Software Engineer, Frontend

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 Space

X on Dragon, Falcon, Starlink, and Starship—where scaling telemetry, debugging flight systems, and ensuring mission reliability demanded new infrastructure. Founded by a team from Space

X, 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.

• 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

• 3+ years of professional experience building web applications and data-driven tools

• Strong experience building production applications with technologies like React, NextJS, and Type Script

• Strong understanding of web performance optimization and browser rendering

• Experience with modern CSS (Tailwind) and component libraries (Radix UI) for building design systems

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

• Knowledge of Web Assembly 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

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, Type Script, Redux, Tailwind, Web Assembly, D3.js, WebGL, and Go

• Data
  :
  Parquet, Flink, Kafka, Redpanda, Beam, DuckDB, Timescale, Quest
  
  DB, Influx
  
  DB, and Druid

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

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.
