Mid / Junior Level Hydrogeologist


The Yellow Sub Hydro team is seeking a Mid / Junior Level Hydrogeologist to support the superstar Hydrogeology team. Our ideal person has some existing experience in modelling (surface water or groundwater) and some experience of coding in Python. What they lack in experience, they more than make up for in attitude – we’re after a positive, can-do spirit. We’re a small team that’s growing fast, if you’re a good communicator and enjoy the dynamic, hands-on environment that comes with scaling up a company – you’ll fit right in!



We are fully committed to gender equality and flexible working and will consider requests for full or part-time working patterns with home based working to suit. A life-work balance (deliberately with ‘life’ first) is essential for a sustainable future. We are seeking a resourceful and self-motivated individual to work collaboratively as part of our team. 


  • BSc qualified (or higher) in Geology, Environmental Geoscience, Environmental Science or similar, or equivalent experience in practice.
  • 1+ years industry experience of geoenvironmental/geotechnical projects.



This is not a conventional business, and it follows that this is not a conventional job opportunity. There will be no neat little box for you to sit in (either physically or metaphorically). This role will be home/remote working in the UK with ideal geographies being Wales, Midlands and the Southwest or London and the Southeast. We are willing to consider applications from further afield so don't let your geography limit your horizons.



  • Provide technical support to the modelling team
  • Participate in conceptual model development, data analysis and numerical modelling activities
  • Knowledge of 2D and 3D groundwater flow and transport modelling software
  • Strong analytical skills
  • Some programming skills
  • Confident problem solver
  • Some GIS skills
  • Desire to learn



Why our crew likes working here:

  • B Corp status
  • Triple Bottom Line – People, planet and profit equitably weighed
  • 26 days leave + bank holidays
  • Make impact
  • Wellbeing prioritised
  • Team away days
  • Flexible working
  • Diversity and Inclusion Policies
  • Mental health days
  • Collaboration encouraged
  • Personal development
  • Strong sense of purpose
  • 1% company contribution to the planet

The future is bright, the future is Yellow…what colour is your future?
