Senior Product Engineer (Java)

Job description

Back-end Engineer - Path to Plus Team Tech-first. Ego-free. User-obsessed. Over one million Danes use Skatteguiden to understand and optimise their taxes. We automate tax tracking, surface deductions people didn't know they had, and give users the insights they need to make better financial decisions — all directly connected to the Danish tax authority. We're an independent company of around 50 people based in Copenhagen, with a 4.7-star rating and a simple mission: make financial insight accessible to everyone, not just those who can afford an accountant. About the role Path to Plus is the engine that converts users into paying members and keeps them there. As a Backend Engineer on this team, you'll be primarily building and shipping features as part of a cross-functional product team, with an active pipeline and direct commercial impact. Alongside that, there's real work to be done in truly owning the services we're responsible for. Improving the codebase is part of the job, and engineers here have a genuine say in how that gets prioritised. You'll be joining a cross-functional team of software engineers, a product manager, a designer, and a data engineer. What you'll do Collaborate closely with product, design, data, and frontend to ship features end-to-end. Share ownership of backend services that power the membership and conversion funnel, as part of a team that takes build it, own it, operate it seriously. These are production systems with real users and real revenue attached. Build and maintain integrations with external services — think government data sources, mapping services, and user communication tools. Ship stock trading tax support — one of our most concrete upcoming projects, adding tax calculation support for stocks with multi-broker architecture on the horizon. You'll be part of designing and building that. Contribute to our move to Azure. We're migrating our systems and applications in the coming months, and cloud architecture thinking will be an active part of the role. Ensure observability of critical business flows. You'll help us catch issues before users do. You work with tech debt deliberately. We believe tech debt belongs on the roadmap, not hidden under it. You'll help identify, prioritise, and plan for it alongside the team. Who we're looking for You're a backend engineer with solid production experience who takes reliability and code quality seriously. You're comfortable working in an established codebase, able to move fast without cutting corners, and you understand that the systems you work on affect the business directly. You're someone who can look at a codebase, understand its strengths and weak spots, and work constructively with engineering leadership to make it better over time — without needing a perfect plan before you start. You operate with a build it, own it, run it mindset. We work that way, and we're actively investing in the observability and tooling that make it meaningful in practice. Must-have Solid experience with Java, JUnit, and Spring Boot. This is your expertise. Working knowledge of RabbitMQ or a comparable message broker. Familiarity with MySQL and relational data modelling. Comfortable working in established codebases with real production traffic. You know how to move carefully when it matters. Genuine enthusiasm for AI. You use AI tools daily in your own work and are always looking for new ways to apply them. This is an engineering-wide expectation at Skatteguiden, not a nice-to-have. Nice-to-have Experience with Kubernetes, Argo, GitHub Actions, and Grafana. Experience operating services in Azure (or another cloud environment) — understanding how your code runs in production, optimising resources, and thinking about cost without needing to own the infrastructure. Prior work in a product-led engineering organisation. Ways of working Technical skills matter, but so does how you work. We're looking for someone who is independent and proactive — you take ownership rather than waiting to be directed. You care about leaving code better than you found it, and you're realistic about how to make that happen in a production codebase. You work well with engineering leadership — not as a follower, but as a collaborator who contributes to the plan. You take the work seriously without taking yourself too seriously. Why join us Real responsibility from day one. You're joining a team with a full pipeline and a clear commercial mission — your work will have a visible impact quickly. Concrete, meaningful projects. Stock tax support and multi-broker architecture are live work, not hypothetical roadmap items. A company serious about engineering quality. We're actively investing in elevating engineering practices across the organisation. You'll be part of that, not just a passenger. Solid company. Independent, profitable, growing. No VC pressure, no bloated roadmap. Just a clear mission and a team that cares. Good people. We take the work seriously without taking ourselves too seriously. The culture is professional, informal, and genuinely collaborative. Room to grow. The scope of the work and the team's ambitions mean there's real room to step up. Practical details Location: Copenhagen. We're an office-first company, and it's a deliberate choice. We're moving fast, we have big ambitions, and we genuinely believe that being physically together is one of the things that makes that possible. Things move quicker when you can turn your chair and talk to someone. We're a five-minute walk from Rådhuspladsen, stocked with everything from fruit to fizzy drinks to afternoon snacks, and lunch is at Claus Meyer's canteen just across the street — proper food, not an afterthought. If you're putting in a long day, dinner is covered too. Start: As soon as possible. Salary: Competitive and based on your experience. Reporting to: Senior Engineering Manager. Our hiring process 1.
