About the Role

We are looking for an experienced and versatile Infrastructure Engineer to join our team. This is a broad, hands-on role for someone who is comfortable operating across the modern infrastructure stack — spanning cloud platforms, virtualization, systems administration, automation, and network engineering.

This role replaces a traditional network-only function and reflects how we think about infrastructure today: as an interconnected discipline where networking, computing, security, and automation are inseparable. You will be a key contributor to the reliability, scalability, and security of our platforms, and a go-to escalation point for complex infrastructure challenges.

• Support the maintenance of both on prem and cloud infrastructure across AWS, Azure, or GCP including compute, storage, networking, and identity services

• Manage and optimize hybrid connectivity between on-premises environments and cloud platforms (VPN, ExpressRoute/Direct Connect, Transit Gateway)

• Govern infrastructure as code (IaC) using tools such as Terraform or Pulumi, ensuring environments are reproducible and version-controlled

Networking
