• Work closely with data scientists from multiple sectors and backgrounds, AI/ML engineers, software engineers, cybersecurity personnel, cloud architects, and mission stakeholders to transition prototypes into operational capabilities.
• Provide technical leadership for architecture reviews, design decisions, engineering standards, and technology-selection activities.
• Evaluate emerging technologies and recommend modernization opportunities involving AI, data fabrics, data meshes, knowledge graphs, vector databases, lakehouse architectures, and distributed computing.
• Diagnose and resolve highly complex technical issues involving data availability, latency, interoperability, security, and system performance.
• Develop technical roadmaps and communicate architectural alternatives, technical risks, tradeoffs, and recommendations to senior government and contractor leadership.
• Mentor engineers and establish engineering practices that improve quality, repeatability, automation, documentation, and delivery velocity.
• Support technical planning, requirements development, acquisition activities, technical evaluations, and government decision-making as required.

Desired Qualifications
