Jobs at Great Sky

Design and verify superconducting electronic circuits for AI hardware, including Josephson junctions, SQUIDs, superconducting nanowire detectors, and thin-film amplifiers. Adapt circuits for advanced fabrication processes, support electromagnetic and post-layout simulation, develop Python-based layout flows, expand device-primitives libraries, and collaborate with fabrication, foundry, algorithms, and measurement teams to execute successful chip tapeouts.

Design and optimize active and passive photonic components and detector-integrated circuits for cryogenic platforms. Responsibilities include electromagnetic simulation, photonic layout, DRC verification, foundry tapeouts, PDK and component-library development, and collaboration with test, packaging, and systems teams to validate cryogenic performance.

Develops cryogenic photonic and superconducting device fabrication processes from design through prototype production. Responsibilities include cleanroom fabrication, lithography, thin-film deposition, etching, planarization, metrology, yield analysis, root-cause investigation, SOP and process documentation, PDK maintenance, and collaboration with design, test, packaging, and integration teams.

Design and fabricate cryogenic photonic and superconducting devices, including SiN passive components and SNSPDs. Own end-to-end prototyping in cleanroom environments, optimize manufacturing processes, establish SOPs and Processes of Record, maintain PDKs and component libraries, and collaborate with testing, packaging, and systems teams to improve device performance and development cycles.
