- Support the design and assessment of control rooms, command-and-control environments, operator consoles,



and other complex human-system interfaces.
- Develop and execute scenario-based evaluations and validation activities.
- Identify human-performance risks and support the definition of design requirements and mitigation measures.
- Contribute to system requirements development, allocation, traceability, and verification.
- Prepare and maintain controlled engineering deliverables, technical reports, assessment records, and supporting evidence.
- Participate in technical reviews such as Preliminary Design Reviews, Intermediate Design Reviews, Final Design Reviews, safety reviews, and customer review cycles.
- Facilitate multidisciplinary workshops involving systems engineering, safety, operations, software, hardware, design, and customer representatives.
- Review customer and stakeholder comments and support resolution and closure of technical actions.
- Support compliance assessments against applicable Human Factors, ergonomics, safety, and engineering standards.

Required Qualifications

- Minimum 5 years of professional experience in Human Factors Engineering, ergonomics, human-system integration, or a related discipline.
