Job Description:

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.

Job Responsibility:

  • Build and deliver across the stack
  • Own your features end to end
  • Build with security in mind
  • Be a great teammate
  • Communicate proactively

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
  • A solutions-first mindset
  • A bias for action and a focus on shipping
  • Clear communication and collaboration
  • A collaborative spirit
  • A security-conscious approach

Nice to have:

  • 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
What we offer:
  • 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
  • Special discounts for employees, family, and friends
