## Description

We are Citi's ICG Technology Strategy team, a startup with the exciting mission of shaping the direction of travel for the ICG by defining the tech and engineering strategy for the bank. We are a team of talented engineers, product managers and tech SMEs, taking ambiguous concepts and making them real by engineering cutting edge products at planetary scale! We are solely focused on the most modern technology and engineering disciplines such as generative AI, cloud, security, modern app stacks (with Golang, Gatekeeper), open source and the latest and greatest in the Kubernetes ecosystem.

Generative AI is a relatively new and growing space, as a result, we ask that you share with us a specific AI engineering projects on LLMs that you're proud of in your application. Ideally these projects should show off complex and clever architectures or a systematic evaluation of an LLM's behaviour.

You might be a good fit if you

 * Bring your deep-dive software engineering expertise
 * Thrive in a results-driven environment, where flexibility fuels impact
 * Be a game-changer, ready to step beyond your designated role
 * Love the synergy of pair programming? So do we!
 * Seize the opportunity to explore machine learning and its real-world applications at scale. Jump in!
 * A relentless passion to learn more about machine learning and generative AI, bringing your knowledge to shape Citi's future.

What you'll do within the Business Architecture team:

 * Contribute to the 0-1 build of multiple AI products
 * Design and build high-quality, highly reliable products with user experience at the centre
 * Be responsible for engineering innovative, best in class AI platforms for the bank
 * Creating firsts in the Generative AI space for Citi as part of the team that defines the strategic direction for the bank
 * Continually iterate and scale Generative AI products, whilst listening to the needs of the customers (internal)
 * Mentor and nurture other engineers to help them grow their skills and expertise
