Job description

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 high-performance data visualization interfaces and reusable component libraries for complex telemetry data
• Create intuitive user interfaces for data exploration while optimizing for large real-time datasets
• Collaborate with backend teams on API design and implementation for seamless user experiences
• Write clean, maintainable code and participate in technical design discussions

The Skillset You'll Bring:

• 5+ years of professional experience building web applications and data-driven tools
• Strong experience building production applications with technologies like React, NextJS, and TypeScript
• Experience with modern CSS (Tailwind) and component libraries (Radix UI) for building design systems

Bonus Points:

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

You’ll have the opportunity to help evolve and scale our platform because we’re still in the early stages of building the product. Relevant technologies include:

Web frontend & backend: React, TypeScript, Redux, Tailwind, WebAssembly, D3.js, WebGL, and Go

Data: Parquet, Flink, Kafka, Redpanda, Beam, DuckDB, Timescale, QuestDB, InfluxDB, and Druid

Location:

Sift’s headquarters is in Marina Del Rey, CA (Next to LAX). We collaborate in person twice a week—on Mondays and Thursdays—and come together for a full week every two months. We are open to relocating candidates to LA or working from our San Francisco office for the right candidate.

Salary range: $180,000 - $230,000 per year. Plus equity and benefits.
