Senior Hardware Design Engineer

Maxwell Energy Systems is building the next generation of intelligent electronics for electric mobility. Our engineering teams design and develop products across Battery Management Systems (BMS), EV Chargers, Motor Controllers, DC-DC Converters and other automotive electronic systems for leading EV manufacturers in India and global markets.

We are looking for a Senior Hardware Design Engineer who can take complete ownership of complex electronic hardware from architecture and component selection through circuit design, PCB development, validation and production.

This is a hands-on engineering role for someone who enjoys solving challenging hardware problems and wants to see their designs deployed in real products at scale.

What you'll do:

Own the end-to-end hardware development of automotive electronic control boards from requirements, architecture and component selection to schematic, PCB, prototype, validation and production
Design and develop analog, digital and power electronics for BMS, EV chargers, motor controllers, DC-DC converters and other high-power electronic systems
Perform detailed circuit analysis, simulation, component selection, design calculations and design reviews to ensure robust product performance
Design and review high-current/high-voltage power stages, including MOSFETs, IGBTs, diodes, gate drivers and associated protection circuitry
Develop robust MCU/DSP-based control electronics, including signal conditioning, sensing, communication interfaces and board-level power supplies
Lead PCB architecture and layout decisions including component placement, current-loop optimization, power/signal partitioning, thermal considerations, creepage/clearance, parasitic inductance/capacitance and EMC performance
Drive hardware designs through EVT/DVT/PVT, validation, debugging and production release, working closely with Firmware, Systems, Mechanical, Test, Quality and Manufacturing teams
Design for cost, manufacturability, reliability and scalability, including products manufactured at 100k+ unit volumes
Lead hardware troubleshooting and root-cause analysis of issues observed during development, validation and field deployment
Ensure compliance with applicable automotive electrical, EMC/EMI, environmental, reliability, safety and functional-safety requirements
Work closely with the BMS Hardware/Firmware teams to develop and validate production and engineering test equipment
Mentor junior hardware engineers and contribute to improving Maxwell's hardware design practices, reviews, component selection and engineering processes

Must Have Requirements:

5+ years of hands-on experience in electronics hardware/product development within a design and manufacturing environment
Strong fundamentals in analog, digital and power electronics
Proven experience taking electronic products from concept → schematic → PCB → prototype → validation → production
Strong experience with Altium Designer for schematic capture and PCB design/review
Experience with MOSFET/IGBT/diode selection, gate-driver design, protection circuits and high-current power electronics
Experience with MCUs/DSPs and their peripheral circuitry, including sensing, signal conditioning, communication interfaces and power supplies
Strong understanding of PCB layout for power integrity, signal integrity, thermal performance and EMI/EMC
Experience with circuit simulation and design-analysis tools
Understanding of DFM/DFA, component derating, reliability and design-for-cost principles
Ability to independently debug complex hardware using laboratory equipment such as oscilloscopes, electronic loads, power supplies, multimeters and other diagnostic equipment
Good understanding of hardware validation and product qualification methodologies
Strong written and verbal English communication skills, with the ability to collaborate effectively with global engineering teams
Bachelor's or Master's degree in Electrical/Electronics Engineering (EEE/ECE) or equivalent practical experience

Nice to Have:

Experience with Li-ion batteries, BMS, EV chargers, motor controllers, DC-DC converters or other automotive power electronics
Experience working on automotive products and production-intent hardware
Familiarity with Functional Safety (FuSa), ASPICE and automotive hardware development processes
Experience with EMI/EMC testing and troubleshooting
Experience with high-voltage isolation, insulation coordination, creepage/clearance and safety-critical hardware
Experience taking products through DV/PV, certification and mass production
Experience working with 100k+ annual production volumes

Why Maxwell?

At Maxwell, you will work on real EV products that go into the hands of customers, rather than prototype-only electronics.

You will get the opportunity to work across the complete hardware development lifecycle, solve challenging problems in power electronics and automotive systems, and work closely with a multidisciplinary engineering team.

If you are an engineer who enjoys owning difficult hardware problems from first principles all the way to production, we'd like to hear from you.

Apply and build the future of electric mobility with Maxwell Energy.
