Senior AI Engineer – Search & Recommendation – Patient Team (x/f/m)

Responsibilities

We are representing a confidential healthtech organization seeking a Senior AI Engineer - Search & Recommendation for their patient-facing platform in Paris.

In this role, you will design and build production search and recommendation systems that help millions of users across Europe find and access care. Your work will directly impact the quality, speed, and trustworthiness of the patient experience.

Your responsibilities include:

• Design and build production search and recommendation architecture, including full retrieval, ranking, and reranking pipelines using vector search, semantic retrieval, and LLM-based or managed rerankers
• Establish strong baselines with prompts, RAG, and model selection before implementing custom ML solutions
• Build evaluation and observability into every stage, with offline and online evaluation capabilities
• Set up data and event feedback loops that drive iteration and support deeper ML work
• Improve search relevance and ranking on patient-facing products, raising result quality
• Own production quality including latency, reliability, monitoring, and maintainability
• Partner with ML Engineers and collaborate with Product Managers and Software Engineers to define, build, and ship AI-powered features that deliver measurable value

What We're Looking For

You could be our next hire if you have:

• Production deployment experience: Ability to ship algorithms to production, ideally on AWS-based infrastructure
• Strong analytical mindset: Result-oriented with a user-first approach
• Significant experience as a Software or AI Engineer shipping search or recommendation systems to production
• Hands-on experience building end-to-end retrieval: Ranking and reranking pipelines, familiar with nDCG, MAP, Recall@k, and MRR metrics
• AI-engineering proficiency: Turning foundation models and off-the-shelf components into production systems including embeddings, vector search, semantic retrieval, RAG, and LLM-based or managed rerankers (e.g., Vertex AI)
• Architecture-first approach: You build the system, baselines, evals, and feedback loops with standard tooling before reaching for custom ML, and know when to partner with ML Engineers
• Evaluation and observability built into every stage: Offline and online evaluation, A/B testing, position-bias handling, and monitoring
• Production deployment capabilities: Ability to ship reliable, low-latency services with sub-second SLAs, with care for data quality and long-term maintainability

It would be fantastic if you also have:

• Experience at a B2C marketplace (e-commerce, hospitality, travel)
• Additional ML methodologies: Pattern mining, recommendation systems, experimentation, or causal inference
• Experience with search engines or information retrieval concepts
• Exposure to learning-to-rank or feature engineering
• Experience in healthcare or other regulated domains (GDPR/HDS)

Technical environment: Rails, TypeScript, Java, Python, Kotlin, Swift, React Native on a cloud-native platform

Location: Paris (Levallois area)

Employment type: Permanent, Full-time
