Backend Engineer (Kotlin)

Permanent

Negotiable

Berlin

I’m working with a Series A startup bringing AI into healthcare to build tools that genuinely improve how clinicians and patients interact with technology.

They’re a high performing engineering team with a strong culture of trust, thoughtful engineering, and low ego. No unnecessary meetings, no rigid hierarchy, and no expectation of burnout – just smart people building meaningful products.

If you enjoy solving real problems with modern technology, this could be a great fit.

What You’ll Work On

As a Senior Backend Engineer, you’ll help design and scale the backend systems powering an AI assistant used in healthcare environments.

You’ll collaborate closely with product, AI/ML, and frontend teams while having real autonomy and ownership.

Your work will include:

* Building and evolving backend services using Kotlin
* Writing efficient, non-blocking code using Kotlin Coroutines
* Designing reliable, well-structured APIs
* Working alongside ML engineers to bring AI features safely into production
* Improving performance, scalability, and observability as the platform grows
* Making pragmatic engineering decisions focused on simplicity and maintainability

What They’re Looking For

You don’t need to tick every box, but strong candidates will have:

* Solid backend engineering experience with Kotlin
* Hands-on experience with Kotlin Coroutines
* Experience building APIs or distributed backend systems
* Good understanding of databases and data modelling
* A focus on code quality, testing, and maintainability
* Comfort working remotely with a high-trust team

If you’re interested in using AI to solve meaningful problems in healthcare, feel free to reach out or apply.
