Want to shape the future of procurement? At Unite, we’ve been working for over 25 years to make purchasing in the private and public sectors efficient, sustainable and compliant. We offer organisations a trusted alternative to non-European procurement platforms – strengthening local value creation and keeping data where it belongs. More than 700 employees around the world contribute to Unite’s development, bringing diverse perspectives and a strong sense of responsibility. Does this sound like you? Join us as we take procurement to the next level.

As a Fullstack Software Engineer (gn), you will help build and evolve software capabilities that enable Unite to turn complex business, customer, and operational data into reliable technical flows, automation, and customer-facing functionality.

You will work in a mixed technology landscape: modern backend services, legacy Java systems, React-based frontend applications, GraphQL integrations, microfrontends, CI/CD pipelines, and AWS-based infrastructure.

You will work with the team to not only deliver features, but to make systems easier to understand, safer to change, and more sustainable to operate.

Your role

  • Own the backend: You will design, implement, test, and maintain Java-based backend services, working with both modern and legacy Java systems.
  • Leave your mark on the frontend: You will work on React-based frontend applications, GraphQL integrations, microfrontends, and automated UI testing with Playwright.
  • Modernise existing systems pragmatically: You will help us improve maintainability, testability, API boundaries, and system decoupling without breaking business-critical flows.
  • Build software with production in mind: You will do more than writing code. You will help us build the infrastructure around it too. You will contribute to CI/CD pipelines, automated testing, infrastructure-as-code, cloud deployment, and the monitoring that tells us when something needs attention.
  • Bridge teams, not just systems: You will be part of a broader engineering community - working closely with architecture, platform, operations, and neighbouring engineering teams to clarify requirements and deliver sustainable solutions.
  • Use modern engineering practices responsibly: You will be encouraged to use AI-assisted engineering tools while keeping quality, security, and ownership clear.

Your qualifications

  • You have strong Java backend experience: You are confident designing, implementing, testing, and maintaining Java applications, ideally with Spring Boot or comparable frameworks.
  • You can contribute across the frontend: You have practical experience with React or comparable frontend technologies. Experience with GraphQL, microfrontends or Playwright is a plus.
  • You are comfortable with mixed system landscapes: You can work pragmatically with legacy code and modern services. You do not need perfect greenfield conditions to create value.
  • You think in systems, not only tickets: You care as much about clean APIs and clear domain boundaries as you do about the feature shipping. Maintainability, security, and observability aren't afterthoughts for you; they're part of how you define done.
  • You understand delivery engineering: You are passionate about CI/CD, automated testing, DevOps culture and infrastructure-as-code principles. Experience with AWS and Terraform is a plus.
  • You're a true team player: You communicate clearly, challenge assumptions constructively, support teammates, and help turn ambiguous requirements into working software.
  • You never stop learning: You are curious about new tools and engineering practices, including responsible use of AI in software development.

What you can expect from us

  • Autonomy and ownership: You will be part of an agile engineering team with room to shape solutions, improve systems, and contribute to ideas.
  • An office you'll enjoy coming to: Our office facilities are modern and ergonomic, public transport connections are excellent, and the on-site cafeteria serves freshly prepared meals every day – with a subsidy from us included. Hybrid working is also possible.
  • Learning time: You can invest an average of 10% of your working time into self-education and professional development.
  • A broad technology landscape: You will work with a rich and evolving ecosystem including Java, Spring Boot, React, GraphQL, AWS, GitLab CI/CD, Terraform, and modern engineering practices.
  • A team that values sustainable engineering: We care about building software that lasts: code others can build on, knowledge that gets shared, feedback that actually lands, and a way of working we never stop improving - together.
  • We offer workations for new possibilities: You can work abroad for up to 2 months, which is a great way to extend your time away or visit your family and friends in other countries.
  • We care about work-life balance: We offer flexible working hours and 30+ holidays so you can strike a good balance between your work and personal life.
