Responsibilities

  • We develop quantum information processing systems, precision timekeeping, and quantum sensing solutions.
  • With offices in Louisville, CO; Madison, WI; Chicago, IL; Oxford, UK; and Melbourne, AU, we operate globally to drive innovation in quantum technology.
  • We seek an experienced Staff Systems Engineer to support multidisciplinary government and commercial R&D projects within our Emerging Technologies portfolio.
  • Depending on business needs, this role may perform a combination of some or all of the following duties; additional duties may arise.
  • Maintain Jama or equivalent requirements management tooling as the source of truth for customer requirements, derived requirements, verification methods, requirement status, version control, and change history.
  • Own customer-facing systems engineering documentation quality, including document templates, folder structure, SharePoint organization, revision control, release status, and document readiness before external delivery.
  • Own and maintain system architecture documentation, including architecture diagrams, subsystem responsibilities, functional allocations, interface definitions, operating modes, and change propagation across teams.
  • Ensure consistent use of systems engineering tools and methods across selected programs, including requirements management, configuration control, document control, review readiness, traceability, and change management.
  • 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.

Requirements

  • Bachelor's degree in engineering, science, physics, or a related technical field.
  • 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.
  • Professional-level written, verbal, and presentation skills, including the ability to turn incomplete technical inputs into clear customer-facing documentation.
  • REQUIRED QUALIFICATIONS Bachelor's degree in engineering, science, physics, or a related technical field.

Nice to have

  • 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 such as SRR, PDR, CDR, TRR, or equivalent gate reviews.
  • 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.
  • SUCCESS IN THIS ROLE LOOKS LIKE The program has a clear, maintained source of truth for requirements, interfaces, architecture, SWaP, risks, CONOPs, and V&V status.
  • Engineering teams know what documentation and evidence are required before design reviews and customer deliveries.
  • Changes in requirements, architecture, interfaces, SWaP, or test plans are propagated across the affected teams instead of staying isolated in one subsystem.
  • Notice to Recruitment Agencies: Infleqtion does not accept unsolicited resumes from agencies.

Compensation
