Mechanical Design Engineer

Open 18d

You’ll be working with the 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.

Role Description

We are looking for an experienced Mechanical Design Engineer with 4 to 6 years' to develop sheet metal components (e.g., enclosures, electrical panels) and optimize packaging for the e^pump. You will drive structural and thermal designs that are efficient, cost-effective, and manufacturable while meeting safety and performance requirements.

Responsibilities:

  • Designing for weight, volume, thermal performance, and IP sealing while ensuring serviceability and manufacturability (DFM/DFA).
  • Performing conceptual designs, theoretical calculations, and tolerance stack analyses.
  • Developing and executing test plans to validate subsystems and full product performance.
  • Conducting root cause analyses (RCAs) for issues during testing and field deployment.
  • Collaborating with manufacturers, assembly teams, and mold designers to refine designs based on feedback.
  • Documenting the product development cycle from concept to production stabilization (FMEA, DFX, DVP, inspection plans, etc.).

What You Bring:

  • Expertise in structural design, thermal systems, and electro-mechanical packaging.
  • Strong understanding of fluid systems, heat transfer (conductive/convective), and refrigeration basics.
  • Hands-on experience with mechanical assembly, IP sealing, and optimizing packaging for cost and performance.
  • Solid knowledge of materials (Metals, Plastics, Composites, Elastomers) and their applications.
  • Proven experience in taking a product from concept to production, backed by strong mathematical and analytical skills.

What matters:

  • 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.

What this application asks

workable

First name, Last name, Email, Phone, Address, Education, Experience, Resume

  • Have you engineered a mechanical subsystem — like a busbar, chassis, battery pack, or enclosure — that went into production? (Examples: Battery module housing, EV chassis, high-current busbars, thermal structures for electronics, etc.) What was the product? What was your exact role in the design? What trade-offs did you face between thermal, structural, vibration, IP sealing, and manufacturability? How did you validate the design? (Calculations, simulation, bench tests, etc.) Blanks or generic, or AI-generated responses will be rejected written answer
  • If no, Have you contributed to prototyping or concept engineering of an electromechanical product (e.g., EV battery pack, charging station, thermal system, structural housing)? What performance aspects did you focus on: thermal, vibration, strength, sealing? How did you make those decisions, and what were the trade-offs? Blanks or generic, or AI-generated responses will be rejected written answer
  • How many years of experience do you have since graduating? This role is applicable for folks with 4 to 6 years, outside of projects in colleges. written answer
