Why we're here
At Hakio, we combat global waste in logistics, production, and consumption of fashion – and our weapon of choice is data. We build advanced forecasting models and a platform that, when combined, help brands like Hummel, Carhartt, and Organic Basics make better, faster, and more accurate decisions. This reduces overproduction and avoids lost sales due to poor stock visibility.
It’s good for business, and great for the planet.
And we’re a startup, meaning we’re always evolving. We think change is exciting - it keeps us on our toes. While some of us love sticking to a good plan more than others, a common trait is that we’re not afraid to shake things up when we learn something new.
Let's talk about you!
You always seem to find a solution to problems at hand. The more complex, the more fun it is for you to dig into. You’re a person of action, practical in your solutions, and you’re intuitively great at navigating your way through chaos.
You like being surrounded by talented teammates who push you to do your best. It’s simply more fun that way.
Your responsibilities:
You thrive under a deadline, and you keep going until you’ve done what you set out to do. People trust you because taking ownership comes naturally to you. At Hakio, you’ll be motivated by responsibility to:
- Build and maintain our core web application using React in the frontend and our Python-based API.
- Collaborate with the team to continuously deliver end-to-end customer value.
- Develop features that elevate the customer experience.
- Partner with our designers to ensure a consistent UI approach in the application.
- Ensure optimal performance and quality of the platform.
You'll thrive here if you have:
- High proficiency in Typescript with experience working in React.
- Experience building and maintaining an API with a high focus on performance when handling large amounts of data.

- Great communication and collaboration skills - you enjoy talking your way to solutions with sharp teammates.
