Senior Software Engineer – Node.js/TypeScript (x/f/m)

Responsibilities

We are representing a confidential healthtech organization seeking a Senior Software Engineer - Node.js/TypeScript to join their AI-powered communications platform team in Berlin. Your mission will be to design, build, and scale intelligent features that transform patient-practitioner interactions through real-time backend systems combining LLM reasoning and speech recognition technology.

Your responsibilities include:

• 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 including prompt engineering, tool calling, structured outputs, guardrails, and fallback strategies
• Own AI feature quality by building evaluation datasets and scorers, tracking regressions, and making evidence-based release decisions
• 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 in PostgreSQL (connection pooling, indexing, query optimization)
• Maintain high testing standards (unit, integration, e2e), debug distributed systems in production with strong observability, and contribute to pragmatic, secure architecture decisions

What We're Looking For

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 exposure
• Hands-on production experience building LLM-based features including prompting, tool calling, structured outputs, evaluation frameworks, and handling real-world failure modes
• Proven experience deploying and operating services on Kubernetes within at least one major cloud provider (AWS, Azure, or GCP) with solid CI/CD practices
• Strong testing culture (unit/integration/e2e), sharp debugging skills for microservices and distributed systems, and focus on code quality
• Fluency in English with a collaborative mindset and drive to own problems end-to-end from design to production

Bonus qualifications:

• Experience with speech pipelines (ASR, TTS, streaming audio) or voice agents
• Familiarity with event-driven architectures and message brokers (Kafka, RabbitMQ, NATS, or Redis Streams)
• Hands-on PostgreSQL experience (EXPLAIN/ANALYZE, indexing strategies, connection pooling)
• Interest in telephony and real-time communication (SIP, RTP, WebRTC)

Position details: Permanent, full-time role in Berlin with hybrid work setup (up to 2 remote days per week). Tech stack includes Node.js/TypeScript, Python, Kubernetes, AWS/Azure/GCP, and PostgreSQL.
