Enterprise Interface Lead

Enterprise Interface Lead

Here at BNZ, it's about more than just banking. We work together in an agile, energising environment to create innovative solutions through 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. There is the opportunity for growth, learning and career development. No two days are the same.

This is an enterprise-wide engineering practice leadership role focused on interface design, API standards and integration patterns. Rather than owning delivery for a specific platform or domain, you will set direction, provide guidance and lead the governance and enablement processes that help teams design integrations that are simpler, safer and more resilient.

The role operates primarily through influence, enablement and evidence, rather than positional authority.

Responsibilities in this role include:

• Define and evolve enterprise interface and API standards, patterns and reusable assets.
• Lead the enterprise interface governance process, ensuring integration decisions are consistent, risk-aware and proportionate.
• Establish clear decision pathways and guardrails so teams understand when and how integration choices are reviewed.
• Provide pragmatic guidance on interface design trade-offs, reviewing designs and helping teams make well-reasoned decisions.
• Partner with Architecture and Platform teams to align interface standards, governance and enterprise outcomes.
• Drive adoption of interface standards through enablement, including playbooks, templates, guidance and communities of practice.
• Lift resilience, observability and incident-readiness expectations for critical integrations.
• Ensure interface governance supports delivery by being lightweight, transparent and focused on outcomes rather than compliance alone.
• Partner to ensure interface expectations are embedded into standards, tooling and delivery workflows.

You will partner closely with Architecture, Platform teams and delivery teams to reduce integration-related friction and operational risk, while still enabling teams to move at pace. The role operates primarily through influence, coaching and clear decision frameworks rather than positional authority.

A key aspect of this role is shaping the interface engineering craft and governance model at BNZ. This includes clarifying expectations, leading the enterprise interface governance process, and supporting capability growth and career progression for engineers working in integration-heavy roles.

You will help evolve BNZ's integration capability by:

• Standardising interface and API patterns across delivery teams.
• Establishing a clear, trusted interface governance model that enables good decisions without slowing teams down.
• Improving consistency in how teams design, expose and consume interfaces.
• Reducing avoidable complexity and technical debt in integrations.
• Strengthening observability and operational readiness for critical data flows and APIs.
• Supporting platform modernisation with clear, pragmatic integration standards and governance.
• Helping teams transition away from bespoke integration approaches toward reusable, well-understood patterns.

Success in this role looks like consistent, well-understood interface and API patterns used across Technology, supported by a governance process that teams trust. Integration decisions are clearer and faster, operational outcomes improve through stronger resilience and observability, and avoidable integration issues reduce. Engineers understand expectations, decision pathways are transparent, and interface governance is seen as an enabler rather than a blocker.

What skills & experience would be beneficial?

• Proven ability to influence and lead decision-making without relying on formal authority.
• Ability to communicate clearly from deep technical discussions through to senior leadership audiences.
• Strong technical credibility in enterprise integration and interface design.
• Experience defining or leading integration standards and governance in a complex or regulated environment.
• Deep understanding of modern integration patterns, including service- and event-driven approaches.
• An operational mindset, with strong appreciation for resilience, observability and incident readiness.
• A pragmatic, delivery-aware approach to governance that balances enterprise consistency with local needs.
