Team and Stakeholder Coordination

• Ensure alignment between technical activities (led by the Chief Engineer) and broader program objectives, contract deliverables, and customer expectations.

Risk and Change Management

• Maintain and update the project risk register; proactively identify, assess, and mitigate schedule, funding, or integration risks.
• Manage scope changes and assess impacts on schedule, cost, resources, and contract execution and deliverables.

Budget and Resource Oversight

• Assist in budget planning and monitoring; track obligations, expenditures, and funding profiles in coordination with finance teams.
• Assist with coordinating resource needs and staffing plans to ensure adequate coverage across phases of the project and timely contract execution.

Requirements:

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field (Master's or PhD preferred).
• 5-10 years of experience managing complex technical programs or infrastructure projects, preferably in aerospace, defense, or R&D environments.
• Demonstrated experience in direct execution of deliverables under contract to a government customer.
• Strong understanding of project management best practices (e.g., execution, risk analysis, scheduling, budget planning).
• Familiarity with propulsion test infrastructure, ground test facilities, or aerospace systems integration.
• Experience managing external suppliers and contractors in high-complexity technical environments.
• Excellent written and verbal communication skills; adept at briefing senior leadership and managing multi-stakeholder dynamics.
