Embedded Integration Systems Engineer Sr

Description: Space is a critical domain, connecting our technologies, our security and our humanity. While others view space as a destination, we see it as a realm of possibilities, where we can do more — we can innovate, invest, inspire and integrate our capabilities to transform the future.

At Lockheed Martin Space, we aim to harness the full potential of space to cultivate innovation, reduce costs, and push the boundaries of what technology can achieve. We’re creating future-ready solutions, focusing on resiliency and urgency through our 21st Century Security® vision. We’re erasing boundaries and forming partnerships across industries and around the world. We’re advancing spacecraft and the workforce to fuel the next generation. And we’re reimagining how space can connect us, ensuring security and prosperity.

Join us in shaping a new era in space and find a career that's built for you.

The Embedded Integration Systems Engineer is responsible for defining, developing, and maintaining the architecture and models of subsystem packages that contain embedded hardware, circuitware, and software elements. This role ensures that each package meets its functional, performance, and interface requirements while providing clear insight into how the embedded components operate within the larger system. The engineer partners with cross‑functional teams to manage package‑level configuration, interface development, and performance metrics.

Key Responsibilities:

Package Architecture Management
-Develop and maintain package‑level architecture models (functional, logical, and physical) for embedded hardware‑software integrations.
-Produce and update functional/logical block diagrams, state‑mode charts, functional flows, sequence‑of‑event timelines, mission‑critical events, and Concept of Operations (ConOps) for each package.
-Collaborate with systems, hardware, firmware, software, test, and program teams to gather, refine, and validate package functions.
-Perform analyses to verify that package functional requirements align with package specifications and overall system objectives.

Configuration (Cameo) Management
-Own configuration management of package architecture models using Cameo Systems Modeler (or equivalent MBSE tool).
-Ensure all architecture changes are documented, reviewed, and approved in accordance with configuration‑control processes.
-Coordinate with the design and embedded‑software teams to keep architecture baselines synchronized with detailed design deliverables.

Package Interface Management
-Lead development of functional and physical interface requirements at the package level, emphasizing embedded interfaces (e.g., data buses, memory maps, timing signals).
-Support creation and maintenance of Interface Correlation Documents (IcDs) for the package and maintain traceability between interface requirements, architecture models, and downstream design artifacts.
-Work with system‑level interface managers to resolve conflicts and ensure package interfaces remain coherent with the overall system architecture.

Package KPI Management
-Define, develop, and maintain package‑specific Key Performance Indicators (KPIs) that capture embedded performance metrics such as processing latency, power consumption, reliability, and mission‑critical timing.
-Track KPI trends, generate status reports, and provide actionable insights to the system‑level KPI manager.
-Ensure accurate roll‑up of package performance data to support system‑level performance assessments and decision‑making.
