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

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.

Responsibilities

• 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.

Required Qualifications

• 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 equivalent methods.

• Working knowledge of systems engineering/product-development practices, including requirements, interfaces, traceability, design controls and verification concepts.

• Ability to communicate technical findings clearly and collaborate effectively across multidisciplinary teams.

Preferred: Experience in life-science or analytical instrumentation, flow cytometry, or direct experience with the Attune platform or its microfluidic, acoustic or optical subsystems.
