Remote | Full-time ContractorPreferred 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.
🛠️ 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

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.)
Most important: you can show us something you built yourself — and it works.
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.
