This role combines process engineering, process modelling, systems engineering, technology development, and program delivery responsibilities. The successful candidate will support the design, modelling, integration, testing, and maturation of tritium fuel cycle systems required for the deployment of Infinity Two and future commercial stellarator power plants. The role will contribute to the development of tritium extraction, processing, storage, isotope separation, fuel clean-up, detritiation, fuel delivery, and tritium accountancy systems. In parallel, the successful candidate will support the development of technology demonstrators and experimental facilities used to retire technical risk and increase the technology readiness of key fuel cycle systems prior to FPP deployment. The Tritium Engineer will work closely with the wider Tritium Plant organization, systems engineering teams, safety specialists, physics teams, external laboratories, industrial partners, and suppliers to deliver practical engineering solutions supporting the commercialization of fusion energy. The successful candidate will be expected to balance engineering design, process modelling, technology development, and program delivery activities while acting as a key interface between the Tritium Plant organization and external technology partners., * Support the design, development, integration, and deployment of tritium fuel cycle systems for Infinity Two and associated technology demonstrators. * Develop process engineering deliverables including Process Flow Diagrams (PFDs), Piping & Instrumentation Diagrams (P&IDs), engineering specifications, operating philosophies, equipment sizing calculations, and system design documentation. * Develop and maintain process models of tritium fuel cycle systems using engineering simulation tools such as Aspen Plus, Aspen HYSYS, MATLAB, Python, COMSOL, gPROMS, or equivalent platforms. * Perform process engineering analyses including mass and energy balances, process inventories, equipment performance assessments, process optimization studies, and design trade-off evaluations. * Support the development of plant-wide fuel cycle models, tritium accountancy methodologies, digital engineering tools, and digital twin capabilities. * Act as a system engineer for assigned fuel cycle subsystems, supporting progression through Conceptual, Preliminary, and Detailed Design phases. * Identify technology gaps, technical risks, and development opportunities and support maturation of fuel cycle technologies through experimental programmes, technology demonstrators, and research and development activities. * Support commissioning, testing, operation, and analysis of prototype facilities and technology demonstration systems, ensuring lessons learned are incorporated into future plant designs. * Work collaboratively with Tritium Scientists, Fuel Cycle Modelers, Systems Engineers, Safety Engineers, and Design Engineers to develop integrated fuel cycle solutions and support long-term fuel cycle architecture development. * Develop technical scopes of work, specifications, and engineering requirements for suppliers, contractors, and development partners, and support technical oversight of contracted activities. * Review technical deliverables, monitor progress against program milestones, and support project planning, cost estimation, schedule management, and risk mitigation activities. * Act as a technical interface with universities, national laboratories, industrial partners, suppliers, and regulatory stakeholders to support technology development and program execution. * Support hazard assessments, safety analyses, tritium inventory evaluations, and development of operating procedures to ensure compliance with applicable nuclear, industrial, and quality standards. ## Related Videos - [Data Science, ML & AI in the Oil and Gas Industry at NDT Global - Dr. Katja Träumner](https://www.wearedevelopers.com/videos/1308-data-science-ml-ai-in-the-oil-and-gas-industry-at-ndt-global-dr-katja-traumner) - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Automated Driving - Why is it so hard to introduce](https://www.wearedevelopers.com/videos/628-automated-driving-why-is-it-so-hard-to-introduce) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Engineering/Manager Pendulum: Generating compound interest on your career](https://www.wearedevelopers.com/videos/100348-engineering-manager-pendulum-generating-compound-interest-on-your-career) ## Related Articles - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [UK Business Culture and Etiquette](https://www.wearedevelopers.com/magazine/326-uk-business-culture-and-etiquette) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs)
