ABOUT US

We are a US e-commerce company. We run the whole business on one internal web panel that we build ourselves: orders, customer support, call center, hiring, analytics, and ad production with AI video and image models. It is live and the team uses it every day.

THE ROLE

You will be the developer who owns this panel. The founder gives you the idea and a clear "done when". You plan it, build it with AI coding agents (Cursor), review what the agent wrote, test it, and ship it.

This is not a prompt-only job. The agent writes a lot of the code, but you are the one who reads the diff, finds the bug, and says no to a bad change.

STACK

• Next.js and TypeScript
• Supabase (PostgreSQL, SQL migrations)
• Vercel, Cloudflare R2
• A background job queue on a Linux VPS
• External AI APIs (video, image, LLM)
• GitHub with a protected main branch and pull requests

YOU ARE A GOOD FIT IF

• You have 3+ years of real web development with React or Next.js.
• You can write SQL and TypeScript by hand, without an AI tool.
• You use AI coding agents every day and you know where they fail.
• You can explain a technical problem in three simple sentences.
• You write clear English.
• You can work full-time for one company.

NOT A FIT

• Agencies and teams. We hire one person.
• People who can only prompt and cannot read the code.
• People with several other clients at the same time.

HIRING PROCESS

1. A 14-minute online test (code reading, multiple choice). We send you the link in chat right after you apply.
2. A 20-minute written test (a small function, one SQL query, three short answers).
3. A short live call with screen share.

We do not read CVs first. The test decides who moves on, and we reply to everyone who passes step 1.

Important: We expect AI tools to be part of your daily workflow. Candidates who primarily rely on traditional development approaches and do not actively use modern AI coding tools are unlikely to be a good fit for this role.

Are you an AI-driven Full Stack Engineer who uses modern AI tools to build faster, ship faster, and solve complex problems more efficiently?
 

At GT Protocol, we're not looking for traditional developers. We're building an AI-first engineering culture where AI is deeply integrated into the development workflow — from architecture and coding to testing, debugging, research, and product delivery.
 

We are looking for a Senior Full Stack Engineer who embraces AI-assisted development and understands how to leverage modern AI tools to maximize productivity and focus on solving real business problems rather than spending time on repetitive tasks.
 

About the Role

You will be working on GT Protocol's AI-powered trading and investment platform, helping build products used by thousands of users across Web3, CeFi, and DeFi ecosystems.
 

This role combines backend development, frontend development, AI integrations, trading infrastructure, blockchain analytics, real-time systems, and modern AI-driven engineering practices.
 

You will participate in designing and building scalable products while actively utilizing AI development tools as part of your daily workflow.
 

What We Expect from an AI-Driven Engineer

• Comfortable using AI coding assistants as a core part of the development process
• Experience working with tools such as Cursor, Claude Code, ChatGPT, Gemini, Copilot, Windsurf, or similar solutions
• Ability to effectively use AI for coding, architecture exploration, debugging, code reviews, documentation, testing, and research
• Strong focus on shipping results rather than maximizing manual coding hours
• Curiosity and willingness to continuously adapt to new AI-driven development workflows
• Understanding that AI is a productivity multiplier, not a replacement for engineering fundamentals
   

We believe the future belongs to engineers who can combine strong technical skills with the ability to leverage AI effectively. Our goal is to build a team that operates significantly faster than traditional software teams while maintaining high engineering standards.
 

Responsibilities and Duties

• Participate in the design, development, and maintenance of a sophisticated AI-powered trading platform serving thousands of users worldwide
• Develop and maintain backend services using Python, FastAPI, PostgreSQL, MongoDB, and Redis

• Integrate centralized and decentralized exchanges, blockchain networks, and third-party APIs
• Design and implement real-time systems using WebSockets, Socket.IO, asyncio, and event-driven architectures
• Develop AI-powered features, portfolio analytics, trading automation, and market intelligence tools
• Build and maintain Telegram-based products and AI assistants
• Collaborate closely with Product Managers, Designers, AI Engineers, and other Developers
• Participate in architectural decisions, code reviews, and continuous platform improvements
• Ensure high performance, scalability, and security across all platform components
   

Work Experience

• 4+ years of commercial software development experience
• Experience building production-grade web applications and APIs
• Experience working with cryptocurrency, trading, fintech, Web3, or blockchain products
• Experience working in distributed remote teams
• Bachelor's degree will be a plus
   

Required Skills

• Strong Python knowledge, FastAPI, asyncio, aiohttp, websockets, SQLAlchemy 2.x (async), PostgreSQL, MongoDB, Redis
• JavaScript, TypeScript, React 18+, Next.js, Redux / Redux-Saga, Tailwind CSS
