The Role:

Citi is seeking a Cloud Platform Developer to join its enterprise cloud engineering function, where you will contribute to the design and delivery of reusable infrastructure tooling, Kubernetes usage patterns, and Python-driven automation that accelerates cloud adoption across Citi's global engineering community. This is a platform engineering role — not application development or CI/CD pipeline work — focused on building the internal cloud services, Terraform modules, Helm patterns, and developer-facing blueprints that enable application teams to consume AWS and GCP resources securely and efficiently. Positioned within a competitive financial services technology landscape alongside peers at institutions such as JPMorgan Chase, Goldman Sachs, and Bank of America, this role offers high-impact, hands-on engineering work at enterprise scale. Ideal candidates are software engineers with 3–5 years of hands-on cloud and Kubernetes experience who are passionate about automation, infrastructure as code, and developer enablement.

Responsibilities

• Provision and manage cloud storage resources (AWS S3, GCP GCS) using Terraform and Harness, and execute Terraform plans across environments following established governance workflows.
• Build, enhance, and maintain Terraform modules for AWS/GCP services spanning compute, storage, networking, and IAM, with guidance from senior engineers.
• Develop and maintain Kubernetes and Helm patterns — including configuration of storage resources (PVs, PVCs, Storage Classes) — that simplify cloud-integrated workloads for consuming application teams.
• Write Python scripts, CLIs, and automation tooling for provisioning, data parsing and transformation, validation, diagnostics, and developer workflow support.
• Deploy and manage applications and storage components using Helm charts; perform CSI driver and sidecar upgrades following documented procedures.
• Define and support service contracts and integration interfaces used by application and platform teams, focusing on reliable consumption of cloud APIs, storage, IAM, and Kubernetes resources.
• Monitor and troubleshoot Kubernetes storage and cloud storage integrations, and perform routine maintenance including patching and version upgrades.
• Create blueprints, templates, reference architectures, and documentation that improve developer experience and accelerate cloud adoption across engineering teams.
• Validate infrastructure and application deployments across environments, and support continuous improvement of platform components.
• Collaborate with senior engineers on design improvements, implementation approaches, and documentation of infrastructure configurations, module usage, and operational procedures.

Qualifications

• 4-5 years' hands-on experience in software engineerin
