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.
