Senior Rust Engineer — AI Data & Infrastructure

Alignerr is seeking a Senior Rust Engineer to build and optimize high-performance data pipelines and evaluation systems for advanced AI models. The role involves collaborating with research and engineering teams to enhance model training and evaluation workflows while ensuring reliability and performance in Rust codebases.

Responsibilities:

• Design, build, and optimize high-performance systems in Rust that power AI data pipelines and evaluation workflows
• Develop backend services and tooling for large-scale data annotation, validation, and quality control
• Improve reliability, performance, and memory safety across existing Rust codebases
• Collaborate with data, research, and engineering teams to support model training and evaluation workflows
• Identify bottlenecks and edge cases in data and system behavior — then implement scalable, production-ready fixes
• Participate in synchronous design reviews to iterate on architecture and implementation decisions

Requirements:

• 5+ years of professional experience writing production-grade Rust
• Strong systems programming foundation — you think carefully about performance, concurrency, and memory safety
• Proven experience building backend services, developer tooling, or data pipelines
• Clear, direct communicator — written and verbal — comfortable working across technical and research teams
• Able to commit 20–40 hours per week with consistency and reliability
• Prior experience with data annotation systems, data quality pipelines, or model evaluation infrastructure
• Familiarity with AI/ML workflows, model training, or benchmarking pipelines
• Experience with distributed systems design or developer tooling at scale
• Exposure to Go, Python, or C++ in a systems context
