Senior / Staff AI Platform Engineer

Job summary

Responsibilities

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.

• 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.

What they're looking for

• 4–6 years building and scaling backend or platform systems in production, in any language.
• Experience on a team that supports other developer teams, including building a platform, API or SDK that other teams adopted.
• Experience with production LLM or agent systems, for external or internal users.
• Depth in distributed systems and observability, including tracing across services.
• Comfort working with internal customers: scoping with partner teams, earning adoption and handling ambiguity.
