About Sift
Sift is the data infrastructure platform for hardware engineering teams. Sift turns high-frequency telemetry into engineering insights for mission-critical systems. Teams use Sift to build and operate rockets, satellites, autonomous vehicles, energy systems, defense platforms, and more.
Founded by former SpaceX engineers who built the tools behind Dragon and Starlink, Sift is building the data infrastructure to herald the AI era for physical systems.
In This Role, You'll:
Design and optimize data pipelines that run entirely in the browser: Web Workers processing Apache Arrow binary data, persistent caching in the Origin Private File System, and multi-layer invalidation strategies that keep the UI responsive while handling datasets that would crash most web apps.
Build interactive visualizations for time-series telemetry, FFT frequency analysis, geographic mapping, and scatter plots, and many more, each with distinct performance profiles and correctness constraints. When your users are debugging flight hardware, a rendering inaccuracy is a mission-critical problem, not a cosmetic one.
Solve performance problems that frameworks can't: bypassing React's render cycle for 60fps interactions, coordinatin
