Human Systems Integration and Human Factors Engineering

OII is in search of a Human Systems Integration (HSI)/Human Factors Engineer (HFE) to support recently awarded programs.  The HSI/HFE Engineer leads and executes human-centered activities across the seven (7) HSI domains - Human Factors Engineering (HFE), Manpower, Personnel, Training, Habitability, Survivability, and Environmental Safety & Occupational Health (ESOH). The role integrates human requirements into systems engineering (SE) baselines, ensuring the system is usable, safe, survivable, supportable, and cost-effective, consistent with DoD HSI policy and standards (e.g., DoDI 5000-series, MIL STD 1472H, and MIL STD 882E). The engineer collaborates across IPTs, program offices, end users, and test communities to plan, analyze, design, verify, and validate human-centered requirements and solutions.

The Staff HSI/HFE Systems Engineer applies working knowledge of systems engineering fundamentals for both unmanned remotely operated vehicles (ROVs) and manned submersible systems to provide guidance to the division’s engineering and design activities under the direction of a program manager and lead engineer. The Staff HSI/HFE Systems Engineer will be required to interact with other OTECH personnel and guides engineering efforts to meet the client’s requirements. The Staff HSI/HFE Systems Engineer will provide guidance to engineering design efforts, with a focus on Human Systems, through the development of systems engineering documentation, including concepts of operations (CONOPS), operational scenarios and vignettes, requirements specifications, interface control documents and drawings, task and workload analyses, and participation in the development of human-centric test plans and procedures. 

The candidate for this position will at a minimum have the responsibility to perform but could also be asked to lead in each of the seven established domains of HSI, as follows:

1) Human Factors Engineering (HFE)

• Derive, allocate, and trace human engineering requirements to system, subsystem, and interface levels; develop HFE specifications using MIL‑STD‑1472H and MIL‑HDBK‑46855A.
• Plan and execute user research (context-of-use analyses, task/functional analyses, workload, situation awareness), human-in-the-loop (HITL) evaluations, and usability testing using formative and summative methods.
• Conduct cognitive and physical ergonomics analyses (e.g., anthropometry, reach envelopes, biomechanics, vision/hearing, control/display design, alerting, and crew station layout).
• Familiarity with both hardware and software GUIs (Graphical User Interfaces) and UX (User Experience)/UI (User Interface) will be needed
• Perform human performance modeling (e.g., timeline analysis, workload assessments, and error analysis) to inform system architecture and risk mitigations.
• Generate Human Engineering Program Plan (HEPP), Human View (DoDAF HV) artifacts, and maintain HFE requirements traceability (e.g., in Cradle/DOORS/Jama).

2) Manpower

• Determine manpower requirements from operational concepts and CONOPS, aligning with affordability and readiness goals.
• Conduct workload distribution and staffing analyses to minimize/optimize crew size while maintaining mission effectiveness.
• Support organizational design for maintenance and operations, aligning with manpower constraints and doctrine.

3) Personnel

• Define knowledge, skills, abilities, and other characteristics (KSAOs) required for operators and maintainers; ensure personnel specifications match design assumptions.
• Establish selection and qualification criteria; coordinate with service communities on Military Occupational Safety (MOS)/ratings impacts.

Primary References: DoDI 5000.95 (HSI); MIL‑STD‑1472H (personnel attributes considerations).

4) Training

• Derive training requirements and conduct Front-End Analysis and job/task analysis to determine training system content and media (live, virtual, and/or constructive).
• Specify training device fidelity and interfaces; support embedded training and performance support in the operational system.
• Develop Training System Requirements Analysis (TSRA), training effectiveness evaluations, and acceptance criteria.

5) Environmental, Safety & Occupational Health (ESOH)

• Perform human-centered hazard analyses and integrate mitigations consistent with MIL‑STD‑882E (System Safety) and MIL-STD-1472.
• Assess environmental and occupational health risks (e.g., noise, vibration, thermal stress, acceleration, and chemicals), coordinating with industrial hygiene and medical communities.
• Support System Safety Program Plan (SSPP), HF hazard logs, and ALARP risk acceptance.

6) Habitability

• Define and verify living/working conditions (e.g., space, lighting, thermal comfort, noise, sanitation, privacy, berthing, and food service) for sustained operations.
• Ensure habitability provisions meet mission duration and environmental requirements (shipboard, land, and/or air).

Primary References: MIL‑STD‑1472H (habitability and environmental design); service-unique habitability criteria (e.g., NAVSEA/ABS references where applicable).

7) Survivability (Human Survivability)

• Analyze crew protection (e.g., ballistic, blast, CBRN, crashworthiness, and egress) and mission continuation under threat; influence layout and materials to protect personnel.
• Integrate warning systems, situational awareness, and procedural and training mitigations.
