Staff Engineer | Cyber Security

Our team enables secure service-to-service authentication at enterprise scale. We architect machine identity systems and authentication integration layers across Macquarie, ensuring every service, API, and workload across 31 markets can authenticate securely without human intervention. We design how workload identity integrates with human IAM, cloud platforms, and API gateways to create unified zero-trust architecture.

We are a global financial services group operating in 30 markets with 57 years of unbroken profitability. At Macquarie, you’re empowered to shape a career that is fulfilling and creates value. You will bring your insights and expertise to the task at hand and feel supported as you make your own kind of impact for a better future.

You will build and deliver machine identity and authentication systems at Macquarie through hands-on engineering and technical leadership within your squad. You will solve hard problems, implementing workload identity infrastructure that integrates with cloud platforms, API gateways, and service meshes; building identity lifecycle automation that works at scale; delivering authentication solutions that span multiple identity layers. You will write production code, build tooling backed by working prototypes, own technical decisions within your domain, and raise the engineering bar through code review and mentorship.

• Experience building and operating workload identity infrastructure at scale - provisioning, rotating, and revoking identities for services across distributed systems
• Experience implementing across identity layers: human IAM, application auth (OAuth/OIDC), cloud IAM (AWS/Azure/GCP), and API gateways—making them work together in practice
• Knowledge of when machine identity should replace secrets, when to use attested identities vs tokens, and how to implement federation; you prove your views with working code and production data
• Experience that you ship production code (Python, Go), review architecture, debug distributed auth failures, and mentor engineers; you influence through working systems, not presentations
• Ability to engage with emerging identity patterns, contribute to internal standards, and bring practical improvements into the team's engineering practices
• Understanding of identity protocols, JWTs, and signing well enough to build secure identity systems on top
• Experience in identity lifecycle automation, SPIFFE/SPIRE implementation, HashiCorp Vault operation, service mesh or API gateway auth integration, or open-source contributions in identity projects is highly regarded.
