Summary

We're looking for a API Technical Writer to create and maintain developer-facing documentation for our API products in a healthcare/SaaS environment. This role partners closely with Product and Engineering to produce API documentation, release notes, and customer-facing content for minor and major releases. The ideal candidate has real development experience, is comfortable working inside engineering workflows (not just editing docs after the fact), and can champion a document-first approach to API development. What You’ll Do • Create and maintain API documentation and customer-facing release notes for minor and major product releases in partnership with Product and Engineering teams. • Apply OpenAPI Specification (OAS 3.0) standards and champion a documentation-first approach, ensuring API contracts are clearly defined and aligned before development begins. • Write and maintain documentation in Markdown using Git-based workflows and participate in GitHub release and publishing processes. • Test and interact directly with REST APIs to validate functionality and create accurate examples and documentation (e.g., curl). • Explore opportunities to leverage AI and automation to improve documentation quality, maintenance, and API change tracking. • Independently gather information through hands-on experimentation and collaboration with subject matter experts to create technical documentation and process guides. • Maintain and organize technical reference materials, research, design specifications, and other documentation assets. • Continuously evaluate and improve documentation, partnering with Customer Success, Support, and customers to identify content gaps and enhance the developer experience. What You’ll Bring • Experience creating and maintaining developer-facing API documentation. • Working knowledge of the OpenAPI Specification (OAS 3.0) and API contract-based development practices. • Experience working in GitHub, including pull requests, branching strategies, and release/publishing workflows. • Strong Markdown writing skills and experience with Git-based documentation platforms. • Ability to call, test, and experiment with REST APIs and document JSON request/response payloads. • Experience creating API examples using curl; experience with JavaScript, Java, PHP, or similar languages is a plus. • Strong technical writing skills with the ability to translate complex product and engineering concepts into clear, accurate, and user-friendly documentation. • Demonstrated ability to independently learn technical systems and drive documentation efforts with minimal oversight. • Ability to thrive in a fast-paced, collaborative SaaS environment. Preferred Qualifications • Prior experience in healthcare and SaaS environments. • Familiarity with healthcare data and interoperability concepts, including PHI handling, patient identifiers, NPIs, and clinical workflow terminology. • Experience documenting integrations with EMR/EHR platforms such as Epic. • Ability to read and understand production code, API implementations, and system integrations. • Hands-on software development experience writing or maintaining production applications, APIs, or integration solutions. • Familiarity with TypeScript and/or JavaScript. • Experience serving in a hybrid Technical Writer, Documentation Engineer, or Developer Documentation role. • Interest in AI-assisted documentation workflows, content automation, or API change-tracking solutions.
