Senior Full-Stack Developer (Java or React Specialist), Ag. Paraskevi, Hybrid (4-1)

Our client is a global industrial leader listed on the NYSE, operating in over 35 countries with a workforce of 11,000+. Their Athens Tech Hub is a strategic center of excellence where 80+ IT professionals drive high-impact projects supporting global operations. Due to strategic expansion in Greece, they are looking for a Full-Stack Developer—with deep expertise in either Java or React and a passion to master both—to join a high-performing team responsible for a business-critical international platform.

The Role

As a Full-Stack Developer, you will help spearhead the high-impact architectural evolution of the client's enterprise commercial platform, transforming a legacy desktop suite into a cutting-edge, high-performance React and Java ecosystem.

We know that finding a true master of both ecosystems is rare. That’s why we are looking for a specialist who is excellent in one side of the stack and eager to level up in the other. You will enjoy the autonomy to learn, grow, and eventually own the full development lifecycle of a sophisticated global platform, integrating everything from complex CPQ logic to workflow automation, alongside an elite group of senior peers who will support your growth.

This is a unique opportunity to collaborate with top-tier international engineers, tackle complex technical debt, expand your stack, and leave a lasting legacy by shaping the future of a premier software suite used across our global footprint.

What you will bring

We are looking for a strong background in one of the two core pillars, combined with the drive to learn the other:

• The Java Pillar: 3-5+ years of experience (Java 17 preferred), focusing on back-end logic, system integrations, and performance.

  • If this is your strength, you are ready and excited to learn React 18+ on the job.

• The React Pillar: 3-5+ years with React (React 18 + Redux), building clean, maintainable, and responsive front-end interfaces.

  • If this is your strength, you are ready and excited to dive into modern Java backend architecture.

Core Technical Foundations:

• Database Management: Strong SQL Server skills, specifically in writing and optimizing complex queries for data-heavy applications.

• API Fundamentals: Expert knowledge of RESTful design, consumption, and performance tuning.

• Modern DevOps: Hands-on experience with Git (GitLab/GitHub) and CI/CD pipeline management.

• Communication: Professional English is required for collaboration with global teams.

Nice to Have

• Exposure to RabbitMQ or similar messaging systems.

• Experience navigating and refactoring monolithic environments.

• Familiarity with AI-assisted tools like GitHub Copilot.

What's in it for you

• Compensation: €35,000–€50,000 base salary plus a 10% annual performance bonus.

• Perks & Benefits: Ticket Restaurant card, private pension plan, and comprehensive private health and life insurance.

• Flexibility: Hybrid working with 1 day remote in a modern office in Agia Paraskevi.

• Growth: Dedicated mentorship to help you bridge the gap between Java and React, turning you into a true, high-market-value Full-Stack engineer.
