Full Stack Engineer

About the role

We are looking for a Full Stack Engineer with solid fundamentals in both backend and frontend technologies to join one of our agile teams. You'll work alongside experienced engineers who will help you grow your skills across the full development stack. Your day-to-day work will involve building features that span both the backend (Java, Spring) and frontend (React, JavaScript), learning how these systems work together, and gradually taking on more ownership as you develop your expertise. You'll be part of a collaborative team (typically 6-10 people) working in support of our Customer Service functions.

You'll be involved in the full system/development life cycle from design discussions with your colleagues to the care of our products in production. In this role, you'll develop a deep understanding of how frontend and backend systems interact, while focusing on building scalable, maintainable services to power our customer service back offices.

This is a great role if you're ready to deepen your technical knowledge, learn best practices from experienced engineers, and grow into a senior engineer.

Our Tech Stack

Our technology stack includes;

Java, Spring, Spring Boot, JMS, Hibernate, JSON, Solace, Spring Cloud Stream
JavaScript, TypeScript, React, Redux
CSS, UI libraries and HTML
Oracle, Couchbase
Git, Maven, Docker, Kubernetes, Jenkins, Snyk, SonarQube, Splunk, Grafana, Swagger
REST APIs and event-driven systems
CI/CD using Argo CD

To excel in this role, we believe you…

Have foundational experience working as a Backend or Full Stack Developer/Engineer—you understand Java fundamentals and have worked with Spring or similar frameworks
Have practical experience building user interfaces with JavaScript, TypeScript, and React—you know how to structure components and handle state
Understand how frontend and backend systems connect via REST APIs and can build features that span both layers
Have used testing frameworks like Jest or JUnit and understand why testing matters
Have worked with version control (Git) and are familiar with CI/CD concepts like automated testing and deployment pipelines
Are comfortable troubleshooting code issues and asking for help when needed—you know how to use logs, debugging tools, and your team
Are eager to learn and grow; you're not afraid to ask questions and take on new challenges in a supportive environment
Enjoy collaborating with teammates and are open to feedback on your code and approach

In addition, you…

Are a positive person by nature and genuinely enjoy working with others—you see collaboration as a strength
Have good communication skills; you can explain your ideas clearly and listen to feedback without defensiveness
Are curious and want to understand not just how to solve a problem, but why the solution works
Believe you still have a lot to learn, and you approach challenges with humility and enthusiasm
Are open to trying new tools and approaches to improve your work
Have used AI-assisted coding tools (like Cursor, GitHub Copilot, or ChatGPT) to help you write or understand code—you're comfortable with AI as a learning and productivity tool
Have experience asking AI tools to help debug code, explain concepts, or suggest improvements

And if you come with following experiences we will be thrilled!

Familiarity with event-driven systems or microservices architecture—even just understanding the concepts
Have any exposure to secure development practices or tools like OWASP or SNYK

your career, we'd love to hear from you. This role is not just about where you are now — it's about where you're headed.
