Senior Software Engineer

We are seeking a Senior Software Engineer to join the Resilience Operations team, working alongside CTO Platform Engineering. In this role, you will design, develop, and maintain cyber resilience and recovery tooling that enables teams across Barclays to autonomously manage protection and recovery operations.

You'll work on a distributed microservices platform that orchestrates complex workflows across multi-infrastructure environments, integrates with enterprise governance systems, and handles real-time event streaming and state management. You will partner with infrastructure teams, security teams, and application owners to deliver solutions that reduce recovery times, improve operational efficiency, and strengthen the bank's overall resilience posture.

As a senior engineer, you'll own key architectural decisions, mentor team members, and contribute to evolving our platform's scalability, reliability, and security.

• Adherence to secure coding practices to mitigate vulnerabilities, protect sensitive data, and ensure secure software solutions.
• Implementation of effective unit testing practices to ensure proper code design, readability, and reliability.
