About the role

We are seeking a Lead/Principal AWS Cloud Infrastructure Engineer to own the design, standardization, and operation of enterprise AWS infrastructure at scale. This is a technical leadership role responsible for landing zone and platform architecture, automation and governance frameworks, reliability and cost optimization, and for guiding engineering teams and engaging senior stakeholders and vendors.

In this role, you will:

● Lead the design and implementation of AWS landing zones, multi-account structures, and platform foundations using Control Tower, Organizations, and the Well-Architected Framework.

● Define and own infrastructure standards, reference architectures, and reusable Infrastructure-as-Code (Terraform preferred) modules consumed across teams.

● Architect and govern networking at scale — Transit Gateway, VPC design, VPN/Direct Connect, Route 53, PrivateLink, IPAM, and egress/SASE controls — within AWS service limits.

● Establish governance, security, and compliance frameworks — SCPs, IAM/identity models, KMS/Secrets Manager strategy, Config rules, tagging, and security baselines.

● Drive reliability engineering — multi-AZ/multi-region HA and DR design, backup strategy, capacity/quota planning, observability, and SLOs.

● Own cloud cost governance (FinOps) — optimisation strategy, budgeting, rightsizing, and chargeback/showback models.

● Lead end-to-end delivery of infrastructure programs and POCs, including orchestration/automation and migration/consolidation efforts.

● Provide technical leadership and mentoring; conduct architecture and code reviews; raise engineering maturity.

● Engage senior stakeholders, security/architecture review boards, and vendors (e.g., AWS, Zscaler) on design validation and roadmap.

● Evaluate emerging AWS services and define adoption recommendations and standards.

● Lead complex troubleshooting and root-cause analysis for high-impact incidents, driving corrective/preventive actions.

What you must have to be considered

• 6–10 years in cloud infrastructure, with deep hands-on AWS expertise at enterprise scale.

• Strong architecture experience across AWS compute, storage, networking, identity (IAM/Identity Center), and key managed services.

• Expert-level Infrastructure-as-Code (Terraform) — framework/module design, CI/CD, and policy-as-code.

• Proven experience with landing zones, multi-account governance, and Control Tower/Organizations design.

• Deep networking knowledge — hybrid connectivity, routing/BGP, segmentation, DNS, IPAM, and egress control; strong grasp of service limits and capacity planning.

• Strong understanding of cloud security, zero-trust principles, governance, and compliance frameworks.

• Experience leading delivery and mentoring engineers; strong stakeholder communication.

• Automation proficiency (Python/boto3, AWS CLI).

These will help you succeed

● Multi-cloud exposure (Azure and/or GCP) and multi-cloud governance experience.

● Experience with containers (EKS/ECS), GitOps, and platform-engineering practices.

● Familiarity with egress/SASE tooling (e.g., Zscaler) and large-scale IP remediation.

● Exposure to orchestration-based provisioning and account-vending automation.

Certifications: AWS Solutions Architect – Professional, DevOps Engineer – Professional, or Advanced Networking – Specialty
