Berlin, Berlin, Deutschland Sonia Solutions Vollzeit
Let me introduce...

With Sonia, doctors are successful doctors. We create and deploy AI-enhanced solutions that make doctors' lives easier, patients' care better, and healthcare systems more efficient. If you're an intrinsically motivated self-starter who values impactful work, join us in revolutionizing healthcare.

We're looking for several Python Software Engineers (all) (levels: mid to senior) to take ownership of critical backend components in our AI-driven products. You'll design and implement scalable architectures, mentor others, and ensure our systems are robust, reliable, and future-proof. Partnering closely with engineering and ML teams, you'll build APIs and services that enable real-time communication, data processing, and automation at scale—always with clean, maintainable, and high-performing code.

This role can be performed in a hybrid setup from our offices in Luxembourg or Berlin, or remotely from anywhere in Germany or Luxembourg.

This is what you'll own
  • Design, development, and maintenance of scalable backend services using Python 3 (async, type hinting).
  • Architect and implement RESTful APIs and real-time communication via WebSockets.
  • Drive technical discussions and decisions, shaping backend architecture and coding standards.
  • Debug and troubleshoot production issues, ensuring resilience, performance, and security.
  • Advance our CI/CD pipeline and containerized deployments (Docker).
  • Collaborate with ML engineers to integrate APIs and backend systems with AI/ML services.
  • Mentor and support other developers, fostering best practices in engineering, testing, and documentation.
  • Continuously identify opportunities for technical and process improvements.
You'll thrive in this role if you bring
  • 5+ years of professional experience in software development with Python 3.
  • Deep knowledge of asynchronous programming, type hinting, and software design principles.
  • Solid experience with web frameworks (FastAPI, Django, or Flask).
  • Proven track record of designing and scaling APIs and backend architectures.
  • Hands-on experience with real-time communication (WebSockets, Socket.IO, FastAPI WebSockets).
  • Experience with containerization (Docker) and CI/CD systems.
  • Strong debugging and testing skills in production environments.
  • Expertise with version control (Git, GitLab, Bitbucket).
  • Strong communicator with experience mentoring peers and leading projects.
Nice-to-Haves
  • Experience working with LLMs (routing, parsing, error handling, guardrails).
  • Knowledge of message brokers (RabbitMQ, Kafka, Redis Pub/Sub).
  • Exposure to NoSQL databases (Redis).
  • Familiarity with Kubernetes or DevOps practices.
  • Contributions to open-source projects.
Why you'll love working with us
  • Full ownership of impactful backend components in a fast-growing AI environment.
  • A collaborative team that values curiosity, learning, and pragmatic problem-solving.
  • Flexible working arrangements (remote or hybrid).
  • Competitive salary depending on experience.
  • The chance to work on products that directly shape the future of healthcare.
