Questions and answers about the job

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
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

Have experience with physical security infrastructure, including access control/badging and camera systems, and the networks that support them
Have deep systems knowledge across identity/directory services, backup and recovery, DNS, and cloud infrastructure (AWS)
Have a track record of documenting infrastructure clearly and designing to root cause rather than leaving recurring problems in place
Demonstrate strong ownership and sound judgment under pressure, communicating with clarity and respect and challenging thoughtfully when it matters
Have 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
If this role excites you, we encourage you to apply — even if you don’t check every box
Familiarity with automation and infrastructure-as-code, and structured IT governance or change management processes
Experience supporting a lab, manufacturing, or hardware/robotics environment, including OT/IoT networking considerations
Relevant certifications (e.g., CCNA/CCNP, network or security specializations)
