HWIL SW Integration Engineer Sr (E3) | Orlando, FL | 10669 with Security Clearance

Job Number 10669 Standard Job Description The HWIL Software Integration Engineer (E3) provides technical support for the development, integration, and verification of real-time, closed-loop Hardware-in-the-Loop (HWIL) simulations that combine missile hardware components with high-performance software models. With 3+ years of relevant experience, the incumbent works under senior guidance, contributes to integration strategies, and represents Lockheed Martin to government and industry partners on technical matters. Core Responsibilities

• Software Architecture & Strategy
• Assist in defining and maintaining the software architecture for HWIL test-beds.
• Support standards for real-time code, low-latency data paths, and deterministic execution.
• Missile Software & Model Integration
• Contribute to the integration of missile flight software, guidance algorithms, and sensor models into closed-loop simulation environments (including 6-DOF dynamics).
• Real-Time Integration & Timing
• Help ensure latency and timing budgets are met for hardware-to-software interfaces by performing time-domain analysis and jitter budgeting.
• Implement and verify synchronization mechanisms between missile hardware (actuators, sensors, RF targets) and simulation models on RTOS or FPGA/HPC platforms.
• Integration & Verification
• Participate in software-hardware integration activities, debugging interface protocols, timing mismatches, and data-integrity issues.
• Contribute to verification and validation (V&V) plans, traceability matrices, and validation reports.
• Hardware Interaction & Test Equipment
• Apply hands-on hardware skills (RF testing, cable harness checks, target generation) to support software integration.
• Operate test equipment such as oscilloscopes, spectrum/network analyzers, RF signal generators, and high-speed data acquisition systems.

Basic Qualifications

• Experience: 3+ years in software development, real-time integration, and HWIL environments; demonstrated ability to integrate 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).
• 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: Ability to work effectively within multidisciplinary teams, communicate technical concepts clearly, and produce quality documentation.

Desired Skills

• Experience supporting HWIL software integration for missile or aerospace programs, including latency budgeting and timing verification.
• Familiarity with model-based development environments and code generation for real-time execution.
• Knowledge of industry standards and best practices for HWIL real-time simulation design.
• Experience interacting with government customers for test support and issue resolution.
