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.

Mo te tūranga \| About the role
As a Senior Software Engineer, you'll be part of our team that is responsible for development activities relating to core integration development. Being part of the Digital and engineering Practice at ASB we encourage our teams to work autonomously in an agile way while actively growing their skills and expertise to continuously improve outcomes for our customers.
You'll have the opportunity to get hands-on with some interesting and complex pieces of work that integrate on an enterprise scale, all while being part of a smaller squad that makes their own decisions about how to work through prioritisation - so your voice will be heard, and your opinions valued.
Key Responsibilities:
Design, maintain, and develop API applications
Continuously improve processes and technology for scalability and high availability
Work with internal stakeholders to understand requirements and deliver solutions
Monitor, alert, and report on environments
Mentor and promote best practices within the team
Utilize CI/CD tools for efficient development and deployment

Troubleshoot, debug, and optimize code for performance and reliability
