Senior Software Engineer, Foundations

About the role

As a member of our Foundations team, you'll independently own well-scoped, meaningful projects that improve the reliability and performance of Peregrine's data platform; the systems that ingest, process, and enrich large volumes of customer data from a wide variety of sources, at high scale and low latency. You'll work within our datastores, orchestrated data pipelines, and the connection, authorization, and notification layers that keep the entire system efficient and secure — extending existing architectural patterns and proposing new ones where they're needed.
