Firmware Engineer

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 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 Junior 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 Develop FW - 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 The ideal candidate requires Hands-on experience and proven excellence in product firmware development for microcontrollers with 1 - 3 yrs of relevant experience Zeal to understand products and find better solutions for crucial problems Strong design development and debugging skills in embedded C C along with bare-metal RTOS and some scripting and automation Python Shell Strong knowledge of embedded hardware ARM and DSP microcontrollers ADCs GPIOs and communication protocols CAN UART I2C SPI etc Experience on understanding schematics datasheet s and manuals Have an understanding of working with cross-functional teams in an Agile environment product lifecycle for firmware SDLC and version control Git Understanding of power electronics products like BMS Charger and Motor controllers is a big plus We are looking for builders with a certain mindset Build Fail Learn Repeat What matters more Quality of work Approach towards problem-solving Dissatisfaction towards mediocre work Resilient attitude to bounce back after failing Up to 2 years of experience About Us Exponent simplifies energy for EVs Co-founded by Arun Vinayak Ather Energy s Founding Partner Former Chief Product Officer and Sanjay Byalal Former hardware strategic sourcing and cell strategy lead Ather and Former Supply Chain Lead HUL Exponent focuses on solving two sides of the energy problem by building the e pump charging station and e pack battery pack which together unlock 15-min rapid charging The 200-strong team of passionate builders has a ton of EV experience and is currently looking for more builders to join one of the best EV teams in India to build scale Exponent
