Systems & Network Security Engineer in Tucson, Arizona at Universal Avionics

Tucson, AZ | Onsite

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.

• 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

• 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

How we work matters just as much as what we do.
