Senior Mechanical Engineer

Quantum computing is moving from research to reality and the hardware behind it is finally becoming the bottleneck. At SCALINQ we build cryogenic systems at the edge of what materials precision and physics allow and were looking for a senior mechanical engineer who wants to turn difficult ideas into working products. Curious to learn more Read on.

Senior Mechanical Engineer
As a Senior Mechanical Engineer at SCALINQ you will take a central technical role in developing advanced cryogenic hardware for quantum computing. This is a hands-on role where you design build test and iterate while also guiding and supporting more junior engineers.

You will work across the full development cycle from early concepts and CAD design to experimental validation supplier interaction process improvement and close collaboration with electrical production and sales teams. Your work will not stop at drawings; you will help take designs all the way to production-ready hardware and real customer deployment.

This role is for someone who thrives on responsibility fast decisions and solving complex problems in an environment where priorities shift constraints are real and progress matters.

What We Offer You
At SCALINQ you will work on technology that enables a fundamental shift in how computing is built. We move fast expect initiative and give engineers real ownership ideas turn into production-ready products and reach global customers within a year. You will work hands-on with cryogenic hardware unconventional materials and high-precision systems using state-of-the-art tools in close collaboration with academia suppliers and customers. This is a trust-based environment with high expectations continuous technical challenge and rapid professional growth where impact matters more than titles or hierarchy.

Who We Are Looking For
We are looking for a highly experienced mechanical engineer with a strong technical foundation and a clear drive to build things that are hard. You are comfortable taking ownership of complex poorly defined problems and making decisions without having perfect information. You combine confidence in your expertise with curiosity and humility and you actively seek to learn from others and challenge your own assumptions. You thrive in fast-paced environments with ambitious goals non-conventional products and tight collaboration across engineering disciplines. You value solving hard problems together with highly competent colleagues and know when to ask for input. You are structured proactive and energized by technical challenges and you naturally take on a guiding role by mentoring junior engineers while staying deeply hands-on yourself. You lead by example set technical direction when needed and create clarity for others in complex situations. This is not a role with fixed boundaries it is one you help define.

About SCALINQ
At SCALINQ the team is at the core of everything we do. By bringing together expertise in quantum technology microwave engineering and hardware design we develop high-performance hardware solutions that enable the scaling of quantum computers. Rooted in research our products include advanced RF packaging high-density interconnects and cryogenic components designed to meet the real-world constraints of quantum computing.

With strong ties to Chalmers University of Technology in Sweden we combine global scientific expertise with Gothenburgs practical collaborative engineering culture. Innovation at SCALINQ happens through close interaction between research and engineering with a clear focus on turning complex ideas into robust deployable hardware.
