ROLE SUMMARY
The Senior Systems Engineer is a senior individual contributor responsible for providing deep technical expertise across the full lifecycle of IVD instrument development and commercialization. This role sits at the intersection of engineering rigor, regulatory compliance, and field excellence, supporting activities that span risk management, analytical validation, document authorship, project management. The ideal candidate brings a strong track record of building and releasing IVD instruments under FDA/ISO design controls, firsthand immunoassay platform experience, and the technical versatility to lead both lab-bench validation work and field deployment activities. This is a highly cross-functional role requiring collaboration with R D, Quality, Regulatory, and Commercial teams.
WHAT YOU'LL DO
Lead and maintain risk management documentation (FMEA, Hazard Analysis, Risk Benefit Analysis) in accordance with
ISO 14971
throughout the product lifecycle. Identify, assess, and mitigate technical risks associated with instrument design, reagent-instrument interface, and clinical use scenarios. Support design review processes by providing risk-informed input across mechanical, electrical, optical, and software subsystems. Evaluate field failure data and complaint trends to drive corrective and preventive actions (CAPAs) back into design and risk files. Author, review, and maintain design control documentation including System Requirements Specifications (SRS), Design Input/Output documents, Verification & Validation (V&V) protocols, and summary reports. Maintain Design History File (DHF) completeness and traceability matrices across hardware, software, and consumable design elements. Draft and revise SOPs, work instructions, test methods, service bulletins, and engineering change orders (ECOs) in compliance with QMS requirements. Produce clear, technically rigorous reports suitable for regulatory submissions (510(k), PMA supplements, CE Technical Files). Design and execute analytical validation studies including precision, accuracy, linearity, interferent studies, and method comparison for immunoassay-based assays and instrument platforms. Apply CLSI guidelines (EP05, EP06, EP09, EP15, EP17) and relevant IVD standards to study design and data interpretation. Collaborate with reagent development and assay teams to characterize reagent-instrument interactions and define release specifications. Generate and defend analytical validation packages in support of regulatory submissions and customer site qualifications.
