Full Stack Software Engineer, Growth

About the Role

Base is a power company that installs a battery at your home. Most homeowners have never heard of that, and most don’t like their electric utility. That’s our growth challenge. A homeowner has to understand a new kind of product, trust a company they just met, and finish an onboarding journey to get a battery installed. Every step is a chance to earn them or lose them.

Base is growing fast, in Texas and nationwide. We’re hiring a full stack engineer to own the products and systems that drive acquisition (getting found), activation (going from sign-up to a working battery) and retention (staying with Base and telling neighbors). That means 1) experimenting on and scaling our existing product, and 2) building new growth products and infrastructure from scratch.

Judgment is a core part of the job: knowing where to create leverage, which friction matters and which problems are worth solving. We care about conversion, but never at the expense of clarity, trust or the long-term quality of the brand.

This is a lean team that moves fast and gives you real ownership. We’re not looking for someone to execute a handed-down roadmap. We want someone who finds the opportunities, works from first principles and ships.

What You’ll Do

• Turn ideas into shipped tests across the member journey, from redesigned sign-up flows to paid ads campaigns and referral experiences

• Write the code, read the results and decide what to test next

• Own the products and systems that drive acquisition, activation and retention

• Build the growth infrastructure that makes experimentation fast and trustworthy, including the data pipeline behind it

• Use judgment on where to create leverage and which problems are worth solving, optimizing for conversion without sacrificing clarity or trust

• Find opportunities and work from first principles rather than executing a handed-down roadmap

What You’ll Bring

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

• Strong frontend and full-stack engineering skills, with comfort across modern web applications, APIs, data models, and stateful user experiences.

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

• Experience building in 0-to-1 or fast-moving environments where user needs, product shape, and success metrics are still evolving.

• Experience using product analytics, experimentation, and data to guide decisions

• 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.
