Staff Software Engineer_Fusion Adapters

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.

Responsibilities

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

Requirements

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; 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

Nice to 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

Benefits

100% employer-paid medical insurance; Generous paid time-off policy (PTO), plus paid sick time, inclusive parental leave policy, holidays (including a year end Global Week of Rest), and volunteer days off; RSU stock grants; Professional development and training opportunities; Company virtual happy hours, free food, and fun team-building activities; Monthly cell phone stipend; Access to an innovative mental health support platform that offers personalized care and resources in areas such as: therapy, coaching, and self-guided mindfulness exercises for all covered employees and their covered dependents
