Senior / Staff Full-Stack AI Engineer

Job summary

Responsibilities

Suno's song creation agent takes a plain-language request, plans the steps, and calls our music models and audio tools to make the song. We're hiring Senior / Staff Full-Stack / AI Engineers to build the backend, data and evals behind it, working alongside ML engineers, PMs and the product teams…

• Build and run the backend for an AI agent that plans multi-step requests and calls music models and audio tools.
• Design the evals, datasets and release gates that decide whether a change to the agent ships, and make the call when the results are noisy.
• Develop the data pipelines that feed the agent and its evals, working alongside ML engineers.
• Create internal tools for running and reviewing evals.
• Share on-call and launch support for a high-traffic production system, and help the team ramp new engineers as it grows.

What they're looking for

• 4–6 years building and scaling general backend systems in production, in any language: services at scale, observability and on-call ownership.
• Experience shipping and operating an LLM-powered agent or feature in production, for external or internal users, with multi-step tool calling.
• Experience building evals for nondeterministic systems, such as regression sets, graders or LLM judges, and using the results to decide what ships.
• Comfort on a small team that runs production: handling ambiguity, unblocking yourself, and working with ML engineers, PMs and partner teams.
