Build What Powers the Future — As an Owner
At HDR, you don’t just work on projects — you help shape them. As a 100% employee-owned company, every person here has a stake in what we build and how we deliver it. That ownership mindset drives accountability, collaboration, and a shared commitment to excellence across everything we do.
For more than 25 years, our employee ownership model has empowered our teams to think beyond individual roles — to act with purpose, support one another, and deliver meaningful outcomes for clients and communities. It’s a culture where your contribution directly influences success, and where ideas turn into impact.
The Opportunity
We will be looking for experienced Commissioning Engineers and Commissioning Managers — both permanent hires and contractors — to join a major hyperscale data center project near Lisbon.
This is a chance to be part of a high-performing, multidisciplinary team delivering mission-critical infrastructure at scale. You will play a central role in ensuring systems are designed, tested, and delivered to the highest standards — contributing directly to the reliability and performance of a landmark project.

Coordinate with stakeholders to ensure alignment on certification and quality objectives
Perform inspections, testing, and reporting across systems
Support technical design reviews and construction-phase commissioning activities
Represent the commissioning perspective in project and client meetings
Oversee factory testing, third-party validations, and final sign-offs
Provide technical expertise in risk management and system performance
Collaborate closely with contractors and project teams to deliver integrated solutions
