Senior Protocol Engineer

What You'll Own

We’re looking for builders who care about craft and love partnering across product, design, and go-to-market to ship quickly.

Responsibilities

• Translate heterogeneous marketplace schemas into resilient MCP/A2A adapters
• Build rate limiting, authentication, and telemetry guardrails into every integration
• Partner with security to threat-model agent abuse vectors before they reach production
• Own backwards compatibility for API and protocol changes across customer fleets
• Ship instrumentation that makes reliability and latency regressions impossible to miss

How We'll Measure Success

• P0 incidents per integration stay below 0.2 per quarter
• Regression test coverage for MCP adapters exceeds 95% critical paths
• p95 latency across agent handoffs stays under 600ms internationally
• Customer migrations to new protocol versions complete within 30 days of launch

Who You Are

We know great people come from non-linear paths. These signals help us understand how you’ve grown your craft.

Core Qualifications

• 7+ years building distributed systems or protocol heavy products
• Deep experience with TypeScript or Go and a second strongly typed language
• Confidence designing fault-tolerant services that run across regions
• Comfort working with OAuth/OIDC, HMAC signatures, and zero-trust principles
• Ability to dissect and normalize third-party API schemas quickly

Bonus Points

• Shipped agent client, RPA, or integrations products before
• Experience contributing to open protocol specifications
• Background working with event-streaming systems (Kafka, Pulsar, Kinesis)
