Job Description:

Voltron Data is an early-stage company creating high-performance data access and in-memory computing tools based on Apache Arrow to accelerate enterprise data analytics. We are a collection of open-source maintainers who have been driving open-source ecosystems over the last 15 years, particularly in the C++, Python, and R programming ecosystems.

We are assembling a global, diverse team to build a new foundation for data analytics with Apache Arrow. This foundation will usher in a wave of innovation in data processing that can take full advantage of the speed and efficiency offered by modern hardware.

We are looking for a highly motivated Senior or Principal C++ Software Engineer for Data Engines, you'll have the opportunity to work directly on data execution engines that bring compute into the heart of the Apache Arrow project. You will work closely with Voltron Data development teams to develop data analytics tools to improve modularity and composability. You will be maintaining, optimizing and implementing new features with a strong focus on performance, scalability and stability to improve data engines' efficiency at all scales.

Upon Joining:

  • Spending time learning about the Apache Arrow compute primitives, compute intermediate representation, query parser and optimizer and other foundational components.
  • Diving into data processing engine architecture, how different components interact with each other and how data flows through a compute graph.
  • Learning and embracing the Apache development process. Within a month:
    • Profiling query runs for data engines and analyzing the execution telemetry to better understand how query engines works.
    • Diving deep into the various relational algebra algorithms to understand how they work and how they can be improved.
    • Working with the team on fixing bugs, implementing simple optimizations or code refactoring projects. In addition, Principal Engineers will be expected to:
      • Make small improvements to more sophisticated engine components such as resource management, task scheduling, and fault tolerance. Within 6 months:
        • Building new relational algebra components to expand SQL coverage or DataFrame functionality coverage.
        • Making small improvements to more sophisticated engine components such as resource management, task scheduling, and fault tolerance.
        • Helping systems improve by using more modular and composable components. In addition, Principal Engineers will be expected to:
          • Propose and implement core architecture improvements to engines components. Within 12 months:
            • Proposing and implementing core architecture improvements to engines components.
            • Working on challenging tasks such as language agnostic user defined functions, multi-query concurrency, and multi-tenancy.
            • Integrating engines with other components and features developed by other teams in the company to provide enterprise grade customer experiences. In addition, Principal Engineers will be expected to:
              • Lead core technical projects improving the engine architecture and performance. Previous experience that could be helpful:
                • Experience with data processing engines or frameworks.
                • Experience in distributed systems.
                • Working with SQL and non-SQL systems and their computational abstractions.
                • Developing in C++, especially using modern C++.
                • Developing for multiple types of hardware.
                  Additional Information:

                  The expected salary range is $165,000 to $220,000 + equity + benefits. Actual starting pay will be based on job-related factors, including exact work location, experience, training, and skill level, so may be higher or lower than what is shown on this posting.
