Java Full Stack

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

- Text module with selectable AI text models

- Image / Design generation via external AI APIs

- Video generation via external AI APIs

- 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.

We are looking for a Senior Full-Stack Developer / Tech Lead who can write code, structure the project technically, and help define the right staged development plan.

Responsibilities:

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

- Build or lead the core web application

- Implement frontend and backend logic

- Integrate external AI generation APIs

- Build user dashboard, admin panel, generation history and credits/coins logic

- Set up database, storage, deployment and basic monitoring

- Help structure AI provider integrations and dynamic pricing

- Help define Workflow / Space architecture

- Help define Telegram bot / Mini App integration approach

- Work with UI/UX designer, Telegram developer, workflow/frontend developer or other specialists if needed

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

We are not looking for a large agency. We prefer a strong individual developer or a compact team that can move fast, communicate clearly and build a practical commercial product in stages.

Why This Role Matters

We’re looking for a Principal Engineer to lead the architecture and execution of our GenAI-powered, self-serve marketing platforms. You will work directly with the CEO to shape, build, and scale products that change how marketers interact with data and AI. This is intrapreneurship in action — not a sandbox innovation lab, but a real-world product with traction, velocity, and high stakes.

What You'll Do

• Co-own product architecture and direction alongside the CEO.
• Build GenAI-native, full-stack platforms from MVP to scale — powered by LLMs, agents, and predictive AI.
• Own the full stack: React (frontend), Node.js/Python (backend), GCP (infra), BigQuery (data), and vector databases (AI).
• Lead a lean, high-caliber team with a hands-on, unblock-and-coach mindset.
• Drive rapid iteration with rigor, balancing short-term delivery with long-term resilience.
• Ensure scalability, observability, and fault tolerance in multi-tenant, cloud-native environments.
• Bridge business and tech — aligning execution with evolving user and market insights.

What You Bring

• 8–12 years of experience building and scaling full-stack, data-heavy or AI-driven products.
• Fluency in React, Node.js, and Google Cloud (Functions, BigQuery, Cloud SQL, Airflow, etc.).
• Hands-on experience with GenAI tools (LangChain, OpenAI APIs, LlamaIndex) is a bonus.
• Track record of shipping products from ambiguity to impact.
• Strong product mindset — your goal is user value, not just elegant code.
• Architectural leadership with ownership of engineering rigor and scaling best practices.
• Startup or founder DNA — you’ve built things from scratch and know how to move fast without breaking things.

Who You Are

• A former founder, senior IC, or tech lead who’s done zero-to-one and 1-to-n scaling.
• Hungry for ownership and velocity — frustrated by bureaucracy or stagnation.
• You code because you care about solving real problems for real users.
• You’re pragmatic, hands-on, and grounded in first principles.
• You understand that great software isn't just shipped — it's hardened, maintained, and evolves with minimal manual effort.
• You’re open to evolving into a founding engineer role with influence over the tech vision and culture.

What You Get

• Equity in a high-growth product-led startup.
• A chance to build global products out of India with full-stack and GenAI innovation.
• Access to high-context decision-making and direct collaboration with the CEO.
• A tight, ego-free team and a culture that values clarity, ownership, learning, and candor.

Why YOptima?

YOptima is redefining how leading marketers unlock growth through full-funnel, AI-powered media solutions. As part of our growth journey, this is your opportunity to own the growth charter for leading brands and agencies globally and shape the narrative of a next-generation marketing platform.
