Hil Testing information
What is a HIL Testing job?
A HIL (Hardware-in-the-Loop) Testing job involves validating and verifying embedded systems by simulating real-world scenarios using hardware and software models. Engineers in this role develop test cases, automate testing procedures, and analyze system behavior to ensure reliability and performance. HIL testing is commonly used in industries like automotive, aerospace, and industrial automation to test control systems before deployment.
What does a typical day look like for someone working in HIL Testing?
A typical day in HIL Testing involves designing and setting up test benches, running simulations of real-world scenarios on hardware prototypes, analyzing results, and documenting any issues or anomalies found. You'll work closely with hardware designers, embedded software engineers, and project managers to develop test cases and troubleshoot control systems. The role often requires managing multiple test cycles, adapting to evolving specifications, and participating in team meetings to review progress. This hands-on environment combines a mix of technical work, problem-solving, and collaborative communication to ensure the proper functioning and safety of complex electronic systems before they are deployed in the field.
What are the key skills and qualifications needed to thrive in the Hil Testing position, and why are they important?
To thrive in HIL (Hardware-in-the-Loop) Testing, a strong background in electrical engineering, embedded systems, and test automation is essential, often supported by a relevant engineering degree. Experience with tools such as dSPACE, NI LabVIEW, MATLAB/Simulink, and knowledge of real-time simulation platforms are highly valued, and certifications in software or hardware testing can be advantageous. Critical thinking, problem-solving, and effective communication are important soft skills for diagnosing issues and collaborating closely with multidisciplinary engineering teams. These competencies ensure accurate validation of complex control systems and help deliver reliable, high-quality products in industries like automotive and aerospace.

Job description
Zetier seeks Software Development Engineers in Test (SDET) to design, build, and maintain scalable automated testing capabilities for embedded hardware, cyber platforms, and operational software systems. This role focuses on developing robust test infrastructure, improving product reliability, and enabling continuous validation across hardware and software solutions. Candidates will develop automated validation frameworks, integrate testing into CI/CD pipelines, and support verification activities spanning low-level firmware, networking systems, and mission-driven software capabilities. Work includes functional, integration, regression, and hardware-in-the-loop testing aligned with quality, operational effectiveness, and compliance objectives.
Required:
- 5+ years experience in software development or test engineering
- Strong programming experience in Python, C/C++, and/or Rust
- Experience deploying automated test frameworks (e.g. pytest, Robot)
- Experience testing embedded or Linux-based systems platforms
- Hands-on experience integrating testing into CI/CD pipelines
- Familiar debugging complex HW/SW system interactions
- Comfortable writing clear technical documentation (e.g. test reports)
- Strong communication skills across engineering and customer teams
- Active U.S. security clearance
Desired:
- Experience with hardware-in-the-loop (HIL) and device automation
- Experience testing embedded systems, networking devices, or mobile
- Experience with containerization (e.g. Docker, Kubernetes, QEMU)
- Familiar with network/protocol validation (e.g. Wireshark, Scapy)
- Experience with RF or wireless systems (e.g. 802.11ac, Zigbee, SDR)
- Experience testing firmware, drivers, and low-level code/services
- Exposure to cybersecurity, vulnerability research, or pentest teams
- Experience with observability, telemetry, or reliability engineering
