About the role
Set a new pulse for healthcare!
We are looking for a Senior Software Engineer to join the DIAL team in the Phone Assistant domain.
Your mission will be to design, build, and scale the AI-powered features that transform how practitioners and patients connect over the phone — making care more accessible for patients and reducing administrative burden for health professionals. You will work in a feature team developing the Phone Assistant, Doctolib's solution that combines LLM reasoning, speech recognition, and real-time backend systems, launching first in Germany and expanding to France and Italy.
Working in the tech team at Doctolib means building innovative products and features to improve the daily lives of care teams and patients.
What you'll do
Your responsibilities include but are not limited to:
Build and operate backend services in Node.js/TypeScript (with Python exposure), designing for reliability, scalability, and real-time performance
Design, evaluate, and ship LLM-based features end-to-end: prompt engineering, tool calling, structured outputs, guardrails, and fallback strategies
Own AI feature quality: build evaluation datasets and scorers (e.g., in Braintrust), track regressions, and make evidence-based ship decisions before each release
Deploy and operate cloud-native services on Kubernetes across major cloud providers (AWS/Azure/GCP), and evolve CI/CD pipelines with GitHub Actions
Design data models and drive database migrations and performance tuning for real-time workloads ( PostgreSQL : connection pooling, indexing, query optimisation)
Maintain a high testing bar (unit, integration, e2e), debug distributed systems in production with strong observability, and contribute to pragmatic, secure architecture decisions
Who you are
Before you read on: if you don't have the exact profile described below, but you feel this job description matches your skill set, we still encourage you to apply.
You'll be a great fit if you:
Have 5+ years of backend engineering experience building scalable, resilient systems in Node.js/TypeScript (with some Python)
Have hands-on production experience building LLM-based features: prompting, tool calling, structured outputs, eval frameworks, and handling real-world failure modes
Have proven experience deploying and operating services on Kubernetes within at least one major cloud provider (AWS, Azure, or GCP), with solid CI/CD practices
Have a strong testing culture (unit/integration/e2e), sharp debugging skills for microservices and distributed systems, and a focus on code quality
Are fluent in English, with a collaborative mindset and the drive to own problems end-to-end — from design to production
It would be fantastic if you:
Have experience with speech pipelines (ASR, TTS, streaming audio) or voice agents
Are familiar with event-driven architectures and message brokers (Kafka, RabbitMQ, NATS, or Redis Streams), and have hands-on PostgreSQL experience (EXPLAIN/ANALYZE, indexing strategies, connection pooling)
Have an interest in telephony and real-time communication (SIP, RTP, WebRTC) — no prior experience needed, we will teach you
