Full Stack Software Engineer, Core Experience

About the Role

When the grid goes down, Base members often don’t even notice: their lights stay on, and their bills go down. That’s what a modern power company feels like, and this team builds the platform and product that delivers it.

Getting a member to that moment means coordinating a physical installation: home photos, city permits, utility approval, an install crew, and a battery coming online, each on its own system and timeline and variation for each utility we enter. We're already operating in three states, with plans to expand into several more in the coming months.

Our goal is one platform where launching a new market is mostly configuration, so we can scale efficiently and give every member a consistently great experience.

The Core Experience team owns that journey in software, from the first website visit to the app that shows backup and savings in real time. We’re hiring a full stack engineer to build the platform that powers our expansion and the product our members love.

What You’ll Do

• Own the member journey end to end, from the first website visit to the moment a member checks the app during an outage

• Build the discovery and checkout experience: accurate plans and pricing for every address, across products and markets

• Build the activation experience: photo submission, a live status tracker and internal tools that keep members, our operators, utilities, and install crews on the same page

• Turn live battery telemetry into clear in-app experiences, including real-time outage status, bills that explain themselves and battery performance

• Ship across the full stack (database, API and UI) and define the metrics that tell us whether it worked

• Partner with design, Growth, deployments and member support, and use support data to build self-serve into the product

What You’ll Bring

• 2+ years of experience building production software in product or full-stack engineering roles

• Strong experience designing system architecture for complex web applications

• Track record of owning products or platforms from concept through launch and iteration

• Strong product judgment and a track record of turning ambiguous ideas into shipped, useful products.

• Ability to work across the stack and collaborate closely with XFN teams

• Ready to work with intensity and urgency, and to hold a high bar for your own output.

Our Values

• First Principles Thinking: Question assumptions. Principles > rules.
