We currently have an exciting opportunity for a Senior Systems Engineer to join our team located in San Diego, CA.

DUTIES AND RESPONSIBILITIES:

Systems Engineering & Architecture Leadership

• Lead software and firmware systems engineering activities for complex, real‑time embedded and mission‑critical systems.

• Serve as the software/firmware system architect, defining end‑to‑end architectures and allocating functionality between hardware, firmware, and software.

• Develop and manage systems engineering artifacts related to software and firmware, including requirements, use cases, interface control documents, data/interface definitions, architecture descriptions, technical baselines, and verification and validation plans.

• Use MBSE and SysML/UML tools to:

• Capture and decompose system, subsystem, and lower‑level software/firmware requirements.

• Develop and maintain system models

• Support design trades and system behavior/performance characterization

• Provide technical guidance to systems engineering staff and integrated product teams; mentor and support the development of junior systems engineers.

• Serve as a key technical contributor and present technical content at internal and customer reviews.

Software/Firmware Development Team Interactions

• Lead the definition and creation of documentation of the software/firmware architecture needed for the program.
• Understand and analyze system‑level requirements and operational use cases.
• Identify required software/firmware functions and performance characteristics.
• Define interfaces between software, firmware, hardware, and external systems.
• Work closely with software and firmware development teams to support their design, implementation, and testing of the software/firmware in accordance with the defined architecture.
• Ensure developers have clear requirements and interface definitions to facilitate feedback on feasibility, complexity, and implementation risks.
• Incorporate developer feedback and lessons learned from design and integration into updates of the architecture and requirements.
• Maintain architectural coherence, traceability, and alignment with system requirements and developer led design.

Integration and Test Support

• Support the development of integration and test plans and procedures for software/firmware and system‑level verification and validation.
• Focus on requirements verification and validation against the defined architecture, interface verification, and end‑to‑end functional behavior.
• Feed lessons learned from lab and field testing back into the architecture, requirements, and test plans.
• Participate in test readiness reviews, anomaly documentation, root‑cause analysis, and resolution.
• Ensure that architecture, requirements, and test artifacts remain consistent in a digital engineering environment.

Cross‑Functional Collaboration

• Collaborate with program management, software/firmware developers, and other functional teams on design, integration, and test activities.
• Participate in and present at program design and readiness reviews throughout the lifecycle.
• Interface with customers to understand needs and communicate technical status.
• Generate technical documentation and presentations that will be used by other engineering disciplines to support programs, proposals, and internal development opportunities.
• Maintain strict confidentiality of sensitive information and comply with all applicable laws, regulations, and company policies; work safely in accordance with established procedures

We recognize and appreciate the value and contributions of individuals with diverse backgrounds and experiences and welcome all qualified individuals to apply.
