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!
Problems excite you, and the more complex, the better. You’re all about practical solutions that actually work, and you’re intuitively great at navigating your way through chaos.

You think clearly and confidently, explaining complex issues in a simple manner. That’s your strength. You’re the kind of person who doesn’t just solve problems alone, you help others see them clearly and enjoy working out the solution together.

And last but not least, you have a “focus mode” you turn on when you need to dig deep into something complex and deliver without distractions.

Your responsibilities:
Your teammates trust you because taking ownership and following through come naturally to you. At Hakio, you’ll be motivated by responsibility to:

• Develop and maintain our data ingestion pipeline in collaboration with the team, from integrations with external systems until it reaches our core application.
• Help onboarding customers with large amounts of data by collaborating with them to match their data with our ingestion setup.
• Ensure the code can be deployed on our infrastructure across multiple environments with optimal performance and scalability.

You'll thrive here if you have:

• Experience building, deploying, and maintaining a backend handling large amounts of data with a focus on scalability.
• Strong proficiency in Python and SQL.
• Hands-on experience with tools like BigQuery, Redshift, Synapse, or similar.
• Great communication and collaboration skills - you enjoy talking your way to solutions with sharp teammates.
