Senior Full-Stack Engineer

Maestro is a startup born from research at MIT and the University of Cambridge. Our mission: use software to change the way we build—turning design data into clear, real‑time instructions for the people (and soon machines) that assemble our world. Product Maestro Pilot is a web-based tool that converts BIM/CAD models, engineering inputs and site feedback into interactive 3‑D assembly manuals for crew & real‑time completion tracking for the client. Proof We bootstrapped our business by proving the advantage of our technology in the field. Since launching 24 months ago, Maestro Tech has built mass‑timber and steel projects in Europe and the United States. Real‑time coordination on those jobs slashed re‑work, compressed schedules, and cut carbon. Next Manufacturers are lining up for enterprise trials. We’re expanding the software team to ship the next‑gen Pilot and make digital assembly the industry default. Join us early—you’ll ship code that lands on active job‑sites, learn fast, and help rewrite the playbook for how buildings get made The Product Maestro Pilo is: a web platform that converts models, engineering, and site feedback into interactive 3D manuals and real‑time completion tracking. Our platform digests massive BIM models, uses AI to generate logical assembly sequences, and visualizes them in a custom 3D engine. We are building the operating system for the next generation of construction. What you will solve You will architect a Single‑Page Application (SPA) that seamlessly integrates a custom high‑performance rendering engine (handling 1M+ objects). You are the bridge that connects massive geometric datasets to the user’s fingertips. Core CompetenciesModern UI Architecture: You understand the “physics” of the frontend: VDOM diffing, memoization, reconciliation, batching, and scheduling. While we use React (including SSR/RSC + Hydration), we value the fundamental understanding of how to control rendering strategies, change detection, and reactivity above all else. Complex Data Visualization: Experience rendering and managing state for huge chunks of data presented in diverse forms: datagrids, interactive flowcharts, and 3D overlays. You are comfortable using virtualization, lazy loading, and caching to keep the UI native‑feeling. Advanced State Management: Mastery of mutability vs. immutability. Whether using Redux, Zustand, or XState, you know how to manage granular reads (selectors) and handle complex async middleware. Database Theory & SQL: A theoretical and practical grasp of SQL internals (Joins, Indexes, Transactions). You know how to optimize for synchronous query execution to feed data rapidly to the frontend. Algorithms & Data Structures: Since we deal with BIM data (Graphs, Trees, Adjacency Matrices), you must be comfortable with traversal algorithms (DFS/BFS) to manipulate project structures efficiently.What you will doArchitectural Migration: Lead the strategic transition of our platform from a Multi‑Page Application (MPA) to a high‑performance Single‑Page Application (SPA). Cross‑Functional Collaboration: With the Graphics Lead: Manage the bi‑directional data flow between the React UI and the custom Three.js rendering engine. You will ensure that UI overlays (annotations, selection menus) stay perfectly synced with the 3D canvas state. With the AI Engineer: Visualize the output of our AI agents. You will build interactive chatbots implementing advanced streaming techniques and artefacts rendering. Performance & Optimization: Conduct rigorous benchmarking and A/B testing. You will actively audit and reduce reliance on third‑party libraries, preferring custom, lightweight implementations.The Reality of the RoleMorning: Collaborating with the Lead Graphics Engineer to optimize how metadata is passed to the 3D viewer, ensuring that clicking a “Beam” in your React datagrid instantly highlights the object in the 3D canvas without dropping frames. Mid‑Day: Optimizing a recursive SQL query that fetches hierarchical project data, ensuring it fits within a single transaction. Afternoon: Refactoring a heavy flowchart component moving from a bloated library to a custom SVG implementation to improve performance.What we offerReal ownership.
