What’s the role?
As a Principal Platform Engineer, you will be part of the ServiceNow Platform Engineering team and play a key role in ensuring Westpac has an accurate, current, and trusted view of its infrastructure and application landscape within ServiceNow. You will be accountable for the quality, currency, and reliability of Discovery and CMDB data, supporting critical incident, problem, event, alert, and change processes across the bank. While Discovery outcomes are central to the role, you will also contribute to broader platform engineering initiatives, provide higher‑level (L3) operational support when required, and help shape enterprise Discovery and CMDB capability to ensure long‑term platform sustainability.
Key responsibilities

- Operate, maintain, and continuously improve automated and scheduled Discovery processes
- Validate, analyse, and remediate data quality issues to maintain trusted configuration data
- Maintain currency of Discovery patterns, plugins, and related ServiceNow platform components
- Extend Discovery capability through patterns, classifiers, business rules, scripting, and audits
- Partner with Platform Engineering, ITSM, ITOM, and data practices to support CMDB integrity and outcomes
- Act as a trusted advisor to internal customers and own engineering‑led initiatives from concept through delivery
What do I need?
- Strong infrastructure and application engineering experience, with a clear understanding of what is being discovered and why it matters
- ServiceNow Discovery experience is not required, with an expectation to quickly build ServiceNow capability and actively learn the platform
- Willingness to work towards relevant ServiceNow certifications with support from the team
- Strong domain knowledge combined with a problem‑solving mindset and ownership of outcomes
- Extensive experience in infrastructure and application engineering within complex enterprise environments
- Strong understanding of modern and legacy platforms, including cloud, virtualisation, and container technologies
- Decent to advanced JavaScript capability
- Strong analytical and problem‑solving skills, with the ability to reason about dependencies, relationships, and impact
- Clear focus on outcomes and the ability to prioritise work effectively
- Strong communication and collaboration skills
- Willingness to learn and apply ServiceNow Discovery concepts and tooling
- SQL skills considered a bonus
