The Sr. Electrical Engineer is responsible for developing moderate to complex electrical system designs for new products as well as design improvements for legacy products. Responsibilities also include exercising sound engineering judgement, presenting analysis summaries which support design decisions, and coaching R&D staff. This experienced position leads the development of complex electrical subsystems and plays a key role in system integration, and technical execution.

The Sr. Electrical Engineer will own the full hardware development cycle, from concept through design, validation, and integration. Deep expertise in signal integrity, electrical noise mitigation, and real‑time interface design is essential to the expectations of this role. The Sr. Electrical Engineer works both independently and in a team environment with Electrical Engineers, Software Engineers, Design Engineers, NPI Managers, and Test Technicians.

They frequently initiate collaboration with all departments within R&D.

• Develop innovative architectures which focus on performance, reliability, and compliance. Own design verification, prototyping, and system‑level integration, with a strong emphasis on field bus and communication protocol implementation at the circuit level. Expert level understanding of the Altium design tool and generation of technical data.
• Conduct in-depth design reviews, perform detailed signal integrity and power integrity analysis, and mentor less senior Engineers in best practices.
• Supervise and develop complete electrical system level designs through the PLM system.
• Contribute technical leadership to R&D projects in a team setting to meet project cost targets, budget requirements and delivery dates.
• Develop verification test plans, check the accuracy of test results, and draw logical conclusions.
• Drive manufacturability and cost optimization across electrical systems by resolving complex DFM challenges, engaging with vendors, and guiding design strategy to meet production and cost targets.
• Apply industry best practices for manufacturability as well as identify and implement new technologies.
• Drive Continuous Improvement in technical information i.e., process records, schematics drawings, SOP’s, prototype, and fixture drawings as needed to evaluate and support product design operations.
• Deliver electrical engineering support across the organization and to external vendors, ensuring timely resolution of technical issues that impact design, production, or product performance.
• Perform circuit simulation and analysis using industry‑standard tools to validate design performance and support troubleshooting throughout the development process.
• Assume technical ownership within the SIG SAUER NPI (New Product Introduction) process.
• Design and schematic drawing checker for other Electrical Engineers in R&D.
• Provide mentorship to less experienced Engineers, sharing expertise and promoting collaboration across teams and disciplines.
• Participate in and sustain 5S Standards.
• Engage in and actively volunteer for continuous improvement projects and tasks.
• Must follow all required ISO procedures, comply with all work exposure EH&S training…
