Discover your future at Citi

Working at Citi is far more than just a job. A career with us means joining a team of more than 230,000 dedicated people from around the globe. At Citi, you’ll have the opportunity to grow your career, give back to your community and make a real impact.

Job Overview

Are you looking for career move that will allow to take a strategic project zero to one?  Then bring your extensive coding experience and passion for change and be part of the team building a green-field development at scale.

By joining Citi’s Common Platform Engineering team you help create and run the Generative AI platform for Citi. Our remit encompasses large scale engineering challenges on-premise and on cloud, along with cutting edge use of LLMs and supporting toolchains to address the use-cases of our users across the bank.

We are a startup within Citi, where everyone is actively coding. We need innovative and creative self-starters who have previous experience in developing large-scale platforms, data and ML, finance, platform engineering and SRE.

Our tech stack is diverse, encompassing (but not limited to) Python, Go, TypeScript, React, Kubernetes, Mongo, and Generative AI features requiring adaptability and a willingness to learn. 

Responsibilities:

  • Architect and deliver end-to-end LLM solutions – from experimentation to production 
  • Design evaluation frameworks to benchmark LLM performance, safety, and behaviour 
  • Build integration layers connecting LLMs to APIs, middleware, and enterprise systems 
  • Collaborate across teams to drive adoption of modern engineering practices and GenAI tooling 

Characteristics:

  • Able to identify and solve problems effectively 
  • Excellent communication and collaboration skills 
  • A self-starter with the ability to work effectively in teams and remotely 
  • Pragmatic, and a creative approach to managing risk 
  • An advocate of inclusion and diversity in every way 
  • A growth mindset and willingness to learn and adapt in a fast-paced environment 
  • Shows enthusiasm and develops trust through empathy 

Experience:

  • Proven experience as an Engineering Lead, Software Engineering Manager, or similar role 
  • Strong expertise in multiple programming languages (preferably Python, Go, and TypeScript), frameworks, and tools 
  • Have deployed LLM systems to production and understand evaluation, guard-railing, and monitoring 
  • Proven experience with distributed systems, event-driven architectures, container-based micro-services, distributed logs, SQL and NoSQL databases, and DevSecOps 
  • Experience working in a product focused team as opposed to a project focused team is beneficial 

What we’ll provide you

This is a unique role that will put you in the position to be part of a new venture and actively drive change. Every day there will be new challenges that will help you develop new skills that can drive your career.  

By joining Citi London, you will not only be part of a business casual workplace with a hybrid working model (up to 2 days working at home per week), but also receive a competitive base salary (which is annually reviewed), and enjoy a whole host of additional benefits such as:

  • 27 days annual leave (plus bank holidays)
  • A discretional annual performance related bonus
  • Private Medical Care & Life Insurance
  • Employee Assistance Program
  • Pension Plan
  • Paid Parental Leave
