Alignerr Corp.; Seattle (WA); Remote; USD 55,000 - 165,000; Part time

Job summary

Alignerr is seeking an experienced Full Stack Developer to help shape how AI writes, evaluates, and reasons about code for millions of developers worldwide. This is a fully remote, hourly contract role built for engineers who want meaningful, high‑impact work on their own schedule.

You will review AI‑generated code from frontend to backend (React, Vue, Node.js, Python, Rust), identify issues, design full‑stack tooling, and provide clear feedback to improve AI model outputs while working

Qualifications

• 3–5+ years of professional full-stack development experience shipping production-grade code.
• Strong proficiency across JavaScript/TypeScript, Python, and Rust.
• Comfortable working across both frontend and backend layers without hand-holding.
• Sharp eye for code quality, system design, and engineering best practices.
• Excellent written communicator — you can explain complex technical decisions clearly and precisely.
• Master's or PhD in Computer Science or a related technical field from a reputable institution.

Responsibilities

• Evaluate AI-generated code across the full stack — from frontend interfaces (React, Vue) to backend logic (Node.js, Python, Rust).
• Identify bugs, architectural weaknesses, and performance bottlenecks in AI-produced code and designs.
• Design and build full-stack tooling to support AI data annotation and quality control workflows.
• Review complex system architectures and provide expert feedback on scalability, reliability, and efficiency.
• Write clear, structured technical feedback that helps improve AI model outputs.
• Work independently and asynchronously — fully on your own schedule.
