Principal Software Engineer Growth (CoreAI)

About the Role

• Were building AIfirst 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 youll drive the technical strategy for how we measure experiment and scale AI experiences across worldclass 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.

About CoreAI

• CoreAI Platform and Tools isMicrosofts AIfirst engineering organization created to build the endtoend Copilot & AI stack powering products like GitHub 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 atglobalscale.

What Youll Do

• Own growth through engineering excellence and experimentation at a systems level

• 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 multiworkstream initiatives that span teams/products (e.g. unified growth measurement crosssurface funnels experimentation quality improvements)

• Build and evolve core capabilities: telemetry foundations experiment assignment/targeting feature flighting and risk controls (killswitches guardrails progressive delivery)

• Partner with Product Data Science Design and Research to turn ambiguous goals into shippable measurable systems

• Stay close to the work: write production code review designs/PRs and coach others through architecture and implementation tradeoffs

What W ere Looking For

• Proven ability to design and ship systemic solutions (platforms frameworks primitives) that enable multiple teams to move faster while remaining deeply handson and detailoriented

• S oftware engineering fundamentals with experience building shipping and operating production services or client applications at scale

• 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

• High data aptitude: comfortable with metrics telemetry and experimental analysis and able to raise the bar on experimentation rigor and interpretation

Required Qualifications

• Bachelors 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

• 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

• 8 years building and shipping highavailability features for multiregion 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

• C rossteam influence: you create clarity align stakeholders and drive execution across organizational boundaries without becoming a piecemover
