Top Tech Jobs & Startup Jobs in Los Angeles, CA

Design, analyze, and validate GNC algorithms and high-fidelity 3‑DOF/6‑DOF simulations for space vehicles and payloads. Define requirements, perform sensor/actuator selection and trade studies, build verification tools and software, support flight operations, and provide technical leadership for a small GNC team.

Design, simulate, and validate guidance, navigation, and control algorithms and systems for space vehicles and payloads. Develop high-fidelity 3‑DOF/6‑DOF models, perform trade studies for sensors/actuators, implement trackers/filters/controllers, and build software and HIL simulation tools to support flight operations and mission requirements.

Perform accounts receivable and payable for classified programs, process sensitive vendor payments, prepare and submit classified billings, reconcile payables/receivables, monitor cash for government contracts, post journal entries, support audits, and participate in special projects.

Designs and supports mixed Linux and Windows computer systems for space systems testing. Manages network configurations, user accounts, shared drives, and EGSE test set integrations. Provides on-site floor support, troubleshooting, and 24x7 on-call coverage during critical tests. Requires travel (~10%) and active Top Secret/SCI with polygraph.

Lead definition, integration, and verification of external system interfaces across space and ground segments. Own and baseline ICDs/IRDs, decompose requirements, coordinate mechanical/electrical/data/RF/software interfaces, support integration/test planning, troubleshoot interface issues, and communicate with customers and program leadership.

Support factory and site integration and test for ground systems: develop and execute system-level test procedures, conduct dry-runs and run-for-records, present at TRRs/TRBs, analyze test data and drive discrepancy resolution, author test/configuration documentation, support hardware/software/network integration, and participate in site installation and verification activities.

Perform systems engineering for communications: architecture trades, design analysis, performance modeling, requirements definition and allocation, hardware development support (antenna/RF/digital), design review and unit verification planning, and analyze test data to verify system metrics using MBSE/DOORS and link analysis techniques.

Design, develop, test, and debug modular, scalable software for secure cross-domain solutions. Modernize and productionize applications using C/C++/C#/Java, implement CI/CD and MLOps pipelines, collaborate with systems, cyber, and hardware engineers, and support installations, upgrades, and maintenance while meeting stringent security requirements.

Support proposal preparation, negotiation, administration, and customer contract activities for aerospace programs. Act as primary customer contract interface, manage contract changes, review terms and risks, ensure fulfillment of requirements, maintain contract records, and enter contract data into company systems. Support program management and ensure compliance with company, legal, and customer requirements.

Design, model, test and analyze component- and system-level survivability across RF, IR, visual and acoustic spectrums. Plan and execute RCS/RF tests, develop/validate materials and processes, integrate survivability tech, coordinate with designers and suppliers, produce test reports and recommendations, and support liaison engineering and mission system integration.
