- Work with the platform team to improve performance, reliability, and scalability.
- Debug and resolve complex query execution issues in production environments.
WHAT WE'RE LOOKING FOR
- At least 5 years of experience in data infrastructure, query engine development, distributed systems, or database query processing.
- Experience building or maintaining query compilers, optimizers, or execution engines.
- Background with graph databases or graph query languages.
- Experience shipping distributed query processing across multiple data sources, including federated execution across heterogeneous systems.
- Proficiency in C++, Rust, or Java, with knowledge of SQL, query optimization, or compiler design.
- Experience optimizing query performance in high-volume or latency-sensitive environments, and familiarity with Snowflake, Databricks, or Oracle.

About this listing
Published on Ashby under the board identifier Clera, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.
RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
