Cloud Engineer - Quantum Computing (m/w/d)

Meyandy LLC; Nordrhein-Westfalen; Hybrid; EUR 70.000 - 90.000; Vollzeit

Zusammenfassung

eleQtron in Hamburg or Siegen seeks a Cloud Engineer (m/f/d) to build and operate the scalable cloud platform that connects users to trapped-ion quantum computers. You will deploy a robust backend, design APIs, and ensure secure, multi-tenant access to quantum resources.

Responsibilities include building the submission, compilation, and dispatch pipeline, as well as authentication, authorization, observability, and cost monitoring. English fluency is required; German is a plus.

Qualifikationen

• You have 3+ years of hands-on experience building and deploying backend or platform services in production.
• You are proficient in Python with a systems-level mindset and strong API design skills.
• You implement authentication and authorization using OAuth 2.0 / OpenID Connect and RBAC.

Aufgaben

• You will build and operate the cloud services that let users submit quantum programs and retrieve results.
• You will design and maintain the public API and SDK entry points to the platform.
• You will implement job queuing, scheduling, and dispatch to hardware backends with quota and prioritisation.
• You will own identity, secrets management, and tenant isolation across the stack.

Jobbeschreibung

## Description du poste**eleQtron** develops and operates full-stack quantum computers based on trapped-ion technology. Quantum computing is a new computing paradigm rapidly approaching commercial viability. Our unique approach combines laser-cooled trapped ions with microwave control and tailored magnetic fields. Our next-generation computing machines under development will be able to find solutions to problems that are out of reach today, thus enabling new innovative products and services for a brighter future.**We are looking for a Cloud Engineer (m/f/d) to join us in Hamburg or Siegen and build and operate the scalable, secure cloud platform that connects users with our trapped-ion quantum computers.****Responsibilities:**You will join our Quantum firmware Team as a Cloud Engineer. 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 **Required Skills:*** 3+ years of hands-on experience building and deploying backend or platform services in production* Strong Python; additional systems-level language experience (Go, Rust, C++) is welcome* Solid API design skills (REST and/or gRPC) for services other developers have to use* Practical experience implementing authentication and authorisation in production systems: OAuth 2.0 / OpenID Connect, token handling, and role-based access control* Secure engineering habits: least privilege by default, proper secrets management, and awareness of dependency and container supply-chain risks* Infrastructure as code (Terraform, Pulumi, or similar) and CI/CD pipelines (GitLab CI, GitHub Actions, or similar)* Working understanding of GDPR and data residency requirements, and a genuine interest in digital sovereignty* Ability to collaborate effectively with experimental physicists and engineers* Strong adaptability and a quick learning mindset* Good proficiency in English (written and spoken); German is an advantage for working with public-sector partners**Nice to have (Bonus)*** Running an identity provider in production (Keycloak, Zitadel, Ory, Authentik, or a managed IAM service)* Multi-tenant isolation patterns in SaaS platforms* Contributing to security certification work (ISO 27001, BSI IT-Grundschutz, BSI C5) or acting on penetration test findings* Familiarity with quantum SDKs and toolchains (Qiskit, Cirq, PennyLane, QIR) or hardware abstraction interfaces such as QDMI* Batch scheduling or HPC environments (Slurm or similar)* Observability stacks such as Prometheus, Grafana, or OpenTelemetry* Prior exposure to quantum computing or other deep-tech domains**What you can expect from eleQtron:*** **Competitiv...**
