About the company

About the role

We're looking for a software engineer who loves to build high performance data processing systems. Our customers are scaled up companies who send complex, semi-structured data which they need to process and analyze in real-time. Our unique architecture allows them to store this data on-prem, while creating complex visualizations that load instantly. Check out our Brainstore blog post.

You will play a significant role in the foundational system architecture, technology choices, and implementation. Our founding team has deep expertise in database and ML systems, and you'll be empowered to both collaborate closely with them and explore your own ideas.
