Overview
At Microsoft, we're a community of passionate innovators driven by curiosity and purpose. We collaborate to imagine what's possible and accelerate our careers in a cloud-powered world where openness and innovation unlock limitless potential.
Artificial Intelligence is central to Microsoft's strategy-and the Azure AI Platform is leading the charge. As part of our team, you'll contribute to cutting-edge projects that solve real-world challenges using transformative technologies.
We are looking for a Senior Software Engineer to join our fast-paced, agile team at the core of Microsoft's AI infrastructure. This team builds and operates the Next Generation Traffic Shaping, Scheduling, and Optimization Platform-a foundational control-plane service responsible for intelligent routing, capacity allocation, quota enforcement, and workload optimization for OpenAI models and other large-scale AI workloads across Azure.
In this role, you will help define and build the systems that determine how AI traffic is routed and served globally. You will work on the Traffic Shaper, the critical platform that dynamically balances demand across thousands of AI endpoints, optimizes utilization of premium AI accelerators, and ensures reliable, low-latency experiences for Microsoft Copilot, Azure OpenAI Service, and strategic enterprise customers.
You will design and develop large-scale distributed systems responsible for:

• Intelligent request routing and workload placement across global regions.

• Capacity management and allocation across models, tenants, and customer offerings.

• Real-time traffic shaping, prioritization, and load balancing.

• Quota management, throttling, and fairness enforcement.

• Fleet-wide optimization to maximize GPU utilization and service efficiency.

• High-fidelity telemetry, observability, and automated operational controls.

• Resiliency, failover, and incident mitigation mechanisms for mission-critical AI services.

As a senior engineer, you will provide technical leadership across projects, drive architecture decisions, influence platform strategy, and partner closely with teams across Azure AI, OpenAI, Infrastructure, Networking, and Core AI Services. You will own services operating at global scale and help shape the future of Microsoft's AI infrastructure.
