Principal Radar Systems Engineer

Systems EngineerSciTec, a wholly owned subsidiary of Firefly Aerospace, is a dynamic non-traditional defense contractor that delivers advanced technologies in support of U.S. National Security and Defense. For the past forty-five plus years, we have supported Department of Defense customers by developing innovative remote sensing algorithms, tools, and techniques to deliver world-class data exploitation capabilities supporting missile defense; intelligence, surveillance, & reconnaissance; space domain awareness; and aircraft survivability missions.SciTec exclusively works on U.S. government contracts that require U.S. citizenship for all employees. SciTec cannot sponsor or assume sponsorship of employee work visas of any type. Further, U.S. citizenship is a requirement to obtain and keep a security clearance. Applicants that do not meet these requirement will not be considered.SciTec is seeking a Systems Engineer to drive end-to-end development and modernization of advanced radar system capabilities. SciTec's radar programs integrate digitized front-end hardware, embedded firmware, high-performance signal-processing software, and cloud-based mission-data services. You will lead cross-functional feature design and implementation, ensuring system-level performance improvements and modernization outcomes that meet mission needs and operational reliability standards.You will collaborate across hardware engineering, embedded software, digital signal processing, DevSecOps pipelines, and mission analytics teams to deliver modern radar capabilities that replace legacy architectures with digital, open, cyber-resilient solutions. Ultimately, you will be responsible for system-level problem solving, requirement development, test and validation strategy, and data-driven analysis that ensures upgraded radar features perform as expected in both test and operational environments.ResponsibilitiesEnd-to-End Ownership: Serve as the primary technical owner for assigned radar modernization features. Understand how digitized radar front-end components, DSP chains, mission-data pipelines, and cloud-based back-ends contribute to overall performance. Lead cross-functional teams, validate and debug integrated system behavior, analyze test and operational data, and clearly report status and risks to leadership.Requirements & Architecture Development: Create detailed, testable system requirements and acceptance criteria for modernized radar capabilities. Decompose high-level mission needs into subsystem requirements for hardware digitization, DSP algorithms, timing/synchronization, interface protocols, data models, and performance tolerances.Data Analysis & Performance Assessment: Conduct Python/SQL analyses on test ranges, simulation outputs, and fielded radar data. Evaluate feature performance against modernization objectives such as digitization fidelity, latency reduction, tracking accuracy, beamforming improvements, interoperability, and system resilience.Integration, Test, and Debug: Oversee integrated testing of modern radar features, including hardware-in-the-loop, simulation-driven validation, digital engineering workflows, and DevSecOps-based software deployment. Debug full-stack radar issues spanning RF data collection, DSP pipelines, message formats, and cloud processing.Planning & Execution: Build and manage the plan for delivering modernization features from concept through customer release. Communicate timeline, scope, risks, and dependencies with engineering and product leadership. Coordinate with internal partners and government stakeholders as required.Other duties as assigned
