Job Description

Hermeus is a high-speed aircraft manufacturer focused on the rapid design, build, and test of high-Mach and hypersonic aircraft for the national interest. Working directly with the Department of Defense, Hermeus delivers capabilities that will ensure that our nation, and our allies, maintain an asymmetric advantage over any and all potential adversaries.

We are seeking a multidisciplinary engineer that will help us 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.

We are open to hiring a fresh graduate with experience working on a highly integrated school project/team like Cubesat, Rocketry, Drone Racing or similar.

Key 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.

Required Qualifications:

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.

Preferred Qualifications:

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.

U.S. EXPORT CONTROL COMPLIANCE STATUS

The person hired will have access to information and items subject to U.S. export controls, and therefore, must either be a “U.S. person” as defined by 22 C.F.R. § 120.62 or otherwise eligible for deemed export licensing. US persons include U.S. citizens, U.S. nationals, lawful permanent residents (green card holders), and asylees and refugees with such status granted, not pending.
