NDURE is building the world's first continuous lactate tracker, think CGM, but for lactate. The device streams physiological data continuously, for days at a time, and we're building the software layer that turns that raw signal into something athletes and coaches can actually use, from elite performance to everyday training. This is unsolved territory: nobody has made continuous lactate data useful in real time before, and we're the ones building it first.

We only accept applicants that are EU citizens already living in Denmark or willing to relocate to Denmark. If this does not apply to you, please do not apply. We are unable to assist with visas.

Key Outcomes

• Design the core architecture of the application, data, backend, and infrastructure, from scratch.

• Build the app on top of it: real time lactate display, readable mid session.

• Build the codebase and systems in a way that a growing software team can build on, not just you.

• Work with our CTO and sensor team. Understand what the hardware actually produces, and build for its imperfections.

Core Requirements

• A few years of experience designing system architecture, you've made the calls on how data, backend, and infrastructure fit together from early on.

• Experience with cloud infrastructure and data pipelines, ideally including time series, IoT, or continuous sensor data.

• Comfortable with mobile or cross platform development and BLE data handling specifically.

• You take initiative and solve problems without waiting to be told exactly what to do.

• Eligible to work in Denmark, on site at our office in Kongens Lyngby, Copenhagen, available to start as soon as possible.

Ideal Background

• Experience with wearables, or other data-sensitive consumer products, where privacy and data handling weren't an afterthought.

• Genuine interest in sport, physiology, or performance data.

You'll Thrive Here If

• You care about performance and want to build for people chasing it, from Olympic hopefuls to weekend athletes.

• You've felt what a bad app does to good data, and you don't want to be the one who ships that.

• You like to take ownership of your work and want to move fast.

• You like working with an ambitious team.

What We Offer

• Full time, paid position with equity warrants.

• Real architectural ownership: what you design now is what NDURE runs on for years.

• Direct access to the founding team and the decisions shaping the company.

• First engineer on the software team, which will grow fast around what you build.

• Starting date: As soon as possible.

If this sounds like the problem you want to spend the next few years solving, join us.
