Sr Java Developer

We are building VYXN.AI — a full AI content generation platform with a web application, Templates, Workflow / Space, dynamic credits/coins pricing, AI provider integrations, Telegram bot and Telegram Mini App.

The final goal is not a small prototype. The product should be built in clear stages:

1. Technical Foundation

2. First usable product release

3. Full commercial launch scope

The first stage should focus on building a stable technical base, not an over-engineered enterprise system.

Core product areas:

- Web AI content generation platform

- Templates section with visual examples, prompts and user photo upload

- Dynamic credits / coins pricing based on provider, model, quality, duration and generation parameters

- Generation history

- User dashboard

- Admin panel

- AI provider integration layer

- Basic working version of Workflow / Space with node-based UI

- Telegram bot

- Telegram Mini App

- Customer support bot

- Multilingual support

Important:

The platform should be built using existing AI APIs and providers, not by training custom AI models at the first stage.

Responsibilities:

- Review the full project brief and propose a practical implementation plan

- Build or lead the core web application

Required skills:

- React.js / Next.js

- TypeScript

- Node.js

- PostgreSQL

- API integrations

- SaaS or web platform experience

- Backend architecture understanding

- Ability to work independently and communicate clearly

- Comfortable with fixed milestones and clear acceptance criteria

Nice to have:

- Redis / BullMQ / queues

- AI API integrations

- Image or video generation API experience

- React Flow or node-based workflow UI experience

- AWS / GCP / Cloudflare / S3-compatible storage

- Telegram Bot / Telegram Mini App experience

- Dynamic pricing, wallet, credits or usage-based billing experience

- Admin panels and support tools

Project format:

- Remote

- Contract or full-time possible

- Fixed milestones preferred for the first stages

- Code must be developed in our GitHub repository

- Deployment should be done through project-owned accounts

- Long-term cooperation possible if the first stage goes well
