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.

You’ll join as a hands-on Technical Lead within a senior product engineering organisation responsible for building and scaling critical platform capabilities used across the company’s ecosystem.

A major focus of the role is leading the evolution of authentication and authorisation systems - helping shape secure, scalable identity infrastructure across both internal and customer-facing products.

You’ll remain deeply technical while leading architectural direction, mentoring engineers, and partnering closely with Product, Design, Security, and Infrastructure teams to deliver highly scalable systems end-to-end.

The environment is fast-moving, product-led, and highly collaborative - with strong engineering standards and genuine autonomy.
