Are you ready to build the primary care platform of the future by becoming an integral part of a dynamic team? If you also believe in the positive transformative power of technology in bringing primary care to the next level - join us!

Responsibilities:

• Build and ship backend services as part of our microservice architecture, with AI agents and LLM-powered features as a core part of what you deliver
• Design and write MCP servers and tool interfaces that let agents reliably interact with our systems and APIs
• Develop agent harnesses, orchestration layers, and memory modules that give agents the context and state they need to act dependably
• Make deliberate design decisions about agent behavior
• Build evaluation frameworks and test harnesses to measure agent reliability, safety, and quality in a high-stakes healthcare context
• Integrate large language models into production with strong attention to latency, cost, and observability
• Raise the bar and drive technological innovations to keep us at the cutting edge
• Apply continuous integration and deployment principles
• Ensure code quality and maintainability by writing tests, doing code reviews, and refactoring

Requirements

• Proven track record of backend software development with Java/Kotlin and/or Python, minimum of 5 years
• Hands-on experience building LLM-powered applications, agents, or agentic workflows (tool use, function calling, multi-step orchestration)
• Familiarity with major LLM APIs and frameworks (eg Anthropic, OpenAI, or similar) and an understanding of how to design tooling, MCPs, and memory for agents
• Experience designing and running evals or test harnesses for non-deterministic systems
• Experience with Spring Framework and messaging brokers such as RabbitMQ
• Solid understanding of SQL databases and developing containerized applications
• Experience with Kubernetes and Terraform is a plus
• A pragmatic mindset for shipping reliable software - and reliable AI - in a regulated, high-stakes domain
• English working proficiency

Work Setup:

• Flat hierarchies and a collaborative working environment.
• Attractive compensation package.
• Option for remote work.

• Flexible working hours with a high degree of personal responsibility.
