GScan utilizes cutting-edge muon tomography technology to detect objects and chemical changes up to 10 meters deep within critical infrastructure. Their muonFLUX© system is a non-destructive testing and structural health monitoring solution that provides asset owners with enhanced visibility into issues like internal corrosion. This allows for proactive, data-driven decisions to maintain infrastructure more cost-effectively, safely, and productively. The technology offers high-resolution 3D imaging, deep penetration, and AI-powered analysis for a range of industries including infrastructure, security, transport, energy, and real estate. GScan's approach emphasizes sustainability by extending the life of existing assets and reducing the need for new construction, thereby saving costs and carbon emissions. The company has a global presence with offices in Estonia, the UK, and Germany.

About us
Welcome to GScan 👋 — we’re pioneering the future of non-destructive testing and structural health monitoring with the most advanced muon tomography technology on the market. Using naturally occurring cosmic rays (muons), our muonFLUX© system can see inside critical infrastructure such as bridges, tunnels, and buildings, detecting corrosion, voids, material loss, and other hidden defects with unprecedented clarity.
Unlike traditional NDT methods such as radar, ultrasound, muon tomography penetrates deep through concrete and steel, even at large thicknesses. Our technology is the only solution capable of capturing particles that pass through every material, producing highly accurate 3D models with up to 30x greater resolution than current market standards. For asset owners, this enables proactive, evidence-based maintenance, safer decision-making, and major cost savings.
Our award-winning technology is steadily gaining international traction, with deployments on 10 in-service bridges and assets across England, Wales, Scotland, the Netherlands, Estonia, and Spain as of 2025. We have been recognised in the UK as the
Leading global engineering company, AtkinsRéalis, shared their insights about our technology in this article.

Our recent progress in Germany
A message from our CEO, Marek Helm
"As the interest and demand for GScan’s technology rapidly grows in Germany and across Europe, we have made a strategic commitment to the German market. Following initial success and the start of our cooperation with BAM, we are now hiring our first technical expert in the country.
As our key engineering partner in Germany, you’ll lead projects from the first meeting to the final scan. Your contribution will help civil and structural engineers understand our innovative technology and see how it brings real value to their bridge projects.”
🚀 Your mission
How We’ll Work Together?
You’ll join us in a remote-first setup , working comfortably from your home office anywhere in Germany. For technology deployments at bridge sites, you will travel to customer locations, field deployments, or industry events within the DACH region, although the majority of collaboration is conducted online.
Who will you be working with?
Reporting and Collaboration : You will partner with our Germany-based CEO Marek Helm and Andreas Schneider from the Business Development Team. You will collaborate closely with Rufus Foster (Technical Director, Lead Bridge Engineer) and with Märt Mägi (CTO, Co-founder), Madis Kiisk (Chief Science Officer, co-founder), Jüri Saarma (COO) from the the GScan's management team and with Andres Nurme (Global Deployment Manager).
Interdisciplinary Exposure: As you advance our technology, you will have the chance to collaborate with an interdisciplinary group of experts across the company, including civil engineers, particle physicists, electronics and hardware engineers, ML/AI specialists, and software developers.

What makes working at GScan unique?
🌍 An opportunity to change the world & shape industry standards. Work with real global innovation and technological breakthroughs where a significant amount of decisions have not been made yet. Your work will influence new norms in infrastructure safety, maintenance, and digital modelling.
💡 Solve complex technical challenges. Collaborate with our Civil Engineering team, physicists, hardware engineers, and project and data scientists to refine how scanning is applied in real projects.
💼 Work together with industry leaders. With a strong interest in our cutting-edge technology, you will have the opportunity to talk with companies like Kiwa, Drees&Sommer, Implenia, Strabag, TÜV SÜD, working on high-profile projects that shape the future of infrastructure inspection and maintenance.
💥 Create real impact. Help stakeholders of built world management to prevent failure, reduce costs, and dramatically cut CO₂ emissions.
🔩 Go beyond conventional NDT. Apply your civil engineering expertise with cutting-edge scanning that reveals what others can't see.
🤝 Grow with purpose. Join a mission-driven deep tech start-up during an exciting early (yet not too early) stage. Our team has grown to 50+ talents, we have reached €1,5M annual revenue milestone (and growing rapidly!), successfully raised 6mln+ of investments (supported by 12mln+ in grants).
🔄End-to-end visibility. Unlike in siloed engineering roles, you'll be involved from concept to deployment — pre-sales, planning, field testing, and project delivery.
