Staff Backend Engineer- Agent Experience (AX)

📋 Description Build agent-facing surfaces: API-first provisioning, M2M auth, scoped credentials. Own MCP servers and an agent-first CLI for agents and LLMs. Harden the agent media path for reliable uploads by non-human callers. Make agent behavior measurable with instrumentation and attribution. Work across Node.js/TypeScript, Ruby/Rails, and Go in the core platform. Ship, measure, iterate with cross-functional teams across Product, Ecosystem, and Discoverability. 🎯 Requirements 10+ years building and operating production backend systems and APIs at scale. Strong in Node.js/TypeScript; comfortable with Ruby/Rails and/or Go. Strong API and protocol design: OAuth, API keys, versioning, idempotency, rate limiting. Genuine curiosity about agents and LLMs and how they're reshaping software. Distributed systems and cloud instincts (AWS or equivalent). Ownership mindset: scope problems and ship. Clear written communication for machine consumers and distributed teams. 🎁 Benefits Hands-on experience with MCP, LLM tool/function-calling, or building AI-/agent-native products. Experience building SDKs, CLIs, or developer tools used by engineers. Background in media, imaging, or video processing/delivery. Open-source contributions in the agent or developer-tooling ecosystem.
