The Role
As a Senior Software Engineer at Sift, you will develop high-performance data visualization interfaces using technologies like React and TypeScript, collaborating with backend teams and optimizing for real-time datasets.
Summary Generated by Built In

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:

  • 5+ 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

  • Infrastructure: GitHub Actions, AWS, Azure, GCP, Docker, Kubernetes, and Terraform


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: $170,000 - $220,000 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.

What We Do

Sift is transforming how modern machines are built and operated. Our platform goes beyond traditional monitoring, enabling automated data review that catches unusual conditions in systems too complex for manual checks. This not only enhances reliability but also dramatically speeds up development cycles.

At our core, we provide a unified solution for ingesting, storing, and analyzing vast amounts of machine data. By combining powerful data processing with easy-to-use visualizations, we help engineers make sense of enormous amounts of information. From spacecraft to self-driving cars, Sift is the backbone of innovation for companies pushing technology to new limits.

Born from the challenges of spaceflight, Sift aims to accelerate technological progress. We believe that by giving engineers better tools to understand and improve their creations, we can unlock a new era of innovation. Our mission goes beyond solving today's engineering problems; we're building the foundation for a future where the most ambitious machines are developed with confidence, run with precision, and constantly improved.

We're also tackling related challenges like simplifying regulatory compliance, and improving manufacturing processes. By connecting data from various sources—from sensors to manufacturing records to regulatory requirements—we're empowering a new generation of engineers to build the technologies that will shape our world.

Join us in our journey to usher in this new age of reliable, groundbreaking technology. Whether you're launching rockets, developing autonomous systems, or advancing energy and transportation, Sift is your partner in turning vast amounts of data into insights that drive innovation forward.
