Data Infrastructure Engineer (Rust) - High Performance Computing
Role summary
Alignerr is seeking a Senior Rust Engineer for a fully remote, flexible contract role. The engineer will design, build, and optimize high-performance Rust systems for AI data pipelines and evaluation workflows. Responsibilities include developing tooling for data annotation, validation, and quality control, identifying and fixing performance bottlenecks through profiling and SIMD optimizations, and improving system reliability. The role requires 5+ years of production-grade Rust experience, deep expertise in data parallelism, concurrency, memory layout, and SIMD. Familiarity with AI/ML workflows, distributed systems, and developer tooling is a plus. This is an opportunity to work on cutting-edge AI infrastructure with leading research labs.
Data Infrastructure Engineer (Rust) — High Performance Computing
About The Role
What if your mastery of Rust could directly shape the infrastructure powering the next generation of AI? We're looking for a Senior Rust Engineer to build the high-performance data pipelines, annotation tooling, and evaluation systems that leading AI labs depend on to train and improve their most advanced models.
This is a fully remote, flexible contract role for an elite systems engineer who knows Rust at a deep level — memory layout, SIMD, concurrency, and all. You'll work on real production systems at the frontier of AI development, collaborating with research and engineering teams doing genuinely important work.
- Organization: Alignerr
- Type: Hourly Contract
- Location: Remote
- Commitment: 20–40 hours/week
What You'll Do
- Design, build, and optimize high-performance Rust systems supporting large-scale AI data pipelines and evaluation workflows
- Develop full-stack tooling and backend services for data annotation, validation, and quality control
- Identify and eliminate bottlenecks through deep profiling, SIMD optimizations, and careful memory management
- Improve reliability, performance, and safety across existing Rust codebases
- Collaborate with data, research, and engineering teams to support model training and evaluation workflows
- Participate in synchronous design reviews and iterate quickly on system architecture decisions
Who You Are
- 5+ years of professional experience writing production-grade Rust
- Deep expertise in data parallelism and concurrency patterns — you know how to maximize CPU saturation
- Strong command of memory layout, SIMD optimizations, and heap allocation strategies to hunt down and fix performance bottlenecks
- Native or fluent English speaker with clear written and verbal communication skills
- Able to commit 20–40 hours per week consistently
- Self-directed and comfortable working asynchronously in a remote engineering environment
Nice to Have
- Prior experience with data annotation pipelines, data quality systems, or evaluation infrastructure
- Familiarity with AI/ML workflows, model training, or benchmarking pipelines
- Experience with distributed systems architecture or developer tooling
- Background working with or alongside AI research teams
Why Join Us
- Work on cutting-edge AI infrastructure projects alongside leading research labs
- Fully remote and flexible — structure your work around your life
- Freelance autonomy with the substance of high-impact, senior-level engineering work
- Tackle genuinely hard systems problems that matter at scale
- Potential for ongoing work and contract extension as new projects launch
