Software Chaos Engineer

Join us as a Software Chaos Engineer at Barclays, where you'll spearhead the evolution of our digital landscape, driving innovation and excellence. You'll harness cutting-edge technology to revolutionize our digital offerings, ensuring unapparelled customer experiences. The ideal candidate will have deep expertise in cloud-native technologies, distributed streaming platforms, Kubernetes orchestration, and multi-region architecture patterns.

To be a successful Software Chaos Engineer, you should have experience with:

• Design and execute hypothesis‑driven chaos engineering experiments using tools such as Gremlin and/or Harness Chaos Engineering, across Kubernetes, cloud, and application layers.
• Perform controlled fault‑injection scenarios, including infrastructure, network, application, and platform failures, to validate system availability, recovery behavior, and operational resilience.
• Validate system resilience and dependency behavior through infrastructure, network, and downstream service failure scenarios, identifying systemic weaknesses and recovery gaps.
• Design, develop, and maintain chaos test scenarios, ensuring repeatability, observability, and measurable outcomes aligned to resilience objectives.
• Implement PACT consumer‑driven contract testing for microservices and API‑based systems to reduce integration risk and improve deployment confidence.
• Design, maintain, and verify consumer and provider contracts, ensuring backward compatibility and safe evolution of services.
• Embed contract testing and chaos experiments into CI/CD pipelines as quality and resilience gates, preventing regressions from reaching higher environments.
•  Develop and maintain automation frameworks and utilities using Python to support resilience testing, test orchestration, and reporting.
• Analyse test outcomes, identify failure patterns, and work closely with engineering teams to remediate issues and improve platform reliability.
• Apply strong working knowledge of Git, DevOps tooling, Kubernetes, and public cloud platforms (AWS preferred) to support scalable and automated resilience testing.
• Deliver software using Agile methodologies, actively participating in sprint planning, reviews, retrospectives, and continuous improvement.
• Hands‑on experience with: Docker Desktop for local containerized development, IntelliJ IDEA or equivalent enterprise IDEs and Secure source control, branching strategies, and automated quality gates.
• Demonstrates strong familiarity with Event‑Driven Architecture (EDA) concepts and patterns, with exposure to industry‑standard messaging and streaming platforms, supporting solutions designed for high throughput, low latency, and resilience.
• Drive a test‑first, quality‑driven engineering culture with hands‑on experience.
• .Contract Testing (PACT) for consumer‑provider assurance.
• Unit Testing (JUnit) and integration testing.
• Performance & load testing (JMeter).
• Mutation testing to validate test effectiveness.
• Ensure test coverage and automation are embedded into CI/CD pipelines, not treated as post‑delivery activities.

Some other highly valued skills may include:

• Contribute as a hands‑on Individual Contributor Engineer (ICE), owning end‑to‑end delivery of chaos and contract testing capabilities with minimal supervision.
• Work effectively within Agile/Scrum delivery models, using Jira for backlog management, delivery tracking, and sprint execution.
• Apply strong analytical and troubleshooting skills to diagnose and resolve complex issues in distributed, event‑driven systems.
• Demonstrate excellent verbal and written communication, producing clear architecture designs, decision records, and technical documentation.
• Collaborate closely with cross‑functional teams (engineering, DevOps, security, architecture) to deliver integrated, enterprise‑ready solutions.
• Exhibit strong ownership, self‑drive, and innovation mindset, staying current with cloud‑native technologies and modern engineering best practices.

You may be assessed on key critical skills relevant for success in role, such as risk and controls, change and transformation, business acumen, strategic thinking and digital and technology, as well as job-specific technical skills.

This role is based out of Bengaluru.
