Join to apply for the Software Engineer, Frontend role at Sift

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 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

3+ years of professional experience building web applications and data-driven tools
Strong experience building production applications with technologies like React, NextJS, and TypeScript
Strong understanding of web performance optimization and browser rendering
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
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

Engineering At Sift
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 El Segundo, CA . We collaborate in person twice a week—on Mondays and Thursdays —and come together for a full week every two months. While we prefer team members to be local, we’re open to relocating candidates to LA or considering remote work from the San Francisco area for the right candidate.
Salary range: $160,000 - $200,000 per year. Plus equity and benefits.
Eligibility
US Person Required : Must be a U.S. Citizen or Green Card Holder due to ITAR (International Traffic in Arms Regulations) / EAR (Export Administration Regulations) compliance requirements.
