Apply for this job We usually respond within two weeks up to 48,000 DKK/month gross (varies by seniority) About Monta Monta powers the EV charging ecosystem. With 300,000+ monthly users and millions of charge sessions every month, our platform accelerates the electrification of mobility. This is a fast-moving place. The problems are hard, the pace is quick, and the bar is high. If you like real ownership, figuring things out, and seeing the direct impact of your work, you’ll do well with us. AI is built into how we work. It helps us ship faster, make better decisions, and stay lean. Everyone at Monta is expected to use AI tools thoughtfully — and to find smart ways to use them to move the work forward. Our principles keep us grounded: Build Together & Finish, Sweat the Details, Customer First, and Aim for the Moon. The best part of Monta is the people — sharp, ambitious, and good to be around. You’ll be challenged, supported, and trusted to deliver. The Role We're looking for an Engineer to join our Financial Services team, the team responsible for every euro that flows through Monta's platform. This is a hands-on individual contributor role where you'll own delivery of meaningful pieces of our financial systems and grow your expertise in the domain, helping us scale reliably as we expand across Europe. Financial Services is at an inflection point. Our transaction volume is growing fast and already processes millions of euros each month. We're building the next generation of our financial infrastructure, including new billing models and compliance capabilities to support expansion into new EU markets. The problems are hard, the stakes are real, and the work matters. We need someone who takes ownership of what they build. You'll own medium-sized projects from design through to production, working independently within your team and delivering quality outcomes. You should also be someone who has embraced AI as a core part of how you work. We use Claude Code extensively across the Financial Services team for everything from writing and reviewing code to designing systems and exploring financial domain problems. We expect you to be an advanced AI user who actively finds new ways to leverage these tools to move faster and think better. This Is What You Will Achieve Help rebuild Monta's financial backbone. You'll contribute to the new invoicing system that every customer will use, owning meaningful slices of the new infrastructure. Power EU expansion. You'll build features within our compliance infrastructure (e-invoicing, fiscalization, VAT) that enables Monta to enter new European markets. Strengthen the money flow. You'll improve the reliability and scalability of payment processing, reconciliation, and withdrawal systems across a rapidly growing transaction volume. What You’ll Do Deliver core parts of the new invoice system. Build features within the new invoicing architecture that supports multiple billing models and financial flows, owning your slice end-to-end and contributing to design discussions. Build and scale compliance infrastructure. E-invoicing across European markets. Fiscalization integrations. A VAT engine that handles the complexity of cross-border EV charging. Improve payment flows from card to payout. Card payments, automated reconciliation, withdrawal reliability, and working capital management. Collaborate across Finance, Legal, Revenue Operations, and Product to deliver new billing and commercial models. You won't work in a silo. Build for systems that must be right. Every euro must be traceable from summary down to line item. You'll write code with auditability, correctness, and scale in mind, and contribute to design discussions for new components. Grow with the team. Contribute through code reviews, design discussions, and knowledge sharing, and help onboard new joiners as you grow into the domain. What We’re Looking For Solid backend engineering experience. You've built and shipped production systems and you write clean, maintainable code. Java/Kotlin preferred, but strong engineers from other stacks are welcome. Some exposure to financial systems is a plus. Billing, invoicing, payment processing, or similar domains where correctness matters — but we'll help you grow the depth. A sense of ownership. You take responsibility for what you ship, follow it through to production, and flag issues early rather than waiting to be asked. Comfortable asking questions and learning fast. Regulatory and financial domains have a lot of nuance — you bring curiosity and a willingness to dig in. Curiosity about financial infrastructure. Invoicing, VAT, compliance, payment flows. You don't need to be a domain expert on day one, but you're eager to go deep. Advanced AI adoption. You already use AI tools daily in your engineering workflow and you're always looking for new ways to apply them. You don't just accept suggestions, you prompt deliberately, iterate on output, and integrate AI into how you design, build, and debug. Strong collaboration and communication skills. This role sits at the intersection of engineering, finance, legal, and product. You build alignment fast and communicate clearly with non-technical stakeholders. Bonus: Experience with EU financial regulations, e-invoicing standards, or fiscalization Experience with payment service providers or payment infrastructure Familiarity with event-driven architectures (Kafka) or high-throughput data processing If the mission excites you but your experience isn't a perfect 1:1 match, apply anyway. We care about potential, not perfection. AI at Monta Engineering AI is central to how we build software at Monta. It's not a side experiment. It's embedded in our daily work and we expect every engineer to be a power user. Tools we use daily: Claude Code for writing, reviewing, and refactoring code, exploring domain problems, and building internal tooling Claude / Gemini for research, design thinking, and documentation Notion AI for docs,
