Job summary

Sift is seeking an experienced backend/infrastructure engineer to design, build, and operate high-throughput telemetry systems. You will own features end-to-end, collaborate with frontend, design, and data teams, and optimize for performance, scalability, and reliability.

You will contribute to system evolution, participate in on-call rotations, and mentor teammates. A strong foundation in distributed systems and hands-on work with Go/Rust/Python, SQL, and Kubernetes is essential.

Qualifications

• Bachelor's degree in Computer Science, Engineering, Physics, or another STEM discipline.
• 7+ years of experience in backend or infrastructure roles.
• Strong understanding of distributed systems fundamentals—state, fault tolerance, recovery.
• Experience with Go, Rust, or Python, and strong Linux/networking fundamentals.
• Deep knowledge of SQL and operational database experience (indexing, migrations, tuning).
• Experience building and scaling APIs (REST, gRPC/Protobuf).
• Strong debugging skills and a production-first mindset.
• Familiarity with Kubernetes, Prometheus, Argo CD, and other modern infrastructure tools.

Responsibilities

• Design, build, and operate backend systems that process and store large volumes of real-time telemetry data.
• Own features end-to-end, from design to post-launch improvement.
• Collaborate with Frontend, Design, and Data teams to ensure features solve real customer problems.
• Optimize backend systems for performance, scalability, and reliability.
• Contribute to system evolution—migrating services, introducing caches, and improving storage or indexing layers.
• Participate in on-call rotations, debugging live issues, and improving observability.
• Raise the bar through code reviews, shared patterns, and mentorship.
