Your challenge

We are on the eve of international expansion into markets such as the UK and US. This brings complex issues of scalability, compliance and multi-region infrastructure. We are building a platform that functions smoothly across multiple countries, languages and legislations. And for that, we need you!

You will work in a cross-functional product team in which engineers, product managers, designers and analysts work closely together. Within your team, you get a lot of autonomy and the chance to make an impact.

What will you do?

• Actively contribute to the technical roadmap, code reviews and our way of working.

• Collaborate with designers to localise the existing front-end and develop and test new features.

• Develop smart automations for onboarding processes so that professionals worldwide quickly find relevant assignments.

• Working with AWS, Docker and event-driven architectures (RabbitMQ) to deliver a robust platform that meets international security, compliance and performance standards.

We are definitely a match if

• You have a passion for clean code and good testing.

• You have a can-do mentality and positive mindset.

• You enjoy working in teams, actively asking questions and are open to feedback.

• Proven experience applying AI coding agents such as Claude, Codex, GitHub Copilot, or similar tools in day-to-day engineering workflows.

• Ability to work effectively with AI-assisted development environments such as Cursor, VS Code, or equivalent tools, while maintaining high standards for code quality, testing, and security.

• You are energised by technical challenges and complexity.

• You are pragmatic in your approach - working software that delivers value is more important than perfection
