• Coordinating directly with customer Human Factors representatives to negotiate, interpret, and refine system requirements and ensure proper allocation across software, hardware, and test domains.
• Leading Human Factors contributions to system safety efforts, including hazard analyses, risk reduction strategies, and design mitigations aligned with MIL-STD-882 concepts.
• Owning Human Factors planning activities across program lifecycle phases from concept development through production and sustainment.
• Providing technical direction and mentorship to early career engineers and cross‑functional teammates in Human Factors methods, analyses, and best practices.
• Briefing Human Factors status, risks, and design implications at technical reviews, design gates, and customer engagements.
• Translating complex operational and user requirements into validated human‑centered design inputs for engineering teams.
• Authoring and reviewing high‑visibility internal and customer‑facing deliverables including HFE reports, trade studies, usability assessments, and design recommendations.
• Collaborating across Systems Engineering, Software/Firmware, Electrical, Hardware, and Safety engineering teams to ensure end‑to‑end human system integration.
• Contributing to or leading development of advanced usability evaluations, cognitive task analyses, workload assessments, and human performance modeling approaches, collaborating across multiple disciplines to gain a full understanding of product architecture and design.
• Interfacing with other engineering functions:
  Systems Engineering, Software or Firmware Engineering, Electrical Engineering, Hardware Engineering.
• Travel up to 20%.

• Typically requires a degree in Science, Technology, Engineering, or Mathematics (STEM) and minimum 5 years of prior relevant experience.
• Experience in Human Factors Engineering, Human Systems Integration, or Safety Engineering in complex systems.
• Experience working with hardware and software integrated systems in a development environment.
• Experience performing or leading requirements decomposition, validation, or systems engineering activities.
• U.S. citizenship required and ability to obtain and maintain a U.S. government‑issued security clearance.
• DoD clearance:
  Secret (active and existing).

• Active and transferable Secret security clearance.
• Experience in defense, aerospace, or other safety‑critical regulated environments.
• Experience applying MIL-STD-1472 and MIL-STD-882 concepts in program execution.
• Experience leading or contributing to usability testing, task analysis, workload assessment, or human performance modeling.
• Experience with user‑centered design practices, including wire framing, prototyping, or HMI design collaboration.
• Experience with systems engineering lifecycle processes (e.g., requirements flow‑down, verification & validation).
• Experience influencing cross‑functional teams in design tradeoffs involving human performance, safety, and operational effectiveness.
• Experience coordinating across multiple IPTs and stakeholders.

Salary range: $86,800 – $165,200 USD. The range is a good‑faith estimate representing all experience levels. RTX considers factors such as role, function, responsibilities, work experience, location, education/training, and key skills when extending an offer.
