Founding Engineer for AI Community agent builder Platform

We’re an early-stage startup building an all-in-one community platform where people, AI agents and opportunities come together to create real income. We have the vision, the concept and the product design. Now we need the engineer who will turn it into a working platform.

The role
You will be our founding engineer, responsible for building the entire platform end-to-end: architecture, backend, frontend, AI agents, payments and infrastructure. You’ll have full technical ownership and work directly with the founder. If the platform is built well, this role can grow into a long-term partnership.

What you’ll build

Platform and community

User accounts, profiles, onboarding and authentication
Community features: spaces/channels, projects, events, a learning hub and messaging
A marketplace for agents, services and digital products
A responsive web app (with a mobile app later on)

AI agents

Autonomous AI agents that do revenue-generating work (e-commerce, content creation, design, web building and more)
An agent framework where users can use, build and publish their own agents
Infrastructure for running, monitoring, rating and tracking agents, including cost and earnings per agent

Investment and revenue-share system

Users can put money into agent budgets or projects and own a percentage share
Returns are distributed automatically based on each user’s share, much like owning stocks
A ledger that accurately tracks contributions, ownership, earnings and payouts
Dashboards showing performance, portfolio value and returns

Wallet and platform currency

An in-app wallet for deposits, withdrawals and payouts (e.g. Stripe or Stripe Connect)
A native platform currency used for rewards, the marketplace and premium features
Groundwork for a future payment card integration

Security and infrastructure

Scalable cloud architecture, CI/CD, monitoring and backups
KYC/AML hooks, fraud prevention, GDPR compliance and full audit logs

What we’re looking for

5+ years of full-stack development, including having built and launched at least one complete product from scratch
Hands-on experience building LLM-based apps and AI agents (OpenAI, Anthropic, open-source models, LangGraph, CrewAI or your own orchestration)
Strong backend skills (Python and/or Node.js/TypeScript, PostgreSQL)
Strong frontend skills (React or [login to view URL], Tailwind) and the ability to implement a polished, modern UI
Experience with payments, fintech or systems where money must be handled accurately
Cloud and DevOps experience (AWS, GCP, Vercel, Supabase or similar)
An independent, product-minded builder who makes good technical decisions and ships fast

Nice to have

Experience with investment, crowdfunding or revenue-share platforms
Knowledge of EU/Swedish financial regulation, or experience working with compliance teams
Experience building community platforms or marketplaces
Mobile development (React Native or Flutter)

What we offer

Full technical ownership: you build the platform from day one
A path to partnership: if the platform is built well and we work well together, I’m open to bringing you on as a long-term partner or co-founder later, with equity and a CTO role
Remote-first and flexible

How to apply
Send the following:

Your CV or LinkedIn profile
Your GitHub or portfolio, including at least one product you built end-to-end
A short description of how you would structure a platform like this: tech stack, architecture and what you would build first
