Top Tech Jobs & Startup Jobs in Chicago, IL

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.

Design and lay out PWBs/PCBs, flex and rigid-flex circuits using Cadence Allegro. Calculate layer stack-ups, generate fabrication data, ensure manufacturability, interface with electrical/mechanical teams, incorporate change notices, and lead design reviews with quality and manufacturing.

Design and develop space-qualified power conversion systems: architecture, schematic capture, component selection, PCB layout, simulation, lab verification, WCCA, manufacturing support, test procedure development, and lead engineering teams through integration and qualification.

Lead and execute overall systems engineering for EOIR/RFEW defense programs. Ensure engineering process integrity, direct technical teams, decompose requirements, manage integration and verification, create system models and traceability, present technical status to leadership, and maintain required security clearance and on‑site presence.

Develop and direct system-level test plans, procedures, and schedules for space hardware; coordinate integrated testing and calibration activities; manage calibrated equipment records and shipping; support sanitization and security/transportation plans; travel up to 25%.

Provide PCB producibility and design-for-manufacturing expertise across RF, digital, mixed-signal, and power boards. Define stack-ups, impedance, and DFM/DFF rules; run automated DFM tools; generate fabrication data; support suppliers and internal teams; troubleshoot manufacturing issues; and collaborate on sourcing and supplier readiness.

Develop, integrate, test and analyze complex mission and system models in virtual environments. Create simulation code and scripts, document assumptions, automate tests, execute integration test activities, and perform system-of-systems and agent-based operational analysis. Apply knowledge of EOIR, optics, RF, detection and tracking.

Lead systems engineering for mission modeling and virtual system integration. Develop and validate simulation code, system models, and test automation. Perform operational analysis and mission-level modeling (agent-based/System-of-Systems). Guide IPTs, execute integration/test in virtual environments or SILs, and apply EOIR, RF, detection/tracking expertise.

Develop, integrate, test and analyze complex virtual system and mission models for EOIR, RF, and electronic warfare systems. Create simulation code/scripts, design system models, document assumptions, automate tests, run integration activities in virtual environments or labs, and perform mission-level operational analysis using system-of-systems and agent-based simulation.

Leads development, configuration, integration, implementation, testing, and sustainment of enterprise ERP capabilities supporting Maintenance, Repair, and Overhaul operations. Oversees integrations among MES, SAP S/4 Service Management, iMRO, and related systems; troubleshoots interfaces; improves business processes; translates user requirements into technical solutions; supports SAP configuration; documents workflows and data maps; and provides executive status updates.
