Exponent Energy Hiring for Firmware Engineer – Charging Station and BMS at Bengaluru, Karnataka Full Time

You’ll be working with the product and engineering team.

This team runs on coffee with an infectious passion to build 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:
Fast 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 firmware engineer at Exponent you will work closely with hardware (it’s like a dance – you need both partners to be in sync with each other), understand baseline capabilities, and boost it 10X.

Responsibilities:
Define architecture.

Develop Algorithms.

Take code to production.

Experience in building charging + Battery (BMS) Algorithms.

Work closely with the hardware team, drive necessary hardware changes.

The ideal candidate requires:
Experience in taking firmware Design from concept to production

Good understanding of Microcontrollers and Microprocessors – GPIO’s, ADC, etc

Hand-on Experience in C and C++ programming

Expertise in developing communication protocols. Relevant protocols being I2C, Serial Peripheral Interface (SPI), USB, General-purpose input/output (GPIOs), Controller Area Network (CAN bus)

Experience with Model-based development is an added advantage

Hands-on experience in working with hardware products

Should have experience in working and setting up HIL and SIL Test rigs

We are looking for builders with a certain mindset: Build. Fail. Learn. Repeat.

What matters less:
Years of experience

Formal qualification

What matters more:
Quality of work

Approach towards problem-solving

Dissatisfaction towards mediocre work

Resilient attitude to bounce back after failing
