Skills required: A minimum of 5 years experience as a QA engineer/analyst Proven experience in a QA role with a strong emphasis on test planning and requirements analysis. Solid experience in test automation for complex, distributed systems. Demonstrable knowledge of testing front-end applications (React, TypeScript) and back-end services (Node.js). Experience in setting up and managing test environments, particularly with containerization and orchestration (Kubernetes). Experience with QA for machine learning projects, including automated testing for LLM-based technology. A deep understanding of the software development lifecycle and agile methodologies. Good understanding of the role of quality in an LLM assisted team Must be able to obtain and maintain Security Vetted status to at least SC level. Skills desired: Experience with performance critical systems. Previous experience in a leadership or mentoring role. Familiarity with CI/CD pipelines and DevOps practices. A passion for working with cutting edge AI and simulation technologies. Experience working in the defence sector. Job Benefits We make Hadean an awesome place to work with competitive benefits Hybrid working with 1 day per week in our fantastic office in Shoreditch, London Private Health Insurance Enhanced pension scheme Enhanced parental leave 3 extra days off at Christmas (on top of our standard 25) L&D budget Regularly scheduled socials Share options A Place For Everyone We believe diversity drives innovation and for that reason we strongly encourage those from all backgrounds to apply for roles at Hadean.

Our platform enables real-time simulation and training, mission rehearsal, command & control and digital twin capabilities - transforming the way defence, government agencies and enterprises plan, train, and make decisions. We work at the forefront of defence innovation, collaborating with global partners to deliver next-generation capabilities that unlock operational advantage. The Team dominAI is a close-knit team of highly technical, deeply collaborative engineers - each bringing genuine specialism to a shared mission. We move fast, hold each other to a high standard, and take real pride in what we ship. We work in sprints, building MVPs that are regularly taken out to industry events, integration hackathons, and live demonstrators. There's no waiting months to see your work matter - the feedback loop between building and showing is tight, and it shapes what we build next. We're also a team that invests in itself: continuous learning, honest retrospectives, and a genuine culture of craft are part of how we operate. This is a brand new product for Hadean. We're building it quickly and building it right - and the people who join now will shape its direction. The Role As a Full Stack Software Engineer in our dominAI team, you will take a leading role in shaping the interface, architecture, and interaction of our next-generation command and control platform - a system that embeds AI and large-scale simulation directly into the C2 workflow, enabling commanders to plan and assess targeting outcomes in minutes rather than hours. You will work within a cross-functional team of AI, simulation, and infrastructure specialists, contributing across the full stack: from architecting robust backend services that integrate with simulation and AI pipelines, to building the sophisticated web interfaces through which commanders and staff interact with that capability. You will act as a technical mentor for web engineering across the team, and bring the full-stack instincts needed to make good architectural decisions at the boundary between frontend and backend. Key Responsibilities Architect and implement backend services in Node.js that integrate with AI inference pipelines and simulation systems. Design and maintain data models that accurately represent and propagate simulation and operational state across the platform. Develop and maintain the dominAI web application using React and TypeScript, building reliable and performant interfaces for complex operational data. Architect efficient data flows between the web frontend and our distributed backend systems. Mentor and upskill other engineers in web engineering best practices and modern full-stack patterns. Collaborate with UX designers to create clear, high-impact interfaces for complex data sets. Work with the Product Manager to refine technical requirements and provide well-reasoned estimates across the stack. Maintain a high bar for code quality through testing with Vitest and rigorous peer reviews. Skills, Knowledge and Experience A degree in Computer Science, Software Engineering, or a related field Extensive professional experience building complex web applications with React and TypeScript. Strong proficiency in Node.js for building scalable, production-grade backend services. Solid understanding of API design, data modelling, and backend integration patterns - comfortable owning services end-to-end. Experience with modern frontend tooling and state management (e.g. Vite, Zustand, and Immer). A "generalising specialist" mindset - you have depth in web engineering but are comfortable and effective moving across the stack. Proven ability to mentor other developers in a collaborative engineering environment. Strong communication skills with the ability to discuss technical trade-offs with both engineering and product stakeholders. Ability to obtain and maintain UK Security Vetted status to at least SC level. Willingness to attend our office in Shoreditch at least once a week. What will help you stand out Experience with event-driven architectures, message queues, or real-time data systems. Familiarity with geospatial libraries such as OpenLayers or Cesium. Experience integrating with or building around AI services or simulation platforms. Knowledge of Supabase or similar Backend-as-a-Service platforms. Interest or familiarity with the defence sector, Military Modelling and Simulation, or C2 systems. An interest in travelling to support customer deployments, hackathons, and industry events. Job Benefits We make Hadean an awesome place to work with competitive benefits Hybrid working with 1 day per week in our fantastic office in Shoreditch, London Private Health Insurance Enhanced pension scheme Enhanced parental leave 3 extra days off at Christmas (on top of our standard 25) L&D budget Regularly scheduled socials Share options A Place For Everyone We believe diversity drives innovation and for that reason we strongly encourage those from all backgrounds to apply for roles at Hadean.
