Staff Software Engineer (Full Stack- Next.js, typescript & .Net)

Business Banking Technology | Sydney / Melbourne

We're modernising CBA's legacy CRM stack and building an AI-powered Banker Workbench that will transform how our bankers engage customers and manage their day.

As a Staff Software Engineer, you'll take technical leadership of a major new capability — the Task Centre — a greenfield feature that will become the "manage my day" hub for business bankers, consolidating tasks, regulatory commitments and AI-driven insights into one intelligent experience.

This is a high-impact role where you'll combine hands-on engineering with technical strategy, mentoring, and cross-squad influence.

What you'll do

• Lead the design and delivery of a new AI-enabled Task Centre within the Banker Workbench
• Provide front-end technical leadership across the squad (Actionable Insights)
• Architect and build modern, scalable solutions using Next.js, TypeScript and React
• Collaborate closely with senior engineers, product and cross-domain teams
• Shape solution architecture and engineering standards
• Mentor engineers across Australia and India
• Embed DevOps, observability, quality engineering and secure-by-design practices
• Drive pragmatic AI integration into user workflows (LLMs, AI-assisted features)

Tech Stack & Environment

Front-end focus:

• Next.js
• TypeScript
• React
• State management (Redux or similar)
• Modern UI/UX patterns

Back-end & Platform:

• .NET
• AWS (Azure/GCP experience also welcome)
• CI/CD (GitHub Actions, TeamCity, Octopus or similar)
• Observability & security tooling (logging, monitoring, Snyk, SonarQube, etc.)

AI & Modern Engineering:

• Desirable: Experience integrating AI/LLMs into applications
• Desirable: Familiarity with tools like LangChain, LlamaIndex or similar
• Strong user-centric thinking around AI-driven workflows
• Comfortable leveraging AI coding tools (e.g. GitHub Copilot, Claude, RooCode etc.)

What we're looking for

• Proven experience operating at Staff Engineer level or equivalent senior technical leadership
• Strong front-end engineering depth with full-stack awareness
• Ability to lead technical direction while remaining hands-on
• Experience modernising legacy systems or building greenfield capabilities
• Strong stakeholder communication and collaboration skills
• Passion for engineering excellence, clean architecture and continuous improvement

Why this role is different

• You'll help modernise a critical banking platform used daily by business bankers
• You'll build a brand-new AI-powered feature, not just maintain legacy code
• You'll influence architecture across multiple squads
• You'll work on real-world AI integration, not just experimentation
• You'll help shape the future CRM experience at one of Australia's largest banks
