Job Summary

Description

Infleqtionis a leader in atom-based quantum technology - the most scalable and commerciallyviableplatform for quantum. We develop quantum information processing systems precision timekeeping and quantum sensing solutions.

With offices inLouisville CO; Madison WI; Chicago IL; Oxford UK; and Melbourne AU weoperateglobally to drive innovation in quantum technology.

As a deep-tech startupInfleqtionembraces a results-driven fast-paced and customer-focused approach to innovation. We seek an experienced Staff Systems Engineer to support multidisciplinary government and commercial R&D projects within our Emerging Technologies portfolio. This role will initially provide critical systems engineering ownership for our Quantum Gravity Gradiometer pathfinder program with NASA while helpingestablishrepeatable systems engineering practices for future RESPONSIBILITIES

The duties and responsibilities below describe the expected scope of ownership. Depending on business needs this role may perform a combination of some orall ofthe following duties;additionalduties may arise.

  • Own and manage system requirements for the Quantum Gravity Gradiometer program including customer-facing requirement cleanup internal requirement decomposition requirements traceability and alignment across engineering teams.
  • 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 and manage interface control documentation (ICDs) including source-of-truth documentation revision control and coordination of interfaces across the sensor head electronics/subcontractor laser laser electronics command and telemetry software and customer teams.
  • Lead verification and validation planning by mapping requirements to verification methods defining evidence needs coordinating test-plan inputs and ensuring customer-facing V&V documentation is complete consistent and review-ready.
  • Coordinate with AI&T leads and technical teams to define document and oversee integration and test activities at multiple assembly levels including capturing test data and packaging results for internal and customer review.
  • Own customer-facing systems engineering documentation quality including document templates folder structure SharePoint organization revision control release status and document readiness before external delivery.
  • Author major systems engineering documents and assign technical sections to subject-matter experts as needed including requirements documents ICDs architecture documents CONOPs verification plans test plans review packages and customer deliverables.
  • Drive Product Life Cycle (PLC) execution for selected R&D and pathfinder programs by defining required deliverables selecting review entry and exit criteria preparing design-review packages and tracking review closure actions.
  • Work with the Chief Engineer andprogramleadership toestablisha repeatable design-review structure including standard review slide decks review expectationsrequiredartifacts action-item tracking and customer-facing closure evidence.
  • Maintain the program risk register and support risk communication with program management and customers including risk retirement plans mitigation owners schedule impacts and linkage to technical decisions.
  • Support andmaintainFMEA or similar failure-analysis documentation ensuring identified failure modes are connected to requirements design mitigations test coverage and program risks.
  • Own non-physics CONOPs documentation by working with physicists subsystem leads and the customer to ensure operations concepts are consistent with system architecture interfaces modes states constraints and expected use cases.
  • Own andmaintainsystem architecture documentation including architecture diagrams subsystem responsibilities functional allocations interface definitions operating modes and change propagation across teams.
  • Own source-of-truthSWaPtracking by collecting updated size weight and power estimates from IPT leads documenting assumptions and margins and communicating impactstoarchitecture requirements risk and customer deliverables.
  • Establish lean right-sized systems engineering processes suitable for deep-tech R&D and early product development without creating unnecessary process burden.
  • Ensure consistent use of systems engineering tools and methods across selected programs includingrequirementsmanagement configuration control document control review readiness traceability and change management.


Requirements

REQUIRED QUALIFICATIONS

  • Bachelors degree in engineering science physics ora relatedtechnical field.
  • 5 years of progressive systems engineering experience with complex hardware/software systems ideally including quantum systems precision sensors aerospace systems spacecraft payloads or other 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 enough technical depth in complex physics hardware electronics software and integration/test systems to drive practical systems engineering decisions and keep teams aligned.
  • Demonstrated ability to work with engineers physicists program managers customers and subcontractors in a fast-paced matrixed environment.
  • Professional-level written verbal and presentation skills including the ability to turn incomplete technical inputs into clear customer-facing documentation.

PREFERRED QUALIFICATIONS

  • Hands-on experience with Jama DOORSPolarion or comparablerequirementsmanagement 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 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 CONOPsSWaPbudgets or interface documentation for systems involving sensors lasers electronics software controls or telemetry.
