Every day, we connect homeowners with architects and designers through a custom-built ecommerce platform that has been continuously developed and refined over many years. We don’t just maintain a marketing website – we build software. Our team of six engineers owns the entire platform, from customer-facing features to internal tools, search, ecommerce, infrastructure, analytics, and AI initiatives. We value thoughtful engineering, collaboration, and continuous improvement. About the Role We're looking for an experienced Full-Stack PHP Developer who enjoys working across the entire technology stack. You'll build customer-facing features, improve internal systems, help maintain our cloud infrastructure, and use AI to make both our customers and our developers more productive. This role is ideal for someone who enjoys variety. One week you may be optimizing SQL queries or building new ecommerce functionality. The next you might be improving deployment automation, integrating LLMs into internal workflows, or diagnosing production performance issues. This position is best suited for engineers who enjoy improving existing systems just as much as building new ones. While we're constantly building new features and modernizing our technology, we also believe that successful software engineering is about making the right technical and business decisions. Sometimes the right answer is building something new. Sometimes it's thoughtfully enhancing a proven system. We're looking for an engineer who enjoys understanding existing software, improving it where it makes sense, and modernizing it incrementally while balancing business value, maintainability, and risk.  If you're energized by solving complex problems, taking ownership, and leaving a mature system better than you found it, you'll fit right in.

Small engineering team with significant ownership and impact Modernize and improve an established, successful platform Work directly with decision-makers Opportunity to shape our AI strategy and product direction Variety of technical challenges across software development and infrastructure Excellent benefits package If you're excited about building software, improving systems, and helping shape how AI is applied in a real business, we'd love to hear from you.
