WHAT YOU WILL DO - Own the Talent Acquisition strategy end-to-end, translating our hiring plan — spanning R&D, engineering, and manufacturing — into a concrete, resourced recruiting operation. - Build, lead, and develop a team of recruiters; decide where to hire in-house vs. deploy agencies or RPO support, especially for high-volume manufacturing and shop-floor hiring. - Design and run hiring approaches for two very different worlds at once: high-touch, highly technical recruiting for scientists and engineers, and higher-velocity, structured recruiting for manufacturing technicians, operators, and production roles. - Partner directly with the leadership team and hiring managers across engineering, science, and manufacturing to forecast headcount, define role profiles, and build hiring plans tied to facility ramp-up and program milestones. - Own full-cycle recruitment for the most senior, niche, or business-critical roles yourself, modeling the bar and craft you expect from the team. - Drive top-of-funnel strategy beyond LinkedIn: build sourcing pipelines, talent communities, and employer brand presence in fusion, deep tech, and advanced manufacturing talent pools across Germany and internationally. - Together with the team, set up and manage manufacturing-specific hiring channels (technical schools, apprenticeship pipelines, local labor markets around our facilities,) as we build out production capability. - Own TA metrics and reporting — hire vs headcount ratio, time-to-hire/time-to-fill, pipeline health, quality-of-hire, — and use them to continuously improve how we hire. - Champion an outstanding candidate experience at every touchpoint, from a production technician's first interview to a senior physicist's final panel. - Own strategic TA projects end-to-end — treating each as a leadership deliverable with clear scope, timeline, and success metrics. - Lead and develop the TA team, setting individual and team goals, coaching recruiters on outside-of-the-box sourcing strategies and stakeholder management, and creating a culture of ownership where each person runs their own reqs and projects with real autonomy. WHO YOU ARE Must have - You have led and scaled a Talent Acquisition function, ideally building or growing a TA team from a very early stage to an industrial build-up. - You have direct experience recruiting in both deep-tech or highly technical environments. You have hired in hardware-intensive, engineering-led scale-ups (aerospace, energy, robotics, automotive, semiconductors, or similar), ideally through a phase of significant headcount growth. - You are comfortable building recruiting processes for high-volume, structured hiring (manufacturing, production, technicians) as well as highly bespoke, senior technical searches. - You are hands-on: you're as comfortable running a search yourself as you are managing a team and building a strategy. - You are data-driven and use metrics to diagnose bottlenecks and drive continuous improvement in hiring. - You’re comfortable operating in a scale-up with some level of uncertainty and moving goalposts. Nice to have - You’ve hired and built teams in manufacturing or industrial operations. - You have worked and led TA teams internationally, with some focus on Germany. - German at C1 and above.

YOUR IMPACT You will make Proxima's plasma simulation stack trustworthy by confronting it with reality. Every prediction we make for Alpha – Proxima's Q>1 experimental stellarator – and for Stellaris, our commercial power plant, rests on models whose credibility has to be earned against real measurements from an operating device. W7-X is where we earn it. You will take our integrated modeling framework, FUS3, and our Bayesian plasma state estimation workflow to W7-X data: reconstruct the plasma state from diagnostic measurements, compare our predictive models against what the machine actually did, and turn the discrepancies into a prioritized map of where our physics is right, where it is not, and what we must fix before Alpha's first plasma. Modeling sits on Alpha's operational critical path and cannot be backfilled after first plasma – this role is how we get ahead of it. You will be the person in the group who lives at the intersection of modeling and experiment: fluent enough in the physics to know what a model should predict, and close enough to the diagnostics to know what the data can actually support. WHAT YOU WILL DO - Validate Proxima's predictive plasma models against W7-X experimental data – neoclassical and turbulent transport, 3D equilibrium, ECRH deposition, pellet fueling and drift, bootstrap current and iota evolution – and record each comparison as a reproducible validation report with quantitative agreement metrics, stated limitations, and a pinned regression test - Reconstruct the plasma state from real diagnostic measurements using our time-dependent Bayesian state-estimation workflow (Thomson scattering, interferometry, CXRS, ECE, XICS, bolometry, magnetics), with calibrated uncertainties, and benchmark it against established analyses such as Minerva/IDA reconstructions and ASTRA power-balance results - Work with raw and pre-processed diagnostic data, not just analyzed profiles – instrument geometry, sightlines, calibrations and the caveats that come with them – and own the forward models, noise models and profile fits that feed transport analysis - Validate against databases of discharges rather than single shots, across W7-X magnetic configurations and operating regimes, so the output is a map of model applicability and parameter trends rather than one-off discrepancy reports - Act as a technical interface to W7-X and IPP: scope and prioritize data requests, spend time on site in Greifswald working alongside diagnosticians and operators, and propose and support experiments that directly target our model gaps - Feed validation back into design – convert diagnostic placement and observability studies on W7-X into requirements for Alpha's diagnostic set, and into realistic uncertainty models for the synthetic measurements we use to design against - Extend the modeling stack itself: mappers from experimental archives into IMAS, synthetic diagnostics, and analysis workflows, so that interpreting a shot end-to-end – raw data to reconstructed plasma state to physics quantities – runs in minutes and is reproducible by anyone in the group - As Alpha approaches operation, help stand up the between-shot analysis loop that will run on day one WHO YOU ARE - PhD in plasma physics, fusion science, or a closely related discipline - Hands-on experience with experimental data from a magnetic confinement device – you have dealt with diagnostics, calibrations, systematic errors, and all the ways real data is messier than simulation output - Experience reconstructing the plasma state from measurements: profile fitting, integrated data analysis, equilibrium reconstruction, or power and particle balance analysis - Strong grounding in transport, equilibrium, and heating physics – enough to tell a code bug from a physics discovery - Rigorous about uncertainty; you treat a validation claim without error bars on both sides as incomplete - Comfortable writing and maintaining scientific software – version control, testing, and reproducibility are habits, not overhead - Can communicate effectively with physicists, diagnosticians, engineers, and experimentalists, and work productively inside an external collaboration - Self-directed; able to identify what needs to be done and execute - Willing to travel regularly to Greifswald, and later to the Alpha site NICE TO HAVE - W7-X experience - operations, diagnostics, or data analysis, and familiarity with the W7-X data archive and Minerva - Stellarator physics background - Bayesian inference, uncertainty quantification, or machine learning applied to experimental data - Experience with integrated modeling and transport codes (FUSE, OMFIT, ASTRA, TRANSP, FUSE, JINTRAC, or similar) and with neoclassical (SFINCS, DKES, NEO) or gyrokinetic (GENE, CGYRO, GX, or similar) codes - Julia and Python programming – our integrated modeling framework is written in Julia - Familiarity with the IMAS data model - Familiarity with AI-assisted development tools - A track record of published validation studies or successful experimental proposals INTERVIEW PROCESS - Recruiter Interview (30-60 min) - Technical Screening (30 min) - Technical Panel (3x60 min) At Proxima Fusion, our mission is bold: making limitless clean energy a reality.

