Technical Lead

About Sedes

• Sedes is an AI-native property operations platform, cross-asset by design for real estate operators in Europe and abroad.
• Tenants talk to us entirely over WhatsApp: an AI agent handles maintenance requests, scheduling, and questions end to end, escalating to human operators when needed.
• Our goal is to create a Digital-Twin of all properties within a portfolio, so our Agents together with operators may orchestrate everything: rentals, obligations, compliance, cleaning and maintenance planning, and tenant communication.
• Live in production with paying clients; we are a Meta WhatsApp Tech Provider.

The role

• Our current technical lead is transitioning out and will run a full structured handover with you.
• You will inherit a working, revenue-generating product and own it completely: architecture, roadmap, delivery, and eventually the engineering team.
• This is a true #1 technical seat. Depending on fit, this role becomes CTO.

What you'll own

• A Next.JS 16 / React 19 dashboard (TypeScript, TanStack Query, Zustand, Tailwind v4) on Vercel
• A serverless API: 14 Express-on-Lambda microservices (Node 22, TypeScript) behind API Gateway, Cognito auth, EventBridge scheduling, all on AWS eu-south-1
• Supabase Postgres with PGVector RAG; no ORM, typed data layer
• The AI core: an OpenAI Agents SDK orchestrator with ~35 tools and 4 personas, multi-provider
• model routing (OpenAI + Gemini via Vertex), eval harnesses with LLM judges
• WhatsApp Cloud API integration: templates, webhooks, encrypted Flows
• A separate document-AI platform (Bun/TypeScript, CDK, Qdrant, MinIO, ERPNext) that extracts
• structured financial data from ingested documents

What you'll do

• Ship product weekly across the full stack; this is a hands-on coding role
• Own reliability of a system real tenants depend on daily
• Mature the engineering foundation: CI/CD, E2E testing, and deploy automation currently don't exist, and we'll be honest that this is your first 90 days
• Drive the AI agent roadmap: new tools, personas, eval coverage, model routing
• Work directly with founders and clients to turn operator pain into features

You Must have

• Senior TypeScript, full stack (our entire codebase is TS)
• AWS serverless in production (Lambda, API Gateway, Cognito, IAM) Shipped LLM-powered features to real users: agents with tools, RAG, evals. This is core product, not a bolt-on Postgres fluency.
• High agency: you have run systems where you were the last line of defence

Bonus points

• WhatsApp Cloud API / Meta platform experience
• Multi-tenant SaaS design
• CDK / Docker / EC2 ops, ERP integrations (ERPNext/Frappe)
• Italian language or Italy market context
• Comfort with AI-assisted development workflows (we build with Claude Code daily)
• Prior founding or first-engineer experience Open problems you'd tackle
• Zero-to-one CI/CD and E2E testing across three repos
• Agent reliability: eval coverage and regression gating for a 35-tool orchestrator
• Replacing scheduled-sweep patterns with proper queueing as volume grows
• Scaling multi-tenancy from a handful of clients to dozens
