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.

Your key responsibilities

• Translate client needs into high-fidelity wireframes and clickable prototypes using Figma, ensuring alignment with business objectives.
• Build functional prototypes and proofs of concept using modern front-end and back-end technologies.
• Support client workshops and co-creation sessions, contributing to solution design and delivering compelling demonstrations.
• Embed AI capabilities such as LLMs, RAG, and embeddings into prototypes to create innovative applications.
• Take ownership of technical delivery on workstreams, while collaborating closely with the Senior Manager and broader team.
• Help build reusable assets and accelerators that can scale across projects.
• Contribute to team growth by mentoring junior developers and designers.

Skills and attributes for success

• Strong skills in Figma for design and prototyping, with the ability to move concepts into functional prototypes.
• Experience in front-end development (ideally React and TypeScript) with exposure to component libraries such as ShadCN.
• Back-end development experience (ideally Node.js, with helpful knowledge of Python).
• Understanding of software engineering practices, including Git version control.
• Familiarity with cloud platforms, ideally Azure, with a focus on leveraging services for prototyping.
• Curiosity and proven ability to apply AI technologies (LLMs, RAG, embeddings) in practical settings.
• Strong problem-solving skills, with the ability to deliver working solutions quickly.
• Confident communicator, able to collaborate 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

• Bring hands-on experience with rapid prototyping, whether through hackathons, proof-of-concept builds, or internal innovation projects.
• Be comfortable working iteratively, knowing when to move quickly to test ideas and when to refine solutions for client delivery.
• Show curiosity for emerging technology trends, especially in generative AI and human-AI collaboration.
