Hardware Engineer – Automatic Transfer Switch (ATS)

We are seeking an experienced Senior Hardware Engineer to design, develop, and support reliable power transfer solutions used in critical power applications. This role focuses on the electrical and electronic hardware design of ATS systems, including power switching, sensing, protection, and control interfaces, ensuring compliance with safety and performance standards. The ideal candidate has strong experience in power electronics, low- and medium-voltage power systems, and electromechanical control design, with hands‑on involvement from concept through production. The position is located at DSE headquarters in Hunmanby (North Yorkshire).

Key Responsibilities

• Design and develop ATS hardware architectures including power paths, switching elements (contactors, breakers, SCRs, or solid‑state devices), and auxiliary control circuits.
• Create schematics, PCB layouts, and wiring diagrams for ATS control and monitoring systems.
• Design circuits for voltage, current, frequency sensing, phase detection, and power quality monitoring.
• Implement protective circuits for over‑current, over‑voltage, short‑circuit, and fault isolation.
• Support integration of microcontrollers, relays, and communication interfaces (Modbus, CAN, Ethernet).
• Ensure ATS designs meet UL, IEC, BS, and regional standards.
• Perform fault analysis, derating calculations, creepage/clearance analysis, and thermal design.
• Support short‑circuit withstand and closing ratings (WCR) and coordination studies.
• Collaborate with compliance teams during certification testing and audits.
• Develop and execute hardware validation plans including functional, environmental, and stress testing.
• Perform lab testing with generators, utility sources, and load banks; analyze test data, debug hardware issues, and implement design improvements.
• Support prototype builds, design for manufacturability (DFM), and design for test (DFT).
• Work with suppliers and manufacturing teams on component selection and cost optimization.
• Provide production support, failure analysis, and field issue resolution.

Requirements

• 7+ years of experience in electronics/electrical design.
• Strong experience in power electronics and low/medium voltage power systems.
• Experience in electromechanical control design and schematic capture/PCB design tools (Altium, OrCAD, CADstar, etc.).
• Proficiency with oscilloscopes, power analysers, and high‑power lab equipment.
• Hands‑on experience with analogue hardware design, signal conditioning, and processing.
• Knowledge of PCB design & layout requirements, especially with respect to EMC.
• Experience with CAD design tools and analogue/digital design.
• Experience defining task breakdowns and providing estimates.
• Excellent team player with problem‑solving and troubleshooting capabilities.
• Willingness to travel, including to the US‑based parent company.
• Working knowledge of compliance and safety standards (UL, IEC, BS).
• Bachelor’s degree in Electronic, Electrical Engineering or equivalent.

Benefits

• 25 days holiday + Bank Holidays.
• New flexible holiday scheme.
• Bupa Healthcare package.
• Life Insurance.
• Enhanced Maternity/Paternity pay.
• 5% Pension contributions.
• Company‑wide performance‑based annual bonus scheme.
