Senior / Staff AI Platform Engineer

About the Role

Suno's song creation agent is becoming something other teams build on. As a Senior AI Platform Engineer, you'll build the APIs, SDKs and shared tooling, including eval infrastructure, tracing and model routing, that let engineers across Suno ship agent features faster. You'll work closely with the agent team, partner teams and Infra, and your customers are other engineers, so adoption is a measure of success. You'll help shape the platform as it grows.

What You'll Do

• Design and build the platform APIs and SDKs that other teams use to build agent features.
• Develop shared eval infrastructure, including the eval runner, results storage and dashboards, and help the team decide what to build and what to buy.
• Implement end-to-end tracing and observability, so any request can be followed across services from prompt to audio.
• Manage model provider routing, fallback, rate limits and cost controls.
• Partner with engineering teams across Suno to onboard them onto the platform with docs and hands-on support, and with Infra on the reliability and scale of the agent runtime.
• Help more people turn ideas into music by making it faster and safer for teams across Suno to ship agent features.
