Job description

You’ll be working with theengineering and validationteam.

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
