Were 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 dont 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 its needed, and will be practical enough to build and iterate on the system while its 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 Novi Sad office. Our hybrid work model offers a blend of remote flexibility and in-person collaboration. Technologies Youll Use * C (our main language), Python (used in testing), relational databases (Postgres, Oracle, SQL Server), make * GitHub Copilot, Claude Code, Jenkins, GCP , Azure, AWS * macOS/Linux/Unix/Windows, git What Youll Do * Learn deeply about Fivetran in order to focus development on practical and relevant system improvements * Contribute to the development and planning of our roadmap * Collaborate with a small but mighty core team, and with a broader set of stakeholders * Work across the project lifecycle: requirements, design, prototype, implementation, review, release, monitoring * Review and approve pull requests * Care and feel ownership of our product, and leverage your skills towards improving it, We are committed to ensuring that all candidates have an equal opportunity to participate in our interview process. If you require accommodations at any stage of the process due to a disability, medical condition, or any other circumstance, please don't hesitate to submit your request by filling out this form.
