Position Title

Senior Software Engineer – Core Databases

About Us

From Fivetrans 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. Were proud that more organizations continue to leverage our technology every day to become truly data-driven.

Fivetran and dbt Labs are bringing together two industry-leading companies with a shared mission: helping organizations unlock the full value of their data. Together, were delivering the data infrastructure layer that helps organizations move, transform, and trust their data from the moment data moves, through every transformation, to the context teams and AI systems rely on. Fivetran helps organizations automate data movement across the systems, clouds, engines, and tools they rely on. dbt Labs pioneered analytics engineering, helping teams transform data into reliable, governed insights. Together, we support thousands of organizations as they build a trusted foundation for analytics, AI, and better business decisions. As we bring our teams and technology together, were building on the strengths of both companies while continuing to deliver the products and experiences our customers know and trust. Its an exciting time to join us: were creating a company with the scale, talent, and technology to help more organizations put their data to work with greater speed, confidence, and impact. During this transition period, you may see references to both Fivetran and dbt Labs throughout our recruiting process as we integrate our teams, systems, and career sites.

About the Role

Fivetran is building data pipelines to power the modern data stack for thousands of companies. 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.

• C (our main language), Python (used in testing), relational databases (Postgres, Oracle, SQL Server), make

• 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

Skills Were 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
