Job Title: Founding ML Engineer

Salary: £95K + Equity

Company Description: Klaris - NHS-backed AI platform transforming MedTech compliance

Job Description:
As the first ML hire, you will build the foundational data and MLOps flywheel for a safety-critical MedTech platform. You'll move beyond wrappers to develop custom algorithms and agentic RAG workflows that automate complex regulatory documentation. This is a high-impact, 0-to-1 role helping lifesaving medical devices reach patients faster through sophisticated automation.

Location: London, UK

Why this role is remarkable:

• Founding-level impact: You aren't just joining a company; you are architecting the technical culture and ML strategy from the ground up alongside a PhD CTO.

• Strong backing and traction: Supported by an NHS-affiliated VC, Antler, and Vento Ventures, Klaris already has pilot programs converting into paid enterprise customers.

• Mission-driven innovation: Your work directly accelerates the deployment of lifesaving medical technologies by solving the massive, manual bottleneck of regulatory compliance.

What you will do:

• Architect and scale production-grade MLOps infrastructure including CI/CD pipelines, monitoring, and model versioning using tools like MLflow or Weights & Biases.

• Develop and productionize advanced LLM solutions, including agentic workflows, RAG pipelines, and knowledge graphs to process complex regulatory documents.

• Lead the end-to-end data strategy, from building ETL pipelines and OCR tasks to fine-tuning models for safety-critical healthcare applications.

The ideal candidate:

• 4+ years of proven experience in MLOps and NLP, with a track record of turning experimental algorithms into robust, scalable software products.

• Deep technical proficiency in the Python ecosystem, specifically with FastAPI, Pydantic, vector databases, and containerization tools like Docker or Kubernetes.

• Founding team DNA: A high-agency builder who thrives in ambiguity and can make independent architectural decisions without needing established structure.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
