About Suno

We're building the world's first creative entertainment platform, where the entire world can feel the joy and fulfillment of making music. Music is for everyone: Our users include everyone from grandmothers creating songs for their loved ones, to Grammy winners using Suno Studio, our power tool, to make the most popular hits in the world.

Building the future of entertainment requires ambition. The pace is fast, the problems are hard, and the work demands ownership and intensity. For the right people, it’s incredibly rewarding: a chance to shape a new medium, work with a small team that cares deeply about quality, make music, drink too much coffee, and build something that millions of people use to express themselves in ways that were never before possible.

Suno is the fastest growing consumer entertainment company and the leader in AI music. We are backed by leading investors including Bond Capital, Menlo Ventures, Lightspeed Venture Partners, IVP, Forerunner, Union Square Ventures, Alkeon, Quiet, Matrix Partners, Schroders Capital and, NVentures (venture arm of NVIDIA).

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.
