Quantitative Modeller — Energy Advisory

Turn complex models into commercial clarity

AECOM's Energy Advisory practice uses quantitative and techno-economic modelling to underpin the advice we give clients on energy transition, market design, investment and policy decisions. As our practice grows, we're looking for a Quantitative Modeller who can work hands-on across a range of modelling approaches from established energy market and dispatch tools through to bespoke, purpose-built models and translate that analysis into commercially grounded advice for clients.

This is a client-facing role working closely with a senior advisory team. You'll need to be comfortable working independently, engaging directly with clients, and always connecting your modelling outputs back to the commercial question at hand. We're open to a wide range of experience above our 5-year minimum for a more senior candidate, there's genuine scope to grow into a technical leadership role within the team over time.

What you'll be doing

• Building, running and interrogating quantitative models techno-economic, energy market and dispatch modelling, multi-sectoral modelling, or other bespoke analytical models with the judgement to choose the right approach for the question at hand

• Framing modelling exercises around the client's actual decision or advisory question, translating technical outputs into clear commercial insight and recommendations

• Working independently on modelling tasks with minimal oversight, while knowing when to flag assumptions, limitations or emerging findings to senior team members and clients

• Presenting technical analysis to non-technical audiences and defending modelling assumptions under scrutiny, with strong written communication to translate methods and findings into clear reports and deliverables

• Applying your quantitative and problem-structuring skills beyond energy where relevant the underlying capability matters as much as sector-specific tools

• Contributing to, or leading, broader advisory engagements beyond modelling bringing analytical rigour to non-modelling workstreams as needed

• For more experienced candidates: leading and developing modelling capability mentoring junior modellers, setting technical standards, and shaping how modelling is positioned within broader advisory engagements

What you'll bring

• Minimum 5 years' work experience, including at least 3 years in a quantitative modelling context we welcome candidates well above this minimum, including those ready for technical leadership

• Experience in quantitative or techno-economic modelling, ideally including energy market/dispatch modelling, multi-sectoral modelling, or bespoke model development

• Prior experience in an advisory, consulting or client-facing analytical role this is not a back-office modelling role

• Tertiary qualification in engineering, economics, mathematics, statistics, actuarial studies or a related quantitative discipline; postgraduate qualification a plus, not essential

• Strong Python skills essential; experience with GAMS, PLEXOS or similar energy modelling tools highly regarded a self-driven appetite to pick up new tools matters just as much as tools already in hand

• Genuine interest in, or working knowledge of, energy markets and sectoral decarbonisation pathways (e.g. transport electrification, low-carbon liquid fuels, multi-sectoral modelling), balanced with flexibility to apply your skills in other sectors as needed
