15+ years in silicon PV cell technology with experience in TOPCon, HJT, or back-contact architectures.
Proven ability to build and defend a full loss budget across recombination, optical, and resistive losses.
Experience leading process transfers from pilot to production, with insights into common pitfalls.
Published or patented expertise in passivation, contacts, or device design.
Demonstrated leadership of multi-disciplinary R&D teams, setting technical priorities effectively.
Ability to commit to and defend efficiency and cost trajectories under pressure.
Bonus: Experience with SunPower/Maxeon, Fraunhofer ISE, or pilot line buildout.
Responsibilities
Own the selection of Fluidstack's cell architecture and defend the technology roadmap.
Build a comprehensive loss-analysis framework for efficiency entitlement across various loss types.
Direct the technical agenda for process, device physics, and characterization teams in collaboration with the PV Cell Engineering Lead.
Scope and manage pilot line partnerships, overseeing technology transfer from pilot to production.
Set procurement specifications for cells and drive co-engineering with suppliers to ensure quality alignment.
Benefits
Commitment to pay equity and transparency.
Full Job Description
The Product Engineering, Photovoltaics (PV) Team
The PV Product Engineering team is building a captive photovoltaic supply chain to power gigawatt-scale AI infrastructure, starting at the cell.
Examples of key problems the team is working on:
Select and commit to a silicon cell architecture (TOPCon, HJT, or back-contact) and the efficiency and cost trajectory that decision locks in for years.
Build the loss-analysis and efficiency entitlement framework that tells every process and device engineer where the next basis point of efficiency comes from.
Stand up pilot line partnerships and a technology transfer path from pilot to production that survives contact with a real fab.
Set cell procurement specs and co-engineer with suppliers so the buildout keeps moving while our own line comes up.
Role Scope
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.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
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.
