What You Will Be Doing

• 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.
