Full Stack Engineer

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

• 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

• 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

• 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

• 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
