iRhythm’s Product Development team is seeking a highly skilled Software Engineer II to join our Lifecycle (Sustaining) Engineering team. This role focuses on supporting existing products through their lifecycle, ensuring quality, compliance, and continuous improvement while maintaining business continuity. In this role, you will own and execute product firmware & tooling software changes that keep our released medical device products safe, compliant, manufacturable, and reliable.

You’ll work closely with our product development team of embedded firmware and software engineers and cross-functionally with hardware, quality, and operations to resolve field and factory issues, manage obsolescence, improve yield, and maintain regulatory compliance. This opportunity offers substantial career growth potential while positively impacting lives through design and technology.

• Own software changes across released manufacturing equipment including bug fixes, minor feature enhancements, refactors, and obsolescence-driven updates working within established design controls and change management processes.
• Lead software updates to manufacturing test systems (fixture software, functional test scripts, ICT/boundary scan integration) and drive improvements to yield, throughput, and reliability.
• Integrate embedded firmware with hardware (board bring-up, driver updates, peripheral interfaces), using oscilloscopes, logic analyzers, JTAG/SWD, and in-circuit debuggers for root cause and verification.
• Lead firmware/software investigations for field returns, NCRs, and deviations; perform structured root cause analysis; implement and verify CAPA actions with clear traceability.
• Author and execute V&V (unit/integration/system), including test plans, protocols, automated regression suites, and reports compliant with IEC 62304 and internal SOPs.
• Maintain configuration management (requirements, code, test assets, DHF/DMR updates, SBOMs), ensuring complete documentation and traceability through release.
• Perform risk management activities (ISO 14971), update hazard analyses, perform impact assessments for changes, and ensure risk controls remain effective post-change.
• Validate software used in production (CSV/IQ/OQ/PQ as applicable), ensuring alignment with 21 CFR 820.70(i) and Part 11 for electronic records/signatures.
• Collaborate cross-functionally with Hardware, Quality, Regulatory, Manufacturing, Supply Chain, and external suppliers/CMs to plan and execute changes with minimal disruption.
• Support embedded software development and updates, ensuring compatibility with hardware and compliance with IEC 62304 and cybersecurity requirements.
• Contribute to secure product maintenance by assessing and implementing vulnerability patches, managing third‑party dependencies current in line with evolving guidance.

• BS in Computer Engineering, Computer Science, or related field
• 3+ years of experience embedded software development (C/C++), including hardware bring-up, low-level drivers, and board-level debugging within the medical device or regulated industry, manufacturing support a plus.
• Strong testing discipline: unit/integration/system testing, test automation, static analysis, code reviews, and documented V&V…
