Software Developer – Ruby on Rails in Belfast

We're hiring experienced Ruby on Rails developers to work directly with our CTO, shaping the architecture, the culture, and the future of engineering at TeamFeePay. Every week, thousands of sports clubs wrestle with spreadsheets, bank transfers, and chasing payments. We're ending that. TeamFeePay is building the platform that lets clubs of any size — from a grassroots youth football club to a multi‑team rugby organisation — manage memberships and payments without the headache. We're growing fast, clubs worldwide are coming on board, and we need engineers who want to build something that matters.

Company Purpose
To help communities build sustainable grassroots football clubs by revolutionising club management, finance, governance, safeguarding and communication. We build people‑first technology that reduces admin, builds trust, and supports clubs to thrive — not just survive.

What You'd Actually Be Working On
Most of our clubs are run by volunteers — parents and coaches giving up their evenings and weekends. We've built a system that lets a club treasurer set up payment collection for hundreds of families across multiple age groups in minutes, replacing what used to be weeks of spreadsheets, WhatsApp messages, and awkward conversations at the sideline. Other things on the horizon include transforming our club onboarding into a streamlined self‑service experience, building smarter automation that takes even more admin off volunteers’ plates, and rearchitecting core systems to handle rapid international growth.

The Stack
Rails (our core), Hotwire (Stimulus + Turbo), Heroku for existing infrastructure, Kamal + Hetzner for new deployments. PostgreSQL. We keep things modern and pragmatic — no legacy baggage for the sake of it.

The Role
Build and ship, end to end. You'll own features from concept through to production — designing, coding, and deploying clean, maintainable Rails code that delivers real value to clubs and their members. Scale a platform under real pressure. As more clubs join globally, you'll solve the hard problems: performance at scale, data integrity, robust payment processing, and keeping everything rock‑solid as traffic grows. Shape the technical direction. This isn't a ticket factory. You'll contribute to architectural decisions, influence our tech stack, and set the engineering standards that future hires will follow. Work with AI as a force multiplier — seriously. We expect our developers to use AI tools as a core part of how they work.

Specifically, we're looking for engineers who:

• Use agentic coding tools like Claude Code, Cursor, or similar to plan, build, test, and ship features — not just autocomplete.
• Can direct AI agents through multi‑step workflows: breaking down requirements, generating code, writing and running tests, debugging, and iterating to production‑ready output.
• Leverage AI for code reviews, refactoring, test generation, and exploring architectural trade‑offs.
• Think critically about AI output — you know when to trust it, when to push back, and when to take a different approach entirely.
• Are excited about building internal tooling and workflows that make AI‑assisted development even more effective across the team.

As part of our process, we'll ask you to walk us through how you'd use AI tools to ship a feature end‑to‑end. We want to see your thinking, not just your prompts. Raise the bar for the team. Mentor junior developers, champion best practices, and help us build an engineering culture rooted in continuous learning and pragmatic excellence.

What we’re looking for

• At least 2 years building and maintaining large‑scale Rails applications and SaaS products.
• 2+ years of web application development experience.
• Demonstrated, hands‑on experience using AI coding tools in your daily workflow.
• Strong problem‑solving instincts and the ability to navigate ambiguity.
• Clear, effective communication — you can explain technical trade‑offs to both engineers and non‑technical stakeholders.
• Self‑motivated, ownership‑driven, and comfortable working autonomously in a remote team.

Nice‑to‑haves:

• Experience with Hotwire, Stimulus, and Turbo.
• Familiarity with payment processing systems (Stripe, Adyen, GoCardless, or similar).
• Experience with deployment tooling like Kamal, Docker, or Heroku pipelines.
• Background in building multi‑tenant SaaS platforms.
• Interest in sports (not required, but you’ll find yourself caring about club management more than you expected).

Why TeamFeePay

• Flexibility that’s real, not performative. Choose from office, hybrid, fully remote, 4‑day weeks, or reduced hours.
• Competitive, negotiable salary that reflects your experience and what you bring to the table.
• Outsized impact. At a scaling startup, every decision you make ripples across the product.
• Global reach. Your code powers clubs around the world.

Important: This role has remote options, but to keep collaboration smooth, you must reside within 2 hours of GMT. Ready to build something clubs actually love using? Apply now.
