Are you looking for a role where you can progress your career and improve the environment? If so, we have an amazing opportunity for a Senior Wastewater Data Scientist to join our Wastewater Strategy team!


What you’ll do

This is a fantastic opportunity to join Wessex Water at a time of unprecedented change, with the potential for you to make a huge difference within your role. Our investment plan proposes a doubling of investment over the next five years, and a large proportion of this is in wastewater. As a Senior Wastewater Data Scientist, you will be pivotal in shaping the scale of our investment in the future, including the evidence that will be used as part of our wastewater and environmental programmes in AMP9. Consequently, you will have a huge variety of responsibilities and the ability to significantly influence all levels of the business plan and in turn the future of the water industry. You’ll need to be able to switch between the big picture and details quickly. This will include working with your colleagues to ensure we have the data we need to evidence our long‑term strategies, such as our Drainage and Wastewater Management Plan (DWMP), Water Industry National Environment Programme (WINEP) and Long‑Term Delivery Strategy (LTDS). Depending on your experience, this may include developing tools in Python or R to support decision‑making. It would also be beneficial if you were able to help upskill the team to improve the ways we work.


What you’ll need

Within the team, you will be working alongside a variety of technically skilled people and liaising more broadly within and outside of the business. You’ll need to be technically skilled but also question usual processes to ensure we’re using the best data available to provide customers with the assurance that we are providing the best solutions for the environment. This role will suit someone who has a solid understanding of IT systems/software and can explain the importance of high‑quality data within this context.



  • degree qualified or equivalent, possibly with chartered engineer or equivalent status
  • excellent oral and written communication skills
  • personal skills that enable effective working with people at all levels
  • experience in asset management and the role of data science in its application
  • programming experience, such as in R, Python, and/or Matlab.
  • the ability to develop, follow, and maintain procedures that ensure the accurate maintenance of technical workflows.

While it would be beneficial, we don't expect you to be an expert in wastewater or the regulatory frameworks that are specific to the water sector! We’re looking for a data scientist who is enthusiastic and wants to help make a real difference to the way we plan to improve the environment.


What you’ll receive

  • A combined pension contribution of up to 20%.
  • Career progression and professional development opportunities.
  • 25 days’ holiday rising to 28 with length of service.
  • The opportunity to sell up to five days of holiday every year.
  • The opportunity to buy up to ten days of holiday each year (subject to conditions).
  • A healthcare package that allows you to claim back healthcare costs.
  • Life assurance of up to eight times your salary.
  • The opportunity to lease a new electric car through salary sacrifice (subject to conditions).
  • Cashback and discounts from more than 3,000 retailers.
  • One paid volunteering day each year.
  • Enhanced family leave and pay arrangements.
  • Access to an interactive health and wellbeing platform.
  • Support from trained mental health first aiders.
  • A £1,000 referral fee if you recommend someone who is successfully recruited by us.

Who we are

  • YTL UK is part of the international YTL Group based in Kuala Lumpur. The UK companies include:
  • Wessex Water – one of the top‑performing water and sewerage companies in England and Wales, serving 2.9 million people across the South West

  • YTL Arena – the development and operation of an entertainment complex that includes a 20,000 capacity arena, conferencing and exhibition space
  • plus a number of other retail, environmental and specialist businesses.

AI Jobs for Career Switchers in Their 30s, 40s & 50s (UK Reality Check)

Changing career into artificial intelligence in your 30s, 40s or 50s is no longer unusual in the UK. It is happening quietly every day across fintech, healthcare, retail, manufacturing, government & professional services. But it is also surrounded by hype, fear & misinformation. This article is a realistic, UK-specific guide for career switchers who want the truth about AI jobs: what roles genuinely exist, what skills employers actually hire for, how long retraining really takes & whether age is a barrier (spoiler: not in the way people think). If you are considering a move into AI but want facts rather than Silicon Valley fantasy, this is for you.

How to Write an AI Job Ad That Attracts the Right People

Artificial intelligence is now embedded across almost every sector of the UK economy. From fintech and healthcare to retail, defence and climate tech, organisations are competing for AI talent at an unprecedented pace. Yet despite the volume of AI job adverts online, many employers struggle to attract the right candidates. Roles are flooded with unsuitable applications, while highly capable AI professionals scroll past adverts that feel vague, inflated or disconnected from reality. In most cases, the issue isn’t a shortage of AI talent — it’s the quality of the job advert. Writing an effective AI job ad requires more care than traditional tech hiring. AI professionals are analytical, sceptical of hype and highly selective about where they apply. A poorly written advert doesn’t just fail to convert — it actively damages your credibility. This guide explains how to write an AI job ad that attracts the right people, filters out mismatches and positions your organisation as a serious employer in the AI space.

Maths for AI Jobs: The Only Topics You Actually Need (& How to Learn Them)

If you are a software engineer, data scientist or analyst looking to move into AI or you are a UK undergraduate or postgraduate in computer science, maths, engineering or a related subject applying for AI roles, the maths can feel like the biggest barrier. Job descriptions say “strong maths” or “solid fundamentals” but rarely spell out what that means day to day. The good news is you do not need a full maths degree worth of theory to start applying. For most UK roles like Machine Learning Engineer, AI Engineer, Data Scientist, Applied Scientist, NLP Engineer or Computer Vision Engineer, the maths you actually use again & again is concentrated in a handful of topics: Linear algebra essentials Probability & statistics for uncertainty & evaluation Calculus essentials for gradients & backprop Optimisation basics for training & tuning A small amount of discrete maths for practical reasoning This guide turns vague requirements into a clear checklist, a 6-week learning plan & portfolio projects that prove you can translate maths into working code.
