Software Engineer (Python)

Welcome to GScan 👋, we're pioneering the future of non-destructive testing and structural health monitoring with the most advanced technology on the market. Using cosmic rays (muons), our muonFLUX© system can see inside critical infrastructure such as bridges, tunnels, and buildings—detecting issues like corrosion and other hidden defects with unprecedented clarity.

Our groundbreaking technology is the only solution capable of detecting particles that pass through every material, including concrete and steel with dimensions more than 5 meters, producing highly accurate 3D models that deliver 30x greater accuracy than industry standards. For the first time, asset owners can make proactive, data-driven decisions to maintain their infrastructure in safer, more cost-effective, and sustainable ways. Here's a video explanation. Join the team that’s transforming the future of sustainable infrastructure!

🔹 Job type: This is a hybrid role; you can work from the office and partly remote.

🔹 Seniority: Mid-level

🔹 Job location: Our main offices are in Estonia (Tallinn and Tartu), and Cambridge, UK.
