You will build the layer through which the world reaches our quantum computers. Users submit quantum programs; your services compile, schedule, and dispatch them to our machines and return the results: * Build and operate the cloud services that let users submit quantum programs to our systems and retrieve their results. * Develop and deploy our compilation pipeline as a scalable cloud service , from circuit input through transpilation down to hardware-level instructions * Design and maintain the public API and SDK entry points to our platform * Implement job queuing, scheduling, and dispatch towards the hardware backends, including quota, prioritisation, and result handling * Own authentication and authorisation across the platform: user and tenant identity, API keys and tokens, and role-based access to machines, jobs, and results, built on an established identity provider rather than from scratch * Guarantee tenant isolation, so that quantum programs and results are never visible across customer boundaries, and manage secrets and credentials across the stack * Work with the quantum firmware and hardware teams on the interfaces between cloud services and the machine itself * Instrument the platform for observability and keep an eye on latency, throughput, and cost, * Flexible working hours: We offer personal freedom through a variety of flexible work schedules * Team spirit: In our international and diverse team, and with our regular team events, having fun at work is simply part of the culture * Further development: We want to grow together and so we offer our team members needs-based, individualized further training as well as plenty of room for personal development * Wellness Package: We offer health-promoting benefits such as fitness programs like UrbanSportsClub to support your well-being * Bike Leasing: Stay Mobile and Sustainable with Our Company Bike Leasing Program * Moving Benefits: A warm welcome! We are happy to support employees who move for us with a bonus * At the forefront: Work at the forefront of technology, where academic research meets commercial applications * Modern workplace: We have a high-quality infrastructure with laboratory space, offices and meeting rooms
