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.

  • 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.

Essential Skills & Experience
  • Strong background in Enterprise Solution Architecture

  • Extensive experience delivering Identity & Access Management (IAM) solutions

  • Authentication, Authorisation and Identity Federation (OIDC, OAuth2, SAML, SCIM)

  • Zero Trust Architecture

  • Agent Identity and Workload Identity

  • Cloud Architecture, particularly Google Cloud Platform (GCP)

  • Kubernetes and Service Mesh

  • API Architecture and API Security

  • Event-Driven Architecture

  • Policy-as-Code (OPA, Cedar or similar)

  • PKI, Certificates and Secrets Management

  • DevSecOps and CI/CD

  • High Availability, Disaster Recovery and Resilience Design

  • Security Architecture

  • Architecture Governance and Design Reviews

  • Strong stakeholder management and technical leadership experience

If you're an experienced Solution Architect with a strong IAM background and enjoy designing secure, enterprise-scale cloud solutions, we'd love to speak with you.
