Citi is one of the largest banks in the world, tracing its lineage to the City Bank of New York founded in 1812 and taking its modern shape through the 1998 merger that created Citigroup. Its most distinctive asset is a cross-border payments and treasury network unmatched by any competitor, moving trillions of dollars a day for multinational corporations, governments and other banks across roughly ninety countries. Alongside that institutional franchise it runs markets and investment banking, wealth management and a United States personal bank, and has spent recent years simplifying itself by exiting consumer operations across Asia, Europe and Latin America.

Overview of Citi:

Citi, the world leading global bank, has approximately 200 million customer accounts and a presence in more than 160 countries and jurisdictions worldwide.

  • Owning solutions that are expected to operate and perform at scale across the organisation.

  • Collaboration with multiple stakeholders and partners across Engineering and Operations as well as partner teams within the wider Citi organisation, across different time zones.

  • Highly motivated self-starter with excellent interpersonal and problem-solving skills

  • Bachelor’s degree or equivalent work experience

  • Good oral and written communication skills

  • Extensive relevant industry work experience

  • Hands-on experience integrating Container Image Scanning platforms and tooling

  • Experience contributing to the architecture and design (architecture, design patterns, reliability, scaling) of new and current systems

  • Experience of k8s and container technologies such as Docker, Podman and Openshift

  • Experience of security fundamentals with relation to a k8s platform and DevSecOps a bonus

  • Expertise in a major programming language such as Python or Java, and associated tooling (Git, Maven, IDEs, Jenkins, Bitbucket etc)

  • Expertise with DevOps, CI/CD and agile methodology

We offer:
