Mid-Level Software Developer (AI-Focused)

At Cresa, we believe our clients deserve better. A better space to work, create, build, grow. A better outcome for their people and organization. A better partner who puts their needs first, helping them navigate the landscape, tilting the playing field in their favor and giving them an insider’s edge.

Our mission is to find and foster the best environment for every business. Our purpose is to think beyond space - strengthening those we serve and enhancing quality of life for our clients and employees. We are built to champion our clients’ aspirations through real estate. When considering partnership, we strive to connect with those who share our values: Work Together, Create Value, Be Tenacious, Enhance Community, and Embrace Diversity.

We believe in being the change. We work together to find new ways of doing things that create value for our clients — and for each other. Because there is not much that feels better than collaborating to make a positive difference each day.

At Cresa, we offer an opportunity to be part of something bigger. To learn, advance, mentor and be recognized. Your voice will be heard, and you will be valued for both your individual and team contributions.

We’re building modern enterprise software for commercial real estate management, combining robust systems engineering with intelligent automation. Our platform helps companies with large commercial real estate portfolios manage lease administration, lease accounting, capital projects, and portfolio strategy, and now we’re pushing deeper into AI-driven capabilities.

We’re looking for a mid-level developer who’s passionate about applying AI and large language models (LLMs) to real-world enterprise software challenges. You’ll play a hands-on role in both integrating AI features into our product and leveraging AI tools for software development itself.
