About The Role

What if your full-stack expertise could directly shape how AI writes and understands code for millions of developers around the world? We're looking for experienced Full Stack Engineers to evaluate AI-generated code, review system designs, and help train the next generation of AI models --- across the entire web stack.

This is a fully remote, flexible contract role built for senior engineers who want to do something meaningfully different with their skills. You'll work alongside world-leading AI research labs, applying your real-world engineering experience to make AI smarter, safer, and more technically rigorous.

Organization: Alignerr
Type: Hourly Contract
Location: Remote
Commitment: 10--40 hours/week

What You'll Do

Evaluate AI-generated code across the full stack --- frontend (React, Vue) and backend (Node, Python, C#) --- for correctness, efficiency, and best practices
Design and build full-stack tooling to support AI data annotation and quality control workflows
Review complex system architectures and provide detailed, actionable feedback on scalability and performance
Identify subtle bugs, edge cases, and architectural weaknesses in AI-produced code
Document your evaluations clearly and consistently using structured formats
Work independently and asynchronously --- on your own schedule

Who You Are

3--5+ years of professional full-stack engineering experience writing production-grade code
Proficient across the stack --- JavaScript/TypeScript, Python, and ideally Rust
Strong grasp of system design principles, performance trade-offs, and scalable architecture
Exceptionally clear written communicator --- you can explain complex technical decisions concisely
Master's or PhD in Computer Science or a related technical field from a reputable university
Self-directed and reliable when working independently without close supervision

Nice to Have

Experience with distributed systems, developer tooling, or AI/ML workflows
Familiarity with AI model evaluation or data annotation pipelines
Background in open-source development, technical writing, or code review at scale

Why Join Us

Work on cutting-edge AI projects alongside the world's leading research labs
Fully remote and flexible --- work when and where it suits you
Freelance autonomy with the structure of meaningful, technically rigorous work
Make a direct, tangible impact on how AI understands and generates code at scale
Potential for ongoing work and contract extension as new projects launch
