Laboratory Engineer – Materials Characterisation & R&D

WHO WE ARE Proxima Fusion is Europe’s fastest-growing fusion company and the continent’s best-funded fusion player, as well as the first spin-out from the Max Planck Institute for Plasma Physics (IPP). Backed by over €650M and powered by a growing team across Munich, Zurich, and Oxford, we are developing the hardware and infrastructure needed to deliver the world’s first commercial stellarator fusion power plant. Our concept advances the most mature fusion technology out there, the Wendelstein 7-X stellarator, through two next-generation machines: Alpha and Stellaris. Our work combines stellarator optimization, advanced computation, machine learning, and high-temperature superconducting magnets to unlock higher-performance designs that were previously out of reach. Turning these designs into a functioning fusion power plant requires excellence and ownership across every discipline, from physics and engineering to software, manufacturing, law, and business functions. TEAM AND ROLE * Architect a breakthrough energy technology – Play a defining role in designing and integrating the systems that will power the world’s first commercial stellarator fusion plant, influencing decisions that shape the future of clean energy. * Solve some of the most complex engineering challenges in fusion – Work across magnet design, HTS technology, manufacturing, structural integration, and controls, turning cutting-edge science into real hardware * Move fast and build what matters – Join a highly ambitious, multidisciplinary team that combines cutting-edge simulation with hands-on engineering, turning bold ideas into real hardware on the path to commercial fusion. WHY JOIN PROXIMA FUSION * You will get to work on some of the most complex tech challenges to bring abundant, safe, clean energy to the world. * You'll get to join and learn from an exceptional selection of accomplished and driven individuals. * Do your life’s best work and enjoy the journey. * Get to show that big things are possible in Europe when you assemble the best talent. YOUR IMPACT You will contribute to the development of joint and cable technologies for Proxima’s magnet programme, with a strong focus on hands-on prototyping, manufacturing, and testing at our labs based in Villigen and Böttstein. You will play a key role in the design, fabrication, and iterative improvement of joints, cables, and other related components for magnet prototypes and future HTS magnets. You will operate at the interface between mechanical, electrical, and experimental domains, contributing to rapid prototyping cycles and integration of components into experimental setups. WHAT YOU WILL DO * Design and develop mechanical and electro-mechanical components related to joint and busbar systems * Design and implement early concepts of superconducting cables * Build, assemble, and test prototypes in close collaboration with the workshop * Support manufacturing and integration of components into magnet prototypes and experimental setups * Iterate on designs based on test results, measurements, and experimental feedback * Contribute to the development of manufacturing processes and tooling for joint fabrication * Participate in experimental activities, including setup, instrumentation, and data acquisition * Collaborate with engineers and technicians across mechanical, electrical, and materials domains WHO YOU ARE * Degree in Mechanical Engineering, Mechatronics, Electrical Engineering, or related field * Strong hands-on experience in prototyping, manufacturing, or experimental work * Experience with CAD tools (ideally CATIA; experience with NX, SolidWorks, or Onshape also relevant) * Good understanding of electrical or electromagnetic systems (e.g. current flow, resistive losses, basic circuit behavior) * Comfortable working in a workshop and laboratory environment * Pragmatic, solution-oriented mindset with ability to iterate quickly * Strong team player, able to work across disciplines NICE TO HAVE * Experience with electromechanical systems, sensors, or instrumentation * Familiarity with manufacturing processes (machining, assembly, soldering, etc.) * Experience in R&D or prototype development environments * Exposure to thermal, electrical, or materials characterization INTERVIEW PROCESS * Recruiter Interview (30-60 min) * Technical Screening (30 min) * Technical Panel (2x60 min) * Practical On-site *This role sits at L2 of our framework, please inquire during the recruitment process for further information. At Proxima Fusion, our mission is bold: making limitless clean energy a reality. To get there, we need a high-performing, diverse team that brings different perspectives, challenges assumptions, and builds together with purpose. We know that diversity of thought and experience leads to better ideas, stronger execution, and a more resilient team. We don’t look at how you identify, what you look like, who you choose to worship or what ethnicity you are. We care about what you can bring to the table.

Do you feel most at home in the lab? Are you fascinated by how materials behave, motivated by designing experiments, and driven to understand why one device succeeds while another fails? If that sounds like your kind of challenge, we would love to hear from you! About Epishine Epishine is a Swedish energy impact company, reimagining the capture of light with market leading printed organic solar cells. Our technology captures indoor light to make electronics self-powered, making cables, disposable batteries and unnecessary maintenance a thing of the past. At Epishine, we foster a culture of collaboration, creativity and innovation where we encourage our employees to challenge the status quo and drive innovation. Our company is now growing and we are looking for more driven talents who want to grow and develop together with us! Go to www.epishine.com to read more about Epishine and our vision. The mission As an R&D Engineer at Epishine, you will be spending most of your time in our laboratory fabricating, testing, and evaluating printed organic solar cells. Your primary focus will be experimental work: planning and executing experiments, characterizing device performance, investigating failure modes, and generating high-quality experimental data that helps us better understand and continuously improve our technology. You will start by learning our materials, processes and device architecture while supporting experimental work alongside experienced engineers. As your understanding grows, you'll gradually take ownership of experiments - from planning and fabrication to analysis and interpretation of results. The role is based full-time at our headquarters in Linköping, where you will collaborate closely with an international team of R&D engineers, Technical Project Leaders, Laboratory assistants and Phd students. Who are we looking for? We are looking for an analytical, curious, and hands-on engineer who genuinely enjoys working close to materials and understanding what makes them behave the way they do. You are the kind of person who doesn't stop at "it works" - you want to understand why it works. You enjoy diving deep into experimental results, questioning unexpected outcomes, and designing the next experiment to uncover new insights. You have: A Master's degree in Physics, Chemistry, Materials Science, or a related field Relevant work life experience in a similar role Hands-on laboratory experience and a genuine interest in experimental work, materials, and device characterization Strong communication skills and fluency in English Beneficial: Phd in related field Just as importantly, you enjoy sharing ideas with others. You like discussing experimental results, challenging hypotheses, and explaining your reasoning. Whether you are presenting data, reflecting on why an experiment behaved unexpectedly, or brainstorming the next steps with colleagues, you can communicate your technical thinking clearly and contribute to an open, collaborative R&D environment. Finally – you are someone who actually loves spending all day in a lab! Application procedure Does this role sound exciting? Then apply today! We will start going through applications from August. Starting date is flexible, but sooner rather than later. Good to know We use psychometric tests, such as personality and logic assessments, as part of our recruitment process to ensure fairness and objectivity. These tests help us look beyond a CV and understand each candidate’s natural strengths, problem-solving ability, and working style. By using standardized assessments, we create a more equal opportunity for all applicants, reduce bias, and make sure the role is a good match for both the candidate and the team.
