Technical Writer

Regulatory & Product Documentation · Medical Devices & Digital Health | Full-Time | Chennai (On-site)

Job Summary

RhythmRx is hiring a Technical Writer to support documentation across our portfolio of connected cardiac monitoring devices and digital health solutions. You will draft, format, and maintain clear, accurate documentation — spanning software and API references, mobile app guides, user manuals, and regulatory support materials. A strong emphasis of this role is software documentation: explaining device software, mobile applications, and integration workflows for both technical and non-technical audiences, while building strong regulated medical-device and compliance fundamentals.

Key Responsibilities

Software Documentation

Write and maintain software documentation: API references, SDK guides, developer notes, error/message references, and integration and configuration workflows.

Document mobile application behaviour and features across Android and iOS (screens, flows, settings, BLE/device connectivity).

Produce release notes, changelogs, and version histories aligned to software build cycles.

Create how-to guides, troubleshooting content, and in-app help/UX copy for technical and non-technical users.

Read and interpret source material — specs, tickets, code comments, and design docs — to document features accurately.

Use Markdown and docs-as-code workflows (Git-based repos, structured authoring) where applicable.

Product & User Documentation

Draft and format clear, user-centered content: clinical user manuals, operator guides, Instructions for Use (IFU), and installation/configuration guides.





Translate technical and clinical input into structured, understandable content for healthcare professionals, technicians, and internal stakeholders.

Update and revise existing documentation based on product changes and reviewer feedback.

Regulatory & Compliance Support

Support preparation of FDA- and ISO-aligned documentation under senior review.

Assist with document inputs referencing ISO 13485, ISO 14971, and IEC 62304.

Help maintain traceability records and organise documentation for audits and submissions.

Standards & Quality

Follow established templates, style guides, versioning, and document control practices.

Manage documents within version-management tools and Quality Management Systems (eQMS).

Contribute to usability testing and incorporate feedback to improve clarity.

Collaboration

Work with R&D;, Regulatory Affairs, Clinical Affairs, QA, and Product Management to gather and validate technical information.

Coordinate with senior writers to ensure consistency and quality across deliverables.

Requirements

2+ years of technical writing experience, or a strong portfolio / internship in a technical or regulated domain.

Excellent English writing and editing skills, with the ability to explain software clearly to varied audiences.





Demonstrated ability to write software or product documentation — API/developer guides, help content, release notes, or similar.

Comfort reading technical material (specs, code comments, UI flows) and turning it into structured content.

Familiarity with Markdown, Confluence, Git, and standard documentation/authoring tools.

Basic awareness of medical device or regulated-environment documentation standards.

Ability to follow document control, templates, and style guidelines.

Robust attention to detail and the ability to manage multiple tasks under deadlines.

Bachelor's or Master's in Biomedical Engineering, Life Sciences, Technical Communication, or a related discipline.

Preferred Experience

Exposure to ISO 13485, ISO 14971, or IEC 62304.

Awareness of FDA, HIPAA, or GDPR requirements.

Familiarity with the Common Technical Document (CTD) format.

Interest in SaMD (Software as a Medical Device) or digital health applications.

Hands-on experience with API documentation tools (OpenAPI/Swagger, Postman) or docs-as-code pipelines.

Familiarity with Agile/Scrum workflows and issue trackers (Jira, Linear).

Understanding of mobile apps, BLE/device connectivity, or basic programming concepts.

Familiarity with diagramming and visual content tools (Figma, draw.io, screen-capture).

Certification or coursework in Technical Communication, Medical Writing, or Regulatory Writing.
