Software Engineer HILs

Summary

Hermeus is a venture capital-backed aerospace and defense technology company focused on building high-speed products for the Department of Defense. They are seeking a multidisciplinary engineer to develop Hardware-in-the-Loop (HIL) testbeds for hypersonic aircraft, ensuring product reliability and compliance with specifications.

Responsibilities

• Design, implement, and maintain HIL test benches including low voltage harnesses
• Develop test scripts, models, and automation frameworks to execute and validate embedded control software
• Integrate HIL systems with other avionics components
• Simulate sensor and actuator interfaces using real-time models and signal conditioning hardware
• SIL (Software-in-the-Loop), and HIL test workflows throughout the development lifecycle
• Troubleshoot hardware and software issues on the HIL bench and work cross-functionally to resolve defects
• Create and maintain test documentation including test plans, test cases, and validation reports
• Collaborate with system architects and software engineers to define test coverage and improve test strategies

Skills

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Mechatronics, or a related field
• 2+ years of experience in embedded system or test engineering with HIL systems
• Strong knowledge of MATLAB/Simulink and scripting languages (Python, Julia, etc.)
• Experience in developing and executing test cases for embedded control systems
• Familiarity with communication protocols (CAN, Ethernet, RS-485)
• Strong problem-solving and analytical skills
• Hands-on experience with one of the HIL platforms is a plus (e.g. dSPACE, NI PXI/VeriStand, or Speedgoat with Simulink Real-Time)
• Experience in automotive, aerospace, or industrial automation industries
• Exposure to Agile development processes and CI/CD pipelines (e.g., Jenkins)
• Knowledge of safety-critical systems and relevant standards (e.g., DO-178C, ISO 26262, IEC 61508)
• Experience with automated testing frameworks or tools (e.g., ECU-TEST, TestStand)
• Experience with requirements-based testing and tools like DOORS, Polarion, or Jama
