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

- 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

- 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.

Tech Lead (India) — Help Build WebLager’s Next Engineering Hub
Location: India
Team: Product & Development
Reporting to: Head of Product & Development (Denmark)
Why this role exists
WebLager is scaling fast, and 2026 will be a breakout year. We’re building an Indian IT office that’s not an outsourced extension of Denmark.
This is a real “build it right from day one” leadership role.
You’ll be our right hand in India — shaping the team, culture, and delivery. If you want to build something meaningful that’s expected to grow a lot next year, keep reading.
What you’ll do
You’re not here to babysit Jira. You’re here to ship, lead, and raise the bar.
● Build and lead our India engineering team from early stage into real scale in 2026.
● Set standards for quality and delivery — clean code, stable systems, smart execution.
● Coach and grow people across levels: students, juniors, mid-levels, seniors.
● Create a local WebLager community that feels like one company, not two offices.
● Work tightly with Denmark on product, architecture, and delivery — as a partner, not a follower.
● Stay hands-on: design, code, review, refactor, deploy.
● Scale enterprise systems: performance, reliability, maintainability, observability.
● Improve how we work: CI/CD, engineering rituals, docs that matter, fewer surprises.
● Be the technical anchor when things are complex, messy, or moving fast.
What you bring
We don’t care about buzzwords. We care about proof you can build and lead.
Must-haves:
● 5+ years as a developer, with real production systems behind you.
● Strong backend skills — ideally Python or another scripting language, plus Java/C# or similar, and also extensive database knowledge of both relational and
non-relational databases.
● Frontend experience with a reactive framework like Angular, React, Vue, etc.
● Experience scaling enterprise-grade systems and making architecture tradeoffs that hold up.
● You’ve led people before (formally or naturally) and enjoy helping others grow.
● Excellent problem-solving skills — you don’t freeze when things are unclear; you untangle them.
● Near-perfect English (spoken and written). This is non-negotiable — you’ll work daily across countries and levels.
● You take ownership by default and don’t need a map for every step.
Nice-to-haves:
● You’ve helped build or grow a team from scratch.
● Cloud + DevOps experience.
● Product-minded engineering: you care about outcomes, not just tasks.
The kind of person who’ll thrive here
Let’s be direct:
● You’re driven to create real results, not just “do your part.”
● You want to build something from the ground up and shape the future of a company.
● You lead with calm, clarity, and high standards.
● You’re motivated beyond the norm — you don’t settle for “good enough.”
● You know a Tech Lead is someone who steps up, helps others win, and keeps shipping.
● You’re hungry to learn, and confident enough to challenge weak solutions.
The kind of person who won’t
Also direct:
● If you expect everything to be built around you, look for another job.
● If you want Denmark to hand you tasks, this isn’t it.
● If you avoid responsibility or hard conversations, this will hurt.
● If “average and comfortable” is your goal, don’t apply.
We’re building an exceptional team. Mediocre doesn’t survive here.
What you get
● A rare chance to build an office, a culture, and a high-performing team in India from scratch.
● Direct partnership with Danish leadership and product org.
● Real influence over architecture, standards, and execution.
● A company that values ownership and speed over politics.
● Massive growth opportunity as the India office scales in 2026.
● Competitive salary + benefits.
How to apply
Only reach out if you genuinely believe you’re the right fit and you’re motivated to build something one-of-a-kind.
Send: (This is mandatory)
● A short page about you and what you’ve built.
● CV/LinkedIn/GitHub/portfolio.
● 2–3 projects you’re proud of, and why.
