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 solid 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 environments
- Develop production-grade identity systems and prototypes using modern engineering practices
- Replace legacy authentication mechanisms with modern,



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
