Backend Developer (Java)

Do you want to build the backend infrastructure that delivers wellbeing to employees across Europe?

Are you ready to join one of Europe's fastest-growing companies? Do you want your code to power products that improve daily work life for millions of users?

If yes, join us to make an impact in a fast-paced engineering environment where you'll own backend services end-to-end, ship reliable APIs consumed by mobile and web teams, and contribute to a platform that reaches employers and employees across multiple markets.

Epassi's purpose is to boost everyday wellbeing. We are a leading provider of employee benefit solutions across Europe. Established in Finland in 2007, we were the first company to launch a mobile-payable employee benefit solution in Europe. Since then, we have consistently grown, diversifying our products and expanding into new markets. Epassi has been recognised by the Financial Times as one of the fastest-growing companies in Europe on multiple occasions.

We are currently hiring a Software Engineer (Java) based in Milan (hybrid work).

Your mission at Epassi

You will report to the Head of Engineering Italy and join a backend engineering team. You'll own your service areas end-to-end - from design through to production and collaborate closely with mobile and web engineers to ship features that are reliable, well-documented, and built to last.

This is a hands-on technical role for someone who takes quality seriously, integrates well into a team, and doesn't need close supervision to deliver. Your work will directly power Epassi's B2C consumer and B2B merchant platforms.

Your responsibilities will be:

• Build and maintain Java-based microservices that power both the B2C and B2B platforms, following API-first principles

• Deliver features end-to-end, from implementation through testing and release

• Design clean, well-documented REST APIs consumed by web and mobile clients, with backward compatibility and versioning discipline

• Align on API contracts, data models, and integration patterns early in the development cycle

• Write unit and integration tests that give the team genuine confidence in what you ship

• Own incidents within your service areas, contribute to post-mortems, and follow through on fixes

• Participate actively in code review, maintaining and helping refine team engineering standards

• Identify and address technical debt within your service areas as your confidence in the codebase grows

You'll be successful in this role if you:

• Deliver features end-to-end without close supervision, fully autonomous on the team's stack within your first 6 - 12 months

• Ship APIs that are well-documented, consistent with team conventions, and require minimal rework after review

• Earn positive feedback from mobile and web engineers - integration issues caught early, not at delivery

• Contribute meaningfully to at least one cross-cutting improvement, whether in testing, observability, tooling, or performance

What you should bring:

• 3+ years of professional backend engineering experience building production services in Java

• Hands-on experience with microservices using Spring Boot or equivalent framework

• Solid understanding of REST API design, including versioning, error handling, and OpenAPI documentation

• Working knowledge of AWS core services in a production context - ECS, Lambda, RDS, S3, CloudWatch

• Familiarity with Docker and containerised deployments

• Experience using AI coding tools (e.g. GitHub Copilot, Claude) as a genuine productivity multiplier

• A team-first mindset: you respect established patterns, integrate well, and contribute ideas constructively

Your language profile:

Fluent Italian & English required, written and spoken.

Why you should join us

• Be part of an ambitious growth journey and join a global community of driven, bold, entrepreneurial - yet grounded - Epassians in a company that is constantly evolving.
• Work with a clear purpose - boosting everyday wellbeing - and create a meaningful, positive impact on both individuals and society.
