About Materiom

Materiom's mission is to create a world where materials regenerate nature and support human health. We pursue it by building data and AI tools that help discover natural alternatives for packaging, textiles, and the built environment. We support innovators around the world to bring these new materials to market.

We're an interdisciplinary team bringing together materials engineering, computational materials science, AI/ML engineering, and business innovation. In 2026, we're at an inflection point: with advanced AI and a self-driving lab, we are accelerating the discovery of natural materials and supporting innovators across the sector.

The role

This is a high-impact role with the potential to apply leading AI/ML to one of the world's greatest challenges. We're looking for a mid-level AI Engineer to work at the intersection of applied ML and applied AI; someone equally comfortable developing predictive models on structured scientific data as they are with building LLM-powered tools and agentic workflows.

You'll work within our tech team to contribute across two primary workstreams:

  • Predictive modelling & representation learning: contribute to the development and operationalization of ML models that learn the high-dimensional, multi-objective, natural polymers design space.
  • Material discovery agentic systems: contribute to the development and evaluation of agentic systems for scientific discovery, interfacing with Materiom’s models, simulation capabilities, and internal and external self-driving labs.

What you'll do

ML modeling

  • Design, build, and deploy structure-property prediction ML models of bio-based formulations from experimental, in-silico and literature-mined data. In pursuit of a base model that generalizes across materials systems.
  • Run rigorous experiments to compare modelling approaches, interpret results clearly, and iterate toward quality goals.
  • Quantify how confident models are in their predictions, and use that to decide which experiments or simulations to run next.
  • Work with materials scientists to define new features and target properties, data standards and success criteria for each model.

Agents for materials discovery

  • Contribute to Materiom’s agentic stack for scientific discovery, ranging from hypothesis generation to closing the loop with Materiom’s SDL and simulation engine.
  • Build tool interfaces, such as MCP servers, that give scientists and agents structured access to internal and external resources such as Materiom’s databases, predictive models, simulation engine and lab instruments.
  • Track developments in AI for science and agentic research, and prototype promising methods against Materiom’s use cases.

MLOps

  • Develop, operate and maintain workflows for data extraction, model training & evaluation, and orchestration workflows against lab equipment/partners.
  • Contribute to LLMOps and MLOps best practices, including versioning, monitoring, evaluation, cost/quality optimisation.
  • Deploy ML/AI-driven tooling to project partners, pilot users and beyond in order to gather user feedback.

Internal & external-facing collaboration

  • Effectively communicate complex technical concepts and findings to multidisciplinary audiences.
  • Work closely within the tech team and stay closely attuned to product and scientific priorities, translating them into well-scoped technical work.

What we're looking for

You'll need:

  • Genuine excitement about the potential of transforming the materials sector through AI-enabled materials discovery of breakthrough bio-based alternatives.
  • Solid grounding in ML fundamentals: statistical learning, neural networks, optimisation, model selection and validation, uncertainty estimation, and working with small, noisy or imbalanced datasets.
  • Practical experience developing ML-powered systems end to end, from data curation, collection and preparation to model choice and hyperparameter tuning, to model deployment. You have experience with PyTorch, scikit-learn, MLFlow, etc.
  • Practical experience building LLM-based agents, improving them through metrics-driven evaluation, ideally including research loops where agents propose, run and evaluate experiments to optimise agent performance or to develop ML models. You have experience with e.g. PydanticAI, CrewAI, Google ADK etc.
  • Familiarity with at least one advanced deep learning technique such as geometric learning (equivariant GNNs), spatio-temporal techniques (SSMs, neural ODEs), world models (JEPA, latent dynamics models), language modeling (chemical and protein LMs), diffusion models, or physics-informed neural networks (PINNs).
  • Master’s degree in a technical field (e.g., Computer Science, Artificial Intelligence, Machine Learning), plus 2 to 4 years of professional experience in an AI start up environment.
  • Strong Python skills and good software engineering habits: version control, testing, reproducible pipelines.
  • Familiarity with a major cloud platform (e.g. GCP, AWS).
  • Experience working in an environment that translates well into a small startup setting. You have high agency & autonomy in an ambiguous environment. You thrive at shipping progress without needing everything defined upfront.

Useful but not required:

  • Proficiency in getting ML/AI-centric artefacts in front of users for obtaining real-world feedback.
  • Experience with active learning or closed-loop experimentation workflows.
  • Familiarity with scientific data from chemistry, materials science, or adjacent domains.
  • Experience with relevant open-source frameworks.
  • Background in or genuine curiosity about bio-based materials or sustainability.

What We Offer

Materiom is an impact-focused startup offering a supportive and flexible environment where you can drive the acceleration of net-positive materials using cutting-edge technology. Our benefits include

  • Competitive Salary: An annual salary range of £70K+, commensurate with your experience and expertise.
  • Annual Bonuses: Eligibility for performance-based bonuses to reward your contributions to the company’s success.
  • Generous Paid Time Off: 30 days of paid holiday per year for full-time positions (adjusted pro-rata for part-time positions), in addition to all UK bank holidays.
  • Learning & Mentorship Grants: An annual individual budget dedicated to developing your hard and soft skills.
  • Commuter Support: Access to a Bike2Work scheme to support sustainable travel.
  • Flexible Hybrid Working: A highly flexible scheme that includes weekly days at the office (London) and at home, as well as options for temporary remote work.
  • International Retreats: Regular company retreats, often held in international locations, to build connection and celebrate progress.
  • Collaborative team culture: Our culture is defined by deep, interdisciplinary collaboration, offering you the exciting opportunity to work at the intersection of materials science and AI to drive positive impact for people and the planet

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
