Sr. Platform Engineer

Platform Engineering & Automation

Position Overview

The Sr Platform Engineer is responsible for designing, building, and continuously improving the firm's hybrid infrastructure platforms spanning on-premises datacenters and public cloud environments. This role focuses on platform engineering practices, automation, infrastructure-as-code, and operational excellence to deliver scalable, secure, and self-service infrastructure services.

The engineer will partner closely with cloud, networking, security, automation, and application teams to create reusable platform capabilities, automate infrastructure lifecycle management, and enable modernization initiatives across the enterprise. This position plays a key role in advancing the hybrid cloud strategy through platform standardization, governance, observability, cost optimization, and automation-first operational practices.

Key Responsibilities

Platform Engineering & Service Enablement

• Design, build, and maintain hybrid infrastructure platforms supporting public cloud and on-premises environments.
• Develop reusable platform services that enable self-service provisioning and standardized infrastructure deployment.
• Establish platform standards, golden images, reference architectures, and engineering guardrails.
• Contribute to enterprise platform roadmaps and modernization initiatives.

Infrastructure Automation & IaC

• Develop and maintain Infrastructure-as-Code solutions using Terraform, Terraform Cloud, Bicep, Ansible, and automation frameworks.
• Build automation workflows for provisioning, compliance validation, lifecycle management, patching, backup, and disaster recovery.
• Develop reusable infrastructure modules and automation pipelines following DevOps and Platform Engineering principles.

Cloud-enabled Operations & Support

• Engineer and optimize hybrid cloud environments across VMware Cloud Foundation, Azure, AWS, and future cloud platforms.
• Support a “Cloud Landing Zone” architecture pattern.
• Assist with workload discovery and migration readiness activities, then execute migration tasks (e.g., provisioning, cutovers, validation) for workloads moving to multi-cloud strategy.
• Infrastructure optimization and improve day-day management of on-premises compute, storage, and virtualization platforms (VMware vSphere) that would introduce efficiencies thru automated workflows.
• Experience managing a Cloud-enabled Identity and Directory Services implementing and maintaining Active Directory/Azure AD integration (Entra), RBAC/ABAC, policy-based access control, service principals, and secrets management across cloud environments.
• Support a hybrid network connectivity by implementing, validating, and troubleshooting connectivity between on-prem and cloud environments (e.g. SDWAN, ExpressRoute, Direct Connect, Private Gateways) in partnership with Network Reliability team, InfoSec, including segmentation, routing, firewall rules, load balancing, and latency/bandwidth requirements for target workloads.
• Familiarity with cloud governance & FinOps enablement by implementation of governance controls (guardrails, tagging, policy enforcement), cost management (FinOps) reporting, and securing a hybrid environment.

Relevant Skills & Experience

Required

• 8+ years supporting enterprise-scale infrastructure and multi-cloud hyperscalers (e.g. Azure, AWS, GCP).
• 5+ years working with Terraform and advanced understanding of Infrastructure-as-Code methodologies.
• Deep experience designing, building, and operating CI/CD pipelines and GitOps workflows using GitHub Actions, Jenkins, and enterprise source control platforms to enable automated, secure, and scalable infrastructure and application delivery.
• Experience building automation using Ansible, Bash, PowerShell, Python scripting, and REST APIs.
• Experience with cloud governance, policy management, and FinOps practices.
• Understanding of cloud networking, DNS, cloud-enabled identity services, security controls, and hybrid connectivity.
• Hands-on experience with Azure Monitor, Log Analytics, Application Insights, Grafana, Datadog, Splunk, or similar observability platforms.
• Familiarity with Internal Developer Platforms (IDP).

Preferred

• Experience with VMware Cloud Foundation (VCF), vSphere, and hybrid cloud architectures.
• Azure/AWS Solutions Architect or cloud-related certifications.
• HashiCorp Terraform Associate or Advanced certifications.
• Hands-on experience with Kubernetes, AKS, EKS, or OpenShift.
• Experience with Databricks infrastructure, AI platform hosting, or enterprise data platforms.
• Experience integrating AIOps, observability, or monitoring platforms.
