Responsibilities

Serve as a technical authority in precise time, time dissemination, and synchronization systems.
Lead technical assessments of timing systems and architectures (e.g., clock ensembles, timing over communications, holdover solutions, network time synchronization).
Develop and mature concepts for resilient timing (multi-source timing architectures, GNSS alternatives, time transfer techniques, time authentication/assurance).
Evaluate timing performance, robustness, and vulnerabilities in complex environments (e.g., contested RF, cyber threats, denied/degraded GNSS).
Provide independent, objective technical advice and trade studies on oscillators and timing approaches for government and critical infrastructure sponsors.
Partner with government sponsors to understand mission needs and translate them into technical roadmaps, R&D priorities, and implementation strategies.
Lead and shape portfolios of work across multiple projects, ensuring technical coherence and alignment with sponsor objectives and MITRE strategic priorities.
Present complex technical topics and recommendations clearly to senior sponsor stakeholders, including non-technical audiences.
Help define standards, best practices, and reference architectures for timing in defense, intelligence, space, and critical infrastructure domains.
Monitor R&D in advanced clock technologies (e.g., microwave and optical atomic clocks, chip-scale atomic clocks, quartz, and MEMS oscillators).
Guide development and evaluation of time transfer and synchronization techniques (e.g., GNSS CV/CP, two-way time transfer, network-based techniques, IEEE 1588/PTP, NTP).
Initiate and direct experimentation, modeling, simulation, and prototype development to demonstrate and assess timing solutions.
Publish results and represent MITRE in external technical communities (conferences, standards bodies, working groups).
Provide technical mentorship and career development for early- and mid-career engineers and scientists in timing, RF, and PNT disciplines.
Promote rigor in systems engineering, verification/validation, and test and evaluation of timing systems.
