Job description

We are looking for a Senior Electrical Hardware Engineer with practical experience in PCB design, power circuit design and DC-DC converter development. You will take ownership of electrical and electronic hardware development, from circuit design and component selection through prototype bring-up, testing and validation. This role suits an engineer who enjoys hands‑on development, works independently and can contribute quickly with minimal technical supervision.

Key Responsibilities:

• Design and develop electrical and electronic hardware, with a focus on power circuits and DC-DC converters.
• Perform circuit design calculations, topology selection, component sizing and schematic development.
• Manage PCB development, including schematic capture, layout design or review, prototype bring-up and debugging.
• Develop power distribution, voltage regulation and protection circuits, considering efficiency, electrical loads and thermal performance.
• Conduct hands‑on testing, troubleshooting and validation of PCBs and power electronic assemblies.
• Develop test procedures and acceptance criteria to verify hardware performance under normal operating, transient and fault conditions.
• Investigate hardware failures, identify root causes and implement design improvements.
• Address EMC, power integrity, reliability, manufacturability and testability requirements.
• Work with system, software, mechanical, manufacturing and test teams on hardware integration.
• Maintain schematics, bills of materials, design calculations, test reports and release documentation.
• Participate in design reviews, risk assessments and relevant FMEA/FMEDA activities.

Requirements:

• Degree in Electrical Engineering, Electronic Engineering or a related discipline.
• At least 3 years of relevant electrical or electronic hardware product development experience.
• Strong hands‑on experience in PCB design, prototype bring-up, testing and troubleshooting.
• Practical experience in power circuit design, including circuit calculations, component selection and hardware validation.
• Direct experience in DC‑DC converter design, development and testing.
• Good understanding of analogue circuits, switching power supplies, power semiconductors, magnetics and voltage/current sensing.
• Proficiency with schematic capture and PCB design tools.
• Practical experience using oscilloscopes, multimeters, bench power supplies and electronic loads.
• Ability to independently manage hardware development from requirements through design validation.
• Strong analytical, problem‑solving and technical communication skills.

Added Advantages:

• Experience with battery‑powered equipment or systems, including 48V systems.
• Exposure to electric vehicles, automotive electronics, robotics or industrial power electronics.
• Experience with EMC testing, electrical transients and hardware reliability testing.
• Familiarity with design for manufacturing, design for test and FMEA/FMEDA.
• Experience taking products from concept through industrialisation or mass production.
