has built and shipped a product end-to-end without anyone handing them a spec, ideally as a founder or one of the first engineers.
• Strong full-stack product engineer (frontend- or backend-leaning is fine) who can build a pipeline, an agent tool and the UI
• Builds with LLMs and agents pragmatically: tools, retrieval and evals, not model research.
• Talks to users without being asked, and can say what they’d build first and why.
