Citi operates across 200+ years of banking infrastructure, now modernizing core systems through cloud adoption (AWS, Azure, GCP) and streaming data platforms (Kafka, Flink, Pinot) while phasing out legacy analytics (replacing SAS). The hiring profile skews heavily toward finance and operations roles—over 1,900 open positions with finance alone accounting for 36%—signaling sustained focus on compliance, regulatory controls, and operational risk management rather than product velocity.
