Arbeitsbeschreibung - Fusion Materials Scientist

About the role

Materials’ performance and qualification are central to the design of a fusion power plant. 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

About us

Gauss Fusion is a European fusion company focused on industrialising stellarator fusion and developing a modular power plant architecture, critical technologies and industrial capabilities required for scaling fusion power plants in the future.

The start-up was founded in 2022 by Frank Laukien together with European high-tech companies with capabilities in magnetic-confinement fusion and component production for Fusion experiments like ITER. Gauss Fusion combines fusion science and systems engineering with industrial engineering and manufacturing expertise. Its peer-reviewed GIGA™ power-plant platform provides the technologically most promising system-level architecture to build cost-efficient stellarator power plants at scale.

Within this architecture, Gauss Fusion is advancing critical technologies in areas including demountable magnet systems, tritium breeding, fuel-cycle technologies, and plasma exhaust. Working with industrial partners, technology providers and leading research institutions across Europe, the company is building the engineering, technologies and supply-chain capabilities required to progress stellarator fusion towards industrial deployment.

Join us on our journey to revolutionize the energy landscape and make fusion power a reality.
