This will involve implementing and iterating on experiments end-to-end, partnering with Product and Data Science to ideate, launch, measure, and refine A/B tests that move key metrics. You'll also identify and execute codebase and product optimizations that improve reliability, performance, and cost efficiency across distributed systems. Additionally, you'll collaborate cross-functionally to define roadmaps, success metrics, and guardrails; communicate tradeoffs clearly in a fast-paced, experiment-driven environment. You'll uphold high engineering standards through code reviews, testing, documentation, and thoughtful architecture decisions that balance speed with quality.

You should have a strong working knowledge of relational databases (e.g., PostgreSQL, MySQL) and caching/NoSQL stores (e.g., Redis, DynamoDB); ability to write and optimize SQL. Experience collaborating with Product and Data Science to build data-informed features and iterate based on experiment results is also essential. You should also have experience deploying and operating services on a public cloud (e.g., AWS, GCP) and working with containers (e.g., Docker, Kubernetes) or similar orchestration.
