Jobs at C12

Develops 2.5D and 3D integration architectures and advanced packaging for quantum processors. Responsibilities include designing interconnects, interposers, TSVs, micro-bumps, hybrid bonds, chiplet interfaces, and integrating QPUs with cryogenic CMOS, RF, photonics, MEMS, and substrates. Performs electrical, electromagnetic, mechanical, and thermal simulations; defines fabrication processes; develops test vehicles; analyzes measurements; and collaborates across engineering and manufacturing teams.

Design and deploy self-hosted LLM infrastructure and agentic automation across R&D, IT, and operations. Build end-to-end AI workflows, MCP servers and integrations, ensure secure on‑prem deployments, implement observability and iterate on agent performance, and deliver production-ready internal tools.

Operate and improve a custom nano-assembly vacuum setup to transfer carbon nanotubes onto microchips, design and validate experimental protocols, inspect/clean/characterize silicon chips (probe station, SEM), and collaborate with software to improve control software and data storage/analysis.

Lead and grow the operations team to ensure facility and equipment availability for a quantum computing lab. Own preventive maintenance, reliability programs, monitoring dashboards, vendor management, budgets, on-call/shift coverage, safety and incident response, and readiness for new facilities.

Lead design, integration, and validation of RF/microwave systems for quantum hardware. Develop low-noise signal chains from room-temperature to cryogenic, perform EM and noise simulations, characterize components with RF instrumentation, optimize signal integrity and thermal effects, create automated test and calibration procedures, and collaborate across teams while mentoring junior engineers.

Lead and coordinate the Theory & Applications team to define the theory roadmap, drive error-correction strategy, co-design hardware-theory architectures, recruit and mentor the team, and build academic and industrial collaborations to enable scalable, fault-tolerant quantum computing and industrial quantum advantage.
