In TeamTerminus, we develop core functionalities for the entire checkout process and buyer user management in the Unite ecosystem. Our goal is a seamless purchasing experience, high conversion, and a strong new Unite Procurement Portal (UPP). If you’re excited about working on business‑critical services and shaping a product that powers thousands of orders every day, we’d love to meet you.

Your role

• Be a team player: You’ll collaborate in an agile environment, and will work with a high degree of autonomy and strive to be a high-performing, self-managed and self-organised team. We encourage pair and mob programming— we work together and do things together.
• Add value: You'll develop and operate core services for our checkout and buyer user management, helping us finalise the UPP and close remaining feature gaps.
• Shape our engineering culture: You'll contribute to cross-team initiatives to define architectural guidelines, evaluate new technologies, and establish best practices.
• Take pride in craftsmanship: You'll foster a security-first mindset and ensure robust, reliable, clean and testable code.
• Turn complexity into working software: You'll analyse complex business requirements and work in close cooperation with the product team to translate them into production-ready code.
• Backend depth with Java: You're experienced in designing, developing and maintaining robust web applications in Java. You have a strong understanding of distributed systems, data modelling, and service-oriented and event-driven architectures.
• Full‑stack mindset: You either bring experience with TypeScript and React, or you’re excited to learn and grow into our frontend tech stack — both paths are perfectly fine for us.
• Strategic thinking: You have the confidence and maturity to maintain and modernise business-critical legacy code.
• Operational ownership: You're proficient with DevOps tools and practices and experienced in supporting the operation of highly available web services.
• Curious builder’s mindset : You stay curious, share knowledge, and use modern technologies from cloud services to AI‑powered tools — to continuously improve the way we build software.

What you can expect from us

• Be a part of our agile working style : Our open communication and quick decision‑making processes allow our teams to work autonomously for the most part.
• We offer a flexible work location : You can work in one of our modern Unite offices or remotely – or even do a mix of both.
• Workation : 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.
• Enjoy our Unite culture : We invite you to be yourself, join our table tennis league or online games and have fun.
• We think long‑term : You can and absolutely should invest an average of 10% of your working time into self‑education and your own further training – that’s why we are great believers in offering creative freedom. You’ll also get access to our internal learning platform to grow your career.
• Build with a rich and evolving technology ecosystem: AWS, Spring Boot, Kafka, Terraform or Wicket are just a few to mention. Also, we have a fully integrated CI/CD pipeline in GitLab.
