Are you our next Senior Data Engineer?

If you’re a Senior/Lead Data or Backend Engineer passionate about a chance to contribute to the technical decisions and data infrastructure around the IoT products providing a greener, fault-free future for our railways, this role might be a great fit for you!

About us

CEMIT is a data intelligence company with ambitions to lead a digital transformation of the railway industry globally. As a scale-up supported by top-tier investors, we are a dynamic and customer-centric organization with R&D at the core of our DNA. Our platform collects data from railway infrastructure and uses ML and analytics to provide real-time insight into the health of the trains and tracks to drastically improve maintenance efficiency and rail uptime. Together we are leading an intelligent shift that will increase the reliability, affordability, and efficiency of rail transportation, enabling a greener future.

Today we collect data from more than 30,000 km of railway every day, positioning us at the forefront of data intelligence for the railway industry. By winning Eurostars in 2022 we were recognized as the most innovative SME in Europe amongst 432 finalists.

We are an international team with headquarters in Skien, Norway, and offices in Oslo.

About the role

We are now seeking a Senior Data Engineer with expertise in creating a scalable and robust data platform alongside creating some APIs to expose data pipelines, models, and insights to other systems. We already have a strong product in the market with customers and users on three continents. However, as we are growing from a startup of 17 people to a global SaaS company, we need to further enhance our data-heavy platform. Therefore, we are looking for a new team member to help us enable our vision for future data intelligence in the railway industry. In this role, you'll work closely with a small, cross-functional team to define, build, and improve solutions, ensuring a smooth, end-to-end user experience. If you're passionate about data and want to help shape the future of railway tech, we’d love to have you onboard!
