Full Stack Engineer

Company Description MindClon Inc. is a judgment infrastructure company focused on making high-stakes AI safer and more reliable in real-world settings. As AI moves from content generation and productivity tools into operational decisions, institutional workflows, and physical systems, MindClon builds technologies that help organizations govern AI actions within their own data, policy, and security boundaries. The company reduces reliance on stateless public APIs by enabling local inference, compute, and action governance tailored to sectors such as healthcare, defence, finance, insurance, law, and critical infrastructure. For Physical AI, including robotics, autonomous systems, and clinical devices, MindClon provides a judgment layer that helps systems decide whether to act, defer, escalate, or seek human confirmation. MindClon is dedicated to creating the judgment infrastructure needed as AI transitions from language to action and from screens to embodied intelligence. Role Description The Full Stack Engineer will design, develop, and maintain end-to-end web applications and services that support MindClon’s judgment infrastructure platform. This full-time, on-site role in the Greater Glasgow Area involves building scalable APIs, integrating front-end interfaces with back-end services, and collaborating with product and research teams to translate complex AI governance requirements into robust software solutions. Day-to-day responsibilities include implementing secure and efficient data flows, optimizing system performance, writing clean and testable code, and participating in code reviews. The engineer will also contribute to architecture decisions, deploy and monitor production systems, and help improve development processes and tooling.
