Initial contract until end of the year with view to extend long-term
We're looking for an experienced Solution Architect to join a major financial services transformation programme focused on modernising enterprise Identity & Access Management (IAM) capabilities.
This is an opportunity to play a key technical leadership role in designing the next generation of identity services, helping shape secure, scalable and cloud-native solutions within a large, complex enterprise environment.
Working closely with architects, engineering teams, security specialists and business stakeholders, you'll define solution architecture, establish technical standards and guide delivery across a large-scale IAM transformation programme.
What You'll Be Doing
- Define end-to-end solution architecture across business, application, data and infrastructure domains.
- Produce High Level Designs (HLDs), Low Level Designs (LLDs) and Architecture Decision Records (ADRs).
- Translate business, security and regulatory requirements into secure technical solutions.
- Design modern IAM capabilities covering:
- Authentication and Authorisation
- Human, Agent and Workload Identity
- Identity Federation
- API Security
- Policy-as-Code
- Secrets Management and PKI
- Design cloud-native architectures using Google Cloud Platform (GCP) and Kubernetes.
- Define integration patterns between identity platforms, applications and infrastructure.
- Develop resilient, highly available and scalable architectures.
- Support Architecture Review Boards and technical governance.
- Review supplier designs and provide technical assurance across multiple workstreams.
- Work closely with Product Owners and engineering teams throughout delivery.
- Mentor engineers and promote architectural best practice.
- Evaluate new technologies and contribute to the long-term architecture roadmap.
