ASF programs thrive in a culture of innovation and are constantly seeking individuals who can bring creative ideas to solve complex problems, both technical and procedural at the team and portfolio levels.

Responsibilities:

+ Serve as a critical Backend Java Developer within an Agile Scrum team, essential for powering a large-scale enterprise modernization initiative.

+ Designing, developing, and implementing robust, scalable, and secure API services and backend capabilities that will directly support our modern Angular frontend, as it migrates hundreds of screens from Dojo and Salesforce systems.

+ Design, develop, and implement highly performant and secure RESTful APIs and microservices using Spring Boot, acting as the foundation for the new modern Angular application.

+ Collaborate closely with front-end Angular developers to define API contracts, ensure seamless data flow, and optimize overall application performance and responsiveness.

+ Actively participate in all Agile ceremonies including sprint planning, daily stand-ups, sprint reviews, and retrospectives, providing technical insights and estimations specific to backend development, API integration, and database solutions.

+ Contribute to the continuous improvement of backend architecture, development processes, and coding standards, ensuring high quality, maintainability, and security across all services.

+ Analyze complex project-related problems, especially concerning data models and API interactions, creating innovative and efficient solutions.

+ Integrate with existing legacy systems (e.g., Salesforce back-end, Dojo data sources) as needed during the design / develop / migration phases, including potential data extraction, transformation, and loading (ETL) or service orchestration.

+ Provide mentorship to junior team members on Java, Spring Boot, microservices architecture, and database best practices.
