Job Description:

Microsoft is at the forefront of a new era in productivity, and Microsoft 365 Copilot is redefining how we build and deliver AI experiences. We are a small, focused team within MSAI Office of the CTO (OCTO) committed to driving Copilot Agility — accelerating how we innovate, build, and scale the Copilot platform across Microsoft. We are looking for a Senior Software Engineer who is passionate about developer agility and improving the speed, reliability, and efficiency of Copilot development. In this role, you will design and build backend, data, and ML systems that empower teams across E+D(M365 Core, OPG, GXP, etc) to develop and deploy Copilot capabilities with greater velocity and confidence. You’ll partner closely with other engineers, product managers, and applied scientists to identify bottlenecks, improve workflows, and deliver key initiatives such as the Copilot Data Platform.

Job Responsibility:

Design and implement scalable backend system, data pipelines and evaluation infrastructure to accelerate Copilot development and other agility-related initiatives
Collaborate closely with cross-functional partners — including product managers, applied scientists, and data engineers — to deliver high-impact features and platform improvements
Drive engineering standard practices across the team, contributing to reliability, maintainability, and developer efficiency
Contribute to the technical direction and roadmap by identifying opportunities to improve agility, speed, and developer experience across Copilot systems
Participate actively in code reviews, design discussions, and sprint planning, helping the team deliver with velocity and quality
Embody our culture and values

Requirements:

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, C++, C#, Java, JavaScript, or Python
OR equivalent experience
1+ years experience designing, implementing, and operating backend and data-intensive or ML-driven and evaluation systems
Demonstrated ability to ramp up quickly, work independently, and make measurable impact in fast-paced and ambiguous environments
Solid collaboration skills and ability to work effectively across multiple teams and disciplines to deliver complex projects
Ability to meet Microsoft, customer and/or government security screening requirements are required for this role
Microsoft Cloud Background Check: This position will be required to pass the Microsoft Cloud background check upon hire/transfer and every two years thereafter

Nice to have:

Experience working with SOTA AI tooling to accelerate software development lifecycle
Experience with Azure platforms and modern deployment practices such as CI/CD, containerization, and microservices
Understanding of developer productivity and agility principles, including automation, observability, and workflow optimization
Proven track record of improving engineering velocity and reliability through tooling, infrastructure, or process enhancements
Familiarity with data engineering, semantic search, or ML model serving is a plus
A growth mindset, passion for continuous learning, and drive to make both systems and teams more efficient and effective
