About The Position

As a Senior IT Infrastructure specialist at Mytra, you will join our Corporate IT team during a period of rapid scaling. Our team is currently focused on building resilient, secure, and scalable networking, systems, and physical security infrastructure to support a fast-growing office, lab, and manufacturing environment, and we need a hands-on, technically deep specialist to help us design, harden, and operate the backbone that everything else at Mytra runs on.

Requirements

Proven experience designing and operating enterprise networks (switching, routing, VLANs, firewalls, wireless, and VPN), with 7+ years in IT infrastructure and at least 3 in a senior or lead capacity.
Deep systems knowledge across identity/directory services, backup and recovery, DNS, and cloud infrastructure (AWS).
Experience with physical security infrastructure, including access control/badging and camera systems, and the networks that support them.
Demonstrate strong ownership and sound judgment under pressure, communicating with clarity and respect and challenging thoughtfully when it matters.
Have a track record of documenting infrastructure clearly and designing to root cause rather than leaving recurring problems in place.

Nice To Haves

Relevant certifications (e.g., CCNA/CCNP, network or security specializations).
Experience supporting a lab, manufacturing, or hardware/robotics environment, including OT/IoT networking considerations.
Familiarity with automation and infrastructure-as-code, and structured IT governance or change management processes.

Responsibilities

Own the design and deployment of Mytra's core network (LAN/WLAN, switching, routing, firewalls, VPN, and ISP relationships) across our HQ, lab, and manufacturing spaces.
Own systems infrastructure, including identity and directory services, backup and recovery (Druva), and cloud/DNS architecture.
Own the physical security backbone, including badging and access control, camera and surveillance systems (Verkada), and the network and infrastructure that underpin them.
Lead infrastructure projects from requirements through vendor evaluation, procurement, and implementation, including capacity planning and buildouts for new spaces and headcount growth.
Design for reliability and resilience through redundancy, segmentation, and documented architecture, defining the standards that Cybersecurity enforces, and serve as the senior technical escalation point for complex networking and systems issues.
