Job description

We’re on a mission to help enterprises build, operate, and scale intelligence they own to solve the problems that matter most.

Langstack is an operating stack for the digital and physical world that unifies infrastructure, organizational knowledge, AI models, and autonomous agents in one secure environment.

We’ve been around for more than a decade, but in many ways we’re still a startup. We’ve raised €1.8M over the years and became profitable several years ago.

Why consider Langstack

As a Student Software Engineer, you’ll join a small international team of driven, enthusiastic, and friendly people with an average age closer to 50 than 25. A few of us began our computing journeys with a Commodore PET, while others started on an Amiga 500, to provide some context.

Your role will span our key business functions:

• In our consulting team, you’ll develop solutions for our large customers in the energy, telecom, and financial sectors using TypeScript, Python, and, of course, Langstack.
• In our product team, you’ll develop new features using React and Node.js for the Langstack product line.

Here are a few things worth mentioning about working at Langstack:

• We pay competitive salaries. Our compensation is not at the market’s peak, but well above its bottom.
• The position offers a wide range of responsibilities, from hands‑on coding and solution design to managing smaller projects end‑to‑end. You’ll work both independently and in close collaboration with other team members. For the right candidate, there will be plenty of opportunities to grow professionally.
• We’re a remote team working together with a high degree of flexibility. We use Discord as our digital HQ and meet at locations in Copenhagen, where most of us live, whenever necessary. As part of the team, you can organize your time and structure your work in a way that best fits your studies.

You’ll be expected to meet high professional standards. We’re committed to building software that delivers real business value. We’re renowned for delivering impactful results for our clients, and we take great pride in our work.

Last but not least, we’re united by a shared drive to develop products that tackle complex challenges. Joining our team places you at the heart of shaping the next era of intelligent computing.

Qualifications

• Nearing completion of a bachelor’s degree or actively pursuing a master’s degree in Computer Science or a similar technical discipline, or holding equivalent practical experience
• A solid understanding of web development and REST‑based application design, with a proven track record of building single‑page applications using React, Next.js, or Angular
• Familiarity with version control systems
• A strong grasp of data structures and data processing
• A systematic, well‑structured approach and the ability to work independently
• Proficiency in Danish and residency in Denmark are a plus

Our process

This is our hiring process:

• Preliminary online interview
• Online technical interview with our CTO and an observer from the team
• Final interview at a location in Copenhagen or online
• You made it. A warm welcome to the team

We welcome unique perspectives and experiences in shaping Langstack and encourage people from all kinds of backgrounds to apply.
