Staff

Software Engineer to help buildand tech leadour next-generation Developer Experience (Dev Ex) platform at Citiusing Kotlin.

You’llbe joining a small, high-impact team,shaping the daily lives of our 50,000 engineers globally bybuildingthecockpitwhereengineerscansee allparts of the software development life cycletied together intoaworkflow in near real-time, being able to action and monitor agentic AI flows from the cockpit. This is an exciting technical challenge for an ambitious candidate.

Where you’ll work

You’llsit within Development Enablement, part of Citi’s CTO organisation.

A group focused on innovation, developer platforms and internal tools used across the bank, where we experiment and ship fast, like a startup inside a global bank.

Our mission is to transform developerproductivitysavingourengineerstens of minutes per day, equating to £10,000,000sof savingsat

Citi’sscale.

You’llbe creating a near-real time platform that requests and receivesdata from across the bank, using a mixture of streaming (e.g. Kafka), webhooksand other integrations.

You’llbe creating a system that can orchestrate parts of theSDLC andcreate a lineage fromcommitto prodwith a mixture derived and source of truth systems.

You’llenable agenticworkflows across the bank at scale.
