Full Job Description

We're embarking on an engineering transformation with the key focus on full-cycle engineering, automation and agentic AI services and agents.
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!

Step into a Staff Software Engineer role at the core of Consumer Finance, where the platforms you build shape how millions of customers pay, track and understand their everyday spending. Reporting into the Chapter Lead within the Consumer Spending Crew, you’ll work on critical capabilities such as credit card payment services, loyalty rewards, and the transformation of complex payment data into clear, real-time insights. You’ll design and build scalable web services and applications on AWS, while delivering modern, intuitive front ends using TypeScript, React and Next.js, including emerging AI-powered experiences. Your work underpins secure, high‑volume payment flows and rich data visualisations that help customers make better financial decisions every day.

This role goes beyond hands-on delivery into technical leadership and strategic influence. You’ll help shape the engineering roadmap, drive technical uplift across squads, and raise standards in cloud-native design, full‑stack engineering and modern development practices. Partnering closely with senior and executive leaders, you’ll turn strategy into outcomes while mentoring engineers and growing capability across the crew. The work is fast paced, highly collaborative and constantly evolving, with real customer impact at scale. If you’re motivated by solving complex problems and building technology people rely on daily, this is a role where your expertise truly matters.

See yourself in our team:

The Consumer Spending Crew is a tight‑knit, highly technical group within CBA’s broader Consumer Finance Domain, focused on building and evolving our credit card related services and products. This chapter owns critical platforms that process millions of transactions every day, operating at scale, under constant demand and with zero tolerance for failure. The team works end‑to‑end across modern, cloud‑based systems, covering authorisation, settlement, fraud prevention and real‑time decisioning, ensuring Australians can pay quickly, safely and confidently wherever they are.

Through the Consumer Spending lens, the work goes far beyond payments. The team applies advanced analytics and AI to translate complex, high‑volume spending data into meaningful stories, insights and reports that drive product innovation and better customer outcomes. By modernising legacy platforms, embedding intelligent risk models and enabling real‑time insights, this team has helped revolutionise CBA’s credit card services—making them smarter, more personalised and more resilient. It’s a team where deep technical expertise meets real‑world impact, shaping how millions of Australians interact with their money every single day.

We’re interested in hearing from people who:

Operate as a Staff Software Engineer (Full Stack) with full‑cycle, end‑to‑end ownership across design, build, run and optimisation.
Act as a technical SME and engineering leader , shaping long‑term technical strategy while remaining deeply hands‑on.
Design, build and operate robust, scalable, cloud‑native solutions using .NET, C#, AWS, React/Next.js and TypeScript.
Influence and evolve platform architecture , including microservices, event‑driven integrations and cloud‑native deployment patterns.
Champion engineering standards and best practices across software engineering processes.
Lead high‑quality delivery through CI/CD, test automation, observability and strong DevSecOps practices.
Bring a strong AI enablement mindset , with hands‑on exposure to AI‑assisted tooling and a clear drive to continuously upskill.
Apply AI‑assisted development and emerging agentic patterns to lift developer productivity and improve system design.

Tech skills:

We don't expect you to know everything, but experience in several of the following will set you up for success:

Back End: C#, .NET, PostgreSQL or other relational databases, REST APIs.
Front End: JavaScript, TypeScript, React, Next.js.
API Design & Integration: RESTful APIs, OpenAPI, API versioning, contract‑first design, OAuth 2.0, JWT, API Gateway patterns.
Cloud‑Native & Microservices: AWS services such as ECS, Lambda, S3, and RDS, microservices architecture, event‑driven systems.
Quality Engineering & Testing: Integration testing, contract testing, non-functional testing, API testing, test automation frameworks, Playwright.
DevSecOps & Automation: GitHub Actions, CI/CD, Infrastructure as Code, SAST, DAST, secrets management.
Observability & Reliability: CloudWatch, OpenTelemetry, distributed tracing, metrics, logging, alerting and production support.
AI Enablement & Assisted Engineering: LLMs, prompt and context engineering, AI coding assistants, MCP, RAG fundamentals, agentic AI concepts, agent orchestration.

If you're already part of the Commonwealth Bank Group (including Bankwest, x15ventures), you'll need to apply through Sidekick to submit a valid application. We’re keen to support you with the next step in your career.
