Software Engineer III at Fivetran building data pipelines and Reverse ETL products. Role spans backend systems, APIs, and UI components using Ruby on Rails, TypeScript, and AWS. Includes mentoring and cross-team collaboration.
From Fivetran’s founding until now, our mission has remained the same: to make access to data as simple and reliable as electricity. With Fivetran, customer data arrives in their warehouses, canonical and ready to query, with no engineering or maintenance required. We’re proud that more organizations continue to leverage our technology every day to become truly data-driven.
About the Role
Fivetran is building data pipelines to power the modern data stack for thousands of companies.
We’re looking for a senior software engineer to join our Reverse ETL experimental engineering team.
We are a small, flexible team that works on experimental initiatives in the Reverse ETL group (formerly Census). Our team has built our most experimental products, from Census Embedded, to SaaS ingest pipelines, and Entity Resolution product.
Today, our work spans two areas: helping engineers and non-engineering partners such as PMs and CSEs scale their workflows with AI, and supporting the integration of Census into Fivetran through efforts such as migrating observability from Datadog to Grafana.
This is a full-time position based out of our Toronto 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
Expertise in at least one interpreted language such as Python or Ruby.
Hands-on experience with at least one compiled language such as C++, Kotlin, Scala, Go, Java, etc.
Solid understanding of relational databases (experience with data warehousing solutions (e.g., Snowflake) is a bonus)
Proven experience in system integration, including API consumption and development (experience with infrastructure management is a bonus)
Familiarity with leading cloud providers, such as GCP, AWS, or Azure
What You’ll Do
Make contributions to all parts of our tech stack, which comprises Ruby on Rails, Typescript, Vue, and AWS.
Be comfortable “filling in the gaps” in product / design specs. The prospect of being able to prototype to test ideas out before committing to building is exciting to you.
Work closely with our product team, leaders, and customers to help design and develop features that make Fivetran the one-stop shop for data activation.
Mentor early-career engineers, perform thoughtful and constructive code reviews, advise on best practices, provide project-level leadership, operate across teams, departments, and time zones.
Lead major projects, from driving research spikes, to writing and socializing design documents, to planning the implementation and rollout
Skills We’re Looking For
Can build things end-to-end. Our engineers build, deploy and maintain their code.
Is adept with data, backend systems, APIs, and UI components.
Is customer-focused, with an eye for building delightful product experiences and developer experiences.
Approaches new problems with a scrappy optimism, with a bias towards action.
Thrives in ambiguous environments where you get to work directly with customers and make decisions that build trust and have a huge impact on the business.
Comfort using AI-assisted development tools such as Claude Code, Cursor, or GitHub Copilot to prototype, debug, automate workflows, and move faster while maintaining strong engineering judgment.
This role represents new headcount added to the team to support continued growth and expansion of capabilities.
