Senior Technical Writer & Specifications Analyst

The Senior Technical Writer & Specifications Analyst is a hybrid role responsible for performing technical business analysis—including requirements gathering and data mapping—and translating those requirements into high-quality, developer-facing API specification documentation. This individual owns the complete lifecycle of documentation for our integration and interoperability services, including orders and results services. Working directly with clinical, technical, product, and analysis teams, they will define data specifications, construct mapping sheets, and build clear, user-friendly documentation to help both internal consumer teams and external customers seamlessly integrate with Quest systems. The ideal candidate has deep expertise in healthcare standards (HL7 and FHIR) and a proven background in simplifying complex integration workflows.

Responsibilities

Partner with technical, development, and product teams to gather, define, and document technical requirements for new and existing interoperability services.

Create and maintain comprehensive, interactive API specification documentation (including schemas, endpoints, headers, and error codes) specifically for orders and results services.

Perform detailed data mapping, interface specification design, and clinical data flow analysis (e.g., mapping HL7 segments/fields and FHIR profiles).

Develop and maintain technical guides, quick-starts, step-by-step tutorials, and release notes for both internal developers and external customer IT teams.

Validate technical specifications by actively testing APIs (using tools like Postman or cURL) and reproducing integration workflows to ensure accurate documentation.

Implement and manage a "Docs-as-Code" workflow, utilizing version control and markdown formatting to streamline review cycles and updates.

Collaborate during Agile backlog grooming and sprint planning to proactively identify documentation and interface specification needs early in the product lifecycle.

Standardize content across integration portals to ensure consistency, clarity, and adherence to both industry interoperability standards and brand style guides.

Promote an environment that encourages collaboration, initiative, continuous improvement, learning, and the generation of innovative ideas and solutions.
