Join us to build evidence-based, engaging health apps, for everyone

About Us:

We launched our first app to help users learn evidence-based mental health techniques just one month ago. In a randomized waitlist-controlled study (n = 176, Medical School Berlin), we were already able to demonstrate its effectiveness in improving mental health outcomes such as well-being and stress. The initial feedback from users has been overwhelmingly positive.

Next, we aim to build on this foundation by further enhancing our mental health app and developing additional programs in other health areas. In parallel, we’re working on the regulatory aspects and collaborating with health insurers to make our app accessible to as many people as possible. (+ Experimental Research Studies like audio only intervention, AI-Chat etc. )

Tasks

About the Role:

We’re looking for passionate people who want to build the future of evidence-based and engaging health apps.

You might be a Product Manager, Psychologist, Designer, Social Media, Medical Student, Marketing, Developer, Researcher — or bring a completely different perspective. What matters most is that you’ve shown you can take ownership of a topic, project, or product and drive it forward.

We want you to own a topic end-to-end — from defining the strategy to actually executing it, whether that means researching, designing, coding, or building something to create the best evidence-based engaging health apps.

Application:

• Download the Z38 Mental Health App from the App Store or Google Play and explore it a bit.
• Once you get a feel for our approach and like what you see, text us via the Link here “Apply here.” with some short information why you would be a good fit for Us and why you want to work on z38health (include also a link to your LinkedIn profile)
• We’ll reach out within a few days with a few short questions.
• Then we’ll schedule a chat to get to know each other and see if we’re a great fit to work together on the Z38 App

Requirements

We have no hard requirments but are looking especially for:

• What matters most is that you’ve shown you can take ownership of a topic, project, or product and drive it forward.

Benefits

We’re currently exploring different types of positions, but for now, we’re mainly looking to fill two positions in a one-year Fellowship Program starting February 1st, 2026. The program offers a basic stipend (+ Bonus) and the opportunity to work hands-on on our mission to build engaging, evidence-based mental health apps.
