The position is a blend of software engineering and systems engineering, with a strong focus on building and evolving control and data planes, improving underlying systems, and writing software that implements critical workflows to automate and enhance the operation of our large-scale storage infrastructure.

We also work with our product teams to make the underlying Storage technologies work better for Reddit’s main workloads, including defining and improving the application’s data models and data access patterns, and lots of times, this also involves data-driven analysis and tuning of the Storage stack to make step function improvements to the end-to-end data path. There is a substantial amount of troubleshooting and analysis to understand the real problems we face as we scale, and our customer’s workloads change.

A successful candidate will;

• Design, write, and deliver software to improve the availability, scalability, latency, and efficiency of Reddit’s products in Go, C++ and sometimes Python.
• Dive deep into the codebase of supported storage systems to understand system internals.
• Be able to make system level improvements, enhancements and implement complex code modifications.
• Engage actively with the open-source community to implement and upstream changes to the OSS codebase.
• Contribute to the design and implementation of high-performance, large-scale distributed storage systems to power various use cases at Reddit.
• Collaborate closely with engineering teams and stakeholders to integrate storage capabilities into broader storage infrastructure and use cases across Reddit.
• Mentor and guide other engineers on how to design, build and evangelize vector storage services across Reddit

Who You Might Be:
