About the job

Tax? Yes, tax filings and tax law are the domains we design and build for, so having an interest in those areas would be good. Actual experience and domain knowledge are of course a plus, but certainly not a requirement. It's a pretty small Venn diagram of senior fullstack engineers who also have professional tax experience.

About You

As a fullstack engineer, you will be entrusted with building comprehensive tax automation tools and AI-integrated platforms across several business-critical products, working with both frontend and backend technologies.

As a master of your craft, you will write beautiful and performant React/TypeScript applications and robust Node.js services. Code that is well-tested, documented, optimized for speed, and easy to maintain across the full technology stack.

You have honed those skills over the years by working on complex fullstack applications in cross-functional product teams, where you have shown yourself as a wonderful collaborator who can seamlessly bridge frontend user experiences with backend system design.

Your Key Responsibilities

• Building end-to-end tax automation features from React frontends to Node.js backends
• Developing AI-integrated platforms with seamless user experiences and robust data processing
• Close collaboration with designers, product managers, ML engineers, and fellow developers
• Spending time, occasionally, with users and user researchers to understand tax workflows in detail
• Working across a range of products and problem spaces in the fullstack domain
• Freedom to work remotely or in our Copenhagen or Stockholm office

Skills And Attributes for Success

To qualify for the role, you should have:

Frontend Expertise (Required):

• React/TypeScript : 3+ years with modern hooks, state management, and performance optimization
• Modern Tooling : Experience with build tools (Vite/webpack), testing frameworks (Cypress/Jest), and Kubernetes deployments
• Complex UI Development : Building multi-step workflows, sophisticated form validation, and responsive interfaces

Backend Proficiency (Required):

• Node.js : 3+ years with Express, async programming, and RESTful API development
• MongoDB : Strong experience with document design, aggregation pipelines, and performance optimization
• Python Integration : Experience with FastAPI, report generation, and GenAI pipeline integration
• System Integration : Third-party API integration, microservices patterns, and MCP implementations

For Mid-Level Candidates (3-5 years):

• 3+ years fullstack development experience with shipped major features
• Solid understanding of full development lifecycle from design to deployment
• Proven cross-functional team collaboration experience

For Senior Candidates (5+ years):

• 5+ years with increasing technical responsibility
• Experience mentoring developers and making technical architectural decisions
• System design knowledge and scalability considerations
• Project leadership capabilities and scope definition skills

Additional Requirements:

• Easy access to Copenhagen, Helsinki, or Stockholm. You can work remotely most of the time, but we meet up in person weekly
• Really good English speaking and writing skills. That's our work language
• An interest in tax law and financial technology applications

What We Look For

We obviously want you to be a skilled fullstack developer, but we believe that a mid-to-senior engineer is so much more than that. We are looking for a colleague who is…

• A real craftsperson and a stickler for details across both frontend and backend code
• Delightful to be around and able to communicate technical concepts to both technical and non-technical stakeholders
• A clear communicator who can bridge the gap between user experience and system architecture
• Supportive and helpful in mentoring junior developers and sharing knowledge
• Quick to solve complex problems spanning the entire technology stack
• Questioning technical approaches and architectural decisions before committing to implementation
• Eager to learn about both advancing fullstack technologies and tax domain complexities
• Comfortable working in 6-week Shape Up cycles with autonomous project ownership
• Practical engineering mindset focused on shipping solutions that matter to users

What We Offer

• A tech product team : Digital product organization as a unit operates mostly product- and user-driven, even though we are situated within a large consultancy organization
• Direct access to users : Your fullstack solutions will directly impact tax professionals who are quite literally right next to you, providing immediate feedback on both UX and system performance
• Full-stack ownership : Take features from concept to deployment with complete technical ownership
• Shape Up methodology : Work in focused 6-week cycles with clear scope and technical autonomy
• Technology growth : Work with other great Engineers on React patterns, Node.js performance optimization, and AI integration challenges among other things.
• Good food and good times : We take good care of the people who dedicate their working hours to our cause
• Diverse and inclusive culture : You'll be embraced for who you are and empowered to use your voice to help others find theirs
