Advance TRS is representing a specialist water consultancy that is looking to appoint Intermediate, Senior and Principal Wastewater Network Modellers to strengthen its UK modelling team.

This is an opportunity to join a technically focused business working on a range of challenging wastewater modelling projects, with a strong emphasis on technical quality, innovation and developing more efficient approaches to hydraulic modelling.

The successful candidates will work alongside experienced modelling specialists and have the opportunity to contribute to a variety of wastewater projects, while benefiting from access to wider international expertise and best practice.

The business is particularly interested in individuals with strong hands-on InfoWorks ICM experience who are looking to develop their technical expertise and progress their careers within a specialist modelling environment.

Responsibilities will vary depending on experience and seniority, but may include:

• Building, calibrating, validating and maintaining wastewater network models using InfoWorks ICM.
• Undertaking model verification and historical validation.
• Using modelling outputs to understand network performance and identify risks.
• Supporting root cause analysis and solution development.
• Developing and assessing practical, cost-effective and buildable solutions for wastewater networks.
• Providing technical input into project delivery and supporting multidisciplinary teams.
• Reviewing and quality-checking modelling outputs, appropriate to level of experience.
• Working with clients and project stakeholders to understand requirements and communicate modelling outcomes.
• Supporting and, at more senior levels, leading technical discussions with clients and project teams.
• Providing guidance, coaching and mentoring to less experienced colleagues where appropriate.
• Contributing to the development and improvement of modelling processes, specifications and best practice.
• Supporting innovation and the adoption of new technologies, automation and digital approaches within wastewater modelling.
• Managing technical and project delivery risks at the appropriate level of responsibility.
• Developing TOTEX-focused solutions that consider cost, risk, performance and operational requirements.

The team is involved in a broad range of wastewater network modelling activities, with opportunities to develop experience across areas including:

• Wastewater network model build and verification.
• Hydraulic modelling and root cause analysis.
• Solution development and optioneering.
• Network performance and capacity assessments.
• Water quality modelling.
• 2D modelling.
• Real-time modelling.
• Model auditing and assurance.
• Digital transformation and modelling automation.
• Development of innovative modelling tools and processes.

The successful candidates will have the opportunity to develop specialist modelling expertise rather than simply undertaking routine modelling work.

The client would consider candidates with approximately 3-5 years' relevant wastewater network modelling experience, depending on their technical capability and experience.

Candidates should have:

• Hands-on experience in wastewater network modelling using InfoWorks ICM.
• Experience of model building and verification.
• Exposure to calibration, validation, root cause analysis and/or solution development.
• A good understanding of hydraulic modelling principles.
• Strong analytical and data interrogation skills.
• Good written and verbal communication skills.
• A relevant degree or equivalent professional experience.

The client is particularly interested in candidates who are keen to continue developing their technical expertise and progress towards more senior modelling responsibilities.

Indicative salary: £40,000-£47,000.

The business is ideally looking for candidates with 5+ years' relevant wastewater network modelling experience, although the level of responsibility will be matched to individual capability.

Candidates should have:

• Strong hands-on experience in wastewater network modelling using InfoWorks ICM.
• Demonstrable experience of model building, verification, calibration and validation.
• Experience using models for root cause analysis and solution development.
• A strong understanding of hydraulic modelling and practical option development.
• Experience working with project teams and stakeholders to deliver modelling outputs.
• Good data interrogation and analytical skills, ideally including advanced Excel.
• Strong written and verbal communication skills.
• Experience supporting or mentoring junior colleagues would be advantageous.
• A relevant degree or equivalent professional experience.

Chartership is desirable but not essential for the Senior position.

Indicative salary: £47,000-£60,000, subject to Chartership and years of experience

For Principal-level appointments, the business is looking for candidates with 10+ years' relevant wastewater network modelling experience, including substantial responsibility for technical delivery and review.

In addition to the above, Principal candidates should demonstrate:

• Advanced technical expertise in InfoWorks ICM.
• A strong track record of technical leadership and quality assurance.
• Experience mentoring and developing modelling teams.
• The ability to lead technical discussions with clients and senior stakeholders.
• Experience managing technical and project delivery risks.
• A track record of improving modelling processes, methodologies and team capability.
• Experience with scripting, automation or digital modelling approaches would be advantageous.
• The ability to contribute to business development and support the growth of the modelling team.

Chartered professional status is required for the Principal position.

Indicative salary: £60,000-£75,000.

The business is committed to providing a clear career progression framework, with opportunities to develop both technical and leadership capabilities.

There is scope for individuals to broaden their expertise into specialist areas including optimisation, automation, water quality modelling, 2D modelling, real-time modelling and digital transformation.

The primary preference is for candidates based in London and the South East, with the Anglian region also being of interest.

The roles operate on a hybrid basis, with an expectation of approximately 2-3 days per week in the office. Fully remote working will also be considered for Senior / Principal grades.

• Join a specialist wastewater modelling team where hydraulic modelling is a core area of expertise.
• Work alongside experienced modelling specialists.
• Gain exposure to technically challenging wastewater projects.
• Develop specialist skills beyond traditional hydraulic modelling.
• Access wider international expertise and industry best practice.
• Opportunities to work with innovative digital and modelling technologies.
• Clear opportunities for career progression.
• Develop technical leadership and mentoring experience as your career progresses.
• Contribute to the continued growth and development of the UK modelling team.

Advance TRS is interested in speaking with wastewater network modellers at Intermediate, Senior and Principal level who are looking for their next career opportunity.
