You’ll become part of a multidisciplinary team of senior engineers with a high level of autonomy, strong ownership, and real influence on solution architecture.
The team values knowledge sharing, close collaboration, and a friendly working atmosphere.
What you’ll be working on
In this role, you’ll be responsible for the full software development lifecycle, from analysing a topic and designing the solution architecture to implementation, automated testing, and deployment.
Your responsibilities will include
Designing and implementing microservices following Hexagonal Architecture principles
Actively contributing to architectural decisions and solution design
Building event-driven integrations using Kafka, Avro, and Transactional Outbox
Writing comprehensive automated tests, including unit, integration, and contract tests
Participating in code reviews and maintaining high code-quality standards
Taking ownership of assigned topics, identifying relevant stakeholders, and independently gathering the information needed to deliver solutions end-to-end
Using AI-assisted development tools such as Claude Code as part of your daily development workflow
Tech stack
Java 21
Spring Boot 3.x / 4.x, MVC & WebFlux

We’re looking for a Senior-level Software Developer who has
Strong experience with Java 21+ and Spring Boot, including MVC and/or WebFlux
Hands-on experience with Kafka

Good understanding of Hexagonal / Clean Architecture and microservices patterns
Experience with automated testing, such as Spock or JUnit, Testcontainers, and contract testing
Experience with Kubernetes, Helm, and GitLab CI

Proficiency with AI coding tools. Claude Code is the company standard, while experience with equivalent agentic coding tools such as GitHub Copilot or Cursor is also relevant
The challenges
You’ll be working within a highly complex distributed environment consisting of dozens of microservices and numerous communication channels. Understanding the wider system landscape will be just as important as working effectively with individual components.
The role also comes with a high degree of autonomy from day one. You’ll be expected to independently analyse topics, identify the right stakeholders, gather the necessary information, and take ownership of delivering solutions end-to-end.
AI-assisted development is an integral part of the team’s way of working. Claude Code is used at scale, and working effectively in an agentic, AI-first development workflow is a core expectation for this position.
Please note that while the role is remote, the final stage of the recruitment process is conducted in person at our Warsaw office, so candidates are expected to be available and willing to travel to Warsaw for this meeting.
