About The Position

Hermeus is a venture capital-backed aerospace and defense technology company focused on building high-speed products that sustainably deliver asymmetric advantage to the Department of Defense and allied partners. We are seeking a multidisciplinary engineer to help develop our next generation Hardware-in-the-Loop (HIL) testbeds for our hypersonic aircraft. In this role, you will be responsible for designing, developing, and maintaining HIL testbeds that will validate complex avionics systems. You will work closely with software, hardware, and systems engineers to ensure product reliability, functionality, and compliance with specifications.

Requirements

• 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.

Nice To Haves

• 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.

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.
