A technology company is looking for skilled full-stack web application developers (JavaScript/TypeScript + Python or Node) to join an innovative technology project.
- You will design, build, and maintain functional, robust, and user-friendly web applications.
- This opportunity is ideal for professionals with hands-on experience in modern frontend frameworks, backend APIs, databases, and shipping interactive web products end-to-end.
What you will do.
- Design, build, and refine browser-based applications with real logic, state, persistence, and user input.
- Work on standalone Python applications and data-processing scripts.
- 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 into product features.
- Handle state management, user input validation, error states, and loading states cleanly.
- Build standalone Python tools and scripts (data processing, API clients, lightweight backend utilities).
- Review, debug, optimize, and refactor full-stack applications.
- Write clear, testable code and debug end-to-end issues.
What they ask
- At least 3 years of relevant experience in full-stack web development or shipping interactive web applications.
- 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.
- Portfolio of shipped web applications.
- English proficiency: Upper-intermediate (B2) or above.
Profile
- Strong foundation in full-stack web development, modern frontend frameworks, backend architecture, and building interactive browser-based applications end-to-end.
- Ability to confidently work across frontend, backend, databases, and APIs.
- Ability to design robust application logic and build production-ready web applications.
- Strong problem-solving skills and attention to detail.
- Ability to independently architect and ship complete features.
