AI Engineer at Materiom

Materiom · London, UK

Hybrid Full-time GBP 75,000
  • Competitive salary from £75K+ depending on experience
  • Performance-based annual bonus
  • 30 days’ paid annual leave plus UK bank holidays
  • Annual learning and mentorship budget

Materiom is an innovation platform for regenerative materials R&D, on a mission to accelerate the development of bio-based materials that replace petrochemical plastics. We are a team of around twelve people spanning materials science, AI/ML, software engineering, circular economy and design, transitioning toward commercial viability while staying true to our public-benefit focus.

The role

This mid-level role sits at the intersection of applied machine learning and applied AI: predictive modelling on scientific data alongside building LLM-powered tools. The work spans two main areas:

  • Predictive modelling – developing ML models that map bio-based formulation design spaces, and the MLOps infrastructure for active learning
  • LLMs and agentic systems – integrating our data and model intelligence into AI agents

Responsibilities include:

  • Design, build and deploy ML models that predict bio-based formulation properties
  • Develop and maintain data mining, model training and active learning pipelines
  • Build and improve LLM-powered tools and agentic systems
  • Deploy ML/AI tooling to partners and users to gather feedback
  • Run rigorous modelling experiments and iterate toward quality objectives
  • Contribute to LLMOps and MLOps practices, including versioning and monitoring
  • Communicate complex technical concepts to multidisciplinary teams
  • Collaborate closely with the tech team while staying aligned with product and scientific priorities

Who we are looking for

2-4 years of professional experience in data-driven or ML engineering, ideally in a startup environment.

  • Master’s degree in a technical field (Computer Science, AI or Machine Learning)
  • Strong ML fundamentals with a solid understanding of model mechanics
  • Hands-on experience with structured/tabular data and real-world model development
  • Practical LLM building experience – prompt engineering, RAG, tool use and agentic frameworks
  • Strong Python skills with good software engineering practices
  • Familiarity with a major cloud platform (e.g. GCP)
  • Excellent problem-solving and analytical skills
  • Comfortable operating independently in ambiguous environments

Nice to have:

  • Experience deploying ML/AI artifacts for user feedback collection
  • Active learning or closed-loop experimentation workflows
  • Scientific data familiarity (chemistry, materials science)
  • Open-source framework experience
  • Interest in bio-based materials or sustainability

Why apply

  • Competitive salary from £75K+ with performance-based annual bonus
  • 30 days’ paid annual leave plus UK bank holidays
  • Annual learning and mentorship budget
  • Flexible hybrid working with remote options and Bike2Work scheme
  • International company retreats and an interdisciplinary, collaborative culture
  • Meaningful work at the frontier of regenerative, sustainable materials
