Jobs Fullstack

About Us

Unbreakable Network Media is building the next generation of SaaS products

and automations at the intersection of modern web development and applied AI.

We're not just building tools—we're building a company culture around shipping

fast, thinking like builders, and using AI as a force multiplier for

productivity, not just a gadget.

The Opportunity

You'll be the technical leader building our SaaS ecosystem from the ground up.

This means owning the entire tech stack, from frontend to backend to

infrastructure, and shipping products that matter.

Your Core Responsibilities

🚀 Full-Stack Web Development

Build end-to-end SaaS web applications with Next.js, React, TypeScript on

frontend and Python, Supabase on backend. Deploy and optimize on DigitalOcean

and Google Cloud. Design databases, REST APIs, and cloud infrastructure with

confidence.

🤖 AI-First Development

Use Claude, ChatGPT, Cursor, and Antigravity as core development tools—not as

gadgets, but as force multipliers. Build AI-powered features into products.

Leverage AI for rapid prototyping, debugging, and shipping velocity.

⚡ Rapid Prototyping & Production

Prototype quickly with Lovable (no-code/low-code for MVP velocity). Take

prototypes to production-grade SaaS. Ship MVPs in weeks, not months. Iterate

based on user feedback at speed.

🔧 Integrations & Automations

Build Telegram bots and custom integrations. Work with Google Ads API and

advertising platforms. Create marketing automation pipelines. Connect internal

systems with external services (Zapier, Make, etc.). Manage API integrations

at scale.

🏗️ Technical Leadership

Own the entire tech stack and architecture decisions. Define best practices

and development standards. Mentor and coordinate with other developers as the

team grows. Make autonomy-focused, builder-oriented decisions.

Tech Stack You'll Work With

Frontend: Next.js, React, TypeScript, Vite, TailwindCSS, shadcn/ui

Backend: Python (FastAPI/Flask), Supabase, PostgreSQL

Infrastructure: DigitalOcean, Google Cloud, Docker, GitHub Actions

AI Tools: Claude, ChatGPT, Cursor, Antigravity, Lovable

Integrations: Google Ads API, Telegram Bot API, Zapier/Make, webhooks

Join us to shape the future of autonomous AI agents for developers. You'll work closely with AI engineers and researchers to evaluate and improve AI-generated code — helping build systems that genuinely understand and accelerate software development.

The role

You will be one of the first engineering hire into the product team, reporting to our existing backend consultant and working directly with the founder.
