Adaptis is a clean-tech company that helps organizations optimize both carbon and cost across the entire lifecycle of their buildings—whether for a single asset or a full portfolio. Our platform supports data-driven decision-making from design through operation, enabling teams to reduce emissions, manage risk, and meet sustainability targets efficiently. At Adaptis, we are driven by the mission to accelerate decarbonization in the built environment through practical, scalable solutions.
We're seeking a Full Stack Developer to help build and scale our decarbonization platform from the ground up. You’ll play a critical role in shaping both the architecture and the user experience, working closely with design, product, and climate domain experts to bring powerful tools to life.
The ideal candidate is a pragmatic problem-solver with a strong foundation in both front-end and back-end technologies. You’re comfortable working across the stack, excited to ship quickly, and experienced in navigating the dynamic, fast-paced nature of an early-stage startup.
You will be joining an eager and focused team of 3-5 engineers and data scientists bringing the Adaptis core product to market. This role will be putting ground breaking carbon reduction AI & ML into the hands of our users. You will be expected to build and own end-to-end products across our stack. We iterate quickly, adapting to our user needs, and our development efforts reflect that.
This role requires individual ownership, a growth mindset, as well as mentoring and bringing best practices throughout our team.
You will need to be able to handle change, work in a fast paced environment, and take initiative.
Our stack is Node (with Express), React (with Vite), Python (with FastAPI) and MongoDB.
We understand that AI tools are now part of how we work, write, and create. If you’ve used AI to help draft any part of your submission materials, we just ask that you briefly let us know which parts were AI-assisted. This helps us better understand your process and evaluate your work fairly.
Transparency matters more to us than perfection. Thanks for being upfront.
We are a distributed, hybrid team working from different cities in Canada. It is preferred that candidates for this role be located in Toronto and available up to 80% in person in our downtown office.
Please fill out our form here to apply.
Note that we will review all applications and reach out to you directly only if there is a fit to move forward.
