The Company:
Trust, identity, and secure access are becoming foundational layers of modern AI-enabled software at scale.
We’re partnering with a globally recognised technology company building products used by millions of users across research, AI, and enterprise environments. Their platform enables organisations to build better systems through high-quality human feedback, data infrastructure, and trusted user interactions.
Following sustained growth and increasing global adoption, the business is investing heavily into its core platform engineering function - particularly around authentication, authorisation, and identity architecture as the platform scales internationally.
This is a highly product-centric engineering environment where technical leadership, customer empathy, and engineering quality all carry equal weight.
