## Description

You will take ownership of the design of high-voltage battery management electronics used across Fuse’s energy storage and distributed energy platforms. You will work end-to-end from early concept and requirements definition through schematic and PCB layout, validation and deployment into production and fielded systems.

Responsibilities:

- Design, prototype, build and test high-voltage battery management electronics for Fuse Energy’s stationary storage and grid-connected systems
- Own end-to-end PCBA development, including requirements definition, schematic capture, PCB layout, design reviews and design for manufacturability
- Develop automated validation setups and test firmware/software to ensure comprehensive functional, performance and safety coverage of BMS designs
- Support the transition of designs from prototype to production, including supplier engagement, bring-up and production test strategy
- Collaborate with firmware and software engineers to define hardware–software interfaces, diagnostics and safety mechanisms
- Work closely with mechanical and systems engineers to ensure electrical designs are optimised for thermal performance, isolation and environmental constraints
- Perform detailed failure analysis and root-cause investigations on PCBAs and systems in both lab and field environments
- Evaluate, select and integrate battery monitoring ICs, microcontrollers, isolation components and communication interfaces suitable for high-voltage applications
- Continuously improve designs to optimise reliability, component availability and BOM cost as systems scale

Requirements:

- Bachelor’s degree in Electrical or Electronic Engineering or equivalent practical experience
- At least 5 years of hands-on industry experience in analog and digital electronics design
- Strong fundamentals in circuit analysis, simulation and design trade-off evaluation
- Proven experience designing and debugging complex PCBAs with excellent failure analysis and troubleshooting skills
- Solid proficiency in Python for test automation, validation and data analysis
- Experience in one or more of the following domains: battery management systems, power electronics, high-voltage systems, microcontrollers or high-speed digital interfaces
- Familiarity with communication interfaces commonly used in BMS and energy systems (e.g. CAN, RS485, Ethernet, SPI, I²C)
- Experience with Altium Designer and circuit simulation tools such as LTSpice
- Exposure to mechanical CAD tools (e.g. Fusion 360, SolidWorks or similar), rapid prototyping and close collaboration with mechanical design

Benefits:

- Competitive salary and an equity sign-on bonus
- Biannual bonus scheme
- Fully expensed tech to match your needs
- Paid annual leave
- Breakfast and dinner allowance for office based employees
