Partner with test and software teams to ensure efficient execution of planned verification activities.

Systems & Software Integration

Serve as a technical liaison between Systems Engineering and Software Engineering teams.
Support software integration planning, readiness reviews, and release coordination.
Evaluate impacts of software changes to system behavior, interfaces, and verification scope.
Participate in architecture, design, and interface reviews to ensure requirements alignment.
Support issue resolution involving system functionality, interoperability, and software performance.

Understand hardware/software interfaces, communication protocols, and subsystem interactions.
Support interface definition and validation between embedded devices, processors, sensors, payloads, and external systems.
Assess integration and verification implications of firmware, software, and hardware revisions.

Program Execution & Technical Leadership

Support Program Increment (PI) planning, staffing assessments, and execution readiness activities.
Prioritize verification and requirements activities to meet schedule and milestone commitments.
Mentor junior engineers on requirements quality, traceability, and verification planning.
Drive continuous improvement in systems/software collaboration, process efficiency, and engineering rigor.

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

Bachelor's degree in Systems Engineering, Software Engineering, Computer Engineering, Electrical Engineering, or related technical discipline with 5–8 years of experience in systems engineering, software engineering, embedded systems, or integration environments.
Experience decomposing system requirements into software-level requirements.
