Job summary

Exponent simplifies energy for EVs. You will join the engineering and validation team to test firmware for the E-pack, E-pump ecosystem, enabling a 15-minute charge experience.

As a test engineer you will emulate firmware, develop test cases, perform regression testing, and analyze results using Python on Raspberry Pi and other GP systems.

The role requires 2+ years firmware testing, Linux/C/C++, and MCU programming (STM/TI) with CAN/SPI/I2C knowledge.

Qualifications

• 2+ years of experience firmware testing.
• Hands-on Raspberry Pi and Python experience.
• Knowledge of Linux, C/C++ and MCU programming.

Responsibilities

• Emulated testing of firmware of various EEPL components
• Develop test cases for testing the logic and timing of revisions of firmware.
• Regression testing based on change content
• Python coding for emulation of signals
• Automatic test result analysis by test firmware
• Timely completion of testing activities
• Raising bugs and following up in teams for closure
• Presenting the metrics on testing.
• Use Raspberry PI like general purpose systems as test tools.

Job description

You’ll be working with the engineering and validation 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:

We’ve cracked rapid charging repeatably. The e^pack, e^pump and e^plug work together to deliver a 15 minute charge experience.

As test engineer you will execute the testing of battery or BMS or pump, or connector or integration test of these individual components as an ecosystem.

Responsibilities:

• Emulated testing of firmware of various EEPL components
• Develop test cases for testing the logic and timing of revisions of firmware.
• Regression testing based on change content
• Python coding for emulation of signals
• Automatic test result analysis by test firmware
• Timely completion of testing activities
• Raising bugs and following up in teams for closure
• Presenting the metrics on testing.
• Use Raspberry PI like general purpose systems as test tools.

The ideal candidate requires:

• 2+ years of experience firmware testing
• Raspberry - Pi and python hands on experience
• Linux, C / C++ knowledge
• STM and TI micro controller programming
• Knowledge of CAN, SPI , I2C, RS485 communication
• Capability to develop GUI for testing
• Methodological approach towards testing
• Capability to handle large no. of test cases in comprehensible fashion.
• Knowledge of BMS / CMS
• Capability to work with Arduino, STM, TI development boards.

What matters more:

• Discipline
• Quality of work
• Approach towards problem-solving
• Dissatisfaction towards mediocre work
• Resilient attitude to bounce back after failing

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 have a ton of EV experience and are currently looking for more builders to join one of the best EV teams in India to build & scale Exponent.
