The role is full-time and on-site in Rolling Meadows, Illinois, with Secret clearance required before starting.

Designs and tests custom algorithms, develops and validates complex models and simulations, and applies systems engineering to physics phenomenology, performance modeling, and targeting, EOIR, and RF systems. Collaborates with engineers and physicists to implement algorithms in products. Requires technical presentations, documentation, and proficiency in MATLAB, Python, and/or C/C++. The role is full-time, on-site in Rolling Meadows, Illinois, with 10% travel and a Secret clearance required for start.

Leads systems engineering, integration, and testing activities for complex defense systems. Directs engineering processes, personnel, requirements decomposition, verification, technical presentations, cost accounts, schedules, and Earned Value Management. Collaborates across hardware, software, and firmware development throughout the lifecycle, from proposal and requirements analysis through testing and fielding. The role is full-time, on-site in Rolling Meadows, Illinois, supports EOIR and RFEW systems, and requires a U.S. Secret clearance and citizenship.

Develops and validates hardware and software security solutions for DoD sensor payloads and mission systems. Responsibilities include systems security architecture, requirements development, anti-tamper and cybersecurity implementation, reverse engineering, security testing, RMF compliance, technical release analysis, exportability assessments, cryptographic protection, A&A documentation, and POA&M maintenance. The role collaborates with government, program, business development, and international stakeholders and provides technology-release training. This is a full-time, on-site position in Rolling Meadows, Illinois.

Develop and integrate hardware and software anti-tamper and cybersecurity solutions for DoD sensor, targeting, and electronic warfare systems. Perform secure architecture, requirements development, security testing, validation, reverse engineering, risk management, technical release analyses, exportability assessments, and compliance with U.S. Government security policies. Support Assessment and Authorization, Security Plans, POA&Ms, technology release training, cryptographic security, and collaboration with government and international program stakeholders.

Design, implement, and test digital hardware and FPGA-based circuit cards across full product lifecycle. Work on high-speed interfaces, RF/EO DSP, embedded processors, prototype/debug subsystems, produce design/test documentation, and support production and fielded systems in an integrated engineering team.

Lead a team of RF/microwave manufacturing test engineers to develop, implement, and troubleshoot microwave test sets and methods for Integrated Microwave Assemblies. Manage programmatic and financial aspects, drive continuous improvement (DMAIC/Lean/Six Sigma), coordinate across functions, and ensure production quality, yield, and schedule for EW systems in a 100% onsite manufacturing environment.

Leads the LITENING Manufacturing Engineering team supporting assembly, alignment, testing, production processes, and continuous improvement. Manages engineering resources, capital projects, capacity planning, equipment and test-station development, proposals, and production support. Provides people leadership, collaborates cross-functionally, and drives manufacturing efficiency, quality, and delivery performance in a fast-paced defense production environment.

Designs electromechanical servo systems, including motor selection, PWM and linear motor drive hardware, controls, testing, troubleshooting, and subsystem integration. The engineer supports multiple programs in a multidisciplinary team and applies power electronics, digital control theory, MATLAB/Simulink, circuit simulation, EMI/EMC, and embedded controller expertise to high-precision motor drive applications.
