Adoption Software Engineer - Authorisation

Barclays • Contract • United Kingdom • 12h ago

Location: Glasgow, London or Radbroke (Hybrid)

Overall purpose of the role:

We are seeking an Adoption Software Engineer to join Barclays working with a global-scale technology platform used by millions of users worldwide. In this role, you'll be instrumental in driving the adoption of modern software engineering practices and technologies, particularly around authorisation, policy-as-code, and cloud-based deployment, working closely with development teams and business stakeholders across the organisation. This is a high-impact role within an engineering-led environment, offering the chance to shape the future of authorisation technology and adoption across a globally-used platform.

Key Accountabilities

Champion the adoption and implementation of authorisation frameworks, using your experience in policy-as-code using Styra OPA, or alternatives such as OPAL or Permit.io.
Work across the full stack, from UI to backend and data layers, on systems handling over 24,000 transactions per second, with low-latency (sub-second) performance.
Support and enhance systems deployed across AWS (preferred), or Azure / GCP, with experience in on-premises and cloud rollouts.
Contribute to application containerisation efforts, ideally with OpenShift or Kubernetes, or other container platforms.
Guide teams through the adoption of secure, scalable, and maintainable technology practices with a focus on RBAC, ABAC, and ReBAC models.
Utilise SQL and data processing techniques to inform technical decisions and feature design.

Key Skills:

Strong technical background in Java, with experience building and supporting high-throughput, production-grade systems at scale.
In-depth knowledge of cloud environments (especially AWS), and experience with hybrid deployment models.
Practical understanding of container orchestration and application deployment pipelines.
Direct experience with authorisation systems and policy enforcement, ideally using policy-as-code frameworks.
Understanding of authentication systems and how they integrate with broader technology estates (experience with Ping Identity is a plus).
Proven ability to take systems from development through to production support in enterprise environments.
Comfortable working with data—experience with SQL and data analysis to support engineering decisions is highly desirable.

What You’ll Bring:

A strong engineering foundation, with the ability to troubleshoot and resolve complex issues across platforms.
Experience working in cross-functional teams and managing multiple stakeholders with varying goals.
Ability to build trusting relationships with both technical and non-technical stakeholders, translating complex technical concepts into clear business value.
A collaborative and resilient approach, with a deep understanding of business context, technical architecture, and product strategy.
