Senior​/Principal Software Engineer CoreAI

Position: Senior/Principal Software Engineer - Growth (CoreAI)
Overview

About the Role

* We're building AI‑first engineering systems that power growth at Microsoft - designing, shipping, and scaling code that directly shapes how millions of developers experience and adopt AI.

* As a Growth Engineer in CoreAI, you'll sit at the intersection of product, engineering, and data, driving experimentation, learning velocity, and real business impact across world‑class developer and AI products.

* This role is about shipping fast, learning faster, and scaling what works - all while upholding Microsoft's commitment to responsible, inclusive, and trustworthy AI.

About CoreAI

* CoreAI - Platform and Tools is Microsoft's AI‑first engineering organization, created to build the end‑to‑end Copilot & AI stack powering products like Git Hub Copilot and Visual Studio Code.

* Our mission is to empower every developer to shape the future with AI, accelerating how AI applications are built, deployed, and improved at global scale.

Why This Role Is Exciting

* This is not growth at the edges - this is growth at the core.

* Build AI‑powered growth loops on world‑class products like VS Code and Git Hub

* Operate inside a high‑velocity, AI‑first engineering organization where learning speed matters

* Influence how hundreds of millions of users discover, adopt, and succeed with AI

* Drive real business impact - measured, shipped, and scaled

* Help define what responsible growth looks like in the AI organisation

Our Culture & Values

* At Microsoft, how we build matters as much as what we build.

* We are guided by our mission to empower every person and every organization on the planet to achieve more, and we show up every day with:

* A growth mindset

* Respect, integrity, and accountability

* A commitment to inclusive, responsible AI that earns trust and benefits everyone

* We believe diverse perspectives make our products - and our teams - stronger.

Impact You'll Have

* Raise the bar for experimentation quality across CoreAI

* Help define AI growth best practices for Microsoft

* Turn learning into leverage - faster adoption, better experiences, measurable results

Responsibilities

What You'll Do

* Own growth through engineering excellence and experimentation

* Design, ship, and iterate on growth experiments across acquisition, activation, engagement, and retention

* Build and evolve A/B testing frameworks, metrics, and tooling that raise experimentation quality and confidence

* Use data and telemetry to guide decisions - from experiment design to rollout strategy

* Scale successful growth patterns across high‑traffic, global AI products

* Balance speed and rigor in a fast‑paced, AI‑first engineering environment

What We're Looking For

* Software engineering fundamentals with experience building, shipping, and operating production services or client applications

* Proficiency in designing scalable, reliable systems that support rapid iteration and experimentation

* Experience writing high‑quality, maintainable code and owning services end‑to‑end in a live environment

* Ability to reason about performance, reliability, and correctness in high‑traffic systems

* Experience supporting or driving experimentation (A/B testing) in production environments

* Understanding of experimentation quality, including guardrails, metrics selection, and rollout strategies

* Engineering mindset grounded in hypothesis‑driven development and learning through iteration

Qualifications
