Build the future of cyber defence, before threats even exist. The Opportunity What if the code you wrote did not just power applications, but actively protected critical infrastructure across the world? This is an opportunity to work on a platform where performance, resilience, and security are not optional. They are essential. The Role We are looking for a Mid-Level Golang Backend Developer to join a team building a next-generation cyber security platform designed to safeguard industrial control systems. This role is ideal for someone who enjoys solving complex problems, cares deeply about secure software development, and wants their work to have real-world impact. What You Will Be Doing In this position, you will take ownership of developing and maintaining backend services written in Go. You will be working within a modern microservices architecture, designing systems that are scalable, reliable, and secure by design. Collaboration is key. You will work closely with engineers across disciplines to shape the platform's architecture and ensure everything integrates seamlessly. Security at the Core Security is at the core of everything you will do.

Nice to Have Experience in cyber security or DevSecOps would be a strong advantage, as would contributions to open-source projects or familiarity with frameworks such as OWASP, CIS Benchmarks, or ISO standards. However, what matters most is your willingness to learn and your drive to build secure, high-quality software. What You Get In return, you will be part of a team working on genuinely cutting-edge technology, in an environment that values innovation, collaboration, and continuous improvement. The role offers a competitive salary of £55,000 to £70,000, along with performance-based bonuses and opportunities for professional growth.
