Principal Power Electronics Engineer Jobs in Rochester, MI

The Senior Electronics Cost Estimating Engineer is the corporate subject matter expert for electronics cost estimating, design-to-cost architecture, and competitive electronics benchmarking. This role leads the electronics technical and cost-estimating activities associated with new customer RFQs, engineering changes, awarded programs, competitive teardowns, and reverse-engineering studies. The engineer reviews customer RFQ packages, identifies and interprets applicable electronics requirements, and works with assigned Electronics and Systems Engineers to develop the lowest-cost compliant electronic architecture, preliminary schematic, and costed electronic Bill of Materials (eBOM).

The position requires a senior-level electronics engineer who can move between requirements analysis, system architecture, circuit design, component selection, Altium schematic/eBOM development, component costing, PCB/PCBA manufacturing cost analysis, supplier engagement, reverse engineering, and management-level cost communication. The engineer serves as the primary Electronics Engineering interface between Engineering, Purchasing, global manufacturing teams, and the electronics supplier base for cost and quotation activities.

This engineer is expected to lead estimating workstreams, guide supporting engineers, challenge unnecessary cost and architecture complexity, apply lessons learned from teardown activities, and provide technically defensible cost estimates - often under aggressive RFQ timing, including occasional turnaround requirements of less than 24 hours.

• Assign accurate component pricing to engineer-generated eBOMs using direct supplier quotations, Purchasing-negotiated pricing, approved internal pricing, distributor/market pricing, and appropriate volume-based assumptions.
• Maintain traceability of pricing source, quantity or annual-volume assumptions, manufacturer part number, and quotation basis.
• Evaluate costs for major electronics commodities including LEDs, MCUs, LED drivers, power ICs, regulators, transceivers, MOSFETs, protection devices, connectors, magnetics, capacitors, resistors, and related components.

• Produce clear cost-per-PCBA, cost-per-lamp, and cost-per-vehicle estimates as required, with documented assumptions, exclusions, open issues, and quote risks.

• Lead or support reverse engineering and competitive teardown activities for customer, competitor, benchmark, and existing production electronic designs.
• Analyze electronic assemblies, PCBAs, component selections, PCB construction, interconnect strategies, thermal solutions, and system architectures to understand how benchmark designs achieve their functional requirements.
• Reverse engineer designs sufficiently to identify major circuit functions, power-supply and power-conversion strategies, microcontroller and communications architecture, LED-driver topology, diagnostics/protection strategies, PCB technology and construction, connector strategy, key components, and manufacturing approach.
• Develop costed reverse-engineered eBOMs using identified components, equivalent components, supplier information, distributor pricing, internal pricing, and manufacturing assumptions.
• Estimate total electronics and PCBA cost of benchmark designs, including component, PCB, assembly, programming, testing, and manufacturing costs.
• Compare reverse-engineered designs against FNG designs to identify differences in component count, architecture complexity, PCB size/construction, LED and driver utilization, power-conversion strategy, MCU/communications strategy, interconnect approach, manufacturing complexity, and overall cost.
• Identify design-to-cost lessons learned from teardown and benchmarking activities and translate them into actionable recommendations for current and future programs.
• Propose architecture simplifications, component substitutions, circuit consolidation, PCB reductions, manufacturing improvements, and other optimization opportunities based on benchmark findings.
• Maintain and communicate benchmark findings and lessons learned so effective concepts can be considered in future RFQs and product development while respecting customer requirements, reliability, validation, intellectual-property considerations, and FNG engineering standards.
