Job summary

Eos Talent is seeking a Rust Engineer to join a widely used AI infrastructure company. You will lead the full migration of the core platform from Python to Rust, planned directly with the CTO, and own it end to end from architecture through rollout.

Not a feature engineering role. A performance bet. Every decision you make moves the platform toward lower latency and higher throughput at massive scale, without compromising the reliability enterprise customers depend on.

Qualifications

• Deep, long-standing Rust expertise with years of production experience.
• Strong focus on latency and throughput at massive scale.
• Balance ambitious change with reliability in live, high-volume systems.
• Bonus if you've led a Rust migration or shipped performance-critical systems.

Job description

Rust Engineer at a widely used AI infrastructure company. Single-owner mandate: you will lead the full migration of the core platform from Python to Rust, planned directly with the CTO, and own it end to end from architecture through rollout.

Not a feature engineering role. A performance bet. Every decision you make moves the platform toward lower latency and higher throughput at massive scale, without compromising the reliability enterprise customers depend on.

Needed:

• Deep, long-standing Rust expertise, you've been writing production Rust for years and know it cold
• Obsessive about latency and throughput at a level most engineers don't operate at
• Strong instinct for stability: you balance ambitious change against reliability in live, high-volume systems
• Major bonus if you've led a codebase migration to Rust before or have a track record shipping performance-critical systems.

Onsite in San Francisco or remote US/Canada.
