Responsibilities
Integrate the topological qubit platform with Microsoft’s quantum software stack. Define and evolve interfaces between device control/readout, error‑syndrome pipelines, QIR/QDK toolchains, and Azure services
Drive the software architecture and technical roadmap for scale‑up. Lead multi‑year design for control, decoding, and orchestration systems that support progressively larger topological QPUs and higher logical‑qubit counts
Design, implement, integrate, and test major system components. Ship production‑quality services, runtimes, and APIs spanning device orchestration, calibration & tuning automation, data pipelines, observability, and reliability
Use AI every day to go faster and improve quality. Apply Copilot/LLM workflows for design reviews, code generation, test authoring, telemetry triage, and experiment planning; establish team guardrails for responsible AI use in engineering
Lead and mentor. Provide technical guidance, design leadership, and coaching for junior and mid‑career engineers; set high bars for code health, testing, documentation, and design rigor; Champion secure-by-default practices
Champion engineering excellence. Drive secure‑by‑design practices, CI/CD, robust test strategy (simulation‑in‑the‑loop and hardware‑in‑the‑loop), live‑site standards, and measurable quality gates across the stack
Collaborate across disciplines. Work directly with experimentalists, control & readout electronics engineers, quantum architects, and compiler/runtime teams to turn requirements into shipped capabilities
