PpID Quantique (IDQ) as part of IONQ, is a global leader in quantum-safe communications and quantum detection systems. We provide solutions to protect governments, telecommunication infrastructures, and banking financial institutions from the “harvest-now, decrypt-later” threat, delivering both terrestrial and space-based quantum-safe networks in live operation globally. Our Quantum Detection Systems push the limits of single-photon detection, powering breakthroughs in quantum communication, sensing, computing, and ultra-sensitive imaging in partnership with top researchers and tech innovators worldwide. /p h3What to expect /h3 pWe are seeking a bModule Architect (.NET) – Control Plane Core /b to design and build modular, secure .NET components for the quantum network Control Plane. This layer orchestrates, manages, and monitors quantum devices handling onboarding, configuration, operational workflows, and providing visibility through stable, extensible APIs. /p h3What you'll be doing /h3 ul liOwn the module architecture for core control plane services (REST APIs, orchestration, configuration), with explicit boundaries to data services, key-management services, and identity/access layers. /li liDevelop and maintain production .NET code in the Control Plane solution: implement core modules, contribute to shared libraries, review pull requests, and troubleshoot issues across environments. /li liDefine plugin entry points and extension points for business domains (for example: quantum key distribution, key management, and network management), with versioned contracts and a clear compatibility strategy. /li liDrive security-by-design (OpenID Connect, role-based access control, mutual TLS, certificate lifecycle, and crypto agility including post-quantum readiness), aligned with centralized identity, authentication, and authorization patterns (for example: Keycloak). /li liEstablish architectural runways: reference implementations, coding standards, API governance (OpenAPI/Swagger), and secure development/quality gates (testing, code review, and security checks in CI/CD). /li liPartner with the centralized orchestration services team (sometimes referred to as the Central Server) and the device team to keep end-to-end workflows consistent; standardize telemetry with OpenTelemetry and ensure reliable device-to-platform messaging (for example: MQTT). /li /ul h3What you'll bring /h3 ul li10+ years in .NET (ASP.NET Core, C#), including architect roles on distributed systems. /li liProven record designing plugin/extensibility frameworks and stable API contracts. /li liStrong security background (OIDC/OAuth2, mTLS, cert lifecycle, RBAC, zero-trust architecture). /li /ul h3You'll be a great fit with /h3 ul liPost-quantum cryptography (PQC) and crypto-agility exposure; regulated/telecom or high-security environments. /li liExperience with policy-based authorization (for example: Open Policy Agent), multi-tenant controls, and observability/telemetry with OpenTelemetry. /li liSDN and network management standards exposure (for example: NETCONF/YANG); familiarity with PKI concepts and operations. /li liFamiliarity with ETSI standards related to quantum key distribution and key-management interfaces is a plus. /li liKnowledge of quantum networking and device-management interfaces is desirable. /li /ul h3What We Offer /h3 ul liA role at one of the fastest growing and most exciting Quantum companies in the world. /li liA competitive compensation scheme, benefits package and equity plan. All designed to reward excellence. /li liFlexible work models that let you balance your life, your family, and your career. /li liOngoing training and development to keep your skills sharp and your growth on track. /li liA career development plan within the IonQ group’s companies. /li liA dynamic, close-knit environment where you collaborate with a global team of experts. /li liA performance-driven culture built on trust, teamwork, and shared ambition. /li /ul pID Quantique/ IonQ is an equal opportunity employer and considers qualified applicants for employment without regard to race, color, creed, religion, national origin, sex, sexual orientation, gender identity, age, disability, veteran status or any other status protected by law. /p /p #J-18808-Ljbffr
