Description

Systems and Network Security Engineer

Tucson, AZ | Onsite

Protect the Technology That Keeps Us Moving

Modern aviation depends on more than what goes into the aircraft. It depends on the technology, networks, systems, and security behind the people building it.

Universal Avionics is looking for a Systems and Network Security Engineer to help keep that environment secure, resilient, and running.

This is not a role where infrastructure and cybersecurity live in separate worlds.

You'll work across servers, networks, cloud environments, identity, security tooling, disaster recovery, and the systems our teams rely on every day. You'll solve problems when something breaks, strengthen the environment before something does, and help us make smarter security decisions as our technology evolves.

If you like understanding how everything connects, finding the weak points, and building systems that are harder to break and easier to trust, we want to talk to you.

What You'll Do

Own and strengthen critical server, network, cloud, and hybrid infrastructure

Administer and troubleshoot switches, routers, firewalls, wireless networks, VPNs, servers, virtualization, identity services, and core network services

Design security solutions that help us identify, protect, detect, respond to, and recover from cyber threats

Deploy and manage security technologies including SIEM, DLP, IPS/IDS, and endpoint detection and response

Apply identity-based access controls and zero-trust principles across on-premises and cloud environments

Evaluate vulnerabilities, conduct risk assessments, and help build security into new and existing technology

Monitor infrastructure health, availability, and security and respond when something isn't right

Strengthen backup, recovery, system hardening, monitoring, and incident-response practices

Stay current on emerging threats and translate what you're seeing into practical action

Mentor IT Support Specialists and help solve the technical problems that need another level of expertise

Partner across the business to make security part of everyday technology decisions

What You Bring

5-7 years of experience across systems administration, networking, cybersecurity, or a combination of these areas

Strong knowledge of network security principles, practices, and technologies

Hands-on experience with enterprise servers, networks, cloud or hybrid environments, and security tooling

Experience with technologies such as SIEM, DLP, IPS/IDS, EDR, firewalls, VPNs, virtualization, identity, and access controls

The ability to troubleshoot complex problems across systems rather than looking at each technology in isolation

Strong judgment when the pressure is on and systems need to get back online

The ability to communicate technical issues clearly to both technical and non-technical audiences

A bachelor's degree in a related field is preferred, or an equivalent combination of education and experience

Industry certifications in systems, networking, or security such as Microsoft, Cisco, CISSP, CISM, Security+, or equivalent are a plus

What We Stand For
