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:

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

The Skillset You'll Bring:

8+ years of professional experience in full-stack software development

Experience building production applications with technologies like React, NextJS, TypeScript, Go, Rust, and Python

Familiarity with relational and non-relational databases, e.g. PostgreSQL, Druid, Pinot, Timescale, or similar

Strong problem-solving skills and attention to detail

Bonus Points:

Experience with technical visualization tools (WebGL, D3.js, Apache ECharts) and time-series data

Knowledge of WebAssembly and browser-based computation

Background in scientific computing or technical data visualization

Experience building tools for technical users (dashboards, data-editing environments)

Built and launched side projects with consistent usage traffic
