Java Developer (Mid-Senior) with Python

Remote in EU | B2B Contract

Role OverviewWe are looking for a strong Java Engineer (mid-senior level) who will work across several internal services at the same time, shaping backend architecture, contributing to product decisions, and supporting multiple engineering teams. This is not a single-project assignment - you will touch 3–4 microservices in parallel, work closely with Product Owners, and bring a strong technical point of view.

The ideal person is hands-on, analytical, comfortable with cloud-native environments, and open to working with AI-supported solutions as part of modern engineering. We are particularly interested in engineers who are close to senior level and demonstrate strong ownership and problem-solving skills.

Key Responsibilities:

• Build and maintain backend services and APIs in Java
• Work across multiple microservices (3–4) simultaneously
• Collaborate closely with Product Owners on technical direction
• Contribute to cloud-native architecture on AWS (90%) + Azure (10%)
• Deploy and operate services using Kubernetes and Docker (must-have)
• Contribute to Python-based services when needed
• Work with analytics and data insights to support decisions
• Follow SDLC best practices: testing, code reviews, documentation
• Collaborate with DevOps on CI/CD, deployments, scaling
