About the role

Senior technical leader for Streamlit in Snowflake (SiS), shaping platform architecture, developer experience, and scale across the Streamlit in Snowflake product.

Responsibilities

  • Define and own the architectural vision for the SiS platform spanning the SPCS container runtime, the warehouse runtime, the embedding SDK, developer tooling, and the Snowsight integration layer.
  • Drive the platform's evolution toward next-generation capabilities building on features like chromeless viewer URLs and IdP integration, and shape architectural direction for areas in development.
  • Serve as the primary technical representative for SiS in company-wide architecture forums, shaping Snowflake's broader app platform strategy.
  • Establish engineering standards for performance, reliability, and scale to support many concurrent users with fast startup times and high availability.
  • Lead the technical design and review process for high-stakes, cross-functional initiatives with infrastructure, Snowsight, Cortex/AI, security, and the open-source Streamlit project.
  • Be a strong hands-on contributor by authoring specs, implementing changes, reviewing PRs, and setting high bars for code quality, API design, and system architecture.
  • Mentor and grow senior engineers on the team; identify and incubate the next generation of technical leaders.
  • Partner with Product and Design to drive the roadmap and translate customer needs into robust engineering solutions.
  • Advocate for SiS developers and end users by balancing developer experience with enterprise scalability.

Qualifications

  • 15+ years of software engineering experience, with a track record of architecting and shipping production-grade developer platforms or application runtimes.
  • Strong expertise in Python application runtimes, server-side frameworks, and distributed execution environments with performance, reliability, and lifecycle management at scale.
  • Strong understanding of container-based execution environments (Docker, Kubernetes, SPCS or similar) and their tradeoffs.
  • Hands-on experience designing and evolving developer-facing SDKs, embedding APIs, or component libraries with API versioning and backward compatibility.
  • Demonstrated ability to lead technical programs spanning multiple teams and organizational boundaries without direct authority.
  • Experience with enterprise SaaS reliability requirements: multi-tenancy, scale, security review processes, and graceful migrations.
  • Familiarity with the open-source Streamlit framework or similar Python-based app frameworks is a strong plus.
  • Experience working with IdP integrations, OAuth flows, or authentication systems for embedded/public-facing web applications is a plus.
  • Nice to have: Familiarity with the web platform (TypeScript/JavaScript, browser APIs, WebSockets, service workers, iframe/cross-origin security models) as it relates to serving Python-backed apps in the browser.
