Head of Fusion Science

Renaissance Fusion is the first Magnetic Confinement Fusion company in the EU.

We are building the first net-energy producing stellarator by combining proprietary innovations in the manufacturing of next-generation High-Temperature Superconducting (HTS) magnets and liquid metal (LM) walls.

In addition, these technologies can find applications in several other industries, including medical imaging, energy storage and“big science”. We are forming a team of the smartest, most driven engineers and business persons to realize and commercialize our non-fusion products within 2 years and our fusion solutions within 10 years.

What we are looking for:

We are forming a team of the brightest, most driven scientists and engineers to realize and commercialize non-fusion HTS magnets and Liquid Metal (LM) solutions within 2 years, and fusion magnets and integrated fusion solutions within 10 years.

Five technical leaders will be at the forefront of this exhilarating development and prototyping. With the present we seek an energetic and energizing (pun intended 😉), goal-driven theoretical fusion plasma physicist with at least 10 years of post-doctoral experience to lead our Fusion Science department. We have a vision for the high-field stellarator power-plant of the future: simple, compact, efficient. This leader and the science department will proactively and responsively provide the engineering departments with the physical input and specifications to design and build the best, physically sound, robust stellarator possible. The ideal candidate has over 30 journal publications but is allergic to incremental results; hungers for disruptive results (but not plasma disruptions) and, indeed, broke new ground in quite a few of them -things that people remember and still use, not 4th order corrections. The ideal candidate is versed in numerical methods and is not OK with the solutions just “existing and being unique”; he/she finds them, quantitatively -and has the physical insight to vet them. He/she specialized in 2-3 sub-fields but is curious and knowledgeable in fusion theory in general, and already led with ability and success a group or department. The ideal candidate has exceptional physical intuition, 3D visualization and problem-solving skills. He/she develops theories that translate in buildable stuff; is abreast with experiments and inspired, provoked by them. The ideal candidate is focused, drives teams to success and is 200% committed to our mission of “bringing fusion energy out of the lab and onto the grid” in the 2030’s. Elegance and simplicity are a plus.

The Head of Fusion Science will work closely with the CTO, the Head of HTS Film Deposition, the Head of Magnets, Vessel & Cryostat (MVC) Engineering, the Head of Liquid Metal R&D and Head of Heat, Diagnostics and Shielding.

Our team is young, agile, international, and based in the exciting city of Grenoble, by the French Alps.


Responsibilities as a leader:

  •  Lead the Fusion Science department

  • Talent Acquisition, Growth & Retention

    • Grow department to 7 members in first 4 months. Play a major role in writing job descriptions and conducting job interviews. Proactively scout and attract talents.

    • Attract top 5% of MS students, PhD students and post-docs from national and international universities for 6 month – 3 year projects.

    • Oversee the formation of two groups in charge respectively of Burning Plasma Physics [alpha particle losses, Alfvén eigenmodes, control of He ashes and impurities, ignition etc.] and Optimization [of the plasma equilibrium, the Coil Winding Surface (CWS) and its “grooves”].

    • Appoint, empower, inspire and coordinate the group-leaders. Train the group-leaders of tomorrow.

  • Scientific leadership and service

    • Timely provide input, answers, and recommendations to engineering -based on the information available- to build the best stellarator possible.

    • Proactively and responsively enact calculations relevant to Renaissance Fusion (RF) mission.

    • Propose and help realizing and analyzing experiments on existing fusion devices and future RF devices to test predictions relevant to RF mission.

    • Doer/manager. At your level of responsibility, you will mostly be a leader and a manager, but we expect you to lead by example and not lose contact with your older self, when you were a great doer. That is, we expect you to walk around the desks and occasionally contribute -in person- to tough theory and modeling questions that colleagues might struggle with.

  • Scientific input to company strategy

    • Identify scientific needs, directions, priorities and goals in the short, medium and long term, to realize the company’s mission and vision of building and commercializing a stellarator power-plant.

    • Identify “gaps” in company’s know-how and skills and fill them as appropriate. Remedies include: reallocation of resources, new hires or outsourcing to external collaborators or providers.

    • Identifies scientific risks and opportunities and spearheads the team efforts to address them.

  • Culture

    • Promote a culture of collaboration, innovation and creativity.

    • Inspire, motivate and guide team to deliver outstanding results that serve and accelerate the company mission.

    • Spark and coordinate mission-driven brainstorm discussions, as needed. Contribute to them and to their rapid convergence to actionable decisions and simulations.

  • Scientific communication

    • Organize the department’s attendance of scientific conferences and workshops with the objective of presenting the department’s results, receiving feedback, learning about external developments and opportunities, and fostering new collaborations.

    • Ensure the publication and dissemination of scientific results.

    • Answer scientific questions and concerns posed by the investors, the media and other stakeholders, in collaboration with communication specialist.

    • Supervise the preparation of internal documentation of computer codes.

    • Lead the department to papers and patents aligned with the RF mission and schedule.

  • Management

Responsibilities w.r.t. to other stakeholders

  • Receive/give feedback from/to team members.

  • Work closely with:

    • The CTO

    • The Head of HTS film deposition, for example on optimal CWS “grooves” that account for the physics of super-currents (following the path of minimum energy, not of minimum resistance, as resistance is zero).
