• Build out the backend for Pinner-facing features to power the future of inspiration on Pinterest

• Partner with design, product, and backend teams to build end-to-end functionality

• Put on your Pinner hat to suggest new product ideas and features

• Employ automated testing to build features with a high degree of technical quality, taking responsibility for the components and features you develop

• Experience in Python, Java, C++, or Go or another language and a willingness to learn

• Demonstrated ability to use AI to improve speed and quality in your day-to-day workflow for relevant outputs.

• Strong track record of critical evaluation and verification of AI-assisted work (e.g., 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.

• Bonus points if you have experience with any of the following (needs vary from team to team): Developer Enablement/Productivity or Internal Tooling, CI/CD, Generative AI/LLMs, Spark/Flink/Big Data technologies, Data Science/Analytics, Building Products or Internal Tools from Scratch
