About Adaptis

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 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.

Background and Preferred Qualifications

We are looking for engineers with 5+ years of experience to help us scale our product.
Extensive experience delivering full-stack features in a fast-paced SaaS environment using Typescript, Node, React, and MongoDB
