We are looking for a Principal Software Engineer to help build the software systems, Artificial Intelligence (AI) agents, and automation platforms that power and maintain Azure’s global optical backbone, the foundation of Microsoft’s cloud and AI infrastructure. This role is for engineers who think across layers, from the software running on optical devices that collect and instrument billions of data points, to the distributed high-availability systems that autonomously operate and repair the network. You will design and implement services that act as the sensory, cognitive, and motor systems of our AI-driven operations, safely and securely running one of the most advanced photonic networks in the world. Our team has pioneered several industry-first AI agents and autonomous platforms that define the future of hyperscale network operations. We are looking for someone who thrives at the intersection of systems engineering, large-scale automation, and AI-native infrastructure, helping us evolve from reactive management to a self-sustaining intelligent network. Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond. Required Qualifications: <ul><li>Bachelors Degree in Computer Science or related technical field AND 6+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python<ul><li>OR equivalent experience.</li></ul></li><li>Software &amp; Systems experience: 6+ years building production software for network automation and operations; 4+ years designing and running distributed, highly available services at scale; fundamentals in concurrency, reliability, and performance.</li><li>Programming &amp; Automation experience : 1+ years building closed-loop automation including telemetry collection, streaming/state evaluation, policy orchestration, and safe actuation on network or optical devices and 1+ years of experience with Go or Python.</li><li>Integration &amp; Observability experience: 1+ years with device/controller interfaces including: Network Configuration Protocol/Yet Another Next Generation (NETCONF/YANG), Google Network Management Interface/Google Network Operations Interface (gNMI/gNOI), Simple Network Management Protocol (SNMP), vendor Software Development Kits (SDKs), Remote Procedure Call/Google Remote Procedure Call (RPC/gRPC); observability practices across metrics, logs, and traces, including Service Level Objective (SLO) design, error budgets, and on-call ownership.</li><li>Security &amp; Leadership experience: 3+ years with Secure-by-design mindset (auth, authorization, key/secret management, auditability) and proven ability to lead cross-functional engineering efforts from design to production with measurable outcomes.</li></ul><div> </div>Other Qualifications:<ul><li>Ability to meet Microsoft, customer and/or government security screening requirements are required for this role.
