About the role

  • Own and ship ML in production: take ideas from R&D to robust, maintainable deployments – often onto edge or embedded hardware.
  • End-to-end ownership: Lead the full lifecycle, data collection/curation, feature engineering, model training, evaluation, deployment, monitoring, and iteration.
  • Technical leadership: set direction, guide design/architecture, perform reviews, mentor teammates, and raise the engineering bar. You are a multiplier for the team’s capability.
  • MLOps/LLMOps: CI/CD for models, containerisation/orchestration, experiment tracking and registry, model evaluation pipelines, safety guardrails, canaries, and performance monitoring.
  • Cross-team collaboration: partner with software, systems, and product colleagues; simplify complex topics for other disciplines and customers; champion AI and data.
  • Data foundations: establish pragmatic data pipelines (batch/stream) that make curation, provenance, and reproducibility first-class.

Requirements

  • Proven delivery: experience leading technical work that delivered measurable impact in production, especially on edge, embedded, or mission-critical systems. You’ve made decisions that mattered and lived with the outcomes.
  • Deep domain expertise: mastery in at least one major area of ML (e.g. optimisation, computer vision, sequence modelling, LLMs, probabilistic methods), with the ability to apply that depth to real production constraints.
  • ML & maths depth: strong grounding in ML/DL (optimisation, generalisation, probability, model architecture) and the ability to reason about these trade-offs in production.
  • Software development: excellent Python skills; experience with low-level languages like Rust is desirable.
  • Interpersonal skills: strong communicator who can mentor, influence, and bridge technical and non-technical audiences.
  • Education: MSc or equivalent experience required.
  • Builder mindset: bias to action, ownership over outcomes, and comfort working through ambiguity.
  • Desirable:
  • LLMs & agentic systems: practical experience with prompt optimisation, retrieval/RAG, evaluation, and tool orchestration; aware of latency, cost, and reliability trade-offs.
  • MLOps excellence: reproducible pipelines, model versioning, CI/CD, observability, and automated evaluation.
  • Data engineering: proficiency with Databricks, Apache Spark, Delta Lake, MLflow, and SQL; experience integrating datasets and maintaining data quality.
  • Education: PhD in AI/ML/CS or related field.
