Role & seniority: System Test Engineer (mid-level, hardware–software verification focus)

Stack/tools: HW/SW integrated systems; Linux (file systems, networking, systemd); Python or other coding; Bash/grep/awk scripting; kernel and system logs; lab test equipment (oscilloscopes, spectrum analyzers); defect tracking and requirements tracing

Top 3 responsibilities

System Verification & Planning: create test plans/procedures for integrated software–hardware systems; design test cases from specs; cover nominal and stress conditions
Lab Integration: build/maintain test beds; ensure interoperability of networking, sensors, receivers, RF hardware; configure components to mirror complex field environments
Deep-Dive Troubleshooting: investigate failures across SW/HW; isolate root causes via logs and driver behavior; distinguish hardware, driver, and software issues; develop automated verification steps

Must-have skills

Proven experience verifying complex HW/SW integrated systems (beyond web/app testing)
Practical coding/scripting ability (Python or equivalent; Bash, grep, awk)
Ability to diagnose multi-layer issues and trace verification results to requirements
Disciplined test documentation, result recording, defect tracking, and test scenario design
Contribution to verification infrastructure improvements

Nice-to-haves

Linux OS proficiency (filesystems, networking, permissions, systemd)
Experience with RF, GNSS, or embedded systems

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 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..
