About The Position

Citi is seeking a Cloud Platform Developer to join its enterprise cloud engineering function. This role 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 focused on building internal cloud services, Terraform modules, Helm patterns, and developer-facing blueprints that enable application teams to consume AWS and GCP resources securely and efficiently. This role offers high-impact, hands-on engineering work at enterprise scale within a competitive financial services technology landscape.

Requirements

• 4-5 years' hands-on experience in software engineering or cloud platform engineering, with a strong foundation in software engineering principles including object-oriented programming and modular, maintainable code.
• Practical experience with Kubernetes and Helm, including deployment, storage resource configuration (PVs, PVCs, Storage Classes), and working knowledge of CSI drivers and sidecar management.
• Hands-on experience with Terraform for infrastructure provisioning via IaC; module authoring experience is a plus, though can be developed in this role.
• Proficiency in Python for scripting, automation, data parsing and transformation, CLI development, and validation tooling.
• Practical experience with AWS and/or GCP, including provisioning of compute, storage (S3/GCS), networking, and IAM resources; IaC-driven provisioning strongly preferred.
• Familiarity with Harness or similar infrastructure delivery platforms for executing and managing cloud provisioning workflows.
• Understanding of microservices architecture and how distributed applications consume platform APIs, cloud storage, IAM, networking, and Kubernetes services.
• Experience with Linux environments and comfort operating in command-line-driven infrastructure workflows.
• Strong interest in platform engineering, developer enablement, and automation with ability to produce clear documentation of infrastructure configurations and operational procedures.
• Strong troubleshooting and debugging skills across cloud infrastructure, IaC, and Kubernetes storage integrations, with a continuous improvement mindset.

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.

Benefits

• medical, dental & vision coverage
• 401(k)
• life, accident, and disability insurance
• wellness programs
• paid time off packages, including planned time off (vacation), unplanned time off (sick leave), and paid holidays
