Analyze customer, mission, and system-level requirements and decompose them into clear, verifiable software-level requirements.
Ensure software requirements maintain traceability to higher-level system requirements, architecture, and Concept of Operations (CONOPS).
Collaborate with systems, software, and hardware teams to refine requirements for completeness, feasibility, and technical accuracy.
Support requirements management processes, baseline control, and change impact assessments.
Identify requirement gaps, ambiguities, and risks early in the development lifecycle.

Verification Planning & Validation

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.

Embedded Systems & Interfaces

Apply working knowledge of embedded systems architectures, constraints, and development environments.
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.
Experience creating verification plans, descriptions, procedures, or acceptance criteria.
Strong understanding of embedded systems and software development lifecycles.
Experience with hardware/software interfaces and communication protocols.
Ability to interpret and apply system-level CONOPS to engineering execution.
