In this role, you will be responsible for the “quantum cloud infrastructure” that receives execution requests (jobs) from users and efficiently routes and manages their execution on actual photonic quantum computers and simulators. Specific responsibilities include:

・Designing, building, and operating a hybrid cloud/on-premises infrastructure that integrates with actual photonic quantum computers and high-precision simulators

・Developing and designing security for user authentication and authorization systems (OAuth 2.0/OIDC), multi-tenant management, and API gateways

・Developing asynchronous processing infrastructure to efficiently queue and schedule quantum computing jobs of various sizes and allocate them to actual hardware resources

・Building dashboards (GUI) for internal and external use, as well as systems for monitoring usage and collecting metrics

Requirements

・Experience (3+ years) in designing, building, and operating Web API and microservices infrastructure on cloud platforms (AWS, GCP, or Azure)
