* We're embarking on an engineering transformation with the key focus on innovating customer experience
* You have knowledge that spans both development and operations, including coding, infrastructure management, system admin/engineering and DevOps Toolchains.
* Together we will build tomorrow's bank today, using world-leading engineering, technology, and innovation.
Do work that matters
We're building tomorrow's bank today, which means we need creative and diverse engineers to help us redefine what customers expect from a bank. Envisioning new technologies that are still waiting to be invented and reimagining products that support our customers and help build Australia's future economy.
As a Staff Software Engineer in the Guidance & Investing Crew, you'll be at the forefront of work that truly matters—engineering the future of how millions of customers interact with the CommBank app every single day.
As a hands‐on technology leader with full‐stack experience, you'll lead a team of engineers designing and implementing solutions, while influencing Product Owners and Crew Tech Leads. Product‐aligned and customer‐obsessed, you'll own what you build end‐to‐end and work with modern technologies including .NET Core, AWS, containerisation, with exposure to NodeJS / NextJS and AI‐enabled solutions.
This is your opportunity to engineer with purpose, innovate at scale, and deliver customer‐first experiences that redefine digital banking.
We're interested in hearing from people who:
* Are passionate technology leaders who love being hands‐on, designing solutions, solving problems and owning outcomes end‐to‐end.
* Are strong mentors and people leaders who build engaged, curious engineering communities.
* Have experience across the full software development lifecycle, using Agile practices and DevSecOps.
* Lead the design and development of scalable, secure backend APIs in .NET/.NET Core, with a strong focus on high‐quality enterprise integrations and reliable downstream services. You'll be the technical backbone ensuring our platforms run smoothly at scale.
* Play a major role in shaping feature strategy and solution direction, partnering across multiple squads to align architecture, dependencies, and delivery plans. Your voice will influence how we build now and into the future.
* Bring strong architecture and solution design expertise to simplify complex problems and define clear, long‐term platform patterns. You'll help create elegant, resilient systems that scale with customer needs.
* Work with full stack engineering tooling and mindset to ensure seamless customer flows. You'll help create end‐to‐end solutions that feel cohesive and intuitive.
* Drive the safe, practical adoption of AI‐powered engineering tools to increase quality, speed, and automation. You'll be a role model, mentor engineers, and help shape modern engineering practices across the team.
Tech Skills
* Backend Engineering (.NET/C#): Delivers high‐performance backend services and enterprise‐grade microservices using .NET/.NET Core and clean architectural patterns.
* Frontend Capability: Uses React, Next.js, and TypeScript to deliver clean front‐end interfaces and integrate them seamlessly with backend APIs.
* Proficiency in .NET Core (preferred), C# or Java
* API & Integration Design: Builds secure, scalable APIs with strong downstream integrations across complex distributed systems.
* Cloud Engineering (AWS): Designs and operates cloud‐native solutions using Lambda, ECS/EKS, API Gateway, SQS/SNS, DocumentDB, DynamoDB, and CloudWatch.
* Observability & Reliability Engineering: Observe, Prometheus, Grafana.
* Quality Engineering & Test Practices: TDD, BDD, Unit, Component, Integration, E2E, Contract Testing (Specmatic).
* DevSecOps & Automation: Creates fully automated CI/CD pipelines and production‐ready workloads using Docker, Kubernetes, Terraform, and modern DevOps tooling.
* Practical exposure to monitoring stacks, Kafka and event‐driven architectures.
* AI & Agentic Development: GenAI, RooCode, Cline, Claude Code, GitHub Copilot.
* Strong focus on application security.
