Senior Software Engineer

Performs solution design, including software architecture; distributed systems; scalability; design patterns; disaster recovery; tech stacks; product (MVP); non-functional requirements; and Telemetry. in design of solutions such that the processes/applications work in tandem for specific components/modules of a product. Evaluates trade-offs while designing a based on business requirements. in conversion of HLD (High Level Design) to create detailed design using mock screens, pseudo codes and detailed functional logic of the modules for specific modules / components of a product. Performs requirement and scoping analysis, including traceability matrix; risk analysis methodologies; cost analysis; business ; classification of requirements; user stories to explore relevant products/solutions from an existing repertoire to address business/technical needs. Assesses gaps/updates/modifications between the customer/business expectations and existing product/solutions (in case of agile , for the iteration). Classifies the requirements into applicable types (i.e., functional/non-functional, derived/imposed/emergent, etc.). Anticipates solution risks/issues during requirements gathering phase, informs relevant stakeholders and recommends corrective steps. Contributes to the creation of user stories for component/application/complex (for Agile Methodology). Reviews coding standards and guidelines; coding languages (including JavaScript, Python, C#, etc.), frameworks (including ActiveX, , Cocoa, Android application framework, etc.), tools (Monday.com, Linx, , etc.) and Platforms (Microsoft Azure, AWS, Apple IOS, etc.); Quality, Safety and Security (PCI, etc.) standards; utilizes emerging tools and technologies, including Telemetry, to create/configure minimalistic code for entire component/application and ensure the components are meeting business/technical requirements, non-functional requirements, low-maintainability, high-availability, and high-scalability needs. in the selection of appropriate languages , etc.) for software coding/configuration. Builds scripts for automation of repetitive and routine tasks in CI/CD (Continuous Integration/Continuous Delivery), testing or any other process (as applicable). Implements telemetry features as independently. Ensures security policy requirements are properly applied to components/application during code development/configuration. Performs testing, including test case test tools (Automation - Selenium, Agile - Jira, Mobile - Eggplant, etc.); test root cause analysis. Maps customer requirements to test and creates test cases for the component/module. Executes test cases to test the code and detect errors and defects for the entire . Executes different types of testing using appropriate testing tools based on the testing needs.
