• Collaborate closely with physicists and hardware engineers to understand lab workflows and deliver tailored software tools.
• Develop and maintain internal tools and dashboards to visualize equipment status, monitor system health, log experimental runs, and track lab activity in real time.
• Enhance system observability to support rapid debugging of issues and minimize operational downtime, including clear and actionable error reporting for end users.
• Write clear, maintainable, and testable code in a fast-paced R&D environment.
• Deploy and support lab software throughout its lifecycle, including updates, maintenance, and troubleshooting.
• Diagnose and resolve various software issues across the software stack, bringing in appropriate support from the broader software team as needed.
• Contribute to improving CI/CD workflows, supporting automated testing and build processes.
• Help define and evolve software development best practices, including version control standards, code review processes, and issue tracking conventions.
• Occasional travel up to 10% may be expected.

• Bachelor's degree minimum
• Minimum 4+ years of graduate and/or industry experience developing software in a laboratory or research environment.
• Minimum 2+ years of experience with Python, C++, or similar object-oriented programming language.
• Minimum 1+ years of experience developing software that communicates with physical hardware via device interfaces, control protocols, and/or instrumentation libraries.
• Due to Contractual requirements, must be a U.S. Person defined as, U.S. citizen permanent resident or green card holder, workers granted asylum or refugee status.
• Due to national security requirements imposed by the U.S. Government, candidates for this position must not be a People's Republic of China national or Russian national unless the candidate is also a U.S. citizen.

• Masters/PhD degree in Computer Science or field related to Quantum Computing preferred
• Familiarity with experiment automation frameworks or lab control systems.
• Experience with hardware-in-the-loop testing and/or real-time systems.
• Proficiency with Docker and experience managing containerized environments.
• Comfort working in Linux and Windows development environments.
• Knowledge of instrumentation APIs, messaging systems, or device protocols (e.g., serial, GPIB, TCP/IP).
• Experience working with or automating laboratory equipment such as oscilloscopes, waveform generators, motorized stages, and data acquisition systems.

Compensation & Benefits:

The pay range for this role is $132,000 – $152,000 annually. Actual compensation within this range may vary based on the candidate’s skills, educational background, professional experience, and unique qualifications for the role.
