About the Role
Fluidstack is building a captive photovoltaic supply chain to power gigawatt-scale AI infrastructure, starting at the cell. The PV Product Engineering team is focused on selecting and developing cell architectures, optimizing efficiency, and establishing a robust supply chain. We are looking for an experienced individual to own the cell architecture selection and technology roadmap, build loss-analysis frameworks, and manage pilot line partnerships and technology transfer.
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 that can be defended to a CEO and a fab partner.
- 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.
Requirements
- 15+ years in silicon PV cell technology.
- At least one cell architecture (TOPCon, HJT, or back-contact) taken from concept to production efficiency targets, with the roadmap owned by you.
- Experience building and defending a full loss budget across recombination, optical, and resistive losses, and closing real gaps to entitlement on a shipping cell.
- Experience leading process transfers from pilot to production, understanding tool matching and yield collapse.
- Published or patented depth in passivation, contacts, or device design.
- Experience directing multi-disciplinary cell R&D teams spanning process, device physics, and characterization, and setting their technical priorities.
- Ability to commit to an efficiency and cost trajectory and defend it under pressure, to a CEO and a fab partner alike.
