Mō Mātou | About us

At ASB, we’re more than a bank, we’re a purpose-led organisation helping people, communities, and our environment thrive together. With a proud history and a clear vision to support New Zealanders in getting one step ahead, our work is guided by the values of Courage, Care, and Curiosity. We’re bold in challenging the status quo, we genuinely care about those we work with and serve, and we’re always exploring new ideas to improve how we work.

As one of Aotearoa’s most trusted banking partners, we offer the scale and stability of a large organisation, while recognising and valuing each person’s contribution. Your ideas, growth, and impact matter here and you’ll be supported to do meaningful work every day.

Mō te Tūranga | About the role

As a Senior Security Engineer, you’ll play a key role in the Internet Protection squad responsible for supporting and evolving ASB’s zero trust network and internet cyber security platforms. The squad is an important part of the wider Infrastructure Services platform team, delivering the bank’s critical infrastructure and systems to ensure its availability for our stakeholders and customers.

In the Senior Security Engineer role you will contribute across the full Infrastructure lifecycle, from hands-on operational support through to design and delivery of new capabilities, in an agile environment. You will leverage your skills in automation and scripting to optimise the squad’s activities across proxy, DLP and remote access technology systems. Working closely with engineers, squads, and stakeholders across the bank, you’ll bring advanced technical expertise, practical guidance, and a collaborative mindset to everything you do.

Architecture and solution design knowledge

In addition, the following would be an advantage:

Good understanding and experience of working using Agile principles.
