Over the next five years, most of the world's major governments and corporations are going to need to build climate sustainability into their procurement, operations, and reporting.  That's our job -- and it could be yours, too.

We already develop and operate Building Transparency's EC3 tool, the world’s most popular SaaS platform for tracking the climate impact of construction materials.   It is also the basis of enterprise platforms used by several major multinationals worldwide.   

We created and manage the open standards for digital environmental product declarations (openEPD) and a wide range of engineering and business integrations, and have cultivated an ecosystem of sustainablity tool developers that rely on Building Transparency and C-Change for their underlying data.


Professional Growth

We maintain an open culture. Achievements are appreciated; achievements over your role and helping your co-workers succeed are key to advancement. Mistakes are expected, and are to be openly discussed and learned from. Honesty is an absolute requirement.

You will be surrounded by a group of passionate engineers who are happy to participate in technical discussions.

You will always have access to advice.  Your supervisor will be a senior programmer; your team-mates will help you as well.  We expect you to help your co-workers in the same way.

There will be opportunities to lead projects, mentor junior devs, and expand your skill-set if desired.

Working Space

We are an all-remote team located in Canada and Ukraine.  We have no traditional office space. However we will be happy to help you organize and equip a safe and effective working space.

Health & Wellness

We offer competitive benefits for all staff. They are structured differently in each country; in Canada we offer extended health and dental benefits through Manulife.


We encourage a healthy work/life balance: we do not believe routine overtime is a good way to do business.

All roles get at least three weeks paid time off, as well as paid sick leave.


Competitive compensation matching the market. Compensation reviews are tied to your growth and improvement.

Short Decision Making Chain

Every team member is a direct contact with CEO and CTO.  Decision making is rapid and it is easy to escalate issues.
