Assistant Director – Operational Decision Intelligence - London

The opportunity

At EY-Parthenon, our unique combination of transformative strategy, transactions, tax and corporate finance delivers real-world value – solutions that work in practice, not just on paper. Benefiting from EY’s full spectrum of services, we’ve reimagined strategic consulting to work in a world of increasing complexity. With deep functional and sector expertise, paired with innovative AI-powered technology and an investor mindset, we partner with CEOs, boards, private equity and governments every step of the way.

EY-Parthenon’s Operational Decision Intelligence team is a rapidly growing part of our business that combines deep Operational Research, modelling and analytics expertise with a commercial consulting mindset to help clients address complex strategic and operational challenges.

We work with major corporate clients, government departments and other public sector bodies, advising them on complex strategic, commercial and operational decisions. Our projects often involve managing multiple stakeholders and high degrees of complexity and uncertainty. Decision making in this environment requires strong client management and communication skills, in addition to a rigorous analytical mindset and excellent data handling skills.

Although the team is largely London-based, we operate as a national team and many of our engagements involve multinational clients. This role will most likely require some travel within the UK and could require overseas working from time to time.

This role will specifically require Operational Research skills with experience in optimisation, supply chain modelling and analytics

  • Work directly with clients to design and build complex models/algorithms and employ insightful visualisation to translate the solution into an easy-to-understand outputs.
  • Identify opportunities for utilising AI to innovate and/or drive efficiency within projects.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
