Test Engineer, Hardware-in-the-Loop (HIL)

Nimble • South San Francisco, CA

80d • $100,000 - $150,000

About The Position

You will be taking on a critical responsibility for ensuring the reliability and functional safety of our core robotics control software and firmware. This role sits at the intersection of development and manufacturing, focusing on validation across the software development lifecycle. You will bridge the gap between engineering design and production quality, ensuring that ECUs and sub-assemblies are robust before they reach the final assembly line.

Requirements

• BS or MS in Electrical Engineering, Computer Engineering, or Robotics.
• 1-3 years of professional experience in validating embedded systems, control software, or robotics firmware/middleware.
• Expertise in Hardware-in-the-Loop (HIL) simulation and test methodologies.
• Strong programming skills in Python, C/C++, or similar languages.
• Deep understanding of electrical testing, digital and analog I/O, and communication protocols common in robotics.
• Familiarity with test planning principles, requirements traceability, and formal defect management processes.

Nice To Haves

• Experience with ROS/ROS2 and custom control frameworks.

Responsibilities

• Design, develop, and execute comprehensive test plans for robotics control software, real-time operating systems (RTOS), and embedded firmware.
• Develop and maintain the HIL test environment, combining physical hardware with simulated dynamics and environments.
• Oversee the development and calibration of HIL test benches used to perform functional checks and electrical safety tests on sub-assemblies.
• Integrate high-speed data acquisition (DAQ) systems and cloud infrastructure to capture and analyze sensor readings and power metrics.
• Collaborate with software and electrical engineering teams to implement validation procedures for new firmware releases.
