Job description

About Exponent

Exponent is on a mission to redefine energy for electric vehicles. We're building deep tech from India, for the world — engineering batteries, charging networks, and the technologies (e^pump and e^pack) that enable 15-minute rapid charging for EVs at scale. We're now a team of 200+ passionate engineers, designers, and operators building one of India's fastest-growing EV energy companies.

We move fast. We ship hardware and software. We obsess over customer satisfaction. And we're building the foundation of how electric mobility gets powered — in India, and eventually the world.

Why This Role Matters

You're here to build all of Exponent's customer-facing software — the external mobile apps and websites that thousands of EV drivers and customers use, and the internal optimization tools that power our operations behind the scenes.

You'll be involved across largely every software product built at Exponent. This is a team that adopts the latest tech, moves fast, and ships constantly — and you'll get to learn and grow at that pace.

What You'll Do

You'll work across the full spectrum of Exponent's software — building, shipping, and improving:

• External-facing mobile apps (React Native) for drivers and customers — discovery of chargers, payments, tracking, smart optimisation of charging network utilisation, and everything in between.
• External-facing websites (React) for customers, partners, and the broader public.
• Internal optimization tools that help our operations, network, and business teams run efficiently — monitoring, analytics, and workflow automation.
• Backend services in Python that power all of the above — APIs, business logic, data pipelines, integrations.
• Cross-team collaboration with product, design, hardware, firmware, and operations teams to deliver end‑to‑end features.
• Production excellence — debugging, monitoring, optimizing — because reliability and speed are non‑negotiable.

You won't be siloed. You'll touch a wide range of products, work with the latest tools and frameworks, and have real ownership over what you ship.

What We're Looking For

We care more about how you think and how you ship than the exact lines on your resume.

The mindset:

• Builder's intent — you actually want to build things. You enjoy taking an idea, breaking it down, and turning it into working software.
• Structured problem‑solving — you can take a messy, open‑ended problem, brainstorm approaches, break it into smaller pieces, and attack them one by one.
• Ownership — you take a project from spec to production and don't drop the ball halfway. You don't wait to be told what to do next.
• Curiosity & learning speed — you pick up new tools, frameworks, and domains quickly. The stack will evolve; you should enjoy that.

The basics:

• 1.5+ years of professional software development experience, with strong full‑stack exposure.
• Solid hands‑on experience building modern web and/or mobile applications — strong proficiency in Python, React, and React Native preferred, or equally strong fundamentals in a comparable modern stack.
• Strong grasp of backend services, RESTful APIs, and databases.

Your Career Growth

• Ownership: Small, high‑impact team where you own features end‑to‑end — design to deployment.
• Latest tech, fast pace: Work with modern frameworks and tools, and learn alongside a team that ships constantly.
• Decision‑making: Make technical and product calls that directly shape customer experience.
• Booming sector: Grow with one of the most transformative industries globally.
• Full‑stack exposure: Work across mobile apps, websites, internal tools, and cloud platforms.
• Impact at scale: Your code powers real products used by thousands of customers every day.

Our Philosophy: Break. Believe. Build.

• Break assumptions and conventions.
• Believe in the team, the process, and the potential of failures to drive innovation.
• Build swiftly and passionately, simplifying and elevating the customer experience.

Join Us

We're rebuilding how India (and the world) powers electric mobility — across batteries, charging, and everything in between. If you want your code to power the future of energy, we'd love to talk.
