## About the Role

* Experience: 5 + years in software development, real time integration, and HWIL environments; proven experience integrating missile hardware with real time simulations
 * Education/Training: Bachelor's degree in Computer Engineering, Software Engineering, Computer Science, or related STEM field (Master's preferred)
 * Clearance: Active Secret clearance (interim required at start)
 * Technical Expertise: Proficiency in C/C++ and real time operating systems (e.g., RedHawk, VxWorks, RTLinux); strong understanding of low latency communication protocols (e.g., Ethernet/IP, MIL STD 1553, CAN)
 * Working knowledge of RF testing, target generation equipment, and missile hardware interfaces
 * Strong hands-on skills with lab equipment (oscilloscope, spectrum analyzer, network analyzer).
 * Leadership & Communication: Proven ability to lead multidisciplinary teams, influence senior stakeholders, and produce clear technical documentation and presentations

Desired Skills

 * Demonstrated success leading HWIL software integration for missile or aerospace programs, including latency budgeting and deterministic timing verification
 * Experience with model based development environments and code generation for real time execution
 * Experience with flight software integration, real time operating systems, and high performance computing applied to HWIL
 * Knowledge of industry standards and Lockheed Martin best practices for HWIL real-time simulation design and implementation
 * Experience coordinating with government customers for test support

## Description

* Software Architecture & Strategy - Define and evolve the software architecture for HWIL test beds, establishing standards for real time code, low latency data pathways, and deterministic execution.
 * Lead the development and integration of missile flight software, guidance algorithms, and sensor models into closed loop simulation environments (including 6 DOF missile dynamics).
 * Real Time Integration & Timing - Ensure end to end latency and timing budgets are met for hardware to software interfaces, employing techniques such as time domain analysis, jitter budgeting, and priority based scheduling.
 * Implement and validate synchronization mechanisms between missile hardware (actuators, sensors, RF targets) and simulation models running on real time operating systems (RTOS) and FPGA/HPC platforms.
 * Program Leadership - Serve as the lead HWIL software engineer, coordinating cross functional teams (Systems, Electrical, Mechanical, Test, and Integration).
 * Integration & Verification - Direct software hardware integration activities, overseeing debugging of interface protocols, timing mismatches, and data integrity issues.
 * Author and approve comprehensive verification and validation (V&V) plans; ensure traceability to requirements and produce formal validation reports.
 * Hardware Interaction & Test Equipment - Apply hands on hardware skills (RF testing, cable harness verification, target generation) to support software integration and troubleshoot hardware related anomalies.
 * Operate test equipment such as oscilloscopes, spectrum/network analyzers, RF signal generators, and high speed data acquisition systems.
 * Review and approve engineering deliverables (code, interface specifications, test procedures) to ensure adherence to best practices and Lockheed Martin standards.
 * Customer & Stakeholder Engagement - Act as the technical liaison with government customers for real time simulation support, requirement clarification, and issue resolution.
 * Proficient in AI prompting as it applies to this position and practice.
