About the role

We’re hiring a founding Senior Backend Engineer to help us design, develop, and ship robust backend systems that deliver exceptional value to our members.

Stay current with the latest advancements in backend technologies and cloud infrastructure, and integrate new technologies and methodologies as appropriate

Level up a growing engineering team by reviewing code and designs of teammates and providing constructive feedback to maintain high quality

About you

You’re passionate about building robust systems. You have a deep understanding of backend architecture, API design, and database management, and you’re excited to build systems that scale with our growing member base

You’re excited to be a founding engineer at an early-stage startup. This means that there’s a lot of systems and structure yet to be put in place, and you’ll play an active role in building and shaping those alongside our company culture

You’re excited to build. You embrace the challenges and growth that come with joining an early-stage company, thriving in a fast-moving, evolving environment

You think and act like an owner. You take a long-term view, make decisions with care, and are eager to take initiative and responsibility with good judgment

You roll up your sleeves. You find satisfaction in taking action, solving problems, and learning quickly, rather than delegating or managing from the sidelines

You’re mission-driven and adaptable. You understand the stakes of a startup, focus on what matters most, and dedicate yourself to building for long-term success

You thrive on collaboration and problem-solving. You work best in an in-person culture, feeding off shared energy, brainstorming, and engaging with others daily
