Alignerr is looking for a Senior Rust Engineer to build and optimize high-performance data pipelines and evaluation systems for AI research labs. The role involves designing and developing full-stack tooling and backend services, while collaborating with data and engineering teams to enhance model training workflows.
Responsibilities:
- Design, build, and optimize high-performance systems in Rust supporting AI data pipelines and evaluation workflows
- Develop full-stack tooling and backend services for large-scale data annotation, validation, and quality control
- Improve reliability, performance, and 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, and implement scalable fixes
- Participate in synchronous design reviews to iterate on system architecture and implementation decisions
Requirements:
- Native or fluent English speaker with clear written and verbal communication skills
- 5+ years of professional experience writing production-grade Rust
- Deep expertise in data parallelism and concurrency patterns to maximize CPU saturation
- Strong command of memory layout, SIMD optimizations, and heap allocation minimization to identify and resolve performance bottlenecks
- Self-directed and dependable — able to commit 20–40 hours per week and deliver without hand-holding
- Prior experience with data annotation, data quality pipelines, or evaluation systems
- Familiarity with AI/ML workflows, model training, or benchmarking pipelines
- Experience building distributed systems or developer tooling at scale
