## About the Role

* Degree or above in Physics, Data Science, Applied Mathematics, Engineering or a similar subject, or [2] years' relevant experience in data science or quantitative research, * Data analysis in Python (NumPy, SciPy, pandas, scikit-learn or similar)
 * Heavy, day-to-day use of AI tools in your technical work, such as coding assistants and LLMs, with the judgement to verify their outputs
 * Image or signal processing, ideally on data from scientific instruments
 * Statistics applied to measurement data: uncertainty, repeatability, noise and drift
 * Machine learning methods, and how to validate them properly
 * Clear, reproducible code and reports
 * Explaining results to technical and non-technical colleagues
 * Curious and adaptable, happy to work quickly and test ideas against the evidence

We'd love to see:

 * Atomic Force Microscopy or other nano-characterisation (SEM, FIB, profilometry), or semiconductor metrology
 * Physics-based modelling or simulation
 * Version control (Git) and C#, and experience building agentic or AI-assisted analysis workflows, 2nd stage: (2.5 hours) Face to face onsite evaluating technical, presentation and communication skills along with your ways of working and your opportunity to to know more about us

## Description

We are looking for an ambitious and adaptable Data Scientist to join our new Data Science team in the Technology department, reporting to the Data Science Lead and working closely with our Modelling Scientist. You will generate and curate data, develop and test new algorithms, and benchmark them against what the instrument can physically deliver. When a method proves itself, you will package it for the Data Analysis team in Engineering, who turn it into robust product software. You will work with real customer use cases and wafer data from Applications Development, and proof-of-concept data from R&D.

We are an AI-first team, so you will use AI tools every day, while checking carefully what they produce. If your passion is speed, evidence and finding out what the data can really tell you, we'd love to hear from you.

What you'll be doing

 * Generate synthetic data, and build and maintain the demo and performance data libraries
 * Analyse instrument data to quantify noise and limitations, and help establish the information limit, meaning what is physically extractable from the instrument
 * Develop and test new algorithms and analysis methods (for example PCA, percentile methods and machine learning) on real and synthetic data
 * Benchmark methods against the information limit: achievable performance, measurement uncertainty, gauge R&R and drift contributors
 * Write clean, reproducible prototype code with test data and expected performance, ready to hand over to Data Analysis, and build analysis tools used across the Technology department
 * Use AI tools every day to code, explore, analyse and report faster, verify what they produce, and present your results to the team, We will interview you: Monday to Friday UK Time 9am to 4.30pm and we'll be as flexible as we can with Global Scheduling
