Senior Technical Writer

About the Role:

We're seeking a Senior Technical Writer to create clear, accurate, and developer-friendly technical documentation that transforms complex API specifications and code into comprehensive guides. This role bridges engineering and documentation, specializing in API reference documentation, integration guides, and code-to-doc workflows using industry standards like OpenAPI Specification (OAS).

The Senior Technical Writer produces high-quality content deliverables including API reference documentation, SDKs, how-to guides, tutorials, and code examples.

What You'll Do:

Content Creation & Deliverables

• Create comprehensive API documentation from OpenAPI Specification files, including endpoint descriptions, parameters, authentication, error handling, and code examples
• Develop SDK documentation that guides developers through library installation, configuration, and implementation
• Write integration guides and tutorials that walk developers through common use cases step-by-step
• Produce how-to guides focused on practical developer workflows and implementation patterns
• Create code examples in multiple languages (JavaScript, Python, Go, etc.) that demonstrate API usage
• Document webhooks, authentication mechanisms, and best practices for API consumption

Technical Competency

• Manage code-to-doc workflows, including parsing and organizing API specifications using tools like Swagger/OpenAPI
• Leverage generative AI tools (ChatGPT, Copilot, Claude, specialized API doc generators) to accelerate initial documentation drafts from code, OpenAPI specs, and code samples
• Evaluate and refine AI-generated content for accuracy, completeness, clarity, and alignment with company voice and standards
• Understand when and how to use AI effectively in documentation workflows—from generating initial reference documentation to creating code examples and tutorials
• Collaborate with engineering teams to extract technical information, clarify undocumented behavior, and ensure accuracy
• Understand API design principles (REST, GraphQL concepts) and communicate them clearly to developers
• Work with version control systems (GitHub) to manage documentation updates alongside code releases
• Implement and test code samples for accuracy and functionality
• Stay current with API documentation best practices and emerging tools in the developer documentation space, including AI-assisted documentation generation

Content Consistency & Quality

• Maintain documentation consistency across API endpoints, SDKs, and guides
• Implement and adhere to documentation style guides for terminology, formatting, and code sample conventions
• Audit existing API documentation for completeness, accuracy, and technical debt
• Contribute to documentation standards and best practices across the organization

Who You Are:

Required

• 10+ years of technical writing experience
• Portfolio demonstrating strong API reference documentation and code examples
• Proven experience with OpenAPI Specification and REST APIs
• Proficiency with GitHub and markdown-based documentation workflows
• Strong working knowledge of at least 2-3 programming languages

Preferred

• Experience documenting SDKs or client libraries
• Familiarity with code-to-doc automation tools or processes, including AI-assisted documentation generators
• Portfolio examples showing use of generative AI to accelerate documentation creation
• Experience evaluating and improving AI-generated technical content for accuracy and quality
• Contributions to open-source documentation projects
• Experience with documentation analytics and user feedback integration
• Familiarity with developer relations or developer experience workflows
• Experience with ReadMe, MkDocs, or similar documentation platforms
• Knowledge of prompt engineering techniques for generating quality API documentation and code examples
