We're the team that makes cryptographic services invisible and machine identity secure at enterprise scale. We own PKI, secrets management, cryptographic controls, and machine identity systems across Macquarie - enabling zero-trust architecture and ensuring every service, API, and workload across 31 markets can authenticate securely without human intervention.

At Macquarie, our advantage is bringing together diverse people and empowering them to shape all kinds of possibilities. We are a global financial services group operating in 31 markets and with 56 years of unbroken profitability. You’ll be part of a friendly and supportive team where everyone - no matter what role - contributes ideas and drives outcomes.

You'll be an enterprise-level Principal Engineer building next-generation cryptographic systems and machine identity services at scale. You'll solve the hardest technical problems in cryptography and non-human identity - not by accepting limitations, but by prototyping what's technically possible and proving it works at enterprise scale. You'll design and implement production cryptographic systems, experiment with emerging technologies like confidential computing and post-quantum cryptography, build working prototypes that platform teams can adopt, and share technical depth through architecture documentation and mentorship. You'll be ahead of the curve, experimenting with emerging cryptographic technologies before the industry standardises them.

We love hearing from anyone inspired to build a better future with us, if you're excited about the role or working at Macquarie we encourage you to apply.
