KAKTI is on a mission to accelerate the transition toward affordable and intelligent energy systems. Our AI-powered energy management platform optimizes the operations of district heating plants, making energy production more efficient, responsive, and climate-friendly.

At our core, we're a collaborative, impact-driven, and technically ambitious team dedicated to transforming how heat and power are produced and consumed.

Real-Time LCA is a powerful platform that enables companies to understand, reduce, and document the climate impact of their building projects during design and construction. 🏘️ By automating LCA calculations, it reduces the effort required for impact assessments by 50-90%. Users can perform collaborative, efficient, and accurate Life Cycle Assessments (LCA) that comply with international standards, certification schemes, and regulations. The platform streamlines LCA processes from BIM to reporting, allowing all stakeholders to visualize, track, and document carbon emissions to meet regulations, reported through our standard templates, or leverage your sustainability data in other applications through our API. 🙌

CETO Innovation is developing a predictive maintenance solution for district heating networks, combining an in-pipe probe with data-driven failure predictions. Our technology enables early detection of pipeline issues, reducing downtime, maintenance costs, and energy waste while optimizing infrastructure management. We are addressing the challenges of aging district heating infrastructure, where reactive maintenance leads to inefficiencies and unexpected failures. By integrating real-time data analysis with in-pipe diagnostics, we aim to provide a smarter, more sustainable approach to pipeline management.

Many people are talking about the smart grid and how we can reach 100% sustainable energy, and avoid global warming getting out of hand, by intelligently balancing the consumption so it fits with the electricity production. At True Energy we're already doing it! True Energy offers a smart charging app to our end users so they can register their car or charger and have it start or stop charging based on the hour of day and the electricity price, so the user optimizes their charging to be cheapest. The service is free of charge for the end user because they participate in our flexibility pool where the power companies can buy offsetting of the consumption if the grid is overloaded or production is expensive. We use Google Workspace, GitLab as code repo, Jira for our agile project management, and Slack for chat. We have a policy of 100% line coverage for unit tests, and want to support continuous delivery. We focus on collaboration and an open, inclusive work environment. Our team is multinational, and the working language is English, so full proficiency is required.. We have team members in several time zones.

What is RE-ZIP RE-ZIP is a circular packaging concept offering circular packaging to more or less all players in the ecommerce industry. By circulating and hence reusing rather than using single-use packaging (even recycled) we save CO2 even the first time a packaging is reused. It works likes this RE-ZIP delivers the packaging to webshops who offer the sustainable packing solution to their customers at check-out for a minor fee (paid back via reward voucher upon returning the packaging). Upon receipt of the goods the customer folds the RE-ZIP packaging to a return format and return it at a Drop Point. The packaging is returned to the RE-ZIP warehouse for cleaning and re-circulation to the webshops. The RE-ZIP packaging can be circulated up to 10 times, but more importantly the packaging will begin saving CO2 Within the first or second use – depending on the type. RE-ZIP has developed a state-of-the-art backend system supporting the above process and are currently operating in Denmark, UK and Poland. Hence working at RE-ZIP will offer you in-person colleagues in Denmark and remote colleagues in before mentioned countries and more to come. Working at RE-ZIP Working from the Danish RE-ZIP HQ you will find a bunch of nice new co-workers who appreciate to work from the office most days, because the energy we create together is important for us.

Send us your application to come join us in our mission to change e-commerce packaging for good.
