Senior Software Engineer - Backend, OE Engineering

We’re looking for a talented software engineer to help solve exciting challenges for our sustainability-focused energy retailer client.

Our team members are passionate about technology and making a positive impact on the planet. They’re self-motivated problem-solvers who love taking initiative and helping others grow while delivering great results for customers and teammates.

We value people who are adaptable, collaborative, and thoughtful decision-makers. They embrace change, create an inclusive environment where everyone belongs, and stay calm under pressure while always being ready to help.

About the Team

We’re on a mission to create intuitive, engaging, and scalable digital experiences for consumers - from customer signup journeys to campaign integrations and beyond, our projects are as diverse as our ideas, and we always keep users front and center.

Our team’s still growing, which means you’ll be part of shaping how we work. We move fast, learn quickly, and care deeply about clean code, smart testing, and good monitoring. We believe great communication is key: we lean on quick face-to-face chats or huddles for fast-moving topics, and use Slack, Asana, and other async tools to keep things running smoothly in the background.

We’re transparent, collaborative, and not afraid of a bit of trial-and-error. Expect regular reviews, lots of learning, and plenty of chances to make your mark.
