• Perform patch testing, deployments, and validation of devices and supporting infrastructure

• Troubleshoot complex issues across device, network, server, and platform layers

• Work with APIs, SaaS platforms, and hybrid cloud environments to enable secure integrations

• Support physical device handling, reformatting, and refurbishment using defined documentation and procedures

• Collaborate with network, security, platform teams, and external vendors to resolve issues and support rollouts

• Create and maintain technical documentation, runbooks, and operational process guides

• Ensure compliance with enterprise security standards, including authentication, authorization, and encryption requirements

• Participate in migration, refurbishment, and new rollout projects for IoT platforms and devices

Required Technical Skills

• Strong experience with Windows and Linux server engineering

• Solid networking fundamentals, including Layer 3 concepts (routing, subnets, DNS, DHCP)

• Hands‑on experience with IoT devices / hardware configuration and troubleshooting

• Working knowledge of APIs, system integrations, and technical environments

• Experience with SaaS platforms and enterprise authentication protocols (SAML, OIDC)

• Understanding of firewalls, proxy servers, and load balancers in enterprise environments

• Proven experience operating in L2 / early L3 support models

• Knowledge of security fundamentals, including encryption, authentication, and authorization

Experience & Profile
