Staff Backend Engineer- Agent Experience
📅 Jul 7
Node.jsTypeScriptRubyGo
📜 Description
- Build the surfaces agents call directly: API-first account provisioning, machine-to-machine authentication, scoped credentials, and agent-level identity and attribution.
- Own our MCP (Model Context Protocol) servers and an agent-first CLI for reliable agent discovery and invocation.
- Harden the agent media path to ensure reliable uploads and core media operations for non-human callers.
- Make agent behavior measurable through instrumentation, signals, and attribution.
- Work across a polyglot backend using Node.js/TypeScript, Ruby/Rails, and Go.
- Prototype quickly, dogfood the experience, and represent the agent's perspective in design decisions.
🛠️ Requirements
- 10+ years building and operating production APIs, SDKs and Backend systems and at scale.
- Strong in Node.js/TypeScript, and comfortable working in (or quickly ramping on) Ruby/Rails and/or Go.
- Deep API and protocol design fundamentals — authentication (OAuth, API keys, scoped permissions), versioning, idempotency, rate limiting, clean contracts.
- Genuine curiosity about agents and LLMs and how they're reshaping how software gets built and run.
- Solid distributed-systems and cloud instincts (AWS or equivalent).
- A bias for ownership in ambiguity — you scope the problem, not just the solution, and you ship.
- Strong written communication — it matters more than usual when your consumers are machines and your teammates are distributed.
