Standard Job Description

The HWIL Software Integration Engineer (E4) provides senior‑level technical leadership for the development, integration, and verification of real‑time, closed‑loop Hardware‑in‑the‑Loop (HWIL) simulations that fuse missile hardware components with high‑performance software models. With 5 + years of relevant experience, the incumbent operates with technical authority, defines integration strategy, and represents Lockheed Martin to senior government and industry partners on technical matters.

Core Responsibilities

• Software Architecture & Strategy
• Define and evolve the software architecture for HWIL test‑beds, establishing standards for real‑time code, low‑latency data paths, and deterministic execution.
• Lead the adoption of best‑in‑class architecture patterns across the program.
• Missile Software & Model Integration
• Direct the integration of missile flight‑software, guidance algorithms, and sensor models into closed‑loop simulation environments (including 6‑DOF dynamics).
• Real‑Time Integration & Timing
• Ensure end‑to‑end latency and timing budgets are met for hardware‑to‑software interfaces through 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 RTOS, FPGA, or HPC platforms.
• Program Leadership
• Serve as the lead HWIL software engineer, coordinating cross‑functional teams (Systems, Electrical, Mechanical, Test, and Integration).
• Mentor junior engineers and provide technical guidance to multidisciplinary groups.
• Integration & Verification
• Direct software‑hardware integration activities, oversee debugging of interface protocols, timing mismatches, and data‑integrity issues.
• Hardware Interaction & Test Equipment
• Apply advanced hands‑on hardware skills (RF testing, cable‑harness verification, target generation) to support software integration and resolve hardware‑related anomalies.
• Oversee use of test equipment such as oscilloscopes, spectrum/network analyzers, RF signal generators, and high‑speed data acquisition systems.
• Customer & Stakeholder Engagement
• Act as the senior technical liaison with government customers for real‑time simulation support, requirement clarification, and issue resolution.

Basic Qualifications

• Experience: 5 + years in software development, real‑time integration, and HWIL environments; proven track record 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).
• Active Secret clearance
• 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.
• Hands‑on experience with lab equipment (oscilloscope, spectrum analyzer, network analyzer).
• Leadership & Communication: Demonstrated ability to lead multidisciplinary teams, influence senior stakeholders, and produce clear technical documentation and presentations.

Desired Skills

• Experience leading HWIL software integration for missile or aerospace programs, including latency budgeting and deterministic timing verification.
• Familiarity with model‑based development environments and automated code generation for real‑time execution.
• Knowledge of industry standards and best practices for HWIL real‑time simulation design and implementation.
• Experience coordinating with government customers for test support, requirement negotiation, and issue resolution.
