Senior Full Stack Engineer

Were a 9-person startup (4 founders 5 team members) building the first AI-powered humanless event agency. We have 40 AI agents in production 30 reusable UI components real-time streaming interfaces and real paying customers. We need a senior full stack engineer who can build features end-to-end - from database schema to API routes to polished React UI. Equity included.

Companies tell our AI what they need - a corporate retreat for 200 a team building in Tuscany a product launch in Milan - and our platform handles the rest: gathering the brief through conversation searching venues processing supplier proposals and managing the entire event lifecycle.

No forms. No back-and-forth emails. Just natural language.

Our stack

TypeScript monorepo (Turborepo Bun) 16 React 19 Tailwind CSS Radix UI PostgreSQL Prisma ORM Mastra Framework Azure OpenAI (GPT-5.2) AWS ECS.

The Team

Were 9 people total - 4 founders and 5 team members. Two co-founders work on the product daily: Lorenzo (CTO) and Daniele (CPO). The engineering team is Lorenzo and a Founding Engineer. Youd be the third engineer working directly with both co-founders.

How We Work

• Ship daily: CI/CD goes straight to ECS. Your code hits production the same day.
• AI-first: We build with Claude Code Cursor whatever makes us faster. Well give you a Claude Code subscription or the AI tool you prefer.
• Pragmatic: Simple solutions DRY code iterate based on real usage. No over-engineering.
• Flexible: Core hours 9:15-18:15 CET. We care about output.
• Fast: Slack message > meeting. Always.

Tasks

Why This Role

Were building a platform where AI agents handle real business workflows - and every feature touches the full stack: database models for event data API routes that orchestrate AI workflows and React interfaces that stream results in real time. Youll work on proposal management systems venue search with live updates conversational UIs and complex data management - all powered by AI underneath.

You wont be siloed. Youll own features from database migration to production UI.

What Youll Do

You wont be experimenting in a notebook. Youll be building and shipping to real customers.

First month - Learn the system ship real things:

• Understand the codebase: monorepo structure shared packages how AI streaming reaches the UI
• Pair with Lorenzo on existing features - fix bugs improve API routes refine UI interactions
• Ship your first end-to-end feature to production

Months 2-3 - Build independently:

• Design database schemas (ZenStack/Prisma) and write migrations for new features
• Build API routes with proper validation (Zod) pagination and error handling
• Create React pages and components that integrate with AI streaming
• Own features end-to-end: from data model to API to UI

Months 3-6 - Own entire feature areas:

• Architect complex features from scratch (real-time streaming drag-and-drop interfaces multi-step forms)
• Build integrations with external services (email document processing third-party APIs)
• Improve developer experience: shared packages type safety across the monorepo
• Start shaping what we build next not just how

After that - Youre one of three engineers building the product. Youll have opinions on architecture push back on ideas that dont make sense and drive features from we should do X to production. The scope grows as fast as you do.

Whats Already Built

Were not pre-product. We have a mature codebase: 40 AI agents across 5 major workflows 30 reusable UI components 20 custom hooks a streaming event system for real-time AI updates and complex data management interfaces (proposals pricing venues). Real customers use it today.

Youll work in a TypeScript monorepo: web app with App Router Mastra Hono AI service shared database and streaming packages - all deployed on AWS ECS.

Requirements

Must-have (MANDATORY):

• 5 years building software with strong full stack experience
• App Router production experience ( 15)
• React 19 expertise with complex state management (custom hooks context)
• TypeScript at an advanced level (generics Zod type inference)
• PostgreSQL and ORM (Prisma or similar): schema design migrations query optimization
• API design: RESTful APIs validation pagination error handling
• Tailwind CSS: responsive layouts component styling
• Component libraries (Radix UI shadcn/ui or similar)

Non-negotiable:

• Italian: native/fluent - customer-facing work requires it
• English: strong - docs research team communication
• Based in Italy remote

Nice-to-have:

• AI/LLM integration experience (prompt engineering streaming APIs)
• Mastra Framework or similar agent orchestration tools
• Monorepo tooling (Turborepo Bun)
• Real-time data (Server-Sent Events WebSockets streaming)
• AWS (ECS S3 Lambda) Docker Terraform
• Testing frameworks (Jest React Testing Library Playwright)
• Observability (Sentry OpenTelemetry)
• Figma proficiency

A heads up: this is a startup. Youll be in the trenches with us. Some days youll solve problems no one has solved before. Some days youll have to figure things out from scratch with no playbook. Ownership is total - from database schema to production UI its yours. Its not easy but if you want comfort and hand-holding this isnt the place.

Benefits

• 55-65k RAL
• Stock Options: we are a seed startup and joining now means you could make a huge amount of money if we make it
• Private Health Insurance (Generali). Its a pretty good one
• Fully remote in Italy. We have an office and you are welcome to join but thats up to you (no pressure at all)
• MacBook Pro as your company device
• Claude Code subscription (or AI tool of your choice)
• Direct product influence. In a team of 10 everything you build matters
• Youll build the full stack of the first humanless event agency in Italy - and shape where it goes

Tell us about a feature youve built end-to-end that youre proud of - from database to UI. Share your GitHub portfolio or anything that shows how you think about building software. Wed love to hear from engineers who enjoy owning the full picture.
