turquoise-health - Senior Performance Engineer, Data Products

• Own performance investigations across the product and data stack, moving from slow queries or poor user experiences to measurable root causes and production improvements • Design and evaluate data architecture changes • Partner with Product, frontend, and backend engineers to adapt product behavior to the characteristics of the underlying data through techniques such as request batching, debouncing, caching, pagination… • Develop representative benchmarks for important combinations of filters, datasets, and product workflows • Measure query latency, throughput, concurrency, and infrastructure consumption, with particular attention to datastore performance and cost (we use ClickHouse Cloud) • Evaluate the likely performance impact of upstream dataset changes before they reach production • Assess future product requests and recommend technical or product approaches that balance functionality, responsiveness, scalability, and cost • Prototype competing solutions, clearly communicate their tradeoffs, and validate the selected approach in production • Improve performance instrumentation, monitoring, and regression detection across data-powered product experiences • Establish reusable patterns and capabilities as the Data Product platform becomes a supporting layer for additional products and teams
