Senior Software Engineer - Java

Requirement and scoping analysis requires knowledge of risk analysis methodologies, cost analysis, business objectives, classification of requirements, domain knowledge, user stories concepts, functional non-functional requirements, scoping and estimation. To explore relevant products/solutions from an existing repertoire which can address business/technical needs, assess gaps, updates, modifications between the customer/business expectations and the existing product/solutions in case of agile methodology for the iteration, classify the requirements into applicable types, anticipate the solution risks issues during requirements gathering phase, inform relevant stakeholders and recommend corrective steps, contribute to the creation of user stories for component/application complex for agile methodology solution design.

Solution design requires knowledge of software architecture, distributed systems, scalability, design patterns, disaster recovery tech stacks, minimum viable product (MVP), non-functional requirements, detailed design. To assist in design of solutions such that the processes applications work in tandem for specific components/modules of a product, evaluate tradeoffs while designing a component based on the business requirements, assist 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.

Coding requires knowledge of coding standards and guidelines, coding languages (e.g., JavaScript, Python, C, etc.), frameworks (e.g., ActiveXNet, Cocoa, Android application framework, etc.), tools (e.g., Monday.com, Linx, Embold, etc.), and platforms (e.g., Microsoft Azure, Apple iOS, etc.) quality, safety, and security, PCI, etc. standards, emerging tools and technologies, telemetry, CI/CD code management tools, SDLC secure SDL frameworks and tools. To create/configure simple testable maintainable code for the entire component/application and ensure the components are meeting business/technical requirements, non-functional requirements, low-maintainability, high-availability, and high-scalability needs, assist in the selection of appropriate languages, development standards, and tools for software coding/configuration, take initiative to learn the fundamentals of different coding languages and frameworks that would be useful for future scope of work, build scripts for automation of repetitive and routine tasks in CI/CD Continuous Integration/Continuous Delivery, testing, or any other process as applicable, implement telemetry features as required independently, ensure security policy requirements are properly applied to components/application during code development/configuration.

Testing requires knowledge of test case preparation, test objectives, test strategy, test types, test tools (e.g., Automation, Selenium, Agile, Jira, Mobile, Eggplant, etc.), test environment, root cause analysis, code coverage, test coverage. To map the customer requirements into test objectives, identify and create test cases for the component/module, execute test cases to test the code and detect errors and defects for the entire component, execute distinct types of testing using appropriate testing tools based on the testing needs, program monitoring requires knowledge of program metrics, program reporting, logging tools and processes, continuous integration/continuous deployment (CI/CD), defect management and troubleshooting requires knowledge of defect lifecycle process, defect tracking tools and methodologies, defect reporting, regression testing, root cause analysis, root cause corrective action, to track and analyze defects for the component module and carry out regression testing to fix defects in all instances of code changes, analyze defects from past projects/solutions to avoid recurrence of similar defects, troubleshoot performance and availability bottlenecks for the application.

DevOps orientation requires knowledge of different operating systems, software maintenance tools and techniques, application monitoring tools and techniques, debugging tools, mock screen, pseudocodes, reverse engineering, traceability matrix, system performance, security, integration, data migration and accessibility, design methodologies, telemetry. To conduct complex maintenance procedures for applications independently, monitor and evaluate the performance of the application by tracking and analyzing appropriate metrics, perform maintenance corrective adaptive perfective and reengineering activities, analyze application logs, maintenance activity data, performance data and provide analysis, evaluate change requests to identify those which are valid and feasible, demonstrates up-to-date expertise and applies this to the development execution and improvement of action plans by providing expert advice and guidance to others in the application of information and best practices supporting and aligning efforts to meet customer and business needs and building commitment for perspectives and rationales, provides and supports the implementation of business solutions by building relationships and partnerships with key stakeholders identifying business needs determining and carrying out necessary processes and practices monitoring progress and results recognizing and capitalizing on improvement opportunities and adapting to competing demands organizational changes and new responsibilities models compliance with company policies and procedures and supports company mission values and standards of ethics and integrity by incorporating these into the development and implementation of business plans using the Open Door Policy and demonstrating and assisting others with how to apply these in executing business processes and practices.
