Here at BNZ, it's about more than just banking. We work together in an agile, energising environment to create innovative solutions though our promise "If you can imagine a better future, let's find a way."

We support wellbeing, flexible working and have a generous leave offering. No two days are the same.

Ko mātou tēnei | This is Us

The successful candidate will join BNZ’s Technology team within the Lending Platforms domain, a newly established team focused on improving the stability, resilience, security, and operational maturity of critical lending systems.

This team works across platforms and integration services that support lending application processing and decisioning for both personal and business customers, with a primary focus on Secured Lending.

The wider business unit is responsible for technology that underpins key lending experiences and services for BNZ customers.

As these platforms continue through a modernisation and retirement journey, the team plays an important role in ensuring they remain safe, reliable, compliant, and well-supported in the meantime.

The team partners closely with delivery, risk, data, vendor, and other technology teams to uplift platform health, improve production readiness, and strengthen supportability across the domain

Mō te Tūranga | About the Role

We sat down with the People Leader (who you would report to) and they told us the following about the role:

This is a 12 month fixed term role based in Wellington. It is a hybrid role with at least three days in the office and up to two days where you can work flexibly. Anchor days in the office are Tuesdays and Thursdays.

What are 5 day to day tasks the person in this role will complete?

• Own and support APIs, applications, and integrations that underpin BNZ’s Secured Lending platforms, including services integrated with third-party SaaS providers.

• Deliver reliability and operational improvements through software changes, automation, monitoring enhancements, and proactive maintenance.

• Support security and platform lifecycle activities such as patching, upgrades, vulnerability remediation, and risk reduction.

• Investigate production issues, perform incident triage and troubleshooting, and contribute to root cause analysis and long-term remediation.

• Create and uplift operational documentation, runbooks, support procedures, and production readiness practices to improve support outcomes and knowledge sharing.

What skills and experiences are required for this role?

We are looking for a senior engineer with strong experience in both software development and enterprise application support, ideally with 6–8+ years’ experience in complex environments.

The role requires hands-on capability across .NET and Java / Spring Boot applications and APIs, along with experience supporting systems in production.

Candidates should bring experience in operational and platform lifecycle work such as patching, upgrades, vulnerability remediation, and production support.

A solid understanding of distributed systems, API integration patterns, and security fundamentals such as API gateways, mTLS, JWT, and secure service communication is important.

Experience with CI/CD tooling such as Jenkins, Spinnaker, Docker, and Kubernetes, along with monitoring and observability tools like Splunk and Dynatrace, will be highly valuable.

Nice-to-have skills include React and TypeScript, automated testing experience such as JUnit and Rest-Assured, exposure to lending or financial services, and familiarity with WebSphere-based systems.

What attributes will this person display in order to be successful in this role?

The successful person will be proactive, dependable, and comfortable taking ownership of critical systems and outcomes.

They will bring a calm and methodical approach to production support, with the ability to work through complex issues and balance immediate response with longer-term improvement.

They will also be collaborative and communicative, able to build strong working relationships across engineering, delivery, risk, vendor, and business stakeholders.

Curiosity, pragmatism, and a continuous improvement mindset will be important, as this role is about leaving systems in a better state through disciplined operational practice, thoughtful engineering, and strong follow-through.
