Founding Senior Software Engineer – Construction Tech Platform Location: Turin, Italy (Hybrid) Compensation: Competitive salary + founder-level equity About the Company We have partnered with an early-stage startup based in Turin, on a mission to transform how buildings are designed and delivered. Their platform is redefining collaboration and efficiency in the construction industry, a space ready for true digital disruption. They're backed by experienced founders from design, software, and construction backgrounds, and we’re now looking for our Founding Senior Software Engineer to join them on this journey. This is a hands-on, high-impact role where you’ll work directly with the cofounders, shape the product architecture, and lay the groundwork for the engineering culture. If you want ownership, challenge, and the chance to build something truly new, this is it. What You’ll Do Own core product development: Build and optimize a fast, scalable backend and intuitive, high-performing frontend. Design architecture from scratch: Lead system design, database schema modeling, and API architecture. Develop type-safe APIs using Next.Js and TypeScript, connected to PostgreSQL via Drizzle ORM. Shape beautiful, reusable UI components using React, Radix UI, Tailwind CSS, and React Query. Ship fast and often: Work end-to-end on new features — from concept and prototype to live product. Collaborate directly with the founders: Your technical input will influence the roadmap, business strategy, and hiring as we grow. What We’re Looking For Deep experience with React (v19), Next.Js (App Router), and Tailwind CSS. Strong backend knowledge, particularly PostgreSQL or other relational databases. Familiarity with Git, CI/CD pipelines (GitHub Actions), and cloud infrastructure (Vercel, AWS EC2/S3 ). A hands-on builder comfortable in ambiguity — you thrive in the zero-to-one phase. 3+ years of software engineering experience and/or a Computer Science or similar technical background. Passion for clean, maintainable code, scalability, and product quality. Premio Points For 3D / WebGL experience (Three.Js, Autodesk Viewer). Real-time communication experience (WebSocket, Socket.IO, ws). Email service integrations (SendGrid, Resend, Postmark, Nodemailer). Auth & RBAC systems (Clerk, NextAuth). Tech Stack Frontend: Next.Js App Router, React, React Query, Tailwind CSS, ShadCN, Radix UI Backend: PostgreSQL with Drizzle ORM, React Server Actions 3D Engine: Autodesk Viewer, Three.Js Dev Tools: GitHub, Vercel, Neon, Figma Why Join them: Be a true founder: Build from the ground up and directly shape the technical and product vision. Ownership & growth: Get meaningful equity and grow into a future CTO role. End-to-end impact: Every line of code you write will shape how construction happens in the real world. Tight-knit team: Work closely with experienced founders, not layers of management. Purpose-driven mission: Help digitize one of the most vital — yet least modernized — industries on the planet.
