As a Senior Software Technical Product Manager at Illumina, you will drive software design decisions for sequencing instrument platforms by translating user needs into product concepts and requirements. You'll collaborate with cross-functional teams (firmware, hardware, test) on release planning, backlog prioritization, and requirements management while creating wireframes, workflow diagrams, and formal specification documents. The role requires deep involvement in use case development, competitive analysis, risk identification (FMEA, cybersecurity), and Voice of Customer advocacy across clinical, research, and applied segments. You'll manage scope and change control for multiple concurrent instrument development efforts while ensuring compliance with medical device regulations (IEC 62304, FDA guidance) and best practices in formalized requirements engineering.
