About the Role

As a Senior Java Software Engineer, you will make an impact by designing and delivering robust, scalable web applications and microservices-based solutions that meet the highest standards of quality, security, and performance. You will be a valued member of our engineering team and work collaboratively with developers, architects, graphic designers, and cross-functional stakeholders to design, launch, and continuously improve innovative digital products.

In This Role, You Will:

• Develop and implement tasks and components of projects in line with client requirements, writing zero-defect code and comprehensive unit test cases to ensure first-time-right delivery within defined timelines, security, and performance guidelines.
• Design the overall architecture of web applications, applying microservices principles and established design patterns to deliver scalable, maintainable solutions.
• Develop and maintain business layer coding, interface development, service development, and stored procedures, raising issues proactively and seeking peer review to continuously improve output quality.
• Write and execute unit test cases, capture and resolve defects, and support integration and automation testing throughout development, SIT, UAT, and warranty phases.
• Understand, interpret, and clarify both functional and technical requirements; provide effort and timeline estimates for assigned tasks; and support proof-of-concept development with relevant stakeholders.
• Identify and highlight potential risks to technical leads in a timely manner; support the integration of components; maintain traceability matrices; and adhere to SCM policies, process tools, and Quality Management System standards.
• Collaborate with graphic designers to convert designs into polished visual elements, and contribute to the implementation of security and data protection measures across the application.
• Contribute to the development and maintenance of knowledge assets, including user manuals, installation scripts, and online documentation; actively contribute to and reuse assets from the team repository.
• Provide ideas for process optimisation and value-add initiatives, sharing them with relevant stakeholders while promoting adherence to tools such as Cognizant 2.0 and established IDE standards.
• Improve core technical skills on an ongoing basis, keeping pace with evolving technology landscapes including Gen AI tooling, cloud platforms, and DevOps practices.
