Role
Who you are
- A strong candidate will have hands-on experience with test automation, scripting, hardware validation, and embedded system testing in a Linux-based environment
- Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related field
- 5+ years of relevant industry experience with a focus on hardware validation and system integration testing
- Strong programming skills in Python and other scripting languages
- Familiar with at least one compiled language (C/C++/Rust)
- 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 and improvements
- Comfortable working in Linux environments with command-line tools for scripting and automation
- Collaborate 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
Desirable
- Master’s degree in electrical engineering, Computer Engineering, Physics, or a related field
- 10+ years of experience in hardware test and validation
- Experience with firmware integration, embedded system validation, and debugging
- Experience with environmental reliability testing and compliance validation
- Knowledge of regulatory compliance standards relevant to test and validation processes
- Prior experience working with atomic, optical, or quantum technologies
- Ability to travel to support remote test integration and commissioning as required
- Great verbal and written communication skills to effectively share information with technical and non-technical staff
- Strong engagement and collaboration skills with constant drive for success, ownership and pride in your work
- Sense of urgency and responsibility and a true passion for attention to detail where it matters
- Open communication style and extremely positive attitude which shows through consistent daily habits
- Demonstrated problem solving skills and fast learning rate
- Capability of working with both a high degree of autonomy (taking high level goal as an input to discover and execute an optimal plan, gathering required resources to achieve the goal) and collaboratively (soliciting and incorporating input from colleagues as necessary)
What the job involves
- We are seeking a Senior Test Engineer to support the development and validation of an atomic clock product pilot line
- This individual will join the New Product Introduction Team and work across hardware, software, and R&D teams to develop and execute test plans, set up and interface with test equipment, and automate pilot line test processes
- Depending on business needs, this role may perform a combination of some or all the following duties
- Duties, responsibilities, and activities may change, or new ones may be assigned at any time with or without notice
- Develop, maintain, and execute test strategies and test plans for atomic clock systems and subsystems
- Lead End of Line test plan definition for new products and features, in collaboration with firmware, software, and hardware design teams
- Design and deploy optical and electrical test benches for system integration
- Perform compliance, robustness, and reliability testing on electronic and optical 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
Our take
Quantum physics is a rapidly developing scientific field that promises great innovations within computing, with some working quantum computers already existing. However, such computers are extraordinarily expensive and complex to operate, making it difficult for startups to leverage the technology and apply it to commercial products.
Infleqtion, previously known as ColdQuanta, develops quantum computers, sensors, and networks, integrating them together to form an ecosystem of cloud-hosted quantum infrastructure readied for commercialization. This empowers businesses to leverage quantum computing without them needing their own quantum computer, accelerating adoption of the tech.
While quantum computing has rapidly developed from proof-of-concept to practical applications in the last decade, it has yet to break into common use. By increasing accessibility to the current state of practical quantum technology, Infleqtion should be able to help disrupt industries across the board. Its research arm, which has retained the "ColdQuanta" identity, remains primed to bring new advances to the space, which will, in turn, be more quickly commercialized. Substantial grants awarded in 2024 will help Infleqtion develop its quantum clock product for precision timing.
