Staff Software Engineer

About the Role

Fivetran is looking for a Staff 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.

This is a full-time position based in our Toronto, Canada office. Our hybrid work model offers a blend of remote flexibility and in-person collaboration, including two days in the office each week to connect and build as a team.

Technologies You’ll Use

• Java, C/C++, SQL
• Relational databases and database internals
• Docker, Bazel, Buildkite
• GCP, AWS, Azure
• Linux, Unix, Windows, git

What You’ll Do

• Design, build, and improve database connectors with a focus on correctness, performance, scalability, and operability.
• Investigate complex replication and CDC issues in production systems used by enterprise customers.
• Analyze low-level database behavior, logs, and transaction flows to support new features and improve reliability.
• Develop support for new database capabilities, especially in Oracle and other enterprise database platforms.
• Drive software design and technical roadmap decisions for the team.
• Improve observability, testing, and operational excellence across connector systems.
• Partner with engineers across teams to raise architecture quality and reliability across the broader platform.
• Mentor engineers and provide technical leadership through design reviews, implementation guidance, and hands-on development.

What We’re Looking For

• Significant hands-on software engineering experience building backend, infrastructure, or distributed systems.
• Strong experience with Java and/or C/C++ in production systems.
• Deep understanding of database internals, transaction semantics, query behavior, and data consistency.
• Experience building or maintaining data replication, CDC, ETL/ELT, migration, or connector systems.
• Experience investigating low-level or poorly documented system behavior, such as binary logs, protocols, storage formats, or APIs.
• Strong system design skills, especially for reliable distributed systems operating under strict correctness and availability requirements.
• Ability to lead technical direction and influence architecture across teams.
• Strong communication skills and a track record of mentoring engineers.

Bonus Skills

• Experience with Oracle internals, redo/archive logs, or log-based replication.
• Experience with database migration or replication products.
• Experience in systems-level engineering, including kernel, drivers, networking, or protocol analysis.
• Experience working on developer infrastructure or highly reliable data platforms.

This role represents new headcount added to the team to support continued growth and expansion of capabilities.
