Simulation Systems Integration Engineer

Standard Job 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.   A Level 5 Simulation Integration Engineer is a senior role responsible for architecting, validating, and deploying complex modeling and simulation frameworks that bridge  physics based simulations with physical hardware. Candidates must typically possess a STEM Bachelor’s Degree with 8+ years of experience, or a Master's degree with 7+ years of experience.   We are seeking an innovative, highly technical Level 5 Simulation Integration Engineer to lead the design, development, and validation of an integrated system level simulation. Including hardware-in-the-loop (HWIL) and software-in-the-loop (SWIL) test environments. In this role, you will join a fast paced system level simulation team, leading  cross-functional integration activities, ensure simulation fidelity, and act as the principal bridge between software, hardware, and systems engineering teams.

Simulation Architecture: Architect, build, and maintain scalable virtual environments, digital twins, and simulation frameworks. Integration & Verification: Lead subsystem’s (PSOC & Reentry), hardware-in-the-loop (HWIL) and software-in-the-loop (SWIL) simulation integration into the system level simulation. Validate simulation models against real-world hardware behavior and testing data. Identify, pursue, and implement 1LMx solutions for simulation, analysis, and MBSE across the FBM program Cross-Functional Leadership: Serve as a technical authority, guiding junior and mid-level engineers in the integration and testing processes. Tool Development: Develop and deploy custom scripts, APIs, and plugins to connect domain models, allowing for seamless data exchange between simulation and SCADA/control systems. Technical Documentation: Author master test plans, system requirements, and interface control documents ensuring alignment with industry and government guidelines. Root Cause Analysis: Identify and troubleshoot system anomalies. Trace discrepancies to either simulation artifacts or hardware integration flaws and implement corrective actions.   The information below reflects the standard job description for this position  Performs technical planning, system integration, verification and validation, cost and risk, and supportability and effectiveness analyses for total systems. Analyses are performed at all levels of total system product to include: concept, design, fabrication, test, installation, operation, maintenance and disposal. Ensures the logical and systematic conversion of customer or product requirements into total systems solutions that acknowledge technical, schedule, and cost constraints. Performs functional analysis, timeline analysis, detail trade studies, requirements allocation and interface definition studies to translate customer requirements into hardware and software specifications.  Basic Qualifications 
 Experience: Minimum of 8+ years of relevant industry experience (or 7+ years with a Master’s degree) in modeling, simulation, and integration. Technical Proficiency: Expert-level
