Own and maintain system architecture documentation, including architecture diagrams, subsystem responsibilities, functional allocations, interface definitions, operating modes, and change propagation across teams. Own source-of-truth SWaP tracking by collecting updated size, weight, and power estimates from IPT leads, documenting assumptions and margins, and communicating impacts to architecture, 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, including requirements management, configuration control, document control, review readiness, traceability, and change management.Requirements
REQUIRED QUALIFICATIONS
Bachelor's degree in engineering, science, physics, or a 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 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, 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 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.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. Customer-facing materials are technically consistent, controlled, and cleaned up before they leave the company. Changes in requirements, architecture, interfaces, SWaP, or test plans are propagated across the affected teams instead of staying isolated in one subsystem. Systems engineering process improves execution speed and technical clarity rather than adding paperwork for its own sake.Notice to Recruitment Agencies:
