Mind Gym

Senior Psychometrician

Join Mind Gym as they are looking for a Senior Psychometrician

Location: London, UK (with hybrid working) | full time

MindGym uses the latest behavioural science to transform the performance of companies and the lives of people who work in them. We’ve partnered with over half the FTSE100 and S&P100, equipping them with an all-important human advantage.

We’re growing rapidly and have a bold vision to redefine how companies and individuals flourish, and so disrupt the market for behavioural change.

MindGym was born around a kitchen table in 2000. Since those early chain-tea-drinking sessions, we’ve inspired and transformed the performance of over three million people. And we’ve published four books, including an international best-seller. We’ve left the kitchen table, but we’ve never lost our hunger.

The Job

The Product Innovation team is the brain of MindGym. Our science-packed POVs, our game changing live products, our behavioural science powered coaching app, and of course our exciting new diagnostics are all being developed here. This role is in the Measurement and Diagnostics team, a growing function within Product Innovation. This team is responsible for the development of an extensive new diagnostics proposition that will help our clients to personalise behaviour change and also measure the impact of our products.

As a key member of the Measurement & Diagnostics Team, the senior psychometrician will work closely with another psychometrician, two behavioural psychologists, and the Director of Behavioural Measurement to steer the development of our diagnostics for individuals and organisations. This is an R&D role by nature, but the role also requires collaboration with our product team to build the digital infrastructure for our diagnostics as well as supporting on client projects with data analysis and subject matter expertise.

Your key responsibilities

  • Support the development of existing organisational diagnostics (e.g. wellbeing, inclusion)
  • Drive the development of our individual diagnostics tools (personality/motivation), particularly more advanced features such as ipsative scoring formats and predictive analytics
  • Work with our digital product team/external partners to build the technical infrastructure delivering our diagnostics
  • Analyse client data in collaboration with other internal teams to provide meaningful insights

About you

  • Experience developing psychology-based diagnostics/assessments
  • Proficiency in R/RStudio
  • Proficient in a wide range of statistical methods such as regression techniques, dimensionality reduction, structural equation modelling, cluster analysis, item response theory, linear mixed-effects models etc.
  • Ability to create technical manuals and non-technical documentation for internal use as well as for clients
  • Being a critical thinker is crucial not only to analyse data but also to find the right solutions taking into account complex interdependencies between our products.
  • Being a good collaborator and communicator is key to success as we are working closely together in our team but also work with other teams across the business
  • Being decisive and making rational, well-informed decisions will make a difference developing our diagnostics as well as building confidence with stakeholders/clients
  • Being flexible and adapting to new situations easily is an absolute advantage as we are on an exciting but sometimes unpredictable journey
  • The ability to plan, organise and structure your own work will help you to work efficiently across multiple tasks and shifting priorities


  • Experience with applying item response theory models in ipsative assessments.
  • A track record of analysing assessment or survey data in the organisational context.
  • Experience working on a digital product in collaboration with a technology/product function.
  • Strong proficiency with a variety of visualisation techniques to display data in the most engaging and informative way
  • Understanding of classic machine algorithms such as knn, random forest etc
