Define telemetry and monitoring requirements for DNS services to ensure operational readiness.
Deliver DNS SME expertise across various DNS delivery platforms, encompassing F5 BIG-IP DNS and open-source software DNS servers.

What You Bring

Practical, hands-on experience in configuring and managing F5 BIG-IP DNS.
Solid grasp of IP networking basics relevant to DNS delivery.
Practical understanding of Linux runtime basics related to DNS services.
Demonstrated ability to operate as a senior SME and technical authority in a 24×7 production environment.
Strong incident leadership and structured troubleshooting skills, with experience producing RCAs and driving problem management.

Competitive remuneration and colleague discounts. Make life easier (and more affordable) with $80 monthly credit and 25% off Optus products and outstanding shopping discounts with our retail partners.
Flexible working arrangements with opportunities to work three days in the office, two days remote or home.
Vibrant and collaborative office campus that includes cafes, a convenience store, chill-out zones, GP, post office, gym, and on-site childcare centre.
Competitive leave policies, including additional 'Connected’ days to focus on culture, family, health, community, or whatever’s important to you.
We support growing families with inclusive, carer-neutral paid Parental Leave of up to 16 weeks.
Direct your own development and build future-ready skills with Optus U’s industry-focused micro-credentials, developed with La Trobe and Macquarie Universities.
Build meaningful connections through colleague-led networks and diversity initiatives including Culture Connect, Elevate Women, Disability Network, and Express Yourself (LGBTQIA+).
Put your wellbeing first with free access to counseling and support services, 24/7 — in-person, by phone, SMS, or video.
Free Optus bus from Macquarie University Metro Station (every 6-8 minutes); morning and afternoon.
