Fivetran is looking for a Senior Software Engineer to join our Database Connector team. This team builds and operates the core replication technology that powers reliable, scalable data movement for enterprise customers. This role is a strong fit for engineers who enjoy working close to database internals, change data capture, replication correctness, and large-scale distributed systems. You will lead the design and evolution of connector capabilities, investigate complex replication behaviors, and help shape the technical direction of systems that support mission-critical workloads, including large Oracle deployments.

• Relational databases and database internals
• Docker, Bazel, Buildkite
• GCP, AWS, Azure
• Linux, Unix, Windows, git

• Design, build, and improve database connectors with a focus on correctness, performance, scalability, and operability.
