About The Role

We are partnering with a leading global organisation seeking a Staff Engineer within their platform engineering team, focused on building next-generation machine identity and authentication systems that enable secure, large-scale distributed computing across global environments. The organisation operates at significant scale across multiple regions and is heavily investing in modern zero-trust architecture, with a strong focus on eliminating static credentials and enabling fully automated service-to-service authentication. This role sits within a highly technical engineering team responsible for designing and delivering foundational identity infrastructure across cloud platforms, APIs, and internal systems. Alongside hands-on engineering, you will engage with senior stakeholders to shape technical strategy, influence architecture direction and guide decision-making across the organisation.

What You’ll Be Doing
Lead the design and implementation of machine identity and authentication systems at scale
Architect secure integration across IAM, cloud platforms (e.g. AWS), API gateways, and service mesh settings
Develop production-grade identity systems and prototypes using up-to-date engineering practices
Replace legacy authentication mechanisms with up-to-date,



cryptographically sound approaches
Work hands-on across complex distributed systems challenges in identity and trust
Engage with stakeholders to define strategy and influence technical direction
Provide architectural leadership across engineering teams and platform initiatives

What you bring
Strong experience designing and building security or identity solutions at enterprise scale
Proven ability to write production-quality code in either Python or Go
Experience working across multiple identity layers including application authentication, cloud IAM (AWS/Azure/GCP), and API gateway security
Deep understanding of machine identity concepts, including certificates vs tokens and federation design
Hands-on experience debugging and operating distributed authentication systems
Ability to engage effectively with stakeholders while maintaining a strong delivery focus
Experience with workload identity platforms, service mesh or API gateway authentication, or contributions to identity/zero-trust projects will be highly regarded
