Infleqtion is a global quantum technology company building quantum computers, sensors, and networks to solve complex problems. We are seeking an experienced Staff Systems Engineer to own systems engineering for Time & Frequency products and programs, working across multidisciplinary government and commercial R&D projects.
You will own and manage system requirements from customer intent through internal decomposition, traceability, and verification planning. Key responsibilities include:
• Maintain requirements-management tools (Jama or equivalent) as the source of truth for customer requirements, derived requirements, verification methods, and change history.
• Own interface control documentation (ICDs) across physics, lasers/optics, electronics, FPGA/firmware, software, mechanical, thermal, command-and-telemetry, and customer teams.
• Lead verification and validation planning by mapping requirements to verification methods, defining evidence needs, coordinating test plans, and ensuring customer-facing V&V documentation is complete and review-ready.
• Coordinate with AI&T leads and technical teams to define, document, and oversee integration and test activities from subsystem through full-system level, including performance data capture and results preparation.
• Own quality and readiness of customer-facing systems-engineering documentation, including templates, folder structure, revision control, and delivery readiness.
• Author major systems-engineering documents (requirements, ICDs, architecture, CONOPs, verification plans, test plans, design-review packages) and assign technical sections to subject-matter experts.
• Drive Product Lifecycle execution for R&D, product-development, and customer programs by defining deliverables, establishing review criteria, preparing design-review packages, and tracking closure actions.
• Work with Chief Engineer and program leadership to establish repeatable design-review structures with standard materials, required artifacts, and action-item tracking.
• Maintain program risk registers and support risk communication with program management and customers, including mitigation plans and schedule impacts.
• Support and maintain FMEA documentation, connecting failure modes to requirements, design mitigations, test coverage, and program risks.
• Own system CONOPs by working with physicists, subsystem leads, applications engineering, and customers to ensure operational concepts align with system architecture, interfaces, and intended use cases.
• Own system architecture documentation for precision timing products, including functional allocations, subsystem responsibilities, timing/frequency-reference architecture, and change propagation.
• Own SWaP (size, weight, power, thermal, environmental) tracking by collecting estimates from IPT leads, documenting assumptions and margins, and communicating impacts.
• Establish lean, right-sized systems-engineering processes suitable for deep-tech R&D and product development without unnecessary process burden.
• Ensure consistent use of systems-engineering tools and methods across programs, including requirements management, configuration control, document control, traceability, and change management.
Requirements:
• Bachelor's degree in engineering, science, physics, or related technical field.
• 5+ years of progressive systems engineering experience with complex hardware/software systems, ideally including quantum systems, precision sensors, aerospace systems, spacecraft payloads, or multidisciplinary R&D systems.
• Demonstrated ability to own requirements from customer-level intent through internal decomposition, traceability, change control, and verification planning.
• Experience developing or maintaining ICDs across electrical, mechanical, optical, software, command/telemetry, and customer interfaces.
• Experience creating V&V plans, test plans, verification matrices, and customer-ready evidence packages for complex technical systems.
• Experience with configuration management, document control, revision control, and formal technical review processes.
• Ability to learn technical depth in complex physics, hardware, electronics, software, and integration/test systems to drive practical systems engineering decisions.
• Demonstrated ability to work with engineers, physicists, program managers, customers, and subcontractors in fast-paced, matrixed environments.
• Professional-level written, verbal, and presentation skills, including ability to turn incomplete technical inputs into clear customer-facing documentation.
Preferred Skills:
• Hands-on experience with Jama, DOORS, Polarion, or comparable requirements management and traceability tools.
• Experience supporting government-funded R&D, NASA programs, aerospace payload development, or customer-facing technical reviews (SRR, PDR, CDR, TRR, or equivalent).
• Experience managing FMEA, risk registers, action-item logs, design-review artifacts, or technical decision records.
• Experience with AI&T, hardware bring-up, subsystem integration, environmental testing, qualification planning, or test readiness reviews.
• Experience owning architecture diagrams, CONOPs, SWaP budgets, or interface documentation for systems involving sensors, lasers, electronics, software, controls, or telemetry.
• Experience helping organizations implement lean Product Life Cycle or productization processes for R&D-to-product transition.
