Job description

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

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.

Internal Tools

Software used daily by teams across sales, marketing, and production:

• Production workflow and scheduling dashboards
• Sales and marketing analytics tools
• Automation connectors between internal systems and APIs

Website Platform

• Maintain and evolve the public-facing website (currently on Webflow )
• Build product and landing pages
• Integrate the visualization tool into the website
• Performance-optimized frontend architecture and SEO

Tech Stack LayerTechnologies

• Frontend: React (TypeScript), Tailwind CSS
• Visualization: Three.js / WebGL, D3.js, SVG / Canvas, ECharts / Recharts
• Backend: Node.js or Python, REST APIs, SQL databases
• Infrastructure: AWS (EC2, RDS, S3), CI/CD pipelines, Docker (nice to have)
• CMS/Website: Webflow
• 3D Formats: OBJ and similar; texture + model compression pipelines

AI-Native Development

The team actively uses AI tools as force multipliers and expects you to do the same:

• Claude, OpenAI Codex, ChatGPT, Cursor
• AI-assisted IDE workflows for code generation, refactoring, and debugging
• All tools will be covered. Candidates already working AI-natively are a strong plus.

What We're Looking For

Must-have

• 4+ years of full-stack engineering experience
• Strong JavaScript / TypeScript
• Experience building and shipping production web applications independently
• Ability to own projects end-to-end with no hand-holding
• Strong communication: proactive updates, early escalation of blockers, sense of urgency on bugs
• Remote-first discipline: available Mon–Fri, 9am–5pm EST for collaborative hours

Strong plus

• Experience with Three.js, WebGL, or any real-time 3D rendering framework
• Background in gaming development (Unity, Unreal, or similar)
• Experience building product configurators or interactive visualization tools
• Familiarity with 3D model compression and optimization (LOD, texture atlasing, etc.)

How We Work

• Small team, direct access to decision-makers
• Projects move fast and are often built from scratch
• Communication is frank, proactive, and async-friendly
• Mistakes are fine — hiding them is not
• We're problem-solvers: bring issues early and we'll solve them together

Hiring Process

• Portfolio / GitHub review (resumes alone will not be considered)
• Short technical conversation
• Paid trial project (4–8 hours): a real problem similar to the role — we pay for your time. Strong candidates may also be asked to walk through how they'd optimize a 3D file's load time and rendering pipeline.
