Senior Full Stack Engineer for CubiCasa Tour

About the Project

At CubiCasa, we are rewriting the rules of real estate visualization. Our flagship interactive feature, CubiCasa Tour, bridges the gap between static floor plans and property photography. Using our AI photo matching engine, the platform automatically positions listing photos to precise locations and camera angles on an interactive 2D floor plan. Give a spin for our example Tour. Our tour product receives over 3 million visits per month.

Because this product is heavily utilized by homebuyers on real estate portals around the world, the mobile web experience is our absolute priority. We are looking for a Senior Full Stack Developer who pairs robust backend engineering in Go with an extraordinary eye for detail and design execution on the frontend using reactive frameworks (the project is not currently using any reactive framework, but will in the future)

Key Responsibilities

• Craft Immaculate Interfaces: Own the frontend implementation, translating high-fidelity designs into pixel-perfect, fluid, and highly interactive mobile web experiences.
• Optimize for Mobile First: Ensure touch gestures, zooming, photo carousel, and transitions feel natively smooth on iOS and Android mobile browsers.
• Build Scalable APIs: Design, develop, and maintain high-performance, low-latency APIs for the tour and auxiliary products.
• Cloud Architecture: Leverage AWS services in collaboration with our devops team to ensure our infrastructure is secure, auto-scaling, and optimized for global content delivery (CDNs, edge computing, caching).
• Maintain Visual Quality: Act as a bridge between design and engineering, catching the micro-interactions, layout shifts, and rendering details that turn a good UI into a perfect UI.

Technical Requirements

Frontend & UI Execution

• Reactive Expertise: Production experience with reactive framework and TypeScript, with a deep understanding of reactivity model.
• The "Eye for Detail": A proven track record of delivering flawless UI. You care about consistent spacing, smooth cubic-bezier transitions, and preventing layout jank.
• Interactive Web Graphics: Hands-on experience working with SVG manipulation and web graphics.
• Mobile-First Mindset: Deep knowledge of mobile web performance profiling, touch event handling, responsive layout constraints, and cross-browser quirks (eg Safari iOS vs. Chrome Android).

Backend & Infrastructure

• Go (Golang): Strong professional experience writing clean, idiomatic, and concurrent code in Go.
• AWS Ecosystem: Solid understanding of AWS infrastructure (e.g., EC2/ECS, Lambda, S3, CloudFront, RDS/PostgreSQL).

Nice-to-Haves

• Experience with WebGL, vector graphics optimization, or map-based interfaces (Leaflet, Mapbox).
• A portfolio or examples of past work demonstrating exceptional visual execution and micro-animations.
