Sydney or Melbourne | 3 days/week in office

Package | Up $180k base + 5% bonus + super

n

The Opportunity:

n

Behind one of Australia's largest consumer tech brands sits one squad of engineers keeping the lights on for a critical service.

n

Every login. Every token. Every API call runs through this platform, used by millions of people every day.

n

You'll join the Public Identity Platform squad that owns every authenticated interaction across the business: the identity platform itself, authentication and authorisation, plus the developer portal and public API gateway that external businesses use to access the platform's APIs.

n

Identity engineering is one of the rare specialisations where the work touches everything, and this squad's roadmap over the next two years is as ambitious as it gets: evolving the identity platform and reshaping how external businesses consume the platform's APIs.

n

If you're a solid backend engineer who's touched auth and wants to go deep in it, or an identity engineer who wants consumer scale, this role's for you.

n

The Role:

n

n
- A senior IC position on a lean squad of 4 engineers, working alongside a platform expert with 10+ years on these systems and a newly hired Team Lead, with real ownership from day one.
n




- Senior engineers here take medium-sized initiatives from design through to production delivery themselves. High accountability, no hand-holding.
n
- The platform is in good shape. This isn't a rescue mission, the tech is modern and well maintained. The work is an ambitious roadmap: a major identity platform evolution serving millions of users, and reshaping how external businesses consume the platform's APIs.
n
- Mostly backend (80-90%), with occasional work on login experiences.
n

n

The Stack:

n

What You'll Bring:

n

n
- Working knowledge of modern authentication: OAuth2, OpenID Connect, token lifecycles, or hands-on integration with identity platforms (Cognito, Auth0, Okta, Azure AD or similar)
n
- Ideally, production time with Duende IdentityServer or IdentityServer4, identity provider migrations, or fine-grained authorisation systems (SpiceDB, OpenFGA or similar)
n
- You've built for scale on public-facing services, using microservices, event-driven patterns (SNS/SQS, EventBridge) and cloud platforms (AWS ideal)
n
- API gateway exposure is a plus: external developer onboarding, usage metering, credential management
n
- A track record of owning solutions end to end and mentoring those around you
n
- Bachelor's degree in a relevant technical field
