We're looking for a Senior Product Builder who wants to own product problems, not just engineering tasks.

You'll work across the full lifecycle of B2B initiatives:

This is not a frontend or backend-specific role. Our main stack is Ruby on Rails and React, but we care more about strong engineering fundamentals, product judgment and the ability to work across the stack when needed.

You won't receive a perfectly specified backlog. You'll be expected to help create the work: understand merchants and the business, challenge assumptions, work through ambiguity and decide with the team what is worth building.

• Own product initiatives end-to-end, from problem understanding to outcome validation.

• Act as Champion for initiatives: gather context, define hypotheses and success criteria, shape the work and drive it forward.

• Work directly with merchants, business stakeholders, Product Design and other engineering teams when needed.

• Build and operate production software across backend and frontend.

• Make pragmatic product and technical decisions with incomplete information.

• Use data, feedback and experiments to decide whether to iterate, change direction or stop.

• Contribute to evolving Merchant Portal into a platform other B2B teams can build on.

• Use AI throughout your workflow, including exploration, implementation, testing, debugging and learning unfamiliar systems.

Learn the B2B domain, Merchant Portal, codebase and current initiatives. Shadow a Champion, meet key stakeholders and start contributing.

Own a small initiative with support from the team, from understanding the problem to shipping it.

Act as Champion for an initiative: frame the problem, define the hypothesis and success criteria, ship a solution and check the outcome.
