Company Description

Work with Us. Change the World.

At AECOM, we're delivering a better world. Whether improving your commute, keeping the lights on, providing access to clean water, or transforming skylines, our work helps people and communities thrive. We are the world's trusted infrastructure consulting firm, partnering with clients to solve the world's most complex challenges and build legacies for future generations.

There has never been a better time to be at AECOM. With accelerating infrastructure investment worldwide, our services are in great demand. We invite you to bring your bold ideas and big dreams and become part of a global team of over 50,000 planners, designers, engineers, scientists, digital innovators, program and construction managers and other professionals delivering projects that create a positive and tangible impact around the world.

We're one global team driven by our common purpose to deliver a better world. Join us.

Key responsibilities

• Lead and personally deliver water distribution model build, calibration, verification and maintenance projects, from asset audit through to final calibrated and peaked model submission.
• Own the full technical workflow: field test planning, data cleansing, demand analysis, total head graphs, flow and reservoir balances, flow, pressure and dynamic calibration, model peaking and scenario development.
• Undertake network capacity, growth and development impact assessments, zonal analysis, DMA and pressure managed area design, and level-of-service assessment against client criteria.
• Develop and appraise engineering options - pipe upsizing, rezoning, new transmission mains, storage, booster and pump upgrades, pressure control - and make evidence-based recommendations to clients.
• Undertake fire flow and firefighting supply assessments in line with the applicable national code.
• Lead rehabilitation, mains flushing and asset renewal studies as these services are introduced, including validating continuity of supply to downstream customers during works.

Team leadership

• Act as line manager for the Philippines water supply modelling team, including objective setting, performance review and progression recommendations. Final approval on progression and reward sits with the Discipline Lead.
• Set and maintain the technical standard for the team, and act as the senior technical authority on modelling method and engineering judgement.
• Allocate work across the team against programme, capability and development need, and manage capacity across concurrent commissions.
• Provide technical direction, coaching and structured development to Senior Engineers, Engineers and graduate modellers, and support the defined progression framework from routine assessment work into independent modelling workstreams.
• Support recruitment: technical assessment of candidates, interview panels, onboarding and technical induction as the team scales.
• Establish standard workflows, checklists, model user manuals and technical documentation for the team.

Quality, assurance and technical governance

• Act as internal technical checker, applying client QA/QC specifications and modelling standards before any deliverable leaves the team.
• Hold delegated technical sign-off for the Philippines team's deliverables within the agreed scope, escalating scope, criteria or commercial changes to the Discipline Lead.
• Operate the delegated-authority framework for the team's assessment work, including competency sign-off for Engineers and second-party checking of non-standard cases.
• Identify and report data gaps, GIS anomalies and model confidence limitations, and document assumptions and engineering judgement transparently.
• Support external project audits and maintain project records to audit and governance standards.

Client and project

• Act as the primary technical point of contact between the Philippines team and the lead offices in the United Kingdom, Ireland, Australia and New Zealand.
• Attend client progress calls, technical workshops and review meetings, and present modelling findings and proposed solutions directly to client engineers and asset planners.
• Manage project programme, budget, resourcing and deliverable control across concurrent modelling commissions.

Qualifications

• Typically 10 or more years of experience in water supply or water distribution network hydraulic modelling.
• Experience delivering water utility projects within one or more international markets. Exposure to the United Kingdom, Ireland, Australia, or New Zealand water sectors is preferred but not essential. Candidates with strong technical leadership and transferable experience from comparable water, utility, or infrastructure environments will also be considered.
• Demonstrable hands-on delivery of full model build and calibration lifecycles for potable water distribution networks - not model running or data support alone.
• Strong hydraulic fundamentals: headloss and pressure performance, pump and system curve behaviour, storage and reservoir balance, calibration logic, and the ability to judge whether a model is fit for the decision being asked of it.
• Proven competence in a recognised network modelling platform, evidenced by delivered projects.
• Experience acting as an internal checker or technical reviewer against a formal QA/QC specification.
• Experience leading a delivery team - allocating work, developing engineers, coordinating with a remote lead office, and managing programme, budget and resource.
• Direct client-facing experience: technical workshops, progress meetings, presentation of findings and handling of technical queries.
• Strong technical writing - asset audit reports, technical memoranda, model user manuals and option appraisals.
• Bachelor's degree in Civil, Environmental & Sanitary or Water Resources Engineering.

Must be amenable to work in a fixed night shift schedule and 3 days onsite per week.

Desirable experience

• Prior use of InfoWorks WS Pro or Synergi Water, which are the platforms most used across our current client base.
• Familiarity with water utility standards and processes from the United Kingdom, Ireland, Australia, or New Zealand, although this is not mandatory.
• Master's degree in Environmental Engineering, Water Resources or Hydraulics.
• Chartered or working towards chartership or registration (PICE, MICE, CIWEM / C.WEM or equivalent).
• Exposure to wastewater and urban drainage modelling
