Full-Stack Engineer (Backend Leaning) - Creative Agents

Overview

Build the next generation of Creative Agents at ElevenLabs as a backend-leaning full-stack engineer. Shape the agent's capabilities and architecture across backend systems, agent infrastructure and the customer-facing experience, combining greenfield development with improving and operating a live product.

What you'll do

• Build production agents and expand their capabilities through prompts, tool use, orchestration, new models and MCP integrations.
• Design and operate reliable backend systems for asynchronous creative generation and long-running tasks, with strong performance, observability, scalability and security.
• Develop shared evaluations and live quality monitoring, including model-based assessment of image and video outputs.
• Own features end to end, from identifying user needs and prototyping to shipping across the stack and supporting them in production, alongside product, design and engineering.
• Help shape both what the agent can do and how people use it across ElevenCreative.

What you'll need

• Strong backend engineering skills.
• Experience operating production systems.
• Sound fundamentals in APIs, cloud infrastructure, storage and asynchronous processing.
• Hands-on experience developing agents.
• An understanding of prompts, tools, execution logic, evaluations and the challenges of reliable, secure operation.
• Evidence of independent, end-to-end ownership and confidence working across the stack, including frontend delivery when needed.
• Good product judgement, clear communication and enthusiasm for creative agents.
• Exceptional engineering evidenced by products you have shipped, difficult problems you have solved and systems you have owned.

Nice to have

• Familiarity with HTTP, WebSockets and asynchronous workers.
• Experience with multimodal generation, creative editors, MCP, or building products in a small, fast-moving team.

Details

• Remote.
• The work includes building and operating a live product.
