Full-Stack Engineer

We build an ads engine that learns as it goes: brand book, taste, and what actually performs in every market. It plans, generates, localizes, launches and learns from ads across the major ad platforms, using ElevenLabs’ full audio and video stack.
You’ll be a founding engineer for a product area of your own. There’s no PM and no handed-down spec. You’ll talk to users, decide what to build, and ship it across the stack, from data pipelines and agent tools to the UI. Early work could include feeding competitive intelligence into the engine’s weekly briefs or launching a new ad format.
We’re looking for founders and founding engineers. You’d rather ship a rough v0 on Friday than a perfect design doc. Strong engineering is the minimum. What sets people apart is product judgment and ownership.

Requirements

• 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.

Bonus: experience with ad platforms, adtech or marketing tools; analytics and attribution; web builders and CMSs; taste in creative.
