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 h3About the Role /h3 pWe are seeking a Senior .NET Software Engineer (Embedded Device API) to own a lightweight, secure, and resilient device-side Web API that runs on quantum network nodes. This API enables centralized orchestration services to manage devices remotely, including configuration, monitoring, and operational actions, even under constrained, intermittent, or air-gapped conditions. /p h3Responsibilities /h3 ul liImplement and maintain the embedded device Web API as the primary management interface on the node; ensure compatibility with centralized orchestration services and their end-to-end management workflows. /li liIntegrate telemetry and eventing (OpenTelemetry Collector, SignalR, MQTT) with robust backpressure and offline-buffering strategies. /li liSupport multiple management paths (local console, SSH, remote API) with strict authentication/authorization and auditable actions. /li liOptimize embedded constraints: low memory/CPU, secure update, deterministic startup/recovery, and safe rollback. /li liCollaborate with hardware/firmware and crypto teams to expose device capabilities via stable contracts. /li /ul h3Required Skills /h3 ul li8+ years in .NET backend with experience on edge/embedded Linux services or appliance-style products. /li liStrong security (TLS/mTLS, cert pinning, secure storage) and defense-in-depth mindset. /li /ul h3Preferred Skills /h3 ul liExposure to SDN concepts /li liFamiliarity with network management standards (e.g., NETCONF/YANG) /li liKnowledge of quantum networking and device-management interfaces /li /ul h3Equal Opportunity Statement /h3 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
