Arhs Group is a Luxembourg information technology company founded in 2003. It builds custom software, data platforms and digital systems largely for European Union institutions and public administrations. The group employs thousands of specialists and was acquired by Accenture.

Arηs Group, Part of Accenture, specializes in the management of complex public sector IT projects, including systems integration, informatics and analytics, solution implementation and program management. Our team helps lead clients through digital and information systems design, bringing expertise in a variety of areas ranging from software development, data science and security management to machine learning, cloud, and mobile development.

Arηs Group was acquired by Accenture in July 2024.

At ARHS Group, part of Accenture, we are strengthening our architecture expertise and are looking for an experienced IT Java Architect (m/f) to support the delivery of complex enterprise systems onsite in Luxembourg. This role combines strategic architecture ownership with hands-on technical leadership, contributing directly to the design and success of large-scale platforms within a collaborative delivery environment.

THE WORK:

  • Define and design end-to-end solution architectures for Java and web-based applications.
  • Translate business and functional requirements into scalable technical architectures and implementation blueprints.
  • Guide development teams on architecture best practices, design patterns, and technology selection.
  • Maintain hands-on involvement in development activities when needed, leading by example.

  • Review technical designs and code to enforce architectural standards and quality practices.
  • Collaborate closely with development teams, security specialists, and operations to ensure alignment across solutions.
  • Drive continuous improvement of development processes and technical standards.
  • Contribute to architecture documentation and knowledge sharing initiatives.

Onsite at client site: This role requires an onsite presence with our clients and partners to support project delivery and strengthen client relationships.

Our roles require in-person time to encourage collaboration, learning, and relationship-building with clients, colleagues, and communities. As an employer, we will be as flexible as possible to support your specific work/life needs.

HERE’S WHAT YOU’LL NEED:

  • Master’s degree in Computer Science or a related field.
  • 10+ years of experience in Java development, with proven background in architectural design or technical leadership roles.
  • Strong expertise in Java (Spring ecosystem) and web technologies such as Angular.
  • Experience delivering solutions in cloud environments and enterprise-scale systems.
  • Solid knowledge of SCRUM and Agile project delivery practices.
