[Hiring] Freelance Full-Stack Web App Developer @Mindrift

Role Description

Mindrift is looking for skilled Full-Stack Web App Developers (JavaScript/TypeScript + Python or Node) to join the Tendem project (https://tendem.ai/) and build interactive browser-based applications within our hybrid AI + human environment. In this role, as an AI Pilot – that's how we refer to this position at Mindrift – you'll collaborate with Tendem Agents that handle repetitive tasks, while you provide full-stack engineering expertise, architectural judgment, and quality control to ensure web apps are functional, robust, and ready for real users. This part-time remote opportunity is ideal for professionals with hands-on experience in modern frontend frameworks, backend APIs, databases, and shipping interactive web products end-to-end.

Key Responsibilities

• Build interactive web applications with frontend (React, Next.js, Vue, or similar) and a backend API (Python/FastAPI/Flask or Node/Express).
• Design and implement data models, schemas, and persistence layers using SQL (PostgreSQL, SQLite) or NoSQL stores.
• Implement authentication, sessions, and basic role-based access where needed.
• Integrate third-party APIs and AI/LLM services (OpenAI, Anthropic, or similar) into product features.
• Handle state management, user input validation, error states, and loading states cleanly.
• Build standalone Python tools and scripts where required by the task (data processing, API clients, lightweight backend utilities).
• Evaluate AI-generated full-stack code and refactor it for correctness, security, performance, and maintainability.
• Write clear, testable code and debug end-to-end issues across frontend, backend, and database.

Qualifications

• At least 3 years of relevant experience in full-stack web development or shipping interactive web applications (required).
• Bachelor's or Master's Degree in Computer Science, Engineering, Information Technology, or related technical fields is a plus.
• Strong foundation in full-stack web development, modern frontend frameworks, backend architecture, and building interactive browser-based applications end-to-end.
• Strong command of JavaScript/TypeScript and at least one modern frontend framework (React, Next.js, Vue, Svelte, or similar).
• Solid backend experience in Python (FastAPI, Flask, Django) and/or Node.js (Express, NestJS).
• Hands-on experience with relational databases (PostgreSQL, MySQL, SQLite) and basic schema design.
• Experience implementing REST APIs, request validation, error handling, and authentication flows.
• Familiarity with deployment platforms (Vercel, Netlify, Render, Fly.io, Railway, or similar).
• Experience integrating LLM APIs or other AI services into product features is a strong plus.
• Comfortable with version control (Git) and basic testing practices.
• Strong attention to detail and commitment to building working, robust products — not demos.
• Self-directed work ethic with the ability to architect, build, and ship features independently.
• Portfolio of shipped web applications (required).
• English proficiency: Upper-intermediate (B2) or above (required).

Requirements

• Project tasks are estimated to require around 10–20 hours per week during active phases, based on project requirements.

Compensation

• Contributors can earn up to $60 per hour equivalent, depending on their level and pace of contribution.
• Compensation varies across projects depending on scope, complexity, and required expertise.

Benefits

• Work fully remote on your own schedule with just a laptop and stable internet connection.
• Gain hands-on experience in a unique hybrid environment where human expertise and AI agents collaborate seamlessly.
• Participate in performance-based bonus programs that reward high-quality work and consistent delivery.
