This is the job

Are you a seasoned engineer with a natural talent for leadership? We are looking for a Java Technical Lead to take ownership of our ICs core components. In this role, you won't just be writing code; you will be the architectural anchor for a backend team of senior developers, ensuring that our solutions are secure, scalable, and compliant with the highest industry standards. If you enjoy bridging the gap between high‑level architecture and hands‑on production stabilization, you’re the one we’re seeking.

This is you

• You have extensive experience in SW development and design at a lead or senior level.
• Java Mastery: You are an expert in Java 17 (ideally 21) and have a deep understanding of the JVM.
• Spring Specialist: You have hands‑on experience with Spring Boot 3.x, including REST API design, Actuator, and complex exception handling.
• Architectural Mindset: You are comfortable with modular monoliths and understand the importance of idempotency, retries, and a clear separation of concerns.
• Security First: You have a strong grasp of mTLS (certificates, keystore/truststore) and OWASP security principles.
• Integration Expert: You are proficient in both REST and SOAP, with specific experience in XML processing (JAXB, XSD).
• Operational Pro: You have experience with production troubleshooting and monitoring (Nagios‑compatible endpoints).
• Communicator: You can effectively coordinate with DevOps, Data teams, and external technical stakeholders (OPAP).
• Language: English on a business level.

This is your role

• Technical Leadership: Lead and mentor a backend team of two Senior Developers.
• Architectural Ownership: Take responsibility for the backend architecture of ICs core components and API design.
• Quality & Compliance: Be accountable for technical quality, security standards, and regulatory compliance.
• Cross‑team Coordination: Collaborate with DevOps on HA/DR and infrastructure, and sync with Data/Integration teams.
• End‑to‑End Support: Provide technical guidance during UAT, Go‑Live, and certification phases.
• Tech Stack: Java 17/21, Spring Boot 3.x, MS SQL, SOAP/REST, Docker, Maven, and Git.

What awaits you at Avenga?

• Pleasant working environment and stable background in one of the largest software development companies in the world.
• Space to work independently and creatively with the possibility to implement your own ideas and opportunities to learn new things and approaches.
• You have the opportunity to influence your direction in the company.
• High quality hardware and software, access to the latest technologies and specific projects.
• At Avenga, you’ll get quality support in your development thanks to a wide range of internal and external training courses, so you can push the boundaries of your competences.
• We offer a variety of benefits tailored to your location and type of cooperation.
