We are looking for an inspiring and dynamic Group leader of HTS (High temperature superconductors) characterization to define the thin film characterization strategy across all deposition stages and supervises daily operations of the HTS characterization team, ensuring the development and application of robust methods to deliver high-quality assessments and support innovation in HTS material.

Responsibilities

• Thin film characterization activities
  • Validate the thin film characterization strategy, oversee and guide advanced characterization activities of HTS thin films using techniques such as X-ray diffraction (XRD), atomic force microscopy (AFM), scanning/transmission electron microscopy (SEM/TEM), X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, electrical transport measurements, and SQUID magnetometry.
  • Ensure accurate evaluation of superconducting properties, including critical current/temperature (Ic/Tc), critical current density (Jc), and magnetic field response.
  • Supervise the development, optimization, and implementation of measurement protocols to assess film thickness, surface morphology, crystalline orientation, grain boundaries, and composition.
  • Review and validate data analysis approaches and ensure scientific rigor in interpretation.
  • Coordinate investigations on the correlation between manufacturing processes (e.g., polishing, CVD, PVD) and HTS film properties, and drive knowledge transfer to upstream teams.
  • Translate microscopic and performance data into actionable insights for process improvement and material optimization.
  • Provide expert support in troubleshooting material-related issues, including defects, strain effects, and interface challenges.
  • Ensure proper maintenance, calibration, and continuous improvement of characterization tools and methodologies to guarantee data reliability and reproducibility.

• Team management
  • Be the ambassador of Renaissance Fusion's vision within his/her team, and promote its culture, values (speed, simplicity, fantastic realism, constructive interference and unified force) and policies.
  • Encourage collaboration at all levels of the organization.
  • Ensure that his/her team is motivated to achieve its objectives.
  • Take an active role in talent development.
  • Comply with and enforce the highest Health, Environment and Safety standards within your team.

• Scientific outcome
  • Coordinate the writing, review and approval of patents and scientific papers.
  • Prepare scientific reports (presentations, posters, etc.) and represent RF to scientific conferences and workshops.
  • Remain on the lookout for any scientific developments in his/her field of expertise.

Ideal profile

Feel free to apply even if you don't meet all the requirements. Superheroes don't exist, but people with passion and talent do!

• Education and professional experience
  • PhD or Master’s degree + equivalent experience in physics, chemical or electrical engineering, material science or related field
  • 8+ years of experience with thin films processing and characterization methods
  • 3+ years of experience as a technical leader/coordinator and/or project management
  • Research experience with multilayer HTS films and fundamentals of superconductivity, as well as previous experience in a start-up is a plus

• Languages
  • Fluent in English (C1/C2).
  • Knowledge (B1 or higher) of French is a plus.

• Technical skills
  • Proficiency in thin-film superconductors (YBCO, Bi-2212, REBCO, etc.) and their characterization
  • Knowledge on HTS device fabrication and deposition methods (CVD, PVD)
  • Proficiency in data analysis tools such as Python, MATLAB, LabVIEW etc.
  • Industrialization of characterization techniques
