Mason

Mason builds AI systems that accelerate the development of the built world, addressing housing shortages, energy constraints and decaying infrastructure by speeding up how real-world projects get planned, approved and built. The company's platform is deployed with some of the largest developers, REITs and asset managers in North America, where it directly shapes how billions of dollars of projects move forward rather than producing demonstrations.

Technical work spans artificial intelligence, machine-learning systems, software engineering and the physical domains of construction technology, real estate development and infrastructure. Teams optimise for leverage, speed and production-grade systems, and take responsibility for outcomes rather than incremental features. Annualised revenue quadrupled in March, and the company points to decades of combined experience across AI, technology and physical development; one development director on the team has built more than $2bn of projects.

Mason operates as a small, elite team offering real ownership from day one. Compensation includes competitive salary and equity packages, comprehensive health, dental and vision insurance, flexible hours and remote work options, generous paid time off and parental leave, and professional development opportunities, within a collaborative and inclusive environment. The work is focused on North America and on real estate, construction, housing, infrastructure, energy and asset management.
