Overview
We’re building AI‑first growth and experimentation systems that scale across Microsoft. This role is about designing foundational engineering systems (instrumentation, experimentation, rollout, and decisioning) that let teams ship, measure, learn faster with higher confidence.
As a Principal Growth Engineer in CoreAI, you’ll drive the technical strategy for how we measure, experiment, and scale AI experiences across world‑class products — while remaining deep in the details and landing meaningful changes daily.
At this level, impact comes from building repeatable systems and raising the engineering bar: better experiment quality, better telemetry, safer rollouts, and clearer business outcomes — delivered through pragmatic execution and deep technical judgment.
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.
Responsibilities
Architect and build paved paths for online experimentation: standardized metrics, guardrails, analysis workflows, and rollout automation that improve reliability and decision quality across teams
Lead multi‑workstream initiatives that span teams/products (e.g., unified growth measurement, cross‑surface funnels, experimentation quality improvements)
Build and evolve core capabilities: telemetry foundations, experiment assignment/targeting, feature flighting, and risk controls (kill‑switches, guardrails, progressive delivery)
Partner with Product, Data Science, Design, and Research to turn ambiguous goals into shippable, measurable systems
Demonstrated technical leadership across architecture, service fundamentals, and quality (reliability, performance, operability, security, and maintainability)
Track record of translating ambiguous product/business problems into measurable engineering outcomes, with clear hypotheses, instrumentation, and decision criteria
Qualifications
Required Qualifications
-
Bachelor's Degree in Computer Science or related technical field AND 8+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience.
Other Requirements
Preferred Qualifications
8+ years building and shipping high‑availability features for multi‑region, globally distributed systems (resiliency, failover, capacity planning)
4+ years of experience in experimentation with emphasis on quality: guardrails, bias detection, metric integrity, rollout risk management, and enterprise grade experimentation
Demonstrated experience building experimentation/measurement platforms (feature flags/flighting, assignment, metrics pipelines, analysis tooling) used by multiple teams
Demonstrated experience leaning heavily on AI to accelerate engineering velocity, including using AI tools to prototype, implement, debug, and iterate on production systems
