Why Sword?

Sword is an IT services and consulting company with a global presence and more than 3,000 employees. Our headquarters are in Luxembourg, where over 200 people support European institutions, private companies and the Luxembourg public sector with complex IT projects.

When you choose an employer, the assignment matters, but so does what it brings you in the longer term: what you will learn, the skills you want to develop, and the people you can talk to about your career. At Sword, the assignment is a starting point. It is part of a career path that continues across other projects and clients.

Our management team comes from a technical background and understands what it means to work as a consultant. Technology plays a real part in our decision-making, and that field experience shows in the way we support you day to day:

• A team leader from your technical area, also a consultant on assignment, who supports you with your performance reviews, skills development and training.

• A dedicated training and certification budget, giving you concrete resources to grow.

• The Global Reward Program, which recognises certifications, technical knowledge-sharing and referrals, among other things.

• A real company community: lunches, events and activities to connect with other teams, even while working at a client site.

• Satellite offices near Luxembourg's borders: depending on the arrangements with your client, you can work closer to home on certain days, while remaining on Luxembourg territory and within cross-border tax limits.

Sword is a certified Great Place to Work and was ranked 3rd among the Best Workplaces in Luxembourg in 2025.

We are hiring for several projects. Your application will be considered for all positions matching your profile.
