About the Job

Requirements

  • Senior developer-advocacy experience, or senior technical partner-facing engineering experience in crypto, fintech, or a B2B API product.
  • Deep, hands-on command of REST and WebSocket APIs, including reading specifications and confirming behavior with a live call.
  • Ability to make hands-on code changes to quickstarts and SDKs, not only review them.

  • Credibility in direct technical partner conversations and ability to act as a senior escalation for a first line.
  • Ability to verify against official documentation and live behavior before approving any published API claim, and distinguish fact from assumption.
  • Structured, concise technical writing for partner-facing and internal product audiences.
  • Ability to mentor and enable junior team members.

Responsibilities

  • Own the change-request flow by authoring requests that alter API behavior or contract and remaining the named approver; Junior DevRels handle intake, reproduction, and evidence.
  • Propose API improvements based on partner and internal-developer feedback and carry them into Product as structured requests.
  • Provide API and infrastructure advocacy for partners and the developer audience.
  • Serve as the named approver on published API claims and own the correctness of guides and quickstarts that require specification review or live-call verification.
  • Own the safety bar for AI/agent or hosted surfaces in scope, including what they must not expose.
  • Keep quickstarts correct and make hands-on fixes while the first line ramps.
  • Teach and enable Junior DevRels to update and maintain quickstarts and progressively maintain SDKs.
  • Hold partner-call depth and technical feedback.
  • Act as the senior technical escalation for the Junior/operations first line on subject-matter and blocked issues.

Desired Qualifications

  • Crypto-exchange or exchange-integration experience, including market making, custody, payments, or on/off-ramp.
  • Experience owning an SDK or AI/agent surface, including safety review, packaging, and registries.
