Step into a Principal Software Engineer role within the Bankwest Customer Support Experience Crew, leading the end-to-end build of next generation, AI powered customer platforms. This is a hands-on role grounded in modern .NET, system design, and cloud native engineering, where you’ll architect and deliver resilient, scalable solutions across AWS and Azure. You’ll drive the shift from traditional NLU chatbots to agentic AI systems, designing generative AI chat experiences that can reason, act, and resolve customer needs in real time. While Dynamics 365, Omnichannel, and Copilot Studio are part of the ecosystem, your focus is full cycle engineering—building robust services, APIs, and integrations that power always on, personalised support at scale.

Working across a multi crew model, you’ll act as a technical authority for AI driven engagement platforms, shaping architecture, standards, and delivery across the organisation. You’ll combine deep expertise in .NET, distributed systems, and cloud with emerging AI, embedding generative capabilities into critical journeys. Collaborating with cross functional teams, you’ll deliver secure, high performing systems while mentoring engineers and setting a high bar for quality. It’s a role that blends strategic thinking with hands on execution, giving you the platform to redefine customer support through cutting edge technology and make a lasting impact at principal level.
