Senior Software Engineer-1
About The Position
Reactive Systems Architecture allows Application Teams to focus on the functional business requirements, leaving the task of addressing various non-functional requirements to the underlying framework, platform components and infrastructure. The functional business logic layer deals in messages, the delivery of which is an event that invokes some processing on that message. Specific to Mastercard / payment systems, these are typically financial messages. The non-functional requirements include, but are not limited to, security, traffic management, infrastructure-independent deployment, scalability, resiliency, high availability, consistent message delivery, delivery auditing, message delivery for failed/absent consumers, application lifecycle management, live/silent mode testing, stateful stream processing, strong consistency, observability, root cause detection and recovery. The Role What’s it all about and what we expect you to do day to day Own software delivery tasks (code development, test, deployment) at an application/software component level Able to troubleshoot and refactor existing code for exceptional code quality. Adopt new languages and architecture patterns needed for the work. Participate and contribute to the team’s agile process and decisions. Pull from backlog and deliver work after seeking guidance from experienced team members and in partnership with full scrum team. (Agile) Understands the big picture and end-to-end logical architecture of systems in ownership areas Provide feedback and suggestions on areas to improve Understands the use of Mastercard technology policies in everyday work Demonstrate active learning and sharing of software practices via Guild/Engineering community initiatives Influence the decisions made by the team. Assist peers and less experienced members. Influence the decisions made by the team. Assist in technical documentation of APIs and services being delivered.
