About the role

Lead role overseeing Fluidstack's PV cell architecture, loss-budget framework, and pilot-to-production tech transfer for silicon PV cells powering AI infrastructure.

Responsibilities

  • Own the selection of Fluidstack's cell architecture (TOPCon, HJT, or back-contact) and the technology roadmap behind it, with an efficiency and cost trajectory you can defend to a CEO and a fab partner alike.
  • Build the loss-analysis framework and efficiency entitlement model, decomposed across recombination, optical, and resistive losses, rigorous enough that every process and device engineer knows exactly where their next basis point comes from.
  • Direct the technical agenda of the process, device physics, and characterization teams in partnership with the PV Cell Engineering Lead, setting priorities that close real gaps to entitlement.
  • Scope and manage pilot line partnerships, and own the technology transfer strategy from pilot to production, including the make-vs-partner call.
  • Set cell procurement specs and drive supplier co-engineering while our own line comes up, so the cells we buy meet the same bar as the cells we intend to build.

Qualifications

  • 15+ years in silicon PV cell technology, with at least one cell architecture (TOPCon, HJT, or back-contact) taken from concept to production efficiency targets, and the roadmap behind it owned by you.
  • You've built and defended a full loss budget across recombination, optical, and resistive losses, and closed real gaps to entitlement on a shipping cell.
  • You've led process transfers from pilot to production and know firsthand what breaks, from tool matching to yield collapse.
  • You hold published or patented depth in passivation, contacts, or device design.
  • You've directed multi-disciplinary cell R&D teams spanning process, device physics, and characterization, and set their technical priorities.
  • You can commit to an efficiency and cost trajectory and defend it under pressure, to a CEO and a fab partner alike.
  • Bonus: SunPower/Maxeon, Fraunhofer ISE, ISC Konstanz, or UNSW lineage, FEOC-clean supply chain exposure, back-contact architecture depth, or pilot line buildout experience.
