LLM Engineer (100 remote-friendly within Spain)

Area of Work

You will join our global Machine Learning and Data Science unit a core team of machine learning scientists (LLM ASR) engineers and an expanding group of country-specific linguists. Your work will be embedded in the ever-growing Noa product line used daily by doctors in Brazil Mexico Poland Italy Spain and Germany. mission is to broaden access to top-quality healthcare first by lifting administrative burdens from clinicians and soon by assuming selected medical tasks. Our flagship product is Noa Notes which records consultations transcribes the audio and produces a structured draft of the medical record. 

We operate cross-functionally moving ideas from prototypes to full-scale production with state-of-the-art ML frameworks and modern MLOps practices. We begin with rapid validation sprints where engineers work side by side with Product on early experiments then consolidate and scale proven capabilities standardizing validation methods engineering best practices tools and lifecycles.

Role

As an LLM Engineer in the Noa ML team you will support a product area within our Noa organisation to deliver end-to-end LLM capabilities. You will work alongside other machine learning professionals at various seniority levels and report directly to the Head of Machine Learning & Data Science.

Backed by a strong engineering culture we pair industry-leading LLM implementation rigor with pragmatic delivery making smart trade-offs to ship value quickly and iterate this role youll work with exceptional engineers and other LLM researchers on some of Docplanners most strategic initiatives leveraging foundation models to push the boundaries of AI in healthcare.

Our tech stack includes Python LangChain HuggingFace Transformers Vector Databases FastAPI among the others running on Kubernetes in AWS.

What you will be doing

• Work closely with cross-functional teams including scientists engineers and product stakeholders to deliver LLM-driven initiatives that directly contribute to business objectives.

• Design deploy and iterate over LLM services for text-based applications (and beyond) while proactively identifying and eliminating performance bottlenecks.

• Build small to medium-sized Python projects and collaborate with engineers on production code and deployments at scale.

• Assess platform engineering and LLMOps bottlenecks; research and design scalable prompt management strategies and recommend solutions that balance performance cost and reliability.

• Research architect and deploy LLM-powered information retrieval solutions (e.g. RAG) to deliver accurate results in complex multilingual product environments.

• Partner with the AI Platform team to refine LLMOps best practices evolve frameworks and establish efficient scalable workflows.
