О компании и продукте

• You'll be our dedicated expert in query execution and query performance. That means owning the query execution service end-to-end: working on caching strategies, incremental execution, query rewrites, and other optimizations that directly affect the speed and cost of running Observe at scale. You'll also be the go-to resource when query latency issues arise during customer evaluations and new deal cycles, diagnosing root causes quickly and driving lasting fixes.
• This is a high-ownership, high-impact role. You'll partner closely with Snowflake's engineering and product teams to surface gaps and advocate for platform improvements that benefit Observe, and work across our backend systems to close performance gaps before they become customer problems.
• You'll excel here if you're equally comfortable doing rigorous performance analysis at scale (across millions of queries) and diving into the mechanics of a single slow query to find the fix.

Задачи

• Own and evolve the query execution service, including query caching, incremental execution, query rewrites, and decomposition strategies
• Systematically analyze large volumes of user and system-generated queries to identify performance bottlenecks and drive improvements
• Investigate and resolve customer-reported query latency issues, including acting as a first responder during new deal evaluations where query performance is under scrutiny
• Work on automated tuning of system parameters to reduce query execution times and costs
• Partner with Snowflake engineering and product teams to advocate for platform improvements, communicate requirements clearly, and drive resolutions
• Propose, scope, and deliver improvements to the query execution pipeline with attention to both short-term fixes and long-term architecture

Требования

• 5+ years of industry experience building distributed systems
• Hands-on experience working below the query interface, on the execution machinery itself (e.g., query planning, caching, rewrite rules, execution engines)
• Proven ability to diagnose and resolve database performance issues at scale, including both systematic analysis across large query populations and deep-dive debugging of individual cases
• Strong understanding of algorithms, distributed systems architecture, and backend infrastructure
• Ability to rapidly onboard to complex, unfamiliar systems and deliver meaningful improvements
• Customer-focused mindset: able to translate user-reported performance problems into technical root causes and durable fixes
• Strong communication skills for working with internal and external stakeholders (including partner engineering teams at Snowflake)

Будет плюсом

• Experience with Snowflake or other cloud data warehouses
• Prior work on observability, monitoring, or telemetry platforms
• Experience with OLAP query optimization, columnar storage, or vectorized execution
• Advanced degree in Computer Science with a focus on databases or systems
• Snowflake is growing fast, and we’re scaling our team to help enable and accelerate our growth
• We are looking for people who share our values, challenge ordinary thinking, and push the pace of innovation while building a future for themselves and Snowflake
• How do you want to make your impact?
