In-vessel and blanket systems must combine low activation, thermal and mechanical performance, resistance to irradiation and corrosion, tritium control, manufacturability and a credible industrial supply chain. These requirements involve metals, ceramics, composites, coatings, joints and breeder or shielding materials. GFG is looking for a Fusion Materials Scientist to work across various aspects of material science. The role connects design, Materials properties, Materials Concepts, manufacturing, and supply-chain work, in collaboration with industrial partners, universities and national and international laboratories. The successful candidate will support Gauss Fusion's current and planned materials portfolio, including low-activation steels, first-wall and blanket interfaces, SiC-based materials, shielding materials, breeder-material lifecycles and irradiation-relevant qualification. Assignments may include activities along a broad range of Projects, according to active priorities and approved project scopes. ### Main responsibilities - Translate plant and component functions, load cases, interfaces, safety requirements and lifetime targets into materials requirements and acceptance criteria - Lead materials activities across metals, ceramics, composites, coatings, joints, breeder materials and shielding materials - Define qualification strategies and phased test programmes from material screening and coupons to representative mock-ups and components - Plan and review chemical, microstructural, mechanical and thermophysical characterization, including corrosion and compatibility, permeation, fatigue, thermal cycling, high-heat-flux and irradiation-relevant testing as applicable - Assess degradation and failure mechanisms and translate test evidence into design decisions, operating limits and lifetime assessments - Provide materials input to mechanical design, manufacturing routes, joining and coating development, neutronics and activation, tritium management and nuclear-safety activities - Define specimen matrices, test protocols, data-quality requirements, uncertainty treatment, traceability and technical acceptance criteria - Develop materials specifications, databases and qualification evidence, and support code-entry and licensing-readiness roadmaps - Review supplier and partner deliverables, facilities, process genealogy, quality records and non-destructive examination plans - Coordinate technical interfaces, deliverables, risks and decisions across research projects and support the preparation of work packages, proposals and technical reports - Evaluate industrial scale-up, supply-chain resilience, recycling and end-of-life implications for fusion-relevant materials - Work with Quality, Nuclear Safety and Export Control experts where materials, data or technologies require controlled handling, and attend activities at partner and supplier premises. ### Qualification and educational requirements - A master's degree or PhD in materials science, metallurgy, materials engineering, solid-state physics, nuclear engineering or a closely related field - Technical experience: - At least 5 years of relevant experience in materials research, development or qualification, preferably in fusion, nuclear, aerospace, energy or another safety-relevant industry - Strong expertise in at least two relevant material classes or technologies, such as reduced-activation or 9Cr steels, stainless steels, tungsten and refractory metals, ceramics or composites, coatings, diffusion barriers, joints, breeder materials or shielding materials - Hands-on experience with materials characterization and testing, such as microscopy, chemical and phase analysis, mechanical testing, fracture or fatigue, thermophysical measurements, corrosion or environmental exposure - Experience defining test matrices and qualification evidence under a quality-management system, with controlled data, specimen and process traceability - Sound understanding of material degradation under high temperature, cyclic loads, irradiation, transmutation, corrosion or hydrogen-isotope exposure; direct fusion experience is preferred but not mandatory - Ability to interpret and apply relevant material, pressure-equipment or nuclear design and qualification standards, for example EN standards, ASTM, ASME BPVC or RCC-MRx - Experience coordinating technical work with research institutes, testing facilities, manufacturers or suppliers and producing reviewable technical documentation ### Competences and preferred skills - Strong understanding of process-structure-property-performance relationships and how they affect component design and qualification - Ability to analyse incomplete or conflicting materials data, quantify uncertainty and make clear, evidence-based recommendations - Familiarity with materials databases, statistical analysis or computational materials and lifetime-modelling tools is an advantage - Experience working with industrial suppliers and research partners on technical scope, test plans and deliverables - Strong analytical and problem-solving skills with a practical approach to experimental planning - Clear technical writing, documentation and presentation skills - Excellent communication and interpersonal skills - Ability to work effectively in cross-functional teams spanning design, neutronics, manufacturing, quality, safety and commercial functions - Familiarity with magnetic fusion, fission or other nuclear systems is preferred but not mandatory - Proficiency in English; the ability to communicate in German and/or French is preferred --- Data: alder (https://alderhq.app).
