Senior Full Stack Engineer

05 ago - Italia
Always Friday

ppWe’re 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. /p pCompanies 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. /p pNo forms. No back-and-forth emails. Just natural language. /p h3Our stack /h3 pTypeScript monorepo (Turborepo + Bun), Next.js 16, React 19, Tailwind CSS, Radix UI, PostgreSQL, Prisma ORM, Mastra Framework, Azure OpenAI (GPT-5.2), AWS ECS. /p h3The Team /h3 pWe’re 9 people total - 4 founders and 5 team members. Two co-founders work on the product daily: bLorenzo (CTO) /b and bDaniele (CPO) /b. The engineering team is Lorenzo and a Founding Engineer. You’d be the third engineer, working directly with both co-founders. /p h3How We Work /h3 ul libShip daily: /b CI/CD goes straight to ECS. Your code hits production the same day. /li libAI-first: /b We build with Claude Code, Cursor, whatever makes us faster. We’ll give you a bClaude Code subscription /b or the AI tool you prefer. /li libPragmatic: /b Simple solutions, DRY code, iterate based on real usage. No over-engineering. /li libFlexible: /b Core hours 9:15-18:15 CET. We care about output. /li libFast: /b Slack message meeting. Always. /li /ul h3Tasks /h3 pbWhy This Role /b /p pWe’re 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. You’ll work on proposal management systems, venue search with live updates, conversational UIs, and complex data management - all powered by AI underneath. /p pYou won’t be siloed. You’ll own features from database migration to production UI. /p pbWhat You’ll Do /b /p pYou won’t be experimenting in a notebook.



You’ll be building and shipping to real customers. /p pbFirst month /b - Learn the system, ship real things: /p ul liUnderstand the codebase: monorepo structure, shared packages, how AI streaming reaches the UI /li liPair with Lorenzo on existing features - fix bugs, improve API routes, refine UI interactions /li liShip your first end-to-end feature to production /li /ul pbMonths 2-3 /b - Build independently: /p ul liDesign database schemas (ZenStack/Prisma) and write migrations for new features /li liBuild API routes with proper validation (Zod), pagination, and error handling /li liCreate React pages and components that integrate with AI streaming /li liOwn features end-to-end: from data model to API to UI /li /ul pbMonths 3-6 /b - Own entire feature areas: /p ul liArchitect complex features from scratch (real-time streaming, drag-and-drop interfaces, multi-step forms) /li liBuild integrations with external services (email, document processing, third-party APIs) /li liImprove developer experience: shared packages, type safety across the monorepo /li liStart shaping what we build next, not just how /li /ul pbAfter that /b - You’re one of three engineers building the product. You’ll have opinions on architecture, push back on ideas that don’t make sense, and drive features from "we should do X" to production. The scope grows as fast as you do. /p pbWhat’s Already Built /b /p pWe’re not pre-product. We have a mature codebase: b40+ AI agents across 5 major workflows /b, b30+ reusable UI components /b, b20+ custom hooks /b, a streaming event system for real-time AI updates, and complex data management interfaces (proposals, pricing, venues). Real customers use it today. /p pYou’ll work in a TypeScript monorepo: Next.js web app with App Router, Mastra + Hono AI service, shared database and streaming packages - all deployed on AWS ECS. /p h3Requirements /h3 pbMust-have (MANDATORY):



/b /p ul lib5+ years /b building software, with strong full stack experience /li libNext.js App Router /b production experience (Next.js 15+) /li libReact 19 /b expertise with complex state management (custom hooks, context) /li libTypeScript /b at an advanced level (generics, Zod, type inference) /li libPostgreSQL /b and ORM (Prisma or similar): schema design, migrations, query optimization /li libAPI design: /b RESTful APIs, validation, pagination, error handling /li libTailwind CSS: /b responsive layouts, component styling /li libComponent libraries /b (Radix UI, shadcn/ui, or similar) /li /ul pbNon-negotiable: /b /p ul libItalian /b: native/fluent - customer-facing work requires it /li libEnglish /b: strong - docs, research, team communication /li libBased in Italy /b, remote /li /ul pbNice-to-have: /b /p ul liAI/LLM integration experience (prompt engineering, streaming APIs) /li liMastra Framework or similar agent orchestration tools /li liMonorepo tooling (Turborepo, Bun) /li liReal-time data (Server-Sent Events, WebSockets, streaming) /li liAWS (ECS, S3, Lambda), Docker, Terraform /li liTesting frameworks (Jest, React Testing Library, Playwright) /li liObservability (Sentry, OpenTelemetry) /li liFigma proficiency /li /ul pbA heads up /b: this is a startup. You’ll be in the trenches with us. Some days you’ll bsolve problems no one has solved before /b. Some days you’ll have to figure things out from scratch with no playbook. Ownership is total - from database schema to production UI, it’s yours. It’s not easy, but if you want comfort and hand-holding, this isn’t the place. /p h3Benefits /h3 ul lib€55-65k /b RAL /li libStock Options /b: we are a seed startup and joining now means you could make a huge amount of money if we make it /li libPrivate Health Insurance /b (Generali). It’s a pretty good one /li libFully remote /b in Italy.
