A robust network within key DoW organizations, including PEOs, PMs, S&T organizations, Combatant Commands, service research laboratories, and FFRDCs.
Deep technical and domain knowledge and a comprehensive understanding of government funding, program, and procurement processes.
Deep understanding of DoW acquisition pathways, including FAR-based contracts, OTAs, SBIR/STTR, BAAs, consortium-based solicitations, and rapid acquisition frameworks.
Demonstrated success penetrating and influencing large defense programs, shaping requirements and program roadmaps, and positioning emerging technologies for program-of-record pathways.
Strong understanding of national-security mission needs where quantum sensing can provide operational advantage, including EW, PNT, ISR, space, missile defense, advanced sensing, and quantum-based time and frequency solutions.
Ability to operate in early-stage and low-TRL environments, guiding customers through technology maturation, experimentation, and transition to fielding.
Working knowledge of relevant processes and protocols and success collaborating with or within Defense Primes on business development, capture, teaming, and integration strategies.
Strong influence skills with senior uniformed and civilian leadership, including the ability to articulate strategic value to SES, O-6+, and equivalent senior government officials.
