About the role

Senior ML Engineer focused on Applied AI, MLOps, and backend/platform engineering to productionise and modernise an AI platform, including NLP/generative AI capabilities, observability, and safe deployment.

Responsibilities

  • Refactor, modernise and productionise existing ML models and Applied AI capabilities, including NLP and generative AI solutions.
  • Build new ML components and re-engineer existing models into standardised, production-ready modular components.
  • Develop production ML applications and supporting services primarily using Python.
  • Build and maintain reliable ML pipelines covering model integration, evaluation, deployment and operation.
  • Engineer resilient ML workflows with appropriate retry logic, error handling and repeatable execution.
  • Design and automate model evaluation pipelines using golden datasets and appropriate quality and performance thresholds.
  • Evaluate different types of models using metrics appropriate to their outputs, including generative AI, classification and other ML use cases.
  • Implement appropriate guardrails and evaluation mechanisms to assess grounding, hallucinations and quality of generative AI outputs.
  • Apply Applied AI techniques, including RAG, where appropriate to the ML capabilities being developed.
  • Design mechanisms for model, prompt and input-data provenance to support auditability and reproducibility.
  • Build infrastructure supporting shadow testing, A/B testing, fallback strategies and kill switches for safe ML deployment.
  • Support the labelling, curation and ongoing development of golden datasets used for model evaluation.
  • Build structured human-in-the-loop feedback pipelines to capture reviews and corrections and improve ML datasets.
  • Integrate third-party AI APIs and build appropriate adapter/API interfaces.
  • Implement observability and telemetry covering model behaviour, errors, compute costs, token usage and latency.
  • Contribute backend engineering capability required to integrate ML components reliably into the wider application.
  • Support both batch and real-time ML workloads as the platform develops.

Qualifications

  • 6+ years of professional AI/Machine Learning experience, with genuine production experience.
  • 5+ years of professional MLOps experience.
  • At least 2+ years of real Applied AI experience, working with AI/ML capabilities beyond experimentation or personal projects.
