Description
Summary We are seeking a  Principal Systems Engineer to play a critical role in aligning engineering execution with scientific and machine-level progress in the development of large-scale quantum computers. This role sits at the intersection of quantum science, hardware engineering, and control software , with a primary mission to make the system  coherent, buildable, and integrable  as it evolves. Unlike traditional product environments, many system requirements in quantum computing are  discovered through experimentation , not defined upfront. Success in this role requires deep collaboration with scientists, rapid learning, and the ability to introduce structure  only where it accelerates progress . The ideal candidate brings extensive experience building complex hardware–software systems (e.g., aerospace, EVs, robotics, advanced instrumentation) and is motivated to apply systems engineering rigor in a  learning-driven R&D environment , pairing closely with internal quantum experts. This is a  technical leadership role  with broad influence across teams. Authority comes from clarity, usefulness, and trust — not from gatekeeping or heavy process. Core Mission Bridge the gap between  engineering tasks  and  quantum machine milestones Make system architecture, integration status, and technical risk visible and actionable Enable scientists and engineers to move faster together by reducing ambiguity, friction, and rework Help the organization evolve from ad-hoc integration to disciplined, scalable system development — without slowing discovery Responsibilities 1. System Understanding Through Scientific Partnership Work  closely and continuously with quantum scientists  to understand how the machine is actually operated, tuned, and debugged in practice. Spend significant time in the lab, observing experiments and participating in scientific discussions to absorb tacit system knowledge. Treat scientists as  primary system knowledge holders , approaching requirement gathering as a learning and synthesis exercise. Build trust by accurately reflecting scientific intent and constraints in system models, requirements, and architectural decisions. 2. Requirements Co-Evolution & Traceability Facilitate the  co-evolution of system requirements  as the machine progresses: Start with lightweight, provisional requirements Explicitly document uncertainty, assumptions, and open questions Refine requirements as experimental results and understanding improve Translate scientific goals (e.g., performance, stability, operability) into actionable engineering requirements while preserving necessary flexibility. Establish traceability between: machine-level goals subsystem requirements engineering deliverables (e.g., JIRA epics) Ensure engineers understand the  intent  behind requirements, not just the wording. 3. System Architecture & Integration Leadership Develop and maintain a  living system architecture  covering: quantum hardware control electronics and firmware control software and orchestration layers Produce clear, accessible architecture diagrams that reflect reality and evolve with the system. Identify missing architectural elements, poorly defined interfaces, and integration risks early. Lead system-level trade studies and technical decision-making in partnership with engineering and scientific leaders. Ensure architecture reflects machine milestones and not just organizational boundaries. 4. Integration, Test Strategy, and Machine Protection Define and drive a  system integration and test strategy  appropriate for an evolving R&D machine. Help ensure engineering testbeds match machine configurations as closely as possible. Push integration testing upstream so that machines are not used a
