Job description

Expert Backend Engineer, Finance Platform (Java/Kotlin, GCP)

Shape the future of retail tech, one elegant solution at a time

How do you make our customers happy?

By crafting robust, scalable solutions that power delightful experiences for 13.5 million customers and 50,000 partner sellers. You'll join a vibrant tech community where curiosity drives innovation and collaboration breeds excellence. Whether you're passionate about enhancing the user experience, data engineering, platform reliability, developing fintech or marketing solutions, there's a place for you to make your mark on one of the most open and diverse retail tech platforms.

The biggest challenge

To create elegant solutions in a complex, rapidly evolving landscape. Our tech stack serves millions of interactions across multiple domains - from search and personalization to logistics and payments. You'll need to strike the right balance between technical excellence and pragmatic delivery, while collaborating across teams to ensure solutions scale gracefully. The good news? You'll have the support of a community that values diverse perspectives and believes the best code comes from teams where everyone's voice is heard.

What you'll do as Software Engineer

You'll be part of a product engineering team that owns its systems from design to production. We value autonomy, technical excellence, and continuous improvement, empowering engineers to make meaningful decisions about architecture, processes, and delivery.

In the Finance Engineering team, you'll work on services that form the foundation of bol's financial ecosystem. Our systems consume and process business events generated across the organization, transforming them into accurate financial records that drive downstream finance processes. Every order, payment, invoice, and adjustment depends on the reliability of the platforms we build.

This is a role where engineering quality and business impact go hand in hand. You'll tackle challenges around scalability, reliability, observability, and data integrity, while collaborating closely with finance and product stakeholders. The solutions you build will be essential to ensuring financial accuracy and supporting the growth of the business at scale.

Tech stack: Java, Kotlin, GCP, Spring Boot, and Apache Flink is a big plus

As a Software Engineer you are expected to:

• Design and develop scalable, resilient microservices
• Collaborate with product managers and designers to refine solutions
• Write clean, maintainable code with comprehensive test coverage
• Champion best practices in system design and software engineering
• Contribute to decisions that help shape our technical landscape
• Participate in code reviews to share knowledge and ensure quality
• Help operate the services you build, embracing our DevOps culture
• Excellent communicator and collaborator
• Solid architectural and solution design skills

• Craftsmanship champion

  You write code that makes other engineers smile, combining technical experience (8+ years in relevant roles) with a pragmatic mindset

• Collaborative innovator

  You feel at home in settings where ideas are valued for their merit, not their source

• Continuous developer

  You see every challenge as a learning opportunity and aren't afraid to venture beyond your comfort zone

• Lone lion(ess)

  You prefer to work in isolation; team collaboration is an unnecessary complication

• Feature factory worker

  You're more interested in churning out features than their actual impact

• Comfort zone dweller

  Learning new technologies and adapting to change? That sounds exhausting!

This is where you'll work

Join a tech community that's reinventing retail through continuous innovation. You'll work alongside passionate engineers who believe in autonomy, continuous learning, and the power of diverse perspectives. Our modern office in Utrecht feels more like a tech campus than a corporate HQ, complete with game rooms and a soccer field. While we take our mission seriously, we keep our culture light and collaborative - because we believe the best solutions come from teams that enjoy working together.
