ResponsibilitiesThis role, as part of the Azure Quantum Hardware & Systems team, will develop software and Register Transfer Level (RTL) across multiple layers of the quantum computing stack, including low level software for 1st and 3rd party lab instrumentation, low level control and readout firmware/software that directly operates the quantum machine, automation used in the bring-up and tuning of the quantum machine, custom quantum machine monitoring solutions, various tooling, and integration with Azure Quantum services. The ideal candidate for this position is agile and able to adapt to changing conditions and priorities as we learn and grow. Such a candidate has excellent communication and cross-team collaboration skills. Develop real-time firmware, drivers, and high-performance user-mode software to operate custom components that comprise the quantum machine. Develop software and hardware to coordinate the control and readout capabilities of our 1st party topological qubit technology. Support hardware design and development of custom components of the quantum machine. Develop custom tooling including Command-Line Interface (CLI) and User Experience (UX) interfaces to support the development and operation of the quantum machine. Implement best practices for software development, build, test, and release processes. Track, prioritize, and implement new features and maintain related software. Troubleshoot, diagnose, and correct issues with the quantum machine hardware or software stack, including software maintenance for custom hardware or software components. Create automated testing processes for the software implementations. Collaborate effectively with a multidisciplinary team of scientists, physicists, hardware engineers, software engineers, and program management to effect successful outcomes. Provide technical support to other internal teams and users of the quantum machine. Support a one team, one culture approach. Other:Embody our Culture and Values
