Lead Full-Stack Developer — Rebuild and Lead a Modern ERP SaaS Platform
We’re building a next-generation ERP SaaS platform for the construction industry—a powerful, multi-tenant system that combines time tracking, project management, and real-time jobsite analytics into one seamless experience. The product is being rebuilt from scratch with a new design, clean architecture, and modern stack. As the first developer on a growing team, you’ll help architect the system, guide how it takes shape, and build the team that builds the future—alongside other A++ professionals who want to change the industry and grow in the process.
About Masonry Group
Masonry Group is a well-established Canadian construction company delivering over 2,000 residential and commercial units per year. Since 2009, we’ve earned a reputation for precision, professionalism, and reliability.
The initial version of this product was developed by an external development agency; however we are now bringing the entire development process in-house.
Now, we’re channeling that real-world experience into a tech product that will change how construction companies operate. This isn’t an internal tool—it’s a standalone SaaS product designed for the global construction industry, built by a tight-knit team of builders, engineers, and product thinkers.
Position Overview
We’re looking for a strong Middle or Senior level full-stack developer to join us in rebuilding our ERP system from the ground up.

You’ll be the first hire in a growing product development team, working alongside our founder, designer, and a fractional CTO. As soon as you’re hired, we’ll begin expanding the team based on your input—whether that’s frontend, backend, or full-stack roles. You’ll help define the tech stack, lead development, and shape how the product evolves.
