This role serves as a critical bridge between Systems Engineering and Software Engineering, ensuring requirements are properly decomposed, traceable, testable, and aligned to overall program objectives. The position is organizationally aligned within the Systems Engineering function while working closely day-to-day with the Software Engineering team to support planning, development, integration, and verification activities. This role is instrumental in defining software verification approaches, required hardware/software configurations, and ensuring system functionality meets mission and performance objectives. ESSENTIAL ROLES AND RESPONSIBILITIES Requirements Decomposition & Flow Down * 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 * Develop software verification approach including verification descriptions, methods (test, analysis, demonstration, inspection), levels, and acceptance criteria aligned to system and program requirements. * Identify required verification configurations, including hardware setups, software loads, firmware versions, and test environments. * Support verification cross-reference matrices (VCRM), traceability matrices, and evidence packages. * 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., Senior digital product manager for retail lending who defines digital strategy, designs and prioritizes digital experiences, builds business cases, manages development and launches, partners with stakeholders (Technology, Marketing, MIS, LOB), coaches product teams, and supports risk, compliance, and audit needs.
