We are looking for a Staff Software Engineer to help improve the quality and velocity of data science at Pinterest. You will shape the future of the people-facing and business-facing products we build by creating rock-solid data foundations and tooling, and by leading a high-performance team that partners closely with our Core Data Science organization. What you'll do: - Lead by example, and mentor a diverse team of analytics engineers with an inclusive culture. - Develop best practices for instrumentation and experimentation and communicate those to product engineering teams.

- Build and prototype AI tools and analysis pipelines iteratively to provide insights at scale while developing comprehensive knowledge of data structures and metrics, advocating for changes where needed. - Use AI to accelerate analysis, prototyping, and iteration—drafting pipelines, exploring approaches, and automating repeatable documentation and QA—while applying judgment and verification to ensure correctness and quality. - Work closely with Data Scientists and Engineers to build tools and processes that enable self-service of key datasets, insights, and metric investigations. - Contribute to comprehensive documentation of tools and datasets, and drive the strategy for better data quality and data democratization within Pinterest. - Work cross-functionally to build and communicate key insights, collaborating with product managers, engineers, designers, and researchers to help build the next experiences on Pinterest. What we're looking for: - 6+ years of experience working with data in a fast-paced, data-driven environment. - Ability to manipulate large data sets with high dimensionality and complexity; fluency in SQL (or other database languages) and a scripting language (Python or R), including nested data structure manipulation, windowing functions, query optimization, and data partitioning techniques. - Experience conducting workflow orchestration and ETL/ELT with huge, complicated datasets and handling DAG data dependencies. - Consistent track record of supplying analytics solutions to existing teams, with the ability to take open-ended goals and scope them into defined, impactful objectives. - A team player able to partner with cross-functional leadership to quickly turn insights into actions, and an accountable operator who proactively identifies project opportunities amid competing priorities. - Demonstrated ability to use AI to improve speed and quality in your day-to-day workflow, with a strong track record of critical evaluation and verification of AI-assisted work (testing, source-checking, data validation, peer review). - High integrity and ownership: you protect sensitive data, avoid over-reliance on AI, and remain accountable for final decisions and deliverables.
