Software Engineer, Full Stack

At Sift, we’re redefining how modern machines are built, tested, and operated. Our platform gives engineers real-time observability over high-frequency telemetry—eliminating bottlenecks and enabling faster, more reliable development.

Sift was born from our work at SpaceX on Dragon, Falcon, Starlink, and Starship—where scaling telemetry, debugging flight systems, and ensuring mission reliability demanded new infrastructure. Founded by a team from SpaceX, Google, and Palantir, Sift is built for mission‑critical systems where precision and scalability are non‑negotiable.

As an early engineer at Sift, you won’t just write code—you’ll help define the architecture, shape the product, and influence the culture of a company focused on solving real engineering problems. If you’re looking for complex technical challenges and the opportunity to build foundational systems supporting complex machines from the ground up, we want to hear from you.

In This Role, You'll :

• Build and maintain full stack features across our web application and data processing backend for complex telemetry data
• Create intuitive user interfaces for data exploration while optimizing for large real‑time datasets
• Implement efficient APIs and data access patterns for real‑time data streaming
• Collaborate with data platform and frontend teams on service design and implementation
• Write clean, maintainable code and participate in technical design discussions
