Senior Engineer, Systems Design – Systems Integration & Test, Flow Cytometry

Work Schedule Standard (Mon-Fri) Environmental Conditions Laboratory Setting, Office Job Description Description Thermo Fisher Scientific is seeking a highly motivated and experienced Senior Engineer, Systems Design to join our engineering team supporting the Flow Cytometry platform . This role will focus on system-level integration and hands-on engineering testing , ensuring that complex subsystems work together effectively as an integrated product. The successful candidate will lead systems integration activities, execute engineering tests, troubleshoot cross-functional issues, support feasibility and concept studies, and assess technical risk for sustaining changes. The role requires strong systems thinking, test discipline, data-driven problem solving, and hands-on laboratory capability . Prior systems integration experience is strongly preferred; candidates with strong test experience who can demonstrate systems thinking and a willingness to develop systems integration expertise are also encouraged to apply.

Drive execution of systems integration activities for Flow Cytometry system, coordinating interfaces and interactions across microfluidics, acoustics, optics , electronics, firmware/software and other applicable subsystems. Plan and perform hands-on engineering testing for feasibility studies, concept evaluation, integration checkout, troubleshooting and sustaining investigations. Execute controlled system configurations and integrated workflows; identify interface, timing, performance and cross-subsystem issues that may not be visible during standalone subsystem testing. Lead structured integration issue triage and root-cause investigations by reproducing, isolating and characterizing failures, analyzing evidence, and working with appropriate design and test teams through resolution. Analyze experimental and test data using appropriate statistical and engineering methods; identify trends, variation and failure mechanisms and translate results into clear technical conclusions and recommendations. Assess integration coverage, identify test or interface gaps, and support development of test methods, acceptance criteria and requirements-to-test traceability. Perform technical risk and integration-impact assessments for sustaining changes , field issues and design modifications, and support risk-retirement testing and investigations. Support feasibility studies and proof-of-concept activities to evaluate new concepts, critical performance parameters and interface assumptions. Maintain clear integration configuration, test results, known issues, residual risks and readiness evidence, and support handoff of an integration-ready system to formal V&V. Collaborate closely with Systems Engineering, subsystem designers, Technical Leads, Hardware/Software/Embedded Test, V&V, Quality, Regulatory, Manufacturing and Service teams.

Bachelor's degree or higher in Bioengineering, Biomedical, Mechanical, Electrical, Electronics Engineering , or a related engineering/scientific discipline. Typically 5+ years of experience in systems engineering, design engineering, integration engineering or test engineering within new product development or sustaining engineering. Demonstrated hands-on test experience with complex instruments, electromechanical systems or multidisciplinary products. Systems integration experience is preferred. Candidates without direct integration experience must demonstrate strong systems thinking , learning agility, curiosity, and the ability to understand interactions and dependencies across multiple subsystems. Strong test engineering fundamentals, including test strategy and method development, experimental design, acceptance criteria, data analysis, statistical interpretation, troubleshooting and technical documentation . Strong analytical and problem-solving skills, including experience with root-cause analysis and engineering risk assessment such as FMEA or