YOUR IMPACT In a fusion reactor, fusion-born alpha particles play a central role in plasma self-heating and overall reactor performance. Their confinement, transport, and interaction with collective plasma instabilities directly determine whether a burning plasma can remain stable, efficient, and economically viable. At reactor scale, energetic particle driven Alfvénic activity can enhance fast ion losses, exacerbating plasma loads on the first wall and other in-vessel components. As such, this interaction is critical to include in the design of reactor relevant magnetic configurations and their corresponding operational scenario. As an Burning Plasma Physicist at Proxima, you will lead efforts to understand, model, and optimize energetic particle behavior in reactor-scale stellarator plasmas. Your work will focus on fast-ion confinement, energetic particle transport, and bulk plasma interactions mediated through Alfvénic activity. You will develop and apply advanced numerical tools to assess alpha particle confinement, characterize instability-driven transport, and guide stellarator optimization toward robust burning plasma operation. This role offers a rare opportunity to shape the physics foundations of a commercial stellarator power plant. Your work will directly influence plasma performance, reactor operating limits, and the ability of future devices to achieve reliable steady-state fusion power. By connecting first-principles plasma physics to reactor design decisions, you will help define the path toward practical burning plasma operation in optimized stellarators. WHAT YOU WILL DO - Lead the development, validation, and application of advanced energetic particle transport workflows for assessing burning plasma physics in reactor-scale stellarator plasmas. - Investigate energetic particle driven instabilities, including Alfvén eigenmodes and related EP–MHD interactions, and assess their impact on plasma performance. - Ensure alpha particle confinement remains within the tolerable limits of plasma facing components under reactor-relevant operational scenarios. - Work closely with stellarator optimization teams to incorporate energetic particle physics constraints into magnetic configuration design. - Develop reduced-order models and analysis workflows to accelerate reactor design studies and scenario optimization. WHO YOU ARE - Hold a postgraduate degree in plasma physics, or a related discipline. - Have strong expertise in energetic particle transport, burning plasma physics, or kinetic plasma instabilities. - Bring experience studying EP–MHD interactions, including Alfvén eigenmodes, fast-ion driven instabilities, or related wave-particle interaction physics. - Have experience using advanced simulation tools for kinetic, orbit-following, gyrokinetic, or hybrid MHD modeling. - Be proficient in scientific programming languages such as Python, Julia, C++, and/or Fortran. - Be comfortable working across disciplines, collaborating closely with physicists and engineers to solve open-ended reactor design challenges. - Take initiative, communicate clearly, and be motivated by solving open-ended physics challenges critical to commercial fusion energy.

Mechanical Design Engineer Stellarator Engineering Stellarator Engineering Munich Oxford 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. BY JOINING OUR TEAM YOU’LL GET TO - Shape the architecture of the world’s first commercial fusion power plant – Own system-level decisions that determine how a first-of-a-kind energy technology is designed, integrated, and ultimately deployed at scale. - Solve some of the most complex engineering challenges – Work across tightly coupled disciplines (plasma physics, magnets, cryogenics, manufacturing, controls, and more) to resolve critical trade-offs and turn cutting-edge science into a functioning product. - Design real hardware with a pragmatic, fast-moving team from all over the world – Combine advanced simulation and systems thinking with a strong execution mindset, focusing on practical engineering solutions that accelerate the path to commercial fusion energy.
