Quantum software stack Engineer

About Quobly Drawing upon over two decades of pioneering research from CEA and CNRS, Quobly is helping build a quantum-enabled future by developing universal quantum processors that have the potential to solve currently intractable problems in health, energy, mobility, and more. At Quobly, we believe that professionalism , trust , teamwork , and an environment that encourages all employees to exceed their personal best are fundamental to our collective success. We also believe that fun and celebration are an essential part of any workplace. Key Responsibilities: You will contribute to the development of Quobly’s quantum computer software stack from pulse level QPU programming up to quantum algorithms developer SDK by adapting existing stacks to Quobly’s HW controlling primitives (pulse generation and scheduling). You will adapt existing software technologies such as transpilers, compilers,… to Quobly’s hardware specificities. You will adapt major quantum SDK so that Quobly quantum computer can be programmed from those. You will contribute to the deployment of Quobly’s quantum SDK You will contribute to the support of end users of Quobly’s quantum SDK. For all those subjects you will interact with a multidisciplinary team to understand the needs (what), define, adapt or implement (how) and validate We place a high emphasis on fostering creativity, encouraging diverse perspectives, promoting collaborative efforts, and embracing both agile problem-solving and dependable, consistent performance. Being an early-stage team, you will have the unique opportunity to shape our roadmap and contribute significantly to our endeavors. Preferred Qualifications: You have a knack for python and object oriented programming. You have experience with C, C++ or Rust. You understand the processing stages required for transforming a quantum algorithm described as a logical quantum circuit into a scheduling of pulse controlling silicon or supra HW quantum bit operations and readout. On top of this you have experience or expertise in one of the following subjects: Development, or adaptation of components (compiler, transpiler, hardware backend description,…) of one of the major existing quantum SDK (Circ, QisKit, Amazon Bracket, myQlm,…) to add support for a quantum processor. implementation, or adaptation of a quantum programming language (QisKit, Circ, Q, myQLM, tket,…) Classical or quantum compilation flow. You master collaborative software development practices and tools (git, continuous integration, unit testing, bug tracking,…) You are customer oriented (whether they are internal or external), are able to discuss/understand their needs and support them. You have some knowledge of quantum error correction. If you miss some skills, just think of applying anyway. We are convinced that your experience together with willingness and sense of adventure can make the difference.
