Senior Product Engineer Full-Stack 3D Visualization - Selection Book

Remote | Full-time Contractor Preferred location: Latin America (Colombia, Mexico, Brazil, Argentina) Portfolio or GitHub required

A fast-growing North American manufacturer of premium window and door systems is hiring a Senior Product Engineer to own the development of internal tools, a public-facing website, and — most critically — a high-performance interactive 3D product visualization platform built from scratch.

This is a high-ownership, solo-contributor role. You will design and ship real systems end-to-end, working directly with leadership. There is no engineering team beneath you. If you enjoy full ownership and building systems that teams and customers rely on every day, this role is for you.

Compensation

Contractor Monthly Salary in USD payment via Deel

Fully remote, flexible working hours

Paid monthly via international contractor payment

We cover the cost of any developer or AI tools you need (Claude, Cursor, Codex, etc.)

Top candidates will have the opportunity to grow with the engineering team as it expands

About the Company

A privately held manufacturer with operations across North America, specializing in premium architectural window and door systems . The company designs and builds its own products and is now developing the internal software platforms, visualization tools, and digital experiences that will power its next stage of growth. The engineering team is small, the decisions move fast, and the person in this role will have direct impact on how the company operates and sells.

What You'll Build

🪟 Product Visualization Platform (primary focus)

You will build from scratch an interactive, web-based 3D visualization tool that allows customers to configure and explore complex architectural products. This is the most technically demanding part of the role.

Requirements:

True 3D rendering — no 2D models stacked on separate planes

Correct pivot point calculations for product movement and mechanical behavior

Toggle between styles, colors, materials, and sizes with parametric scaling

Texture and model compression for sub-second load times — "send the recipe, not the dish"

Smooth real-time rendering as product options are changed

Integration between UI state and the visualization engine

The 3D assets will be provided by designers. Your focus is engineering, architecture, and performance.

Note on background: We're especially interested in candidates with experience in gaming or game engine environments (Unity, Unreal, etc.) — not because the tool must be built on a game engine, but because that background produces engineers who think in 3D transformations, physics, and optimized rendering. That said, any engineer who can demonstrably build a performant 3D configurator will be considered.<
