Top Tech Jobs & Startup Jobs

Design, analyze, integrate, test, and document mechanical hardware and systems using 3D CAD. Support prototype build, supplier DFM, fielded SIGINT system maintenance, and multidisciplinary system integration with up to 10% CONUS travel. Role may be filled at Mechanical Engineer or Principal Mechanical Engineer levels.

Lead cross‑IPT systems engineering for defense programs: perform functional and timeline analysis, requirements allocation (DOORS), develop architectures in Cameo, integrate models (MBSE/SysML/UPDM), run lab integration and resolve issues, support reviews and capture, and produce technical artifacts while maintaining SAP access and an active Secret clearance.

Develop and sustain mission-operational software product lines and new capabilities for satellite/space systems. Build scalable backend services, design REST/GraphQL/gRPC APIs, work across subsystem teams in Agile, and support DevOps/DevSecOps pipelines for national security programs requiring cleared personnel.

Perform systems engineering tasks including requirements analysis and allocation, architecture development with Cameo, model-based engineering (MBSE), integration and lab testing, DOORS requirements management, cross‑IPT coordination, trade studies, and presenting technical findings at reviews.

Lead cross-IPT systems engineering activities including functional analysis, architecture development, requirements allocation, interface definition, and integration. Develop MBSE artifacts with Cameo and DOORS, support ERBs and program reviews, perform lab integration and troubleshooting, and produce technical documentation. Provide capture and contract support and drive model-based processes, tool integration, and systems-level trade studies.

Lead cross‑IPT systems engineering: perform functional and timeline analysis, requirements allocation in DOORS, develop architectures in Cameo, support integration and lab activities, resolve integration issues, participate in reviews, and produce technical artifacts for large defense programs.

Develop and sustain mission-critical operational software product lines, build scalable backend systems and APIs (REST/GraphQL/gRPC), work in Agile teams using Atlassian tools, and deliver solutions supporting national security spacecraft and ground systems.

Design, develop, test, and integrate embedded software and firmware for defense systems. Work across the full software development lifecycle using C++ and scripting, collaborate with customers and teams, and apply software architecture and embedded OS concepts. Role is full-time, on-site in Rolling Meadows, IL, and requires obtaining a Secret clearance.

Design and maintain end-to-end computer system architectures for defense programs. Integrate emerging technologies, implement engineering changes, configure networks, apply STIGs, support labs, and coordinate with peers and government engineers. Full on-site role with occasional travel.

Support Sentinel program MBSE activities by maintaining authoritative sources of truth (Cameo, DOORS), troubleshooting model health, performing integrations/patches, following configuration control, developing Cameo modeling skills, and documenting processes.
