Vollständige Stellenbeschreibung

Hi! We are AMBOSS and we are looking for a Senior Backend Engineer who is passionate about robust system architecture but also eager and willing to dive into the frontend when needed. Join our team and shape the future of medical education with us!

About AMBOSS

AMBOSS is a dynamic learning and clinical decision support tool committed to empowering medical professionals globally to deliver optimal care. Since our inception in 2012, we've harnessed cutting-edge technology to transform the way physicians acquire and apply scientific knowledge. Each AMBOSSian is passionate about being the champion of clinicians today - this motivates and unites us each day towards success. And what does success look like? When a clinician or med student tells us, “AMBOSS makes practicing medicine easier and enjoyable. I love what I do, and a big part is because of AMBOSS.”

Want to learn more about our culture? Watch our video to explore what makes us unique.

Why can this position be exciting for you?

As a Senior Backend Engineer in the Shop Team, you will sit at the heart of our mission, building and scaling the gateway that allows medical students and clinicians around the world to access the AMBOSS platform. In this team, your backend architectural decisions have a direct, measurable impact on revenue and user discovery. Whether you are scaling high-availability payment services or prototyping a bold new hypothesis, you will be defining how the world buys AMBOSS.
While your primary expertise and core focus will be on the backend, you will also have the opportunity to expand your skill set and collaborate on our frontend application, bringing a willingness to learn and work across the full stack.

You will:

Ramp Up: Become a domain expert in AMBOSS's shop and payment architecture, from deep subscription logic to international tax compliance.
Build & Scale: Design, evolve, and maintain high-availability backend services handling global payment processing and complex financial transactions.
Own the Lifecycle: Manage backend discovery, technical design, deployment, monitoring, and database management at scale.
Collaborate & Learn: Build deep working relationships with Product, Design, and Finance stakeholders. Work closely with frontend engineers and proactively learn/contribute to our React-based customer-facing application when features require end-to-end implementation.
Ship Impact: Deliver end-to-end features and backend improvements from discovery to deployment, ensuring a localized, frictionless checkout experience for our global users.
Innovate with AI: Use tools like Cursor or Copilot and research how emerging technologies (LLMs, automation) can add genuine user value.

You Bring:

Go (Golang): Deep, senior-level backend fundamentals (concurrency patterns, performance tuning, robust API design, and error handling).
Frontend Willingness to Learn: A foundational understanding of modern JavaScript/TypeScript and web mechanics, paired with an open, enthusiastic mindset to learn, read, and write frontend code in React alongside our team.
API Design: Comprehensive experience building scalable, clean APIs with GraphQL and/or REST.
Architectural Intuition: The ability to deconstruct complex, monolithic codebases and design highly resilient, distributed data models at scale.
Ops & Observability: Hands-on experience with Docker, CI/CD pipelines, and cloud infrastructure (AWS/Kubernetes). You write comprehensive backend tests and aggressively monitor your own metrics and dashboards.
Product-Minded & Pragmatic: You care deeply about why we build, focusing on business value and user impact over technical complexity for its own sake. You know when to ship a quick proof-of-concept and when to invest in long-term stability.
AI-Native & Comfort with Ambiguity: You are excited by AI-assisted development and can make sound technical decisions even when requirements are still evolving.

Nice to Haves

Payment Systems Knowledge: Strong conceptual understanding or direct hands-on experience building, scaling, or maintaining payment flows and subscription infrastructure (e.g., Stripe, Adyen, Braintree).
PHP: Familiarity or previous engineering experience with PHP, as it helps navigate components of our ecosystem.
Exposure to Event-driven architectures, message queues (e.g., Kafka, RabbitMQ), or distributed tracing.
Previous work with LLM integration or AI-powered features.

Benefits:

Rest & Time Off (30 paid vacation days, AMBOSS holiday, personal purpose day and more)

Food & Office Comfort (Daily healthy breakfast & lunch by in-house chef in Berlin HQ, AMBOSS daycare, work remotely from other office spaces in Cologne, Sardinia, Cape Town)

Health, Fitness & Mobility (Urban Sports Club -M plan- , Fitbit Versa 3, Deutschland Ticket…)

Check out the full list of benefits below:

We believe that diversity is a powerful driver of innovation and progress. That’s why we are committed to fostering an inclusive, respectful, and supportive environment where everyone—regardless of gender, age, ethnic or cultural background, religion, disability, sexual orientation, gender identity—is valued and given equal opportunity to thrive. We warmly welcome people of all backgrounds to help us fulfil our mission: empowering all medical professionals to provide the best possible care

Even if you don’t meet every single point in the job description, we still encourage you to apply. We’d love to hear from you!
