Monitor system performance, analyze operational data, investigate anomalies, implement software and scripting improvements, support system reconfigurations, and maintain technical documentation and operating procedures. The role requires collaboration with engineers and operators, technical briefings, on-call support, and occasional 12-hour shifts, weekends, and operational travel.

Supports the performance, reliability, and operational readiness of mission systems. Responsibilities include system monitoring, performance analysis, anomaly investigation, recovery support, operational documentation, monitoring-tool development, technical leadership, mentoring, and continuous improvement. The role requires collaboration with engineers, operators, customers, and technical specialists in a defense environment.

Develops and integrates complex systems by analyzing customer requirements, allocating requirements, conducting trade studies, and managing verification and validation. The role supports Agile engineering teams, test planning and execution, troubleshooting, data analysis, simulation model development, and technical baseline management. Responsibilities include ensuring mechanical, electrical, environmental, reliability, and performance requirements are satisfied within schedule and cost constraints.

Leads complex EMI/EMC test campaigns for electronic systems and subsystems, including test planning, equipment setup, execution, data analysis, troubleshooting, root-cause analysis, and compliance reporting. Develops and approves procedures, coordinates readiness reviews and facilities, recommends mitigation strategies, and mentors engineers and technicians. Collaborates with design and systems teams and supports occasional travel, extended work weeks, and weekend testing.

Supports cybersecurity execution across system development and sustainment lifecycles. Responsibilities include identifying and remediating cybersecurity risks, managing vulnerabilities, conducting security scans and assessments, maintaining compliance evidence, verifying requirements, and coordinating with engineering, software, testing, configuration management, and program teams. The role is fully onsite in Rancho Bernardo, California, requires an active Top Secret clearance, and may require travel up to 25%.

Conducts verification and qualification testing for airborne navigation systems across the program lifecycle. Responsibilities include requirements analysis, test plan and procedure development, test execution, readiness reviews, test equipment integration, data analysis, troubleshooting, root cause analysis, formal reporting, and leading cross-functional teams in laboratory and field environments. The role is fully onsite, requires an active Secret clearance and U.S. citizenship, and includes approximately 10% travel.

Architects, develops, tests, debugs, and integrates real-time embedded software for multicore platforms supporting secure missile weapon systems. Translates system requirements into software solutions, defines system architecture, verifies performance, collaborates with hardware and algorithm teams, conducts code reviews, maintains technical artifacts, and mentors junior engineers. The role is full-time onsite in Northridge, California and requires an active Secret clearance.

Develops and integrates complex systems by translating customer requirements into design documentation, allocating and verifying requirements, performing functional and trade studies, and designing validation tests. Conducts hands-on electrical and system-level testing, investigates hardware discrepancies, identifies root causes, and drives corrective actions. Leads technical problem-solving, supports test activities, manages requirements baselines, and collaborates with multidisciplinary teams and external customers in an onsite defense engineering environment.

Leads cybersecurity execution for aerospace systems, including security architecture, RMF and JSIG compliance, accreditation packages, vulnerability assessments, system hardening, requirements traceability, and risk remediation. The role coordinates across engineering, software, testing, security, customers, and program teams; presents technical materials; mentors stakeholders; and supports secure system development and sustainment. Full-time onsite work is required in Rancho Bernardo, California, with travel up to 25%.

Leads mechanical integration and testing of space flight hardware from subassembly through complete systems. Responsibilities include work-package procurement, manufacturing, integration, test, delivery, cost and schedule ownership, test procedure development, anomaly resolution, non-conformance remediation, and cross-functional coordination. The role requires leadership in complex aerospace production environments, technical planning, resource allocation, and execution of mission-critical programs.
