Materials Knowledge Architect

CuspAI, London, UK +3

The role

Due to rapid company growth and expanding external data partnerships, we are seeking a Materials Knowledge Architect to join our Data team and lead the design of our scientific data representations, schemas, and ingestion pipelines.

What you will do

This is an exciting opportunity to join the data team at CuspAI, working closely with world-leading AI experts and materials science researchers to design the data models and ingestion pipelines that turn heterogeneous external data into actionable data assets. Much of the data that powers our models arrives in different formats, schemas and standards. As a Materials Knowledge Architect you will own how that data is represented, modelled and brought into CuspAI, and be foundational in ensuring its quality at scale so it can fuel the discovery of the next generation of materials.

What you need

Proven experience designing data models and schemas for complex scientific or technical domains, and curating high-quality data assets from them.
Demonstrable experience ingesting, integrating and harmonising data from multiple external sources or partners, each with differing formats, schemas and quality levels.
PhD in Chemistry, Physics, Materials Science, Computational Chemistry or a related discipline, or equivalent experience in scientific research.
Expert in data representation, ontologies, data modelling and the curation of high-quality, interoperable data assets.
Experience working with a broad range of data types used in materials discovery — especially experimental and characterization data (e.g. synthesis parameters and processing conditions, XRD patterns, spectroscopy, adsorption isotherms, device measurements) alongside computed properties (e.g. DFT-derived formation energies, band gaps) — and mapping them across heterogeneous sources.
Deep knowledge of materials and chemical data sources spanning both experimental and computational domains (e.g. ICSD, the Cambridge Structural Database, NOMAD, Materials Project), and of the practical challenges of harmonizing lab-generated data — instrument outputs, ELN/LIMS records, unit conventions, provenance — into interoperable, ML-ready assets.
Working knowledge of Python and SQL with experience building data pipelines for experimental and computational data, including schema/data-model design (e.g. Pydantic, JSON Schema) and familiarity with materials and data science toolkits (e.g. pymatgen, ASE, Pandas/Polars).
Firsthand experience with how experimental data is actually produced — lab workflows, instrument quirks, incomplete metadata — and pragmatic strategies for modeling it faithfully rather than forcing it into idealized schemas.
Strong communicator and a proven collaborator, comfortable working directly with external partners as well as multidisciplinary chemistry/physics/materials and product/engineering teams.
