Role Title: API Technical Writer

Experience Level: 3–7 years

Role Overview

Responsible for creating clear, accurate, and developer-friendly API documentation aligned with OpenAPI specifications and Redocly-based publishing workflows.

Key Responsibilities

  • Write and maintain API documentation (reference + guides)
  • Convert OpenAPI specs into structured, readable documentation
  • Create onboarding guides (authentication, sandbox usage, workflows)
  • Develop examples (requests/responses, use cases)
  • Collaborate with API specialists to resolve inconsistencies
  • Ensure documentation aligns with actual API behavior
  • Maintain documentation using Git-based workflows (PRs, versioning)
  • Payments Knowledge: Must have understanding of Payments Merchant Services, API key provisioning, and API /integration requirements of sandbox vs. production environments for payments gateways.
  • Persona-Based Writing: Ability to pivot tone and complexity between a \"Business User\" looking for value and an \"External Developer\" looking for syntax.
  • Structure documentation for AI consumption (LLMs), ensuring prompt-driven workflows and machine-readable task guidance.
  • Manage the end-to-end documentation lifecycle using GitHub-based workflows, ensuring all artifacts are optimized for Redocly’s rendering engine.
  • Cross-Functional Strategy: Partner with Product and Design to create \"Service Blueprints\" that map the user journey from discovery to production.

Required Skills

  • Strong Markdown writing skills
  • Experience with API documentation (REST APIs)
  • OpenAPI 3.x understanding (read/write/edit specs)
  • Git / GitHub workflows (branching, PRs)
  • JSON / YAML familiarity
  • Experience with tools like:
  • Redocly / Swagger / Postman / Stoplight

Good to Have

  • Experience with docs-as-code systems
  • Familiarity with developer portals
  • Basic understanding of authentication (API keys, OAuth2)
  • Ability to write for both technical and semi-technical audiences

What Success Looks Like

  • Clear, self-service documentation requiring minimal support
  • Reduced onboarding friction for developers
  • Consistent, accurate API documentation across all endpoints
