Role
Who you are
- You own the Product, not just the Ticket: You think in solutions, not tasks, and build backend architectures that solve real-world patient needs
- You are an AI-Native Engineer: You’ve mastered LLMs and Multi-Agent setups as strategic tools to accelerate development and stay ahead of the curve
- You bridge the Stack: You are a Backend expert who naturally understands Mobile constraints, ensuring seamless performance from the API to the device
- The Backend Core: You are an expert in Ruby on Rails and TypeScript, with a track record of running these stacks in high-stakes production environments
- Infrastructure & Scale: You have a robust understanding of PostgreSQL and are comfortable navigating AWS (Cognito), Docker, and Kubernetes
- Quality & Testing: You have experience with end-to-end testing frameworks (like Cypress) and guide the team in implementing best practices for test coverage and code quality
- The Mobile Bridge: You understand the mobile ecosystem. Experience with React Native will help you design backend architectures that harmonize perfectly with the frontend
- Modern Delivery: You are a proponent of continuous delivery and highly experienced in Over-the-Air (OTA) updates, ensuring a seamless experience for our patients
- AI-Native Mindset: You already use LLMs as a force multiplier in your daily coding and have a clear vision for how autonomous agents can transform software development
- Collaborative Challenger & Communicator: You don’t just execute; you elevate. Driven by a proactive "can-do" attitude, you thrive on challenging the status quo to drive mutual growth. As a true team player, you bridge the gap between high-level tech and business value, translating complex concepts into clear, compelling narratives for non-technical stakeholders
What the job involves
- We are looking for a Senior Backend Engineer (all identities) to join our team in Berlin. It is an exciting time to work at Caspar because you will be the one designing how our patients will use the app in the future
- Architectural & Backend Engineering: You will design, build, and improve high-performance APIs and services that power the Caspar Health app, ensuring scalability, resilience, and operational excellence
- AI Frontier: We don’t just talk about AI; we build with it. You will design, build, and improve LLM-powered workflows and contribute to developing a multi-agent environment to enhance engineering productivity and efficiency
- Cross-Functional Collaboration: You will partner with Product, UX, DevOps, and Engineering teams to deliver robust solutions and contribute to technical discussions, architecture decisions, and engineering best practices
- Raising the Bar: You will champion best practices in code quality and test automation (e.g., Cypress)
Our take
The digital healthcare market is one of the fastest-growing on the planet, and is expected to be worth over $400 billion by 2027. With key drivers including increasing use of mobile platforms, rapidly changing healthcare infrastructure and government initiatives across the globe, this is a market blossoming with opportunity.
Caspar Health is looking to make the most of this. Founded in 2016, the platform enables recovering patients to access rehabilitation services on-demand, such as physiotherapy, sports therapy and even psychosomatic medicine. Setting out to solve the traditional problems with aftercare - things like specialist shortages and location constraints - Caspar Health looks like a highly disruptive prospect.
The company's impressive early metrics - including one bi-annual growth figure topping 300% - have garnered massive investor interest. Using funding won across multiple rounds, Caspar Health wants to expand its existing set of clinical partners, with a goal of supporting all rehabilitation clinics throughout Germany. In the future, its ambitions may go much further.
