Your mission will be…

We’re looking for an experienced Java Developer who enjoys solving challenging technical problems, understanding complex applications, and turning existing solutions into more maintainable, reliable, and secure software.

You’ll join an international project environment where your contribution goes beyond writing code. You’ll have the opportunity to take ownership, improve established applications, tackle technical debt, and help shape their future evolution.

What you’ll do

Develop, maintain, and continuously improve business-critical software solutions.
Understand existing applications, challenge the status quo, and identify opportunities for modernization and improvement.
Refactor legacy components while protecting stability and business continuity.
Investigate complex issues, identify root causes, and implement sustainable solutions.
Ensure high standards for software quality, maintainability, security, and documentation.
Support integration, deployment, and operational readiness across the application lifecycle.
Translate business and functional needs into effective software solutions.
Collaborate closely with developers, testers, architects, and project stakeholders across an international environment.
Take ownership of your topics and proactively communicate progress, dependencies, and risks.

We are looking for someone with…

Bachelor’s degree in Computer Science, Software Engineering, IT, Engineering, or a comparable technical field, or equivalent relevant professional experience.
4+ years of professional Java development experience, with a strong backend focus.
Strong knowledge of Java EE / J2EE applications and architectures.
Experience maintaining and refactoring legacy applications.
Strong knowledge of WebLogic and JBoss, including configuration, troubleshooting, and optimization.
Solid SQL and PL/SQL skills, particularly with Oracle Database and PostgreSQL.
Good understanding of TCP/IP communication and system integration.
Experience with Subversion (SVN), Ant, Eclipse, and MagicDraw.
Basic Windows administration and troubleshooting knowledge.
Experience with MES or manufacturing environments is a plus.
English is mandatory, as you’ll work and communicate in an international project environment.
Occasional travel may be required for project activities, workshops, or team collaboration.

What makes you a great fit

You’re someone who enjoys digging into complex systems and understanding how things really work. You combine technical expertise with ownership, curiosity, attention to detail, and a strong quality and security mindset.

You’re comfortable working autonomously, but you also recognize that great software is built through collaboration and knowledge sharing.

What We Offer

Belong & Innovate: Work in diverse teams where every idea matters and innovation grows through collaboration and trust.
Flexibility that Works: Hybrid model, flexible hours, and a home office budget — because balance fuels performance.
Health & Well-being: Comprehensive health insurance, mental health support, and active sports communities to keep you feeling your best.
Grow Without Limits: Access world-class learning platforms, mentoring, and continuous development opportunities.
