🏢 About Charge Point

ChargePoint is at the forefront of the EV revolution, operating the world's largest open charging network. With a mission to make e-mobility a global reality, you'll join a team driving the transition to electric vehicles, which are projected to be 30% of new sales by 2025. This is a unique opportunity to shape the infrastructure for a trillion-dollar market.

About This Role

As a Senior Software Engineer on the Driver Service team, you'll design and build scalable backend services that power the driver experience for millions of EV users. Your work will directly impact how drivers find, access, and pay for charging, making electric travel seamless and reliable. This role is critical to enabling the widespread adoption of EVs.

💡 A Day in the Life

You'll start by reviewing system health dashboards and any alerts from the previous night. Then, you'll join a standup with your team to discuss progress on building a new charging session management service. The afternoon might involve coding a new API endpoint, reviewing a peer's pull request, and collaborating with product managers on requirements for a driver-facing feature.
