- Be a key contributor towards developing control system architectures for future quantum sensors.
- Collaborate with firmware, software, and hardware design teams to capture requirements.
- Design and deploy electrical test benches for system integration.
- Perform compliance, robustness, and reliability testing on electronic subsystems.
- Support board bring-up and debugging efforts, providing feedback to design teams.
- Develop and maintain an automated test platform using Python.
- Operate and interface with a range of electrical and optical lab test equipment.
- Process and visualize test data, leveraging scripting and analysis tools to extract meaningful insights.
- Work within Git-based software development workflows to track, version, and collaborate on test software.
What We're Looking For
- A Bachelor’s or master’s degree in electrical engineering, Embedded Systems Engineering, Computer Engineering, or a related field.
- 5+ years of relevant industry experience with a focus on hardware validation and system integration testing.
- High proficiency with at least one compiled language (C/C++/Rust).
- Strong programming skills in Python and other scripting languages.
- Hands-on experience with optical and electronic test equipment, including oscilloscopes, DMMs, OSAs, and VNAs.
- Strong understanding of communication protocols (USB, I2C, SPI, serial comms, etc.).
- Ability to process, analyze, and visualize test data to drive design decisions.
- Comfortable working in Linux environments with command-line tools for scripting and automation.
- Experience collaborating with a cross-functional team to support product development from prototype to production.
- Experience with Git and modern software development workflows.
- Strong analytical and problem-solving skills, with experience in root cause analysis and debugging embedded systems.
