Description
You’ll be working with the product and engineering team.
This team runs on coffee with an infectious passion for building products that have never been built before. Our Flexible Energy Stack consists of the e^pack (battery pack) and e^pump (charging station) which together unlock 15-minute rapid charging.

Our philosophy: Break. Believe. Build
Break stuff. Break assumptions. Break the thumb rule.
Believe in the team. Believe in the process. Believe through failures.
Build fast. Build passionately. Build to simplify.

What you will do:
Rapid charging a battery pack requires the charger and the battery to communicate with each other perfectly and work in sync. This is achieved when 3 things come together:
- Great battery pack design
- Reliable & accurate hardware
- Innovative & efficient firmware and algorithms (battery and charging algorithms)

Software and hardware are critical to the efficient working of a well-designed battery pack. At Exponent, we take our software very seriously, and to complement it,



we build our own hardware to the highest standards – fully in-house.

As a senior Firmware Engineer, you will be building the safe, reliable, and modular FW tech stack responsible for charging thousands of vehicles within 15 minutes.
You will work closely with hardware (it’s like a dance – you need both partners to be in sync with each other), utilizing data to build Algos to boost the Battery and Charger performance

Responsibilities:
- Define FW architecture - select HW, device optimal HAL layers, enable features (OTA, UDS, et al), and define FW blocks
- Develop Algorithms - design application layer with state machines and algorithms to process data and compute critical parameters like Sox
- Take code to production - Design, development, validation, and deployment in the field; debugging and diagnostic SOPs, service manual
- Reliability - Understanding and implementation of safety and reliability of firmware, FMEA, and Code and Risk reviews
