What is a HIL Test Engineer?

A HIL (Hardware-in-the-Loop) Test Engineer is responsible for developing, executing, and maintaining test systems that simulate real-world hardware environments for validating embedded systems. They design and implement test automation, work with hardware and software teams, and analyze test results to ensure system reliability. HIL Test Engineers are commonly found in industries such as automotive, aerospace, and industrial automation. Their role is critical in detecting issues early in the development cycle, improving product quality, and reducing time-to-market.

What are some typical challenges faced by HIL Test Engineers, and how do they overcome them?

HIL Test Engineers often encounter challenges such as troubleshooting complex system integration issues, managing evolving test requirements, and maintaining test system reliability. To overcome these obstacles, they work closely with software and hardware developers to quickly diagnose problems, adapt test scripts, and ensure continuous improvement of test setups. They also document findings thoroughly and collaborate with the wider engineering team to implement solutions. This collaborative and dynamic environment helps ensure high-quality product development and rapid iteration cycles. Being adaptable and detail-oriented is key to thriving in this role.

What are the key skills and qualifications needed to thrive as a HIL Test Engineer?

To thrive as a HIL (Hardware-in-the-Loop) Test Engineer, you need a solid background in electrical engineering, embedded systems, and software testing, typically supported by a bachelor's degree in engineering or a related field. Familiarity with MATLAB/Simulink, HIL simulation platforms (such as dSPACE or NI), and scripting languages like Python is crucial, along with relevant certifications in automation or systems testing. Strong problem-solving skills, attention to detail, and the ability to communicate clearly with cross-functional teams are key soft skills for this role. These competencies ensure reliable validation of complex systems and enable effective collaboration with development and engineering teams.

Systems Software Test Engineer

Taara Connect, Inc

Sunnyvale, CA • On-site

Full-time

Re-posted 11 days ago

Job description

About the Team
Born at X, Google's Moonshot Factory, Taara is on a mission to connect billions of people lacking abundant and affordable internet today by pioneering the way we use light to deliver faster, cheaper, more reliable connectivity. Join us to ensure the reliability of our groundbreaking wireless optical communication and photonics chip technologies as we scale across the world.
About the Role
Taara is looking for a Systems Software Test Engineer to lead the automation and validation of our end-to-end systems. This isn't just about testing APIs; you will be responsible for building the frameworks that validate how our software controls high-precision hardware in real-time. You will bridge the gap between software development and hardware reliability, ensuring that every code commit improves our network's stability in the field.
How you will make 10x impact:
  • Architect Automated Frameworks: Design and build scalable automation frameworks from the ground up to test embedded software and cloud integrations.
  • Hardware-in-the-Loop (HIL): Develop and maintain HIL test benches where real-time software meets physical hardware units, simulating complex field conditions.
  • CI/CD Integration: Own the integration of automated tests into the CI/CD pipeline, ensuring high-quality gates for every build.
  • End-to-End Validation: Work with both the Cloud and Embedded teams to validate the entire data path-from the physical optical link to the backend monitoring dashboard.
  • Regression & Performance: Create automated regression suites that catch performance regressions in network throughput, latency, and system stability.

What you should have:
  • Education: Bachelor's degree in Computer Science, Computer Engineering, a related technical field, or equivalent practical experience.
  • Experience: 4+ years of experience in software testing, QA automation, or system validation.
  • Test Automation: Strong proficiency in Python for test script development and automation.
  • CI/CD Mastery: Hands-on experience with GitHub Actions, Jenkins, or GitLab CI, focusing on automated trigger systems and reporting.
  • Hardware-in-the-Loop (HIL): Proven experience testing software on physical devices or using simulation environments (e.g., Raspberry Pis, custom PCBs, or networking gear).
  • Networking Fundamentals: Good understanding of networking protocols (TCP/IP, Ethernet, VLANs) and tools (Wireshark, iPerf).
  • Location: Ability to work in the Sunnyvale office at least 3 days per week.

It would be great if you also had these:
  • Telecom/ISP Background: Experience with network management protocols like gRPC, and SNMP.
  • Physical Layer Testing: Experience with optical sensors, motors, or wireless communication testing.
  • Infrastructure as Code: Experience using Docker/Kubernetes to containerize test environments.
  • Data Analysis: Ability to use SQL or Python (Pandas/NumPy) to analyze large sets of telemetry data from field tests.
  • Creative Breaking: A passion for finding "edge cases" (pun intended) where weather or physical movement might affect software performance.

The US base salary range for this full-time position is $160,000-$210,000 + bonus + equity + benefits. Our salary ranges are determined by role, level, and location. Within the range, individual pay is determined by work location and additional factors, including job-related skills, experience, and relevant education or training. Your recruiter can share more about the specific salary range for your location during the hiring process.
