Senior Software Engineer role focused on payments and finance systems at a Series A AI startup enhancing recreation.

Responsibilities

  • This is not a seat-filling role. We're a Series A company in scaling mode, processing more transactions every day, and the systems that handle our partners' money need someone who owns them.
  • That's this role. Every dollar that flows through Rec — a parent paying for summer camp, a department collecting membership dues, a parks department invoicing a facility rental — runs through the systems you'll build. You'll own our Stripe integration, the financial data model underneath it, and the accounting and reporting tools our partners use to run their business. You'll make sure the money moves correctly, the books reconcile, and the reports our partners rely on are accurate down to the cent.
  • You'll still ship across the broader platform when the work calls for it, but the primary job is owning payments and finance. Our partners trust us with their revenue. That trust is everything.

Requirements

  • 5+ years of experience building software in collaborative environments.
  • You're fired up by the mission.
  • AI fluency is non-negotiable.
  • You ship with quality. Every customer transaction matters to us: a missed swim lesson registration, a double-booked court, a failed payment. Reliability is the baseline.
  • Product judgment is part of the job.
  • You thrive in ambiguity.
  • You work like a partner, not just a coder.
  • You communicate clearly, candidly, and constructively.

Conditions

  • Compensation: $150,000–$200,000 base + meaningful equity
  • Benefits: Flexible PTO, top-tier health/dental/vision, 401(k).
  • Work location: San Francisco — in-office most days at our downtown SF office.

Other

  • Think about the last time you tried to book a tennis court. Or sign your kid up for a swim lesson. Or find an open rec league that actually fits your schedule. You probably ended up on a website that looked like it was built in 2003 — or god forbid, filled out a piece of paper.
  • $3T is spent on recreation globally, and it's built on a completely fragmented system that's largely untouched by technology.
  • At Rec ( recreation.ai ), we're using AI to change that — reimagining how the world plays, participates in community, and gets active. Our vision is simple: more recreation for everyone. We sit at a rare intersection — a consumer product loved by everyday players and an enterprise platform trusted by the organizations that power recreation.
  • We're a small team with firepower. Our founders were among the first few hundred at Uber, then led teams at The Athletic and MasterClass. The rest of the team combines builders from Google, Microsoft, Strava, Hipcamp, and Airbnb.
  • People join Rec for two reasons: you want to build AI that gets people back in the real world, and you want to work with really smart people.
  • Own our Stripe integration and the systems that handle every financial transaction on the platform, from one-time bookings to recurring memberships to payouts and payment plans.
  • Build and evolve the accounting and reporting tools our partners use to run their businesses, including financial reports, reconciliation, and exports to downstream accounting systems.
  • Model the financial data layer carefully. Money is unforgiving of bad schemas.
  • Partner with Product, Design, and Partner Success to understand what our partners actually need from their financial tooling, and build for the real workflows.
  • Make sure payment failures, refunds, chargebacks, disputes, and edge cases are handled cleanly, reliably, and observably.
  • Help us stay compliant as we grow (PCI, SOC 2, tax reporting, and whatever else the business requires).
  • Use AI tools fluently across your workflow, from drafting Stripe webhook handlers to debugging reconciliation issues to analyzing transaction data.
  • Contribute to the broader platform when the work touches payments or finance.
  • Frontend: Next.js (hosted on Vercel), React, TypeScript
  • Backend: Node.js, Koa, Objection.js, PostgreSQL
  • Infra & Ops: AWS, Temporal, Twilio
  • AI & Tooling: Claude Code, Cursor, or equivalent — mandatory.
  • Be Relentless. Move fast. Own it. Ship real value early and often.
  • Win Together. Speak up, go beyond the boundaries of your role. That's how we win.
  • Take Pride. Treat this like it's yours — because it is.
