Software Engineer II

Technology, Data & Digital · Software & Web Development · Software Engineering

In short

Microsoft is hiring a Software Engineer II to join their AI incubation team, focusing on rapid prototyping of sales agents using LLMs and Azure technologies. This full-time hybrid role involves turning agent ideas into working prototypes, building agent skills, and evaluating AI model performance in close collaboration with a Principal engineer.

Responsibilities

Turn new agent ideas into working prototypes in days, partnering closely with a Principal engineer, PM, and design from first demo through seller pilot.
Build agents, multi-step workflows, and MCP servers that connect to real seller and customer context in Dynamics 365, Dataverse, Microsoft Graph, and internal sales systems.
Write reusable agent skills, tools, and plugins for Microsoft 365 Copilot and other agent hosts, and contribute them back to our shared platform.
Build lightweight evaluations for your prototypes (golden sets, LLM-as-judge scorers, traces) and report quality, latency, and cost so the team can decide what to scale and what to stop.
Harden the prototypes that prove out with tests, telemetry, authentication, and Responsible AI review, and help hand them off to production surfaces such as Sales Home.
Write short design notes, demo your work to the team and leadership, and share what you learn about new models and agent tooling.
Take part in code and design reviews, and share on-call (DRI) duty for the pilots and services you help ship.

Requirements

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.
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.

Desired Qualifications

Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, C#, TypeScript, JavaScript, Python, or Java OR Master's Degree in Computer Science or related technical field AND 3+ years technical engineering experience with coding in languages including, but not limited to, C#, TypeScript, JavaScript, Python, or Java OR equivalent experience.
Hands-on experience building applications with large language models (for example prompt design, tool or function calling, retrieval-augmented generation, or agent frameworks), whether in production, internal tools, open source, or substantial personal projects.
Experience building or integrating Model Context Protocol (MCP) servers, or exposing APIs and data to agents as tools.
Experience with one or more agent frameworks or platforms, such as Microsoft Agent Framework, Semantic Kernel, AutoGen, Microsoft Foundry, Copilot Studio, Microsoft 365 Agents SDK, LangGraph, OpenAI Agents SDK, or Claude Agent SDK.
A track record of building fast: hackathon projects, MVPs, demos, or internal tools that went from idea to working software in days, ideally including one that reached real users.
Range across the stack: a back-end API, a simple React/TypeScript front end, and deployment of both to Azure, AWS, or GCP.
Experience evaluating LLM output, such as building small golden datasets, LLM-as-judge scoring, comparing prompts or models, or tracing agent runs (for example with OpenTelemetry).
Working knowledge of Responsible AI practices in real projects: grounding, content safety, prompt injection defenses, and PII handling.
Daily, fluent use of AI coding tools (for example GitHub Copilot, Claude Code, or Cursor) in your development workflow.
Familiarity with Dynamics 365, Dataverse, Microsoft Graph, Power Platform, or CRM systems such as Salesforce, and an interest in sales or customer-facing products.
