Senior C++ Software Engineer Data Engines at Voltron Data

At Voltron Data, we are redefining the foundation of data analytics by leveraging the power of Apache Arrow. As a venture-backed startup, we focus on building high-performance, accelerator-native data processing engines that utilize modern hardware to its full potential. We take pride in our open-source roots, with a team that includes long-term maintainers of the C++, Python, and R ecosystems. We are currently seeking a Senior C++ Software Engineer to join our remote team and contribute directly to Theseus, our composable data execution framework designed for petabyte-scale processing.

Key outcomes

• Develop, optimize, and maintain the core architectural components of our data execution framework.
• Master the internal mechanics of Apache Arrow, including compute primitives, query parsing, and memory management strategies like GPU-to-host spilling.
• Profile and debug distributed query executions to enhance overall system performance and scalability.
• Design and implement new relational algebra components to expand our SQL and DataFrame capabilities.
• Drive complex engineering initiatives, such as multi-query concurrency, multi-tenancy, and language-agnostic user-defined functions.
• Collaborate with our engineering team to improve fault tolerance, task scheduling, and resource management.

Requirements

• Extensive professional experience developing in C++.
• Proven expertise in building or maintaining data processing engines and distributed High-Performance Computing systems.
• Deep understanding of GPU and CPU resource management, including thread pools and memory allocation.
• Experience developing software for diverse hardware environments, including both CPU and GPU architectures.
• Familiarity with low-level networking or communication libraries such as UCX or libfabric.
• Practical experience contributing to open-source projects like Apache Arrow, Flight, Rapids, Velox, or Data Fusion.
• Proficiency in the English language.

Preferred qualifications

• Comprehensive knowledge of distributed, multi-threaded system design.
• Strong proficiency in SQL and an understanding of the computational abstractions behind non-SQL systems.

Compensation

The salary range for this position is $171,000.00 to $210,000.00, with final offers determined by individual experience, skills, and location. In addition to the base salary, this role is eligible for equity awards.
