Front-End Software Engineer

About Us

At Union, we are solving one of the hardest challenges in AI infrastructure today: enabling high-velocity iteration while maintaining seamless production-readiness for AI workloads at scale. Flyte, the open-source project we steward, is the emerging standard for modern data and AI orchestration, with numerous leading technology organizations - like LinkedIn, Spotify, and Gojek - running millions of mission-critical workloads on the platform. We have a deep bench of infrastructure veterans from companies in the Big Three and beyond and a technical founding team who originally created Flyte while at Lyft.

• You have experience with NodeJS (and optionally protobufjs) for server-side development and API integration.
• You have a strong foundation in data structures and algorithms, with a focus on profiling and performance optimization.
• You will be expected to be in-office.
