Do work that matters

We’re building the bank of tomorrow and need creative engineers to help shape what customers expect. You’ll work on digital products and technologies that make a real difference for millions of Australians.

Technology powers everything we do from secure transactions to award-winning platforms. Our teams are product-led, autonomous, and own delivery from start to finish. Here, you’ll turn your passion for software into real-world impact creating smart, seamless experiences for customers and colleagues

See yourself in our team

As a Staff Engineer, you’ll shape the technical direction of your squad in Group Strategy and Technology. You’ll work with engineers, product managers, and designers to architect scalable, secure systems.

This hands-on leadership role blends technical depth with architectural vision and mentoring. You’ll guide engineering practices, influence system design, and drive innovation using AI where it adds real value.

We’re interested in hearing from people who:

• Are passionate technology leaders who architect, design, and guide solutions from concept to delivery
• Build enterprise-grade financial systems with embedded Agentic AI capabilities
• Drive the integration of autonomous AI agents across key banking use cases
• Partner with data scientists and engineers to deliver intelligent, adaptive platforms
• Establish architectural standards and ensure compliance with financial regulations
• Explore emerging technologies and lead strategic adoption across AI, cloud, and finance
• Provide technical leadership through architecture reviews and cross-team collaboration
• Mentor engineering teams and champion a culture of innovation and experimentation
• Align technical decisions with customer needs and strategic business goals
• Influence architectural direction through clear communication and stakeholder engagement
• Actively explore emerging technologies to enhance how we build

Technical Skills

We use a wide range of technologies and don’t expect you to know them all, but experience in some of the following will set you up for success:

• Frontend: React, TypeScript, Next.js, scalable design systems (Figma-based, token-driven, micro-frontend strategy)
• Backend: Python (FastAPI), Node.js (Fastify), Java, .NET Core, C#, API-first design, service decomposition, CQRS, DDD
• Databases: SQL, NoSQL (Postgres, MongoDB), distributed data modelling, event sourcing
• Data Technologies: AWS-native tools (DynamoDB, Aurora, S3, Glue, Athena, Redshift), data lake/warehouse architecture, governance and lineage
• Architecture: Microservices, event-driven systems, distributed design, service orchestration, domain-driven design
• Cloud: AWS (Certified Developer/Architect), Azure, multi-account strategy, infrastructure as code (Terraform/CDK), hybrid cloud integration
• DevOps: GitHub Actions, Jenkins, CI/CD pipelines, developer experience enablement, secrets management
• Containers: Docker, Kubernetes, service mesh (Istio), autoscaling, resilience patterns
• Security: Secure-by-design systems, threat modelling, IAM, zero trust architecture
• Testing: Unit, regression, contract testing, CI/CD automation, shift-left testing, release governance
• Observability: Prometheus, Grafana, OpenTelemetry (distributed tracing, SLOs/SLIs, incident response)
• AI & Emerging Technology
• Frontend: React, TypeScript, Next.js, scalable design systems (Figma-based, token-driven, micro-frontend strategy)

While this role isn’t AI-first, we value engineers who:

• Understand how AI and machine learning can enhance engineering workflows
• Build or integrate AI-assisted tools and GenAI applications (e.g. LangChain, LlamaIndex, GenAI APIs)
• Use AI-powered coding assistants like GitHub Copilot, Cursor, Continue, or Aider
• Are curious about agentic systems and real-world AI experimentation
