Full-Stack Engineer - Ads Engine

Responsibilities

• ElevenAgents enables businesses to deliver seamless and intelligent customer experiences, with the integrations, testing, monitoring, and reliability necessary to deploy voice and chat agents at scale.
• ElevenAPI gives developers access to our leading AI audio foundational models.
• Everything we do is the result of the creativity and commitment of our team - builders doing the best work of their lives. We are researchers, engineers, and operators. IOI medalists and ex-founders. If you want to work hard and create lasting positive impact, we want to hear from you.
• Learning & development: ElevenLabs proactively supports professional development through an annual discretionary stipend.
• 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.
• 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.
