[Apply for this position](#apply)[Email resume directly](mailto:careers@hanzo.ai?subject=Application%3A%20Senior%20Backend%20Engineer%20(Go%2FRust))

## About the Role

Our platform services handle millions of API requests daily: auth tokens, streaming completions, billing meters, webhooks, and agent fleet dispatch. You will build and scale our core microservices in Go and Rust.

Hanzo builds an open AI cloud — compilers, models, distributed infrastructure, and agent tooling. Our codebases are predominantly open source, and team members operate with high autonomy and end-to-end ownership.

## Key Responsibilities

Design, implement, and maintain high-throughput HTTP/gRPC backend microservices.

Scale our distributed datastores (PostgreSQL, ClickHouse, Redis, S3-compatible storage).

Build robust streaming pipelines for SSE completions, telemetry, and event buses.

Ensure high reliability, 99.99% uptime, zero-downtime deployments, and end-to-end security.

## What We're Looking For

Extensive experience building distributed systems in Go and/or Rust.

Solid knowledge of database internals, indexing, distributed transactions, and caching.

Experience with Kubernetes, Linux systems internals, network socket programming, and eBPF/monitoring.

High standards for code quality, automated testing, CI/CD, and post-incident reviews.

## Nice to Have

Experience building payment, subscription, or billing metering systems at scale.

Experience with message brokers (Kafka, NATS) and event-driven architectures.

## Why Join Hanzo

Remote-first cultureDistributed globally. We value outcomes over hours spent at a desk.

Public, open-source outputShip work that developers worldwide inspect, clone, and build on.

High agency & ownershipDirect access to leadership and the autonomy to build whole systems.
