Are you the engineer customers want on the call when they ask whether a TFLN PIC can meet their system requirements? At Lightium, we’re pioneering next-generation photonic integrated circuits (PICs) built on thin-film lithium niobate (TFLN), and we’re looking for a Senior Photonics Application Engineer to be the technical face of Lightium from a customer’s first inquiry to the day their design is onboarded and ready for tape-out. You will shape how every new customer experiences Lightium. Position Summary In this role, you’ll join our Commercial Team, reporting to the CRO, and own the pre-sales customer journey: first contact, technical qualification, feasibility assessment, quotation, purchase order, and onboarding. You will turn customer requirements into a credible technical scope, position the right path (MPW, dedicated lot, or production) on our mature O-band and C-band PDK, and make sure each customer starts with a design flow, design rules, and expectations that set them up to succeed. Your work is the bridge between what our customers need and what our R&D and operations teams can deliver. You know what a customer looks for in a foundry because you have been that customer: you have taken designs to tape-out on external PDKs and seen what separates a foundry you can build a product on from one you can’t. Key Responsibilities Pre-Sales Technical Ownership: Act as the first technical contact for inbound and outbound opportunities across telecom, datacom, quantum, defense, AI, and health, from R&D labs to OEMs and hyperscalers. Qualify requirements against our platform (modulator bandwidth, drive voltage, waveguide loss, wavelength band), assess feasibility, and tell customers early and honestly when a requirement does not fit. Own the technical side of every opportunity until the PO is signed. Technical Scope & Quotation: Define the technical scope of each quotation together with Operations and Sales, covering process, test, known good die (KGD) requirements, a
