About the Role
As a Staff Software Engineer on the CommBiz Mobile & Insight crew, you will influence the technical direction and build the services and applications that CommBank's business clients rely on. This is a full-stack role with opportunities to contribute to native mobile apps, backend services, APIs, and web frontends, while also mentoring other engineers.
Responsibilities
- Own the technical direction and roadmap for your areas, working with product and delivery leads to turn business goals into technical plans.
- Partner with your engineering manager to define engineering-led initiatives and workstreams that improve how we build and ship, including automation and tooling.
- Stay hands-on, designing and building microservices, backend-for-frontend (BFF) services, REST APIs, data access layers, third-party integrations and React/Next.js frontends.
- Lead complex initiatives across squads, from proof of concept through to production.
- Set and raise engineering standards for testing, safe deployment, observability and security.
- Grow engineers across squads through design reviews, pairing and mentoring, and share knowledge through guilds and internal writing.
- Own what you ship in production by leading complex troubleshooting and joining the on-call roster.
Requirements
- Deep, hands-on full-stack experience shipping and running backend services and APIs (C# .NET or TypeScript/Node.js) and web frontends (React/Next.js or Angular) in production.
- Experience designing systems at enterprise scale, including service boundaries, API contracts, relational and NoSQL data models, integrations and event-driven architecture, and ability to explain trade-offs clearly in writing.
- Experience leading technical work across multiple teams, bringing engineers and stakeholders along and challenging them when it matters.
- Ownership of quality and reliability end to end: automated testing, CI/CD, safe releases, logging, monitoring and incident response.
- Treat security as part of the design, not a final check.
- Mentoring senior and mid-level engineers, including those picking up a new part of the stack, and improving engineering practice beyond their own team.
- Effective use of AI-powered engineering tools (e.g. Claude, Copilot) and ability to help others do the same.
- Native iOS (Swift) or Android (Kotlin) experience is a bonus.
- Experience with GraphQL is a bonus.
- Experience building backends for mobile clients, including BFFs and APIs is a bonus.
