Principal Software Engineer - Parameters & Experimentation

AS A PRINCIPAL SOFTWARE ENGINEER AT SNOWFLAKE YOU WILL

• 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.
