Senior Staff Software Engineer - Voltron Data

Senior Staff Software Engineer
Voltron Data | US Remote

At Voltron Data, we’re building the future of composable data systems—fueled by open standards, next-gen hardware, and the Apache Arrow ecosystem. We’re looking for a Senior Staff Software Engineer to push the boundaries of data infrastructure and lead the development of high-performance, distributed, and scalable systems.

What You’ll Do

• Design, build, and optimize core components of our Arrow-native query engine (Theseus), contributing to performance-critical data systems.

• Drive architectural decisions across C++, Arrow, Substrait, and related open standards.

• Collaborate with compiler, systems, and GPU engineers to accelerate workloads across heterogeneous compute environments (CPU, GPU, etc.).

• Own end-to-end feature delivery—from research to design to implementation to optimization.

• Lead RFCs and technical strategy in the open-source ecosystem (Arrow, Substrait, etc.), with a strong public footprint.

• Mentor other ICs across teams; serve as a technical multiplier without needing to manage people.

What Sets You Apart

• Proven track record as a senior IC working on modern compilers, databases, query engines, or similar systems.

• Strong background in systems programming (C++, Rust, Go); bonus for GPU computing or LLVM knowledge.

• Experience with Arrow, Parquet, Substrait, Velox, or similar ecosystems.

• Familiarity with vectorized query execution, columnar formats, or memory management optimization.

• Comfortable balancing bleeding-edge innovation with pragmatic engineering.

Nice to Have

• Contributions to open-source projects (especially Apache Arrow, Substrait, etc.).

• Experience in data interoperability standards and cross-language system design.

• Prior work in startup or high-growth environments where speed and rigor coexist.
