Staff Backend Engineer

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 focused on our data infrastructure, you won’t just write code—you’ll define core architecture and help scale a real-time telemetry platform from the ground up. You’ll work on complex backend systems designed to ingest, store, and serve millions of high-frequency data points per second, enabling faster iteration cycles for some of the most advanced engineering teams in the world.

In This Role, You'll :

Design and build a horizontally scalable platform for ingesting millions of hardware sensor data points per second

Develop durable, efficient database solutions to support real-time reads and large-scale analytics workloads

Pioneer data architecture by integrating recent innovations in streaming and storage, including cloud-native and diskless designs

Help define engineering culture, standards, and processes

Collaborate closely with peers on architecture, design, code reviews, and scaling strategies

The Skillset You'll Bring :

Bachelor's degree in Computer Science, Engineering, Physics, or another STEM discipline

7+ years of experience in backend, infrastructure, or data engineering roles

Hands-on experience with event-time-based stream processing or streaming SQL systems using tools like Apache Flink, Kafka Streams, Beam, or similar

Proficiency with relational and time-series databases like PostgreSQL, Druid, Pinot, TimescaleDB, or equivalent

Experience with large-scale distributed systems or low-latency backend services, ideally written in Go, Rust, or Python

Familiarity with DevOps and cloud infrastructure tools such as Kubernetes, Prometheus, ArgoCD, and Terraform

Strong communication skills and a collaborative approach to problem-solving

Bonus Points :

Familiarity with telemetry data from hardware systems, high-throughput ingest pipelines, or columnar storage formats like Apache Arrow and Parquet

Experience building resilient, performant systems that scale to billions of records

Curiosity about new data paradigms and eagerness to evaluate and integrate emerging tools and techniques

Engineering at Sift :

You’ll join a tight-knit team of world-class engineers building foundational systems for next-gen machines. Technologies you'll work with may include :

Frontend & Backend : Go, gRPC, PostgreSQL, Protobuf, React, TypeScript

Data Infrastructure : Apache Arrow, DataFusion, Flink, Kafka, Parquet, Rust

Ops & Tooling : AWS, Kubernetes, Docker, GitHub Actions, Prometheus, Argo CD, Grafana, Linux

Location :

Our team is based in El Segundo, CA , and works in person every Monday and Thursday . We’re open to relocating exceptional candidates or considering candidates who would stay located in the San Francisco, CA area.

Salary range : $200,000 - $250,000 per year. Plus equity and benefits.

Eligibility :

Due to the nature of our work, U.S. Citizenship or Green Card status is required to meet ITAR / EAR compliance requirements.
