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, build, and operate backend systems that process and store large volumes of real-time telemetry data.

• Own features end-to-end, from design to post-launch improvement.

• Collaborate with Frontend, Design, and Data teams to ensure features solve real customer problems.

• Optimize backend systems for performance, scalability, and reliability.

• Contribute to system evolution—migrating services, introducing caches, and improving storage or indexing layers.

• Participate in on-call rotations, debugging live issues, and improving observability.

• Raise the bar through code reviews, shared patterns, and men
