Job summary

Suno is building a world where anyone can create music with AI-powered tools. We are hiring a Senior AI Platform Engineer to design APIs and SDKs, build eval infrastructure, and ensure observability across the agent runtime. You will partner with Suno teams to drive adoption and scale the platform.

You will collaborate with Infra and product teams to deliver reliable, fast APIs, routing, and model management, enabling engineers to ship agent features safely and rapidly.

Qualifications

• 4–6 years building and scaling backend or platform systems in production.
• 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.

Responsibilities

• 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.
