Full Stack Engineer

Alignerr is seeking experienced Full Stack Engineers to evaluate AI-generated code and help train the next generation of AI models. This role involves reviewing system designs and building tooling to support AI data annotation and quality control workflows.

Responsibilities:

• 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

Requirements:

• 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
