Hardware Design Engineer - Power Electronics

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:

At Exponent, we unlocked 15-minute rapid charging of a Battery pack as a result of our e^pump (Charging Station) and e^pack (Battery) working together. Power Electronics is an integral part of both these systems. Everything on the Hardware Side from Architecture Design, Component Selection, Schematic, Layout, and DFX impacts the 15-minute rapid charging behavior.

We are looking for rockstar Power Electronics Engineers to work with us on our Flexible Energy Stack.

To rapid charge anything (2-wheeler to a multi-axle platform) in flat 15 mins, we need to fulfill multiple requirements: 10X accurate voltage sensing, 10X faster cell balancing, scales across voltage platforms (40-800V), CAN sense and handle upwards of 600A and has enough intelligence to manage 100’s of cells and Multiple Chargers in parallel

This needs impeccable hardware design skills and a deeply integrated firmware experience.

Responsibilities:

Define the right architecture (Question any existing architecture)

• Get. Set. Production.
• Block-diagram to schematics to layouts to characterizing it to testing it to working with our manufacturing partner to scale it – you will own this.
• Timeline vs. Quality vs. Cost.
• Choose the right components at the right price point to meet the specifications and make smart trade-offs.

The ideal candidate requires:

• Experienced in taking hardware design from concept to production
• Understanding of DFX (DFA, DFM, DFT etc.)
• Good understanding of Power Electronic fundamentals (eg: Voltage across a capacitor can’t change instantaneously)
• Deep understanding of Mosfets, Diodes, Capacitors, and Inductors
• Expertise in AC-DC, DC-DC Converter design
• Expertise in Schematic Design and Simulation study
• Thermal analysis, Tolerance analysis, Stress analysis & cost analysis
• EMI/EMC experience is added advantage

What matters:

• Quality of work
• Approach towards problem-solving
• Dissatisfaction with 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 150+ 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.
