Amsterdam | Hybrid Work Model | Full-Time 

Do you want to build software where precision and reliability are key? 

At Nextens, we create robust tax software that helps businesses and professionals handle complex fiscal processes with confidence. We’re looking for a Senior Software Engineer who enjoys building scalable, maintainable, and accurate systems that make a real difference. 
 

About Us 

At Nextens, we build software that matters. Our solutions handle large volumes of data and support businesses and professionals with complex tax challenges. That means our systems must be reliable, accurate, and thoughtfully designed. 

We work with proven technologies like .NET Core, Azure, and Angular, with a focus on sustainable solutions and long-term improvements. In our team, you’ll tackle complex technical challenges and have the chance to fully apply your analytical skills. 

The software you develop processes millions of tax filings every year, contributing to fair, transparent, and efficient processes. Your work has a direct impact—what you build truly matters. 

Nextens is part of Lexis Nexis Risk Solutions (LNRS) and operates as an independent unit. Our close-knit, enthusiastic team of around 60 colleagues works every day to develop the full Nextens product suite. 
 

Your Role 

You’ll take ownership of complex technical areas, guide architectural decisions, and collaborate across teams. You love solving complex problems, and you take pride in building software that is accurate, well-structured, and future-proof. What you’ll do: 

Develop calculation algorithms to ensure flawless tax processing. Work with complex fiscal rules: from understanding and refining regulations to implementing robust solutions. Create and integrate submission messages for tax filings, ensuring compliance with relevant laws. Build reports and calculations that give customers clear, actionable insights. Collaborate closely with domain experts to optimize tax returns and create efficient, scalable systems. 

This is a role where deep technical expertise is essential. You’ll think critically, test thoroughly, and collaborate closely to deliver solutions that can be trusted. 

 

What You Bring 

A bachelor’s degree in computer science, Software Engineering, or relevant experience. 6+ years of software development experience, including .NET Core and Azure. Fluency in Dutch and a good command of English. Strong analytical skills and the ability to solve complex problems systematically. A collaborative mindset—someone who enjoys working with others to find practical solutions. 

 

Why Join Us? 

At Nextens, you’ll find a team that values expertise, collaboration, and continuous growth. We offer a hybrid work model, encourage professional development, and ensure a healthy balance between challenge and satisfaction. 

Here’s what you can expect: 

Direction: The opportunity to shape the technical direction of critical systems and make an impact. Impact: Your systems will process thousands of tax returns and support key fiscal processes. Technical challenge: Work on software that must be carefully designed and is critical for our customers. Hybrid working & flexibility: Work from home, collaborate at our modern office. Work-life balance: Generous vacation days, flexible hours, and 20 days a year to work from abroad. Professional growth: Deep-dive into a complex domain and expand your expertise.
