About the role

This is your chance to build the foundational systems for 'Citi Assist', a Generative AI assistant that will reach every Citi employee globally. You'll join us on the ground floor, becoming a core builder on a high-visibility platform that sets the standard for how a global bank adopts this technology safely and at scale. As a polyglot engineer, you'll work across the full stack. That means crafting intuitive user interfaces one day and building robust backend APIs the next. You'll be equally excited about both.

Requirements

Experience building and deploying production applications, whether that's frontend, backend, or both

Proficiency in at least two of these languages: Python, TypeScript/JavaScript, Go, or Java

Experience building user-facing features with modern frontend frameworks like React, Vue, or Angular

Experience building backend services and APIs that are reliable and maintainable

Comfort with containerised environments (we use OpenShift, but Kubernetes or Docker experience transfers well)

Practical experience with CI/CD pipelines and a belief in automating things

Solid experience working with relational databases like Postgres or MySQL

What matters most to us

A solutions-first mindset. You find the best path to solve the problem, whether that's writing new code, improving an old system, or integrating the right tool. The outcome is what matters.

A bias for action and a focus on shipping. You understand our goal is to deliver value to users, not just to write perfect code. You know when to be pragmatic and when to invest in technical excellence.

Clear communication and collaboration. You're proactive about sharing your progress and asking for help when you need it. You understand that keeping the team aligned helps everyone succeed.

A collaborative spirit. You find satisfaction in building high-quality software and you thrive in a team environment where you can learn from and help your peers.

A security-conscious approach. You see security and safety as part of the job, not an afterthought.

Bonus points for Direct experience with Generative AI concepts, LLMs, or related personal or professional projects

Contributions to open-source projects or a portfolio that demonstrates your range

Experience working in highly regulated environments

Our Tech Stack

We work with Python, TypeScript, Go, and Java on the backend. Our frontend is built with TypeScript, React, and Next.js. We use Postgres for our database, run everything on Kubernetes (specifically Red Hat OpenShift), and our DevOps setup includes GitHub and CI/CD tools like Tekton and Harness.

Our Team and Mission

We're the Common Platform Engineering team for GenAI, a central group in the Chief Technology Office. We're a focused agile team that owns our work from idea to production.
