We are looking for an enthusiastic and inquisitive Senior Software Engineer with a passion for delivering secure, seamless customer experiences through modern identity and access management. You will have a strong foundation in CIAM concepts and protocols, paired with hands-on experience developing and operating secure applications in web and mobile environments.
You will contribute to shaping and delivering our CIAM strategy, acting as a trusted advisor across engineering teams while delivering secure, scalable solutions that enhance user experience. With a DevSecOps mindset, you will develop, deploy, and support applications using automation, best practices, and continuous improvement.
As a senior engineer, you will play a leading role in the squad - championing good engineering practices, mentoring others, and influencing the technical direction of CIAM integration across the business.

* Mentor engineers and promote knowledge sharing within the team and wider engineering community.
* Shape and advocate the CIAM technical strategy and roadmap in alignment with broader platform goals.
* Contribute to technical decision-making, architecture discussions, and engineering governance.
Implementation & Delivery
* Design and implement secure, scalable Customer Identity and Access Management (CIAM) solutions using modern technologies and cloud-native practices.
* Configure and support workflows for registration, authentication (including MFA, biometrics, social login), authorisation, and identity synchronisation.
* Create proof of concepts for securing services with various token types (ID, Access, User) and define reusable patterns.
* Develop high-quality software using React, NestJS, and related technologies in both web and mobile contexts.
* Support micro frontend architecture including module federation and independently deployed pipelines.
* Ensure CI/CD pipelines support testing, automation, and streamlined deployment of identity-enabled services.
* Maintain high standards of testing, including unit, integration, end-to-end, and performance testing.
Collaboration & Communication
* Act as a CIAM advisor to teams integrating identity capabilities into their platforms.
* Collaborate with stakeholders across engineering, product, security, and architecture to align on secure and user-centric identity experiences.
* Contribute to Chapter, Squad, and Guild forums to raise standards in security, reliability, and engineering culture.
