Senior Fullstack Developer

Help build the platform that golf venues around the world run their business on. We are looking for a Senior Full Stack Developer to join the team behind Trackman Bookings & Payments, a multi-tenant SaaS platform covering everything from course and simulator bookings to memberships, pricing, and payments, both online and in person. This is a role for someone who enjoys working across the whole stack and likes getting deep into a genuinely complex domain.

What you'll do

• Build features end to end, from the booking and checkout flows players use to the back-office tools venue staff work in every day. That means working across a Next.js /React frontend, a Node.js backend, and the MySQL data model underneath.

• Work in a large, mature product that we are actively modernising, including an ongoing migration to TypeScript. You'll take pieces of that work and carry them through alongside feature delivery.

• Help raise our testing bar. Automated coverage is limited today, and we want it to grow with the code we touch.

• Work closely with UI/UX on how features look and behave, and with Product and QA on scope, edge cases, and quality.

• Contribute to code reviews and technical discussions, and help shape how the team solves problems.

What you bring

• 4+ years of professional experience building and maintaining production web applications. You might be early in a senior role today, or ready to take that step.

• Strong commercial experience with JavaScript and TypeScript on both sides of the stack: React (ideally Next.js) and Node.js.

• Comfort working in a large existing codebase. You enjoy improving code you didn't write, and you're as willing to work in older JavaScript as in new TypeScript.

• A good grasp of REST APIs and relational data modelling.

• A pragmatic approach to testing and CI/CD.

• Good communication and collaboration skills, and the ability to explain technical choices to non-engineering colleagues.

You don't need to arrive with a modernisation master plan. We have a direction. We're looking for someone who will take a piece of it, make good decisions in the detail.

Nice to have

• Experience with payment platforms or e-commerce / in-person payment flows (how gateways, acquirers, and schemes fit together), or with financial back-office concerns such as refunds, payouts, reconciliation, or reporting.

• Experience building or operating multi-tenant SaaS.

• Experience with Strapi, or another convention-heavy Node.js backend framework.

• Experience with Redux and RTK Query at scale, or with migrating legacy frontend state management.

• An interest in golf or sports technology.

The Office  

We are located at DTU Science Park in Hørsholm. We take great pride in the state-of-art building we have designed! The office features bright meeting rooms, coffee areas to catch up with colleagues, a large testing arena with simulators available for employees and a fitness center, everything surrounded by a beautiful forest and respecting the environment. We made sure to utilize the newest technologies to be energy efficient and be mindful of ventilation and sound propagation. The cherry on top is our canteen: with an indoor and outdoor area to enjoy the fresh food prepared by our own kitchen staff.
