2.Possess strong understanding of message-driven and API-based architectures, including asynchronous communication patterns, enterprise integration strategies, and best practices across open systems and NonStop platforms.
3.Maintain familiarity with relevant ISO standards related to software quality, security, and financial/payment systems, ensuring alignment with regulatory and audit requirements.
4.Proficient in commonly used data exchange formats such as XML, JSON, and YAML, supporting interoperability across heterogeneous systems.
5.Exhibit strong analytical and problem-solving skills, with the ability to translate complex business requirements into scalable, resilient, and maintainable technical solutions across both modern and legacy platforms.
6.Hands-on experience with Git, Bitbucket, or equivalent version control systems, including effective use of branching strategies, code reviews, and collaborative development practices.
7.Working knowledge of code quality and security scanning tools, including SonarQube, Fortify, and similar static analysis platforms, ensuring adherence to secure coding standards.
8.Experience with microservices or serverless architectures in cloud environments (preferably AWS), enabling scalable and resilient system design.
9.Strong understanding of security principles, including encryption, hashing, secure key management, and secure communication protocols across distributed systems.
10.Working knowledge of HP NonStop technologies, including exposure to TAL programming, TACL scripting, Pathway, and NonStop system utilities, with an understanding of operational processes such as logging, monitoring, and batch processing.
11.Strong collaboration skills with the ability to engage effectively with cross-functional teams, including business, operations, and technical stakeholders.
12.Excellent written and verbal communication skills, with the ability to produce clear technical documentation, troubleshooting guides, and knowledge base articles.
13.Strong interpersonal abilities with effective time management and prioritization skills to operate efficiently in dynamic and high-pressure environments.
14.Solid hands-on experience across the Software Development Lifecycle (SDLC), including unit testing, integration testing, and CI/CD-driven delivery practices, ensuring quality and reliability of software releases.

Education and Experience:
 
Minimum Bachelor's degree in Computer Science, Information Technology, or a related field.
At least 8 to 10 years of hands-on experience in Java and HP Nonstop Development
Strong proficiency in Java 8, 17 or higher, and related frameworks (e.g. Spring Framework, Spring Boot, Spring Security, Spring Integration) for backend development.
Hands-on with AWS would be an added advantage.
