Job description

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

As a Staff Software Engineer on Suno’s new Bots & Fraud team, you’ll help lead the backend engineering behind our defenses against abuse, fraud, and bots. You’ll build real-time services that turn request telemetry, behavioral signals, and device and app attestation into enforcement, such as rate limits, challenges, and account actions, across every layer from the edge to product services. The team is new and pulls together work from across the company, so you’ll shape both what we build and how we build it. You’ll report to the Bots & Fraud Engineering Manager.

• Build the logging and metrics that show what’s getting through, what we block, and our false-positive rate.
