About the role

Principal Software Engineer I to build next-generation experimentation and configuration infrastructure with an AI-first approach, enabling faster, safer innovation and higher developer productivity at Snowflake.

Responsibilities

  • Architect and build distributed infrastructure. Design scalable configuration and feature-flag services with low-latency evaluation, clear consistency guarantees, fault isolation, and predictable behavior during failures.
  • Make a safety scale with change velocity. Build automated validation, targeted exposure, progressive rollouts, health-based guardrails, and dependable rollback. Reduce manual coordination while making changes observable, auditable, and recoverable.
  • Advance experimentation. Partner with engineering and data science teams to build reliable assignment, exposure tracking, and measurement infrastructure that helps teams evaluate changes and make evidence-based decisions.
  • Build and work AI-first. Make AI integral to how you design, implement, test, and operate software. Embed AI-powered capabilities into the platform for configuration discovery, risk assessment, rollout planning, and impact analysis. Establish rigorous evaluation, security, and reliability standards for these capabilities, and drive adoption of AI-first practices across the team.
  • Lead from architecture through adoption. Translate ambiguous needs into practical designs and milestones. Deliver intuitive APIs, libraries, and self-service tools; guide incremental migrations and simplify the full lifecycle from flag creation to retirement.
  • Raise the engineering bar. Write and review production code, diagnose complex failures, own operational outcomes, and mentor engineers. Influence across teams through technical depth, clear communication, and sound judgment.

Qualifications

  • 12+ years of software engineering experience, including technical leadership of complex backend or infrastructure initiatives spanning multiple teams.
  • Deep experience designing, building, and operating large-scale distributed systems, with strong understanding of concurrency, consistency, caching, failure recovery, and performance.
  • Strong computer science fundamentals and hands-on proficiency in Java, Go, C++, or a comparable backend language, plus experience with AWS, Azure, or Google Cloud.
  • An AI-first engineering practice: actively use AI throughout the software lifecycle and demonstrate how it improves execution, problem-solving, and quality; ready to build AI-powered platform capabilities and help others adopt this approach.
  • Track record of turning ambiguous problems into delivered systems, balancing architectural investments with incremental progress, and driving adoption across engineering organizations.
  • Clear written communication, low-ego collaboration, strong ownership, and experience mentoring senior engineers.
  • A degree in Computer Science or a related field, or equivalent practical experience.
  • Especially relevant: Experience with feature-flag or configuration platforms, distributed control planes, progressive delivery, experimentation infrastructure, or AI-powered developer tools.
