Staff Software Engineer_Fusion Adapters

Location: Bengaluru, Karnataka, India, APAC 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 Us 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, we’re 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, we’re building on the strengths of both companies while continuing to deliver the products and experiences our customers know and trust. It’s an exciting time to join us: we’re 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 dbt Fusion is building the next generation of data execution and connectivity infrastructure, enabling dbt workloads to run efficiently across diverse compute engines and data platforms. As a Senior Engineer on the Fusion Adapters and Connectivity team, you’ll design and ship core abstractions powering how dbt communicates with execution systems — leveraging Rust, Go, Arrow, and emerging open standards. This is a rare opportunity to work at the intersection of systems programming, database internals, and high-visibility open-source development. Your work will shape a foundational platform leveraged across the dbt ecosystem and the broader data community. What You’ll Do Design, build, and maintain Rust-first connectivity layers, execution APIs, and adapter scaffolding. Partner with teams building the dbt compiler, semantic layer, and runtime to evolve adapter interfaces and system boundaries. Contribute to Arrow/ADBC and other open-source specifications or implementations, strengthening the data ecosystem. Own CI, testing frameworks, profiling, error reporting surfaces, and release readiness for Fusion adapters. Debug complex interoperability and performance issues across drivers, engines, and compute domains. Collaborate with internal and community maintainers to review PRs, write RFCs, and evolve public code architectures. Mentor engineers on systems best practices and contribute to shared patterns around resilience, debuggability, and API clarity. Skills We’re Looking For Strong programming background in Rust, Go, C++ or similar performance-oriented languages. Experience designing or maintaining SDKs, libraries, connectors, or compute/data integration codebases. Exposure to data warehouses, query engines, Arrow/columnar ecosystems, or execution runtimes. A desire to build foundational platform components that other teams and community members rely on. Comfort working in public code review loops, async-first communication, and collaborative RFC processes. A mindset grounded in debuggability, reliability, and ownership in ambiguous problem spaces. You’ll have an edge if you have: Contributed to or interacted with Arrow, ADBC, DuckDB, Presto, DataFusion, Spark, ClickHouse, or similar engines. Experience shaping adapter/plugin standards, driver contracts, or architectural interfaces used by others. Familiarity with Rust async ecosystems (tokio, tower, tracing) or Go concurrency practices. Prior OSS governance experience — triaging issues, reviewing PRs, or working with community maintainers. An interest in building developer-experience layers or scaffolding frameworks for adapter authors. Qualifications: 6+ years experience in software engineering, with strong systems-level skills. 2+ years working in open-source, SDK, runtime, or low-level integration environments. Bachelor’s degree in Computer Science / related field or equivalent experience through industry OSS contributions. #LI-REMOTE #LI-SA1 Perks and Benefits 100% employer-paid medical insurance * Generous paid time away from work, including paid vacation or flexible/unlimited vacation depending on role and country, plus paid sick time, inclusive parental leave, paid holidays, including a year-end Global Week of Rest, and volunteer days off.
