Who We Are:

SiriusXM and its brands (Pandora, SXM Media, AdsWizz, Simplecast, and SiriusXM Connected Vehicle Services) are leading a new era of audio entertainment and services by delivering the most compelling subscription and ad-supported audio entertainment experience for listeners - in the car, at home, and anywhere on the go with connected devices. Our vision is to shape the future of audio, where everyone can be effortlessly connected to the voices, stories and music they love wherever they are.

We are proud to have launched a new state-of-the-art technology facility in Dublin, Ireland. The Dublin-based team plays a critical role in our continued digital transformation, and functions as a center of excellence for SiriusXM’s global Product and Technology organization.

SiriusXM’s new Dublin facility comprises a workforce focused on software development, automotive technology and engineering, adtech, data science, and analytics. Talent based in Dublin will be charged with developing and implementing best-in-class standards for high-quality, scalable software deliveries for SiriusXM’s streaming and in-vehicle audio entertainment platforms.

How You'll Make an Impact:

The Enterprise Network & Security team designs, secures, and operates the enterprise-facing infrastructure that provides critical interconnectivity for employees and partners. We are seeking a Network Security Engineer to strengthen our global security posture by focusing on the design, implementation, and management of next-generation firewalls, load balancers, and other network security platforms. The successful candidate will lead efforts to enforce security policies, improve resiliency, and ensure compliance across broadcast, data center, and enterprise network environments, while also mentoring peers and driving innovation in security best practices.

What You'll Do:

Design, implement, and manage enterprise firewalls, load balancers, and related network security platforms.
Deploy, monitor, and optimize network security controls across enterprise, broadcast, and data center networks.
Triage, diagnose, and resolve firewall, load balancing, and VPN-related incidents.
Ensure compliance with InfoSec requirements and industry-standard security frameworks.
Drive automation efforts to standardize firewall and security policy management (“security as code”).
Collaborate with InfoSec, broadcast engineering, and enterprise infrastructure teams to enforce security policies and respond to new requirements.
Create and maintain documentation for security standards, policies, and operational procedures.
Provide subject matter expertise on network security to cross-functional engineering teams.
Participate in on-call rotation for operational network and security support.

What You'll Need:

Bachelor’s Degree in Computer Science, Computer Engineering, or related field.
3+ years of experience working in enterprise network security environments.
Excellent interpersonal, communication, and presentation skills.
Ability to work independently and collaboratively in high-pressure environments.
Strong organizational skills with the ability to handle multiple priorities.
Commitment to delivering high-quality internal customer service.
Proficiency with documentation and productivity tools such as Google Workspace, LucidChart/Visio, and MS Office.
Hands-on expertise with Palo Alto firewalls, VPN technologies (GlobalProtect, AnyConnect, IPsec), and security policy enforcement.
Strong experience with F5 load balancers (LTM/GTM/ASM/AFM) and traffic management policies.
Knowledge of Cisco ASA firewalls and other major vendor platforms (Juniper, Arista, etc.).
Familiarity with zero-trust access control solutions (ClearPass, Cisco ISE).
Solid understanding of network protocols (TCP/UDP, IPv4/IPv6, BGP, OSPF, VXLAN, EVPN, IP Multicast).
Experience with automation frameworks (Python, Ansible, Terraform, Go) for network security operations.
Skilled in network monitoring and troubleshooting tools (Wireshark, NetFlow, Syslog; OpenNMS, SolarWinds, or Datadog a plus).
Ability to take ownership of critical issues through resolution and support on-call rotations.

Our goal at SiriusXM is to provide and maintain a work environment that fosters mutual respect, professionalism and cooperation. SiriusXM is an equal opportunity employer that does not discriminate on the basis of actual or perceived race, creed, color, religion, national origin, ancestry, alienage or citizenship status, age, disability or handicap, sex, gender identity, marital status, familial status, veteran status, sexual orientation or any other characteristic protected by applicable laws.

The requirements and duties described above may be modified or waived by the Company in its sole discretion without notice.
