The engineer will build reusable IaC modules and secure multi-cloud patterns,

implement network and security controls, automate infrastructure through CI/CD

and policy-as-code, and establish standardized self-service capabilities for

engineering teams. The role will also support AI and agentic enablement,

orchestrating secure connectivity, identity, API/tool access, and infrastructure

patterns for deploying agentic workloads across multi-cloud environments.

RESPONSIBILITIES

* 7+ years of infrastructure engineering experience with strong expertise in

Infrastructure as Code (IaC) using Terraform, OpenTofu, or similar

frameworks.

* 7+ years of hands-on experience designing and automating infrastructure

across Google Cloud Platform (GCP), AWS, and/or Azure, with an emphasis on

reusable, standardized multi-cloud patterns.

* Strong knowledge of cloud networking, including VPC/VNet architecture,

subnets, routing, DNS, NAT, load balancing, private connectivity, peering,

transit architectures, VPN, and dedicated interconnects.

* Deep understanding of network security, including security groups, firewall

policies/rules, network ACLs, micro-segmentation, ingress/egress controls,

private endpoints, and Zero Trust principles.

across applications, environments, business units, and cloud platforms.

* Strong experience with API gateways and API infrastructure, including secure

ingress/egress, authentication and authorization, rate limiting, routing,

policy enforcement, private APIs, and service-to-service connectivity.

* Experience designing secure connectivity for Kubernetes and containerized

workloads, including GKE/EKS/AKS networking, network policies, service

ingress/egress, and workload isolation.

* Strong understanding of IAM, secrets management, encryption,

certificates/PKI, and cloud security architecture, with the ability to

integrate these controls into IaC modules and deployment pipelines.

* Proven experience building enterprise-grade reusable Terraform modules,

policy-driven infrastructure patterns, CI/CD integrations, automated testing,

and infrastructure governance.

* Experience designing and operating large-scale, highly available, resilient

multi-cloud infrastructure using standardized automation and security

controls.

* Strong understanding of distributed systems, microservices,

service-to-service communication, and modern application connectivity

patterns.

* Experience enabling AI/agentic workloads in multi-cloud environments,

including secure agent-to-API/tool connectivity, identity and authorization,

controlled network access, API gateway integration, secrets handling, and

infrastructure automation for agentic platforms.

QUALIFICATIONS

* Experience developing multi-cloud network and security architectures spanning

GCP, AWS, Azure, on-premises, and SaaS environments.

* Experience building IaC platform capabilities such as reusable modules,

golden patterns, self-service infrastructure, policy-as-code, automated

compliance, and developer enablement.

* Experience with network security platforms and cloud-native controls, such as

micro-segmentation, and secure-by-default infrastructure design.

* Experience with policy-as-code and security automation using technologies

such as OPA, Sentinel, organization policies, IAM policies, and automated IaC

security scanning.

* Experience with FinOps and cloud cost optimization, particularly network,

data-transfer, NAT, load-balancing, API, and multi-cloud connectivity costs.

* Experience enabling agentic AI platforms and AI infrastructure, including

secure access to enterprise APIs, MCP/tool integrations, agent identity,

guardrails, observability, and controlled cross-cloud connectivity.

* Experience establishing IaC standards and governance for AI/agentic

infrastructure, enabling engineering teams to provision secure networking,

APIs, compute, identity, and security controls through reusable modules.

* Relevant certifications such as HashiCorp Terraform Associate, GCP

Professional Cloud Network Engineer/Cloud Architect/Cloud Security Engineer,
