**Role & seniority: ** System Test Automation Engineer (mid-level; ~3+ years automation; 2+ years test infrastructure)

**Stack/tools: **

Languages: Python
OS/tech: Linux, shell scripting, system diagnostics
Testing/automation: automation frameworks (UI + backend), QA/system-integration testing
Interfaces/protocols: serial, Ethernet (TCP/UDP), GPIO, USB, APIs; embedded communication
System tools: log analyzers, simulators, reusable test components (data capture/validation)
Top 3 responsibilities:
- Architect and implement system-level HW+SW test automation for integrated multidisciplinary systems (RF, sensors, embedded hardware)
- Build test scripts/frameworks that control/monitor real hardware via serial/Ethernet/GPIO/APIs and exercise edge conditions
- Perform debugging and develop supporting internal tools (e.g., simulators/log analyzers) to validate data and diagnose HW/SW issues
Must-have skills:
- Strong Python + Linux/shell scripting
- Experience building test infrastructure/automation frameworks
- Hands-on with hardware interfaces and diagnostics; ability to write/maintain HIL/embedded-style test flows
- Familiarity with QA/system integration testing process and real-world test planning
Nice-to-haves:
- Experience with hardware-in-the-loop, embedded platforms, or RF/GNSS systems
- Prior work with RF/sensor signal testing and complex multidisciplinary verifi

Full 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 a System Test Automation Engineer to drive system-level (HW+SW) verification for our products. As a System Test Automation Engineer, you’ll architect and implement automation that exercises complex, integrated systems, not just software layers. You’ll design tools and frameworks that interact with real hardware, real sensors, and real signals.

Key Responsibilities Design and build automation frameworks for testing multidisciplinary systems including RF, sensors, and embedded hardware Develop test scripts that connect to real hardware through various interfaces (serial, Ethernet, GPIO, APIs) Perform both manual and automated testing, developing test plans based on real-world use cases and edge conditions Debug hardware and software issues Build internal testing tools (log analyzers, simulators, etc.) and create reusable testing components for data capture, validation, etc.
