Staff Backend Engineer (Kotlin)

What We Do
We believe in hospitals without administrative overhead. To make this vision a reality, we already take over the entire billing process for our hospital clients — resulting in higher revenues and improved liquidity for clinics.
We combine our AI-based, state-of-the-art software with the expertise of leading DRG coding professionals. For us, quality is never optional – it’s the standard.

Why We Need You
As a Staff Backend Engineer (Kotlin), you'll take technical ownership of our platform architecture. You ensure that our systems run reliably, efficiently, and at scale — and you’ll continuously improve them together with the team.
You’ll shape architecture, coach colleagues, and always keep in mind how tech delivers real value to our users.

Tech Stack
Backend: Kotlin, Java, Hibernate, GraphQL, REST, PostgreSQL
Infrastructure & DevOps: Kubernetes (EKS), AWS (S3, RDS, SQS, CloudWatch), Terraform
Observability: Prometheus, Grafana, Alerting
Event-driven: RabbitMQ, AWS SQS
Nice to have: React, Python, interest in AI tooling

Your Responsibilities

• Take full technical responsibility for our Kotlin-based backend services, ensuring stability, scalability, and performance
• Prioritize strategically, make architectural decisions, and guide the team through their implementation
• Analyze incidents and support escalations — pragmatically and solution-oriented
• Coach team members on architecture, coding standards, and Kubernetes best practices
• Own security controls in line with our ISO 27001 and BSI C5 certifications

What You Can Expect
Autonomy with impact: You’ll take ownership of our core architecture – your decisions will directly influence the product, the platform, and the team.
Tech that matters: Your work creates real impact in the healthcare sector – making life easier for DRG coders, doctors, and nurses.
Remote work with a personal touch: Work from anywhere in Germany – with home office equipment of your choice or a coworking space. And yes, we still value face-to-face: through regular offsites, coworking days, or just a spontaneous coffee nearby.
Growth without buzzwords: Deep-dive into architecture, explore new tools, discuss clean code, mentor others – we’ll give you space to evolve and contribute meaningfully.
A team that actually works: We care more about honest collaboration than ego. We celebrate clean architecture, not empty talk. And yes, we do occasionally toast a solved incident with a beer – remotely or in person.

A Typical Day at DAMEDIC
09:00 – Daily with the product team: feature priorities, tech updates, customer feedback
10:00 – Focus time: implement new GraphQL mutations for the patient data module – clean and efficient
12:00 – API sync with the frontend team for the new dashboard
14:00 – Mentoring a junior engineer: code review, Hibernate tuning, Kubernetes insights
16:00 – Architecture session for a new AI feature: plan data flow, define messaging patterns
17:30 – Update documentation, review specs, plan tomorrow’s tasks
At the end of the day, you’ve made a meaningful contribution – to the product, the team, and the users.

Your Profile
Extensive experience in backend development with Kotlin or Java, especially in distributed architectures

Hands-on experience with AWS (EKS, SQS, RDS, CloudWatch, etc.)
Clear communication skills and a product-oriented mindset
Self-organized, pragmatic, and reliable working style
German is a plus, but not required
