Join us as an AWS & Java Integration Engineer at Barclays, where you will spearhead the evolution of our infrastructure and deployment pipelines, driving innovation and operational excellence. You will harness cutting-edge technology to build and manage robust, scalable and secure infrastructure, ensuring seamless delivery of our digital solutions. To be successful as an AWS & Java Integration Engineer, you should have experience with: Java Development: Strong proficiency in Java, with experience in building enterprise-grade applications or microservices (ideally using frameworks like Spring Boot). Deep understanding of object-oriented design, design patterns, and data structures for robust backend development. AWS Cloud Expertise: Hands-on experience deploying and operating services on AWS. This includes building serverless applications with AWS Lambda, designing event-driven architectures, and utilising AWS services for integration tasks (API Gateway, SQS/SNS, etc.). Familiarity with AWS IAM (Identity and Access Management) for secure service access and role permissions is crucial. Cloud-Native & Microservices: Knowledge of cloud-native design principles and microservice architecture. Experience creating RESTful APIs, working with containers (Docker) or orchestration (Kubernetes/ECS) for scalable services, and using infrastructure-as-code tools (CloudFormation or Terraform) to manage AWS resources. Ability to implement resilient, fault-tolerant integrations (circuit breakers, retries, monitoring). System Integration & IDP: Demonstrated ability to integrate disparate systems and data sources. Experience with enterprise integration patterns (messaging systems, ETL pipelines, SOAP/RESTful services) is important. Additionally, familiarity with Intelligent Document Processing (IDP) solutions on AWS is a plus – for example, understanding how to use services like Amazon Textract or Amazon Bedrock to automate document data extraction and processing. This exposure will help in projects where the bank leverages AI-driven document processing or generative AI services. Security & Best Practices: Solid grasp of security practices in development and AWS. Capable of implementing authentication/authorisation, encryption, and secure API design (OAuth, JWTs) in line with banking security standards. Knowledge of logging, monitoring, and testing frameworks (JUnit for Java, and AWS CloudWatch or X-Ray for monitoring) to ensure the integrations are reliable and maintainable. Some other highly valued skills may include: Exposure to AI/ML services or working alongside AI teams is beneficial. This could mean understanding how to integrate machine learning models or AI APIs into applications (for instance, calling a predictive model's API or incorporating a recommendation engine output into a workflow). Familiarity with AWS's AI services like Amazon Bedrock (for deploying or consuming foundation models) or Amazon SageMaker would be an advantage. While not a primary responsibility, this knowledge helps in projects where backend systems interface with AI components (such as feeding data to ML models or handling responses from an AI service). Domain Knowledge: Experience in the financial services domain is a plus. Understanding banking systems, payment processing, or documents (like loan forms, KYC documents) can help in designing integrations. This domain context will inform better decisions around error handling, data consistency, and compliance when connecting systems. 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. The role is based out of Pune. Our Work Experience is the combination of everything that's unique about us: our culture, our core values, our company meetings, our commitment to sustainability, our recognition programs, but most importantly, it's our people.
