About the role

Key responsibilities & impact

Own end-to-end system architecture: From antenna, to analog components, to integration with software defined radio (SDR) and edge computing hardware, to data transport, to the cloud, and all the interfaces between.
Develop and maintain system design documentation: System requirements specifications, ICDs, architecture descriptions, and future concepts.
Resolve cross-functional technical conflicts, ensuring RF, embedded systems, compute/algorithm, and cloud development efforts are aligned to key design and performance objectives.
Set and refine system technical requirements by evaluating tradeoffs between COTS, modified COTS, and custom developments.
Ensure timing accuracy and synchronization across distributed systems.
Understand best practices in characterizing and managing system-level time and frequency biases.
Manage requirements traceability from customer mission needs through verification and validation.
Lead technical risk identification and mitigation at the system level.
Oversee and define the test and evaluation architecture; ensure lab test infrastructure aligns to greatest system risks to maximize durability and lifespan.

Requirements

What you’ll need

15+ years in systems engineering, RF-centric payload design, or distributed sensor system architecture.
Demonstrated design leadership and ownership with fielded RF sensing systems.
Experience with distributed sensor network architectures: edge compute, multiple transport paths, and cloud-based processing pipelines.
High precision systems: time and frequency bias characterization, calibration methodologies, accuracy budgeting.
Strong systems engineering process discipline: requirements decomposition, ICD development, PDR/CDR ownership.
Experience with SDR and FPGA hardware integration: wideband acquisition, digitization, and digital back-end interfaces.
Active Secret clearance, or demonstrated ability to obtain one.
Experience with systems deployed to harsh operational environments and/or cluttered spectral environments.
Experience technically managing hardware subcontractors and vendors producing customized technical solutions.
