Description
Regulus is an agile defense-tech startup tackling the most complex challenges in counter-drone and uncrewed defense. With hundreds of combat-proven systems deployed by the IDF and global partners, we are now engineering the next generation of C-UxS (Counter-Uncrewed Systems). We leverage advanced electronic warfare and kinetic measures to detect and neutralize hostile threats. If you want to push technological boundaries while safeguarding Israel and our allies, join us at this pivotal stage of our growth.
This is a unique opportunity to join a company at a pivotal growth stage and help shape its products, culture, and future.
We’re looking for a System Test Engineer to drive system-level (HW+SW) verification for our products.
Key Responsibilities:
System Verification & Planning
- Create structured test plans and procedures for integrated software–hardware systems.
- Analyze specifications to design test cases that verify system requirements under nominal and stress conditions.
- Identify edge cases in the data flow between hardware peripherals and the software stack.
Lab Integration
- Build and maintain test beds, ensuring interoperability between networking, sensors, receivers, and RF hardware.
- Configure system components (drivers, permissions, services) to replicate complex field environments in the lab.
Deep-Dive Troubleshooting
- Investigate system failures within the SW, the HW, or when the software meets hardware.
- Isolate root causes by analyzing kernel logs, system logs, and driver behavior.
- Distinguish between hardware faults, driver issues, and software logic errors.
Scripting & Tooling
- Develop lightweight scripts (Bash, Python) to automate environment setup, log parsing, and verification steps.
Profile fit:
- You are a Systems, not SW, person at heart.
- You prefer the terminal shell over the GUI.
- You will first dig into logs and hardware configurations to verify that the system works exactly as designed.
Requirements
- Proven experience in verifying complex HW/SW integrated systems (not just web/app testing).
- Coding (python or other) or scripting (Bash, grep, awk) hands on ability.
- Ability to diagnose multi-layer issues.
- Discipline in recording verification results, tracing to requirements, and tracking defects using standard tools.
- Ability to design and document test scenarios based on familiarity with requirements or regular work with the developers.
- Contribute to the continuous improvement of the verification infrastructure.
- Desired - Understanding of the Linux OS (file systems, networking, permissions, systemd services).
- Desired - Experience with RF, GNSS, or Embedded Systems.
- Desired - Experience with standard lab test equipment - oscilloscopes, spectrum analyzers, etc..
