Rust Software Engineer - Distributed Systems
Senior Rust Engineer — AI Data & Distributed Infrastructure
About the Role
What if your Rust expertise could directly shape the infrastructure powering the next generation of AI? We're looking for a seasoned Rust engineer to build and optimize the high-performance distributed systems that leading AI labs depend on—from data pipelines and annotation tooling to evaluation infrastructure at scale.
This is a fully remote, flexible contract role for engineers who write production Rust, think deeply about distributed systems, and want their work to matter.
Organization: Alignerr Type: Hourly Contract Location: Remote Commitment: 20-40 hours/week
Responsibilities
- Design, build, and optimize high-performance Rust systems that support AI data pipelines and evaluation workflows
- Develop full-stack backend services and tooling for large-scale data annotation, validation, and quality control
- Improve reliability, safety, and performance across existing production Rust codebases
- Collaborate with data, research, and engineering teams to support model training and evaluation workflows
- Identify and resolve bottlenecks, edge cases, and systemic issues in distributed data systems
- Participate in synchronous design reviews and iterate on architecture and implementation decisions
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
