FivetranSenior C Programmer
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 core team and perform a healthy mix of design and implementation tasks to advance the technical foundation behind the Fivetran product offering.
This team is tasked with evolving a high performance extract-load-trans form data integration system that enables our engineering teams to correctly implement hundreds of data connectors with minimal maintenance effort. The role will challenge you to reason about relational semantics, powerful abstractions, data representation, and software performance. You don’t need to be a subject matter expert before you join us (you will be one before you leave!), but you will need to have experience working carefully with a high impact software team — especially in environments where the best option may not be obvious, your decisions have cascading implications, and where you sometimes need to measure twice before you cut once. A successful candidate will be humble enough to collect diverse input and build consensus, will be experienced and confident enough to be decisive when it’s needed, and will be practical enough to build and iterate on the system while it’s in production. We are also looking for expertise and productivity with both modern and legacy software development environments.
This is a full-time position based out of our Dublin 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.

- Review and approve pull requests
- Care and feel ownership of our product, and leverage your skills towards improving it
Skills We’re Looking For
- You are execution-oriented, and understand the need to target your “innovation budget” for the greatest impact: you find the middle ground between “perfect, but takes forever to code” and “fixes it now, but nobody will ever be able to understand what I did”
- You know how to design and code systems and software that is effective, intuitive, easy-to-operate, and elegantly simple
- You have worked with the relevant tooling and techniques: cloud services, network protocols, serialization, relational databases, etc.
- You have knowledge of complex structures, object orientation, exceptions, memory management techniques.
Bonus Skills
- Experience with data replication, ETL/ELT tools, cloud and software defined infrastructure tools (for instance AWS Cloud Formation, Kubernetes, Docker), API technologies and analytics is definitely a plus
- Knowledge of DBMS internals is a strong plus
- Familiarity with low level concepts, such as encoding and the internals of network communication, is a strong plus
- Familiarity with system level programming (such as process and memory management and inter-process communication) is a plus
