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.
What You'll Do
Cloud & Hybrid Infrastructure
- 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
- Participate in ongoing management of network infrastructure including routers, switches, firewalls, and load balancers
- Manage and troubleshoot LAN/WAN, SD-WAN, VPN, BGP/OSPF, and VLAN environments
- Administer DNS, DHCP, and IP address management (IPAM) across hybrid environments
- Review and enforce network security policies, firewall rules, and segmentation strategies in collaboration with the security team
Systems & Virtualization
- Administer virtualized environments (VMware vSphere, Hyper-V, or equivalent) and container platforms (Kubernetes, Docker)
- Manage server operating systems at scale across Linux (RHEL/Ubuntu) and Windows Server
Monitoring, Reliability & Security
- Maintain observability tooling including infrastructure monitoring, alerting, and log aggregation (e.g. Datadog, Prometheus/Grafana, Splunk, or similar)
- Participate in an on-call rotation for infrastructure-level incidents, driving timely resolution and thorough post-incident reviews
- Contribute to backup, disaster recovery, and business continuity planning and testing
- Partner with the security team on vulnerability management, patching cadences, and hardening standards
Automation & Continuous Improvement
- Identify and drive automation opportunities to reduce toil and improve consistency across the infrastructure estate
- Contribute to capacity planning and infrastructure roadmap discussions
- Mentor P1/P2 engineers and share knowledge through internal documentation and team sessions
What You'll Bring
Experience & Skills
- 4–7 years of experience in infrastructure, network engineering, or a related discipline
- Strong networking fundamentals and hands-on experience with enterprise network platforms (Cisco, Juniper, Palo Alto, Fortinet, or similar)
- Proven experience with at least one major cloud platform (AWS, Azure, or GCP) — ideally with a cloud associate-level certification or equivalent practical experience
- Experience managing Linux and Windows Server environments in production
- Familiarity with containerization concepts and platforms (Docker, Kubernetes)
- Experience with monitoring and observability tooling in a production environment
- Strong troubleshooting skills across network, compute, and storage layers
- Comfortable working in an on-call capacity for infrastructure incidents
Nice to Have
- Working knowledge of infrastructure as code and configuration management tools (Terraform, Ansible, or similar)
- Experience with SD-WAN platforms (e.g. Meraki, Viptela/Cisco SDWAN, VMware VeloCloud)
