Synop is building the platform that is accelerating the electrification of commercial fleets. Founded in 2021, we've quickly become one of the leading commercial EV platforms, helping customers with their day-to-day operations and putting them in a position to succeed. We work with fleets, utilities, aggregators, and operators to deliver reliable, cost-optimized charging, energy management, fleet services, and billing solutions — so that the electric transition is not just possible, but profitable.

About You

You are a backend engineer who knows the best way to design something, but also enjoys taking the scrappier approach when it makes sense. At the end of the day, you are excited that you have solved a problem to provide a better experience for a customer, and to put a product out in the world that makes a real difference toward sustainability.

You like to engage and collaborate with colleagues across the team from Engineering to Customer Support to Product and to Business in order to understand the whole business perspective and know how your work fits into the bigger picture. You also might already love electric trucks, or at least be open to seeing what they are all about!
