Would you like to combine crisp code with saving the climate?

At The Ontology Way we fight climate change by helping our customers keep track of and reduce their emissions. We make emission data collection streamlined, and provide clean visualizations and analyses of any companys emission profile. At the heart of our technology this is solved by creating a whole-company digital twin, which is exposed to customers as a SaaS offering. Right now our immediate goal is to launch a pilot product, and we're looking to extend the team with additional developers.

As a small but growing company we're looking for a java/scala developer to shape and refine our core digital twin software. It is great if you are enthusiastic about compilers, graph databases and reasoning about what things truelly are, but also require code to be readable and tested.


We value :

  • Openness to new ideas and technology

  • Putting others first

  • Incremental improvement


What we offer:

  • A real possibility to change the world for the better.

  • Great influence over the software foundation.

  • A creative environment with a focus on innovation.

  • A decent salary and equity in the company.

  • An open-minded and relaxed atmosphere where any thought can be ventilated and discussed.

  • A workplace where the well-being of the team is highly prioritized.


Our journey is at an early stage; we are currently just a few employees and we've just received initial funding, but in the future, we see ourselves as a global SaaS company, facilitating business collaboration to accelerate all the UN sustainable development goals. Our first focus, however, is Responsible Consumption and Production (12), Climate Action (13) and Partnership for the Goals (17).

Sustainability permeates everything we do, from how we furnish our office and encourage our employees to be their whole selves to how we design our license model and choose our KPIs. We believe in a flat organization inspired by Teal principles and an infinite game!

Working at
Emission Twin

Emission Twin helps companies achieve their climate goals—not just report on them. Our cutting-edge software centralizes climate data, turning insights into action and making sustainability a growth driver rather than a compliance chore. We help CFOs, sustainability managers, and decision-makers turn numbers into real impact. Climate reporting is essential, but let’s be honest—it doesn’t solve the climate crisis. Too many businesses get stuck in reporting loops instead of making real impact. We bridge that gap with a smart, user-friendly platform that analyzes, strategizes, and automates climate efforts, helping decision-makers move from obligation to opportunity. We built Emission Twin because we saw a world where sustainability could be effortless, impactful, and valuable. The climate crisis won’t wait, and neither should action. With the right tools, businesses can lead the way and we’re here to make sure they do.
