## About the Role

* Deep, long-standing expertise in Rust. You've been writing production Rust for years and know it cold.
 * Obsessive about performance. You care about latency and throughput at a level most engineers don't.
 * Strong instinct for stability, with a track record of balancing ambitious change against reliability.
 * Major bonus: prior experience leading codebase migrations from another language to Rust.
 * Major bonus: a demonstrated history of shipping performance-critical systems.
 * Familiarity with backend infrastructure, databases (PostgreSQL, Redis), and high-volume production systems., Adobe Product Family, Application Programming Interface (API), Artificial Intelligence (AI), Cross-Functional, Energy Efficiency, Leadership, PostgreSQL, Production Systems, Production Volume, Proxy Server, Python Programming/Scripting Language, Redis, Risk Management, Software Engineering, System Migration

## Description

You'll own LiteLLM's migration to Rust end to end. This is a high-stakes, high-visibility role: you'll plan the migration directly with the CTO, structure the codebase so it's ready for Rust, and lead a gradual, stability-first rollout. The work is fundamentally about performance. Every decision you make will move us toward being the lowest-latency, highest-throughput gateway in the category, without ever compromising the reliability our enterprise customers depend on.

This is a single-owner mandate. You will be the person leading the entire Python-to-Rust migration.

Responsibilities

 * Own the end-to-end migration of LiteLLM from Python to Rust, from architecture through rollout.
 * Plan the migration alongside the CTO, sequencing work to minimize risk to live, high-volume traffic.
 * Design and execute a gradual rollout that holds stability as the top constraint while the migration progresses.
 * Restructure the existing codebase so it's positioned for a clean, incremental move to Rust.
 * Drive performance gains across latency, throughput, and resource efficiency at 1B+ requests/mo.
 * Collaborate cross-functionally to ensure the migration aligns with backend priorities across performance, reliability, and security.
