HWIL SW Integration Engineer, Staff - Grand Prairie, TX

Core Responsibilities

• 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).
• 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.
• Serve as the lead HWIL software engineer, coordinating cross functional teams (Systems, Electrical, Mechanical, Test, and Integration).
• 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.
• 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.
• Act as the technical liaison with government customers for real time simulation support, requirement clarification, and issue resolution.

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.
