Strategy & Transactions – Rapid Prototyping Assistant Director, Analytics & AI, EY Parthenon

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.

We are now looking for a Senior Manager to join our Analytics & AI team, with a focus on rapid prototyping. This role blends high‑fidelity design, cutting‑edge web application development, and AI integration to bring client concepts to life. You will play a pivotal role in client discussions, solution delivery, and the creation of reusable assets that can scale across multiple engagements.

Your key responsibilities

• Lead the design and delivery of high‑fidelity wireframes and clickable prototypes using Figma, ensuring alignment with client needs and business objectives.
• Develop functional prototypes and proofs of concept using modern front‑end and back‑end technologies, ensuring solutions are both functional and scalable.
• Partner directly with clients to co‑create solutions in workshops, support client discussions with compelling demonstrations, and deliver working prototypes as part of engagements.
• Embed AI capabilities into solutions, including the use of LLMs, Retrieval‑Augmented Generation (RAG), and embeddings, to create innovative and practical applications.
• Balance hands‑on technical delivery with leadership and mentoring responsibilities, guiding a small team of developers and designers.
• Contribute to EY’s innovation agenda by building scalable assets that can be reused across multiple projects and markets.
• Collaborate across EY‑Parthenon and the broader EY network to ensure solutions integrate seamlessly with existing platforms and services.

Skills and attributes for success

• High proficiency in Figma for design and prototyping, with the ability to move seamlessly from concept to functional solution.
• Understanding of software engineering practices, including version control (Git).
• Front‑end development experience, ideally React and TypeScript, with exposure to component libraries such as ShadCN.
• Back‑end development to support functional prototyping, ideally Node.js, with helpful knowledge of Python.
• Familiarity with cloud platforms, ideally Azure, with an understanding of how to leverage services for rapid prototyping rather than deep infrastructure expertise.
• Proven ability to integrate and apply AI technologies such as LLMs, RAG, and embeddings in practical contexts.
• A mindset that embraces AI as a core part of day‑to‑day work, continually seeking opportunities to apply it in design, development, and delivery.
• Excellent problem‑solving skills, with the ability to translate complex requirements into working prototypes at pace.
• Strong communication skills, able to engage with both technical and non‑technical stakeholders.

We encourage you to apply even if you do not meet every listed requirement. We value potential, curiosity, and the ability to learn quickly as much as prior experience.

Ideally, you’ll also

• Be familiar with agile ways of working, including rapid iteration and co‑creation with clients.
• Have experience in data visualisation, translating data into clear and compelling visual stories.
• Bring experience of working in a consulting or professional services environment.
• Show curiosity for emerging technology trends, particularly in generative AI, human‑AI collaboration, and no‑code/low‑code accelerators.

What we look for

We are seeking someone who is comfortable combining technical skills, creativity, and a delivery‑focused mindset to create practical solutions. The ideal candidate is as comfortable designing in Figma as they are coding a web application, and is motivated by environments where ideas need to be turned into reality quickly. We are particularly interested in individuals who see AI as fundamental to how they work and are eager to apply it in creating innovative, practical solutions for clients.

What we offer you

We will fuel your ambition and potential with future‑focused skills development that equips you with state‑of‑the‑art methodologies and technology‑enabled solutions. With more than 25,000 people in 150 countries, you will join an inclusive and empowering culture that values your uniqueness, prioritises your wellbeing, and immerses you in the diverse thinking and cross‑cultural experiences necessary to help deliver impact to clients across the globe and to help build a better working world.

Are you ready to shape your future with confidence? Apply today.
