Sr. System Engineer

Job description

Work Schedule Standard (Mon-Fri) Environmental Conditions Office Job Description At Thermo Fisher Scientific, our Mission is to enable our customers to make the world healthier, cleaner and safer. Join a multidisciplinary R&D team developing reliable instruments that help customers advance research, improve analytical results and solve practical laboratory and inspection challenges. Role overviewAs Senior Systems Engineer, you will bring a strong electrical engineering background to the development of life science and chemical analysis instruments and related inspection systems. Your primary responsibility will be hands-on electrical subsystem and printed circuit board assembly (PCBA) design, from requirements and circuit architecture through board bring-up, verification and production transfer. You will work with the R&D Manager and firmware, mechanical and applications engineers to ensure the electronics meet system performance and integration requirements. The development portfolio includes EDXRF instruments, the Varioskan ALF Multimode Microplate Reader, X-ray inspection systems and the Power Blotter Station. Assignments will depend on project needs and relevant expertise. Key responsibilities·       Translate instrument requirements into electrical specifications, circuit architecture, interface definitions and measurable board-level acceptance criteria. ·       Design analog, digital and mixed-signal circuits, including sensor interfaces, signal conditioning, ADCs/DACs, embedded control, power regulation and actuator interfaces. ·       Perform component selection, circuit calculations and simulation; develop schematics and controlled engineering BOMs using tools such as Altium. ·       Develop or guide PCB layout, including stack-up, component placement, grounding, signal/power integrity, thermal behavior and EMC considerations. ·       Bring up prototype PCBAs, measure circuit performance and debug power, signal, timing, noise and communication issues with firmware engineers. ·       Develop electrical verification plans, test fixtures and procedures; assess accuracy, noise, stability, timing, power and fault behavior against requirements. ·       Integrate PCBAs, power supplies, sensors, detectors, motors and cabling; resolve electrical interfaces with mechanical and firmware teams. ·       Address electrical safety, protection, isolation and interlock requirements with system and compliance specialists, as applicable to the product. ·       Apply design for manufacture and test; support contract manufacturers with PCBA fabrication/assembly data, test coverage, pilot builds and yield issues. ·       Maintain design records and engineering changes; investigate failures, manage component risks and support manufacturing and service throughout the product lifecycle. Required qualifications·       Advanced degree plus at least 3 years of relevant experience, or bachelor's degree plus at least 5 years, in electrical/electronic design and product development. ·       Degree in Electrical Engineering, Electronics Engineering or a closely related discipline with substantial circuit design training. ·       Demonstrated hands-on PCBA development from requirements and schematics through PCB layout review, board bring-up, verification and production release. ·       Strong analog, digital and mixed-signal design skills, including signal conditioning, data conversion, embedded processor interfaces and power circuitry. ·       Proficiency in schematic capture and PCB design tools such as Altium, plus circuit simulation and component selection. ·       Practical understanding of grounding, low-noise design, signal/power integrity, EMC and electrical protection, with ability to apply relevant design constraints. ·       Hands-on use of oscilloscopes, multimeters, power supplies, logic analyzers and other equipment for circuit characterization and debugging. ·       Experience with requirements, electrical interfaces, design verification, root-cause analysis and controlled design documentation and change management. ·       Ability to own electrical work packages, support peers and communicate effectively in English with global, cross-functional teams. ·       Ability to travel as needed for suppliers, manufacturing builds and collaboration with global teams. Preferred qualifications·       Electronics development for life science and chemical analysis instruments, spectroscopy, optical detection, X-ray equipment or laboratory automation. ·       Experience with precision low-level signals, detector electronics, motor drives, controlled power delivery or high-voltage interfaces relevant to the assignment. ·       Python, MATLAB or LabVIEW for test automation and data analysis; experience with statistical analysis and DOE. ·       Experience with PCBA DFM/DFT, automated production testing, component lifecycle management and product safety or EMC pre-compliance testing. ·       Familiarity with AI-assisted tools for engineering tasks such as analysis, documentation, or coding is a plus.
