Senior IT Infrastructure Specialist

With over 450 employees in seven global offices – from Amsterdam to Austin, Hong King to Dubai – UNS is more than an architecture firm. We’re a collective of thinkers, problem solvers, and creative minds working across disciplines to shape a better world. Whether it’s cities or airports, bridges or brands, we design solutions that address real societal challenges.

We rethink traditional ways of working – not just in design, but in how we collaborate, use technology, and plan for the future. We see IT as an integral part of this. By connecting tools, systems, and people in smarter ways, we empower our teams and contribute to greener, healthier, and more resilient communities.
