Join to apply for the Software Engineer, Full Stack 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 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

• 3+ 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
  
  

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: ECharts, Go, gRPC, PostgreSQL, Protobuf, Radix, React, Redux, and TypeScript
• Data: Arrow, DataFusion, Flink, Parquet, and Rust
• Infrastructure: Argo CD, AWS, Docker, GitHub Actions, Grafana, Kubernetes, Kustomize, Linux, Prometheus, and Terragrunt
  
  

Location:

The Sift team is based in El Segundo. We collaborate in person two times per week, Monday and Thursday. We work closely with hardware companies, many of which are based in LA, building everything from autonomous vehicles to spacecraft. As a customer-centric company, being nearby for site visits and collaboration is essential. Sift is open to relocating you to LA.

Salary range: $150,000 - $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.
