Job description

Staff Software Engineer - Full Stack (Node.js, React, Next.js)

Build and shape secure, scalable full-stack authentication experiences used by customers across CommBank's digital channels. Take end-to-end ownership with significant scope to influence architecture, engineering practices and technical direction. Work with modern JavaScript technologies including Node.js, React, Next.js and GraphQL while helping advance AI-enabled engineering practices.

Do Work That Matters

We're building tomorrow's bank today, and our engineers are central to creating secure, seamless digital experiences for millions of customers.

As a Staff Software Engineer in Integration Excellence, you'll help shape the Group's customer authentication experience. You'll work end-to-end across customer-facing web applications and the Backend-for-Frontend (BFF) services that connect them with our identity platforms.

This is a hands‑on Staff engineering opportunity where you'll solve complex problems, influence technical decisions and turn high‑level requirements into resilient solutions. Your work may contribute to capabilities including login, multi‑factor authentication, passkeys and broader authentication integration.

You'll join a full‑stack engineering team building modern authentication capabilities used across CommBank digital experiences, including the CommBank App, NetBank, CommBiz and Bankwest.

Working primarily with the web squad and collaborating across a shared codebase, you will:

• Design and deliver end‑to‑end authentication solutions spanning React/Next.js experiences and Node.js BFF services.
• Shape scalable BFF and API architecture using REST and GraphQL where appropriate.
• Translate high‑level requirements into thoughtful system designs and production‑ready solutions.
• Design for secure token management, sessions, authentication state and integration with identity platforms.
• Build resilient cloud‑native services using modern distributed‑system and engineering patterns.
• Champion clean code, automated testing, observability, CI/CD and production reliability.
• Collaborate across engineering teams and channels to create reusable integration patterns and consistent customer experiences.
• Mentor engineers and influence technical decisions while remaining close to hands‑on engineering.

We're interested in hearing from people who:

• Bring strong full‑stack engineering capability and can demonstrate end‑to‑end technical ownership. You might lean towards back end or front end. What matters is your ability to understand and design the complete solution and collaborate effectively across both.
• Deep experience with Node.js and JavaScript/TypeScript , including designing and building backend or BFF services.
• Strong React experience together with familiarity or hands‑on experience with Next.js .
• Demonstrated system‑design capability , including turning broad requirements into scalable end‑to‑end solutions.
• Experience designing REST APIs , with GraphQL/Apollo experience highly regarded rather than essential.
• Understanding of cloud‑native and distributed architectures, application security, authentication or identity patterns and secure handling of sessions or tokens.
• Strong engineering fundamentals across automated testing, CI/CD, observability, reliability and clean, maintainable code.

Curiosity about AI‑assisted engineering and using modern tools to improve engineering quality and delivery will also help you thrive.

If you're excited by complex engineering problems and want to shape secure digital experiences at significant scale, we'd love to hear from you.
