Original Job Description

Overview

Microsoft AI Asia Platform Team builds the foundational infrastructure powering Microsoft’s AI products across Azure, Copilot, Bing, and internal engineering systems. We develop enterprise-grade Agent Runtime, large-scale model training/serving frameworks, and next-generation AI developer toolchains. Our infrastructure directly impacts how millions of developers build and deploy AI applications globally.

We are seeking a Software Engineer 2 with solid multi-language programming capabilities to build high-performance, reliable infrastructure for Agent systems. You will work on the core runtime for autonomous agents, distributed LLM serving, and RL-based training pipelines—turning cutting-edge AI research into production-grade platform services.

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.

Starting January 26, 2026, Microsoft AI (MAI) employees who live within a 50- mile commute of a designated Microsoft office in the U.S. or 25-mile commute of a non-U.S., country-specific location are expected to work from the office at least four days per week. This expectation is subject to local law and may vary by jurisdiction.

Responsibilities

• Agent Runtime Development: Design and implement high-throughput runtime systems supporting Tool Use, Function Calling, and multi-agent orchestration at scale

• LLM Serving Infrastructure: Optimize inference stacks including request scheduling, KV cache management, continuous batching, speculative decoding, and model parallelism

• AI Developer Tooling: Develop AI-assisted development tools and applications (similar to Claude Code, OpenClaw) to boost engineering / work productivity

• Platform Abstraction: Transform experimental agent capabilities into reusable platform APIs, SDKs, and managed services for upstream product teams

Qualifications

Required Qualifications:

• Bachelor’s Degree in Computer Science or related technical field AND 2+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python

• OR equivalent experience.

• Solid multi-language programming and vibe-coding proficiency: Production-level experience with Rust, C++, C#, and Python (expertise in at least two required, familiarity with all four preferred)

• Systems engineering fundamentals: Deep understanding of concurrency, memory management, performance optimization, and distributed systems architecture

• Agent architecture knowledge: Solid grasp of modern agent paradigms (ReAct, CoT, Function Calling, Agent State Management) with hands-on implementation experience

• LLM infrastructure foundation: Understanding of Transformer inference mechanics, experience with serving frameworks (vLLM, TensorRT-LLM, Triton, or custom stacks).

Other Requirements:

Ability to meet Microsoft, customer and/or government security screening requirements are required for this role. These requirements include but are not limited to the following specialized security screenings:

Microsoft Cloud Background Check : This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter.

Preferred Qualifications:

• RL Training Experience: Hands-on experience with RLHF, DPO, PPO, or offline RL for language model alignment;

• High-Performance Deployment: Expertise in model quantization (GPTQ/AWQ/GGUF), compiler optimization (MLIR/TVM), or heterogeneous hardware acceleration (GPU/TPU/NPU).

• Agent Systems Depth: Contributions to open-source agent frameworks (LangGraph, AutoGen, OpenHands, CodeR) or deep technical analysis of Claude Code/ OpenClaw implementations.

• Cloud-Native Engineering: Experience building services on Kubernetes, service mesh architectures, or Azure/GCP/AWS platforms at scale.
