Job Title: Machine Learning & Simulation Modelling Specialist

Location: Falmer, Brighton
Contract Type: Permanent
Salary: Circa £65,000 per annum depending on skills and experience
Team: Operational Planning & Improvement (Wastewater)
Reporting to: Technical Improvement Manager

Join Us to Shape the Future of Predictive Wastewater Intelligence

Are you passionate about using AI and machine learning to solve real-world environmental and operational challenges? Do you want to work on projects that directly reduce pollution, predict failures, and improve the performance of wastewater systems?

Southern Water is seeking a Machine Learning & Simulation Modelling Specialist to join our Operational Planning & Improvement (OP&I) team. In this high-impact role, you’ll develop predictive models, digital twins, and simulation tools to help forecast asset failures, optimise treatment processes, and drive smarter, data-led decision-making.

Working closely with engineers, ICA specialists, planners, and our central data team, you’ll help transform sparse and real-time data into actionable insight that supports field operations and enhances regulatory compliance.

What You’ll Be Doing

Build and deploy machine learning models to forecast pollution events and asset failures. Develop and apply digital twins and simulation models to evaluate optimisation strategies. Design data pipelines and integrate datasets from SCADA, telemetry, sensor networks, and operational systems. Convert model outputs into practical dashboards, alerts, and planning tools for engineers and field teams. Work cross-functionally to embed AI models into daily workflows and planning decisions. Use low-data ML techniques to extract insight from poorly instrumented or sparse datasets. Contribute to major improvement initiatives targeting compliance, resilience, and performance. Champion innovation, collaboration, and knowledge sharing across OP&I and beyond.

What We’re Looking For

Skills & Competencies

Practical experience applying machine learning and simulation modelling in an operational or industrial setting. Skilled communicator with the ability to explain complex technical ideas clearly to non-technical audiences. Highly collaborative and comfortable working across teams (engineering, ICA, digital, data). Confident in Python, SQL, and ML frameworks like scikit-learn, TensorFlow, or PyTorch. Strong problem-solving skills, attention to detail, and ability to work in agile, fast-paced environments. Able to manage time-series data and deliver scalable, robust ML models.

What You’ll Need

Essential Knowledge & Qualifications

Proven experience developing ML models for predictive maintenance, anomaly detection, or operational optimisation. Hands-on experience with digital twins or simulation modelling tools. Background in SCADA, telemetry, or sensor-based data processing. Degree (or equivalent experience) in a relevant field such as Data Science, Engineering, Environmental Modelling. Familiarity with cloud-based platforms like Azure, AWS, or GCP. Awareness of environmental regulations, permit compliance, and ethical AI principles.

Desirable

Experience working in the wastewater or utilities sector. Knowledge of modelling tools like SIMBA or BioWin. Understanding of data ethics, model transparency, and responsible AI use.

Why Join Southern Water?

Be part of a growing team at the heart of our digital transformation journey. Work on meaningful projects that protect the environment and improve service delivery. Collaborate with multidisciplinary teams and contribute to innovation in utility operations. Enjoy flexible working, training and development support, and opportunities for career growth.

How Many Machine Learning Tools Do You Need to Know to Get a Machine Learning Job?

Machine learning is one of the most exciting and rapidly growing areas of tech. But for job seekers it can also feel like a maze of tools, frameworks and platforms. One job advert wants TensorFlow and Keras. Another mentions PyTorch, scikit-learn and Spark. A third lists Mlflow, Docker, Kubernetes and more. With so many names out there, it’s easy to fall into the trap of thinking you must learn everything just to be competitive. Here’s the honest truth most machine learning hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool. They hire you because you can solve real problems with the tools you know. Tools are important — no doubt — but context, judgement and outcomes matter far more. So how many machine learning tools do you actually need to know to get a job? For most job seekers, the real number is far smaller than you think — and more logically grouped. This guide breaks down exactly what employers expect, which tools are core, which are role-specific, and how to structure your learning for real career results.

What Hiring Managers Look for First in Machine Learning Job Applications (UK Guide)

Whether you’re applying for machine learning engineer, applied scientist, research scientist, ML Ops or data scientist roles, hiring managers scan applications quickly — often making decisions before they’ve read beyond the top third of your CV. In the competitive UK market, it’s not enough to list skills. You must send clear signals of relevance, delivery, impact, reasoning and readiness for production — and do it within the first few lines of your CV or portfolio. This guide walks you through exactly what hiring managers look for first in machine learning applications, how they evaluate CVs and portfolios, and what you can do to improve your chances of getting shortlisted at every stage — from your CV and LinkedIn profile to your cover letter and project portfolio.
