What you'll do

Requirement And Scoping Analysis: Requires knowledge of: Traceability matrix; Risk analysis methodologies; Cost Analysis; Business objectives; Classification of requirements; User stories To explore relevant products/solutions from an existing repertoire, that 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 (For example - Functional/Non-Functional, Derived/Imposed/Emergent etc.). 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).

Conduct scoping of epics user stories within span decide on tradeoffs under guidance as needed.

Solution Design: Requires knowledge of: Software architecture; Distributed systems; Scalability; Design patterns; Disaster Recovery; Tech Stacks; Minimum Viable Product- MVP; Non-Functional Requirements; Telemetry. To assist in creation of simple, modular, extensible and functional design for the product/solution in adherence to the requirements. Evaluate trade-offs while designing across multiple components in a product based on the business requirements. Convert HLD to create detailed design using mock screens, pseudo codes and detailed functional logic of the modules for specific modules / components of a product. Understand nuances of designing for disaster recovery. Design and create MVP to clarify requirements and design and uncover risks. Independently refine the MVP design for early defects and revised customer requirements.

Coding: Requires knowledge of: Coding standards and guidelines; Coding languages (E.g. JavaScript, Python, C etc.), frameworks(E.g. ActiveX, .Net, Cocoa, Android application framework etc.), tools(E.g. Linx, Embold etc.) and Platforms (E.g. Microsoft Azure, AWS , Apple IOS etc.); Quality, Safety and Security (PCI etc) standards; Emerging tools and technologies; Telemetry. To select appropriate frameworks (E.g. ActiveX, .Net, Cocoa, Android application framework etc.), platforms(Microsoft Azure, AWS , Apple IOS etc.), and environments for software coding/configuration and scripting (Applicable to IC & PL). Guide the team on coding patterns, languages and frameworks in line with evolving trends in the industry (Ex: reactive vs. imperative etc.) and drive scalability and security (Applicable to IC & PL). Drive Implementation of telemetry features by determining data/metrics requirement within the domain (Applicable to IC & PL). Support ad-hoc reviews of software code to ensure baseline mitigations for known risks.(Applicable only to IC). Create/configure minimalistic code for entire product/system and ensure the product is meeting business requirements, non-functional requirements, low-maintainability, high-availability and high-scalability needs (Applicable only to IC). Oversee the codes executed by team in line with specified technical/business requirements (Applicable only to IC). Arrange project requirements in programming sequence by analyzing requirements (Applicable only to IC). Drive creation of scripts for automation of repetitive and routine tasks in CI/CD (Continuous Integration/Continuous Delivery), Testing or any other process across the domain (Applicable only to IC).

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. To translate customer requirements into test strategy (Applicable to IC & PL). Determine the testing tools (E.g. - Automation - Selenium, Agile - Jira, Mobile - Eggplant etc.) , domains, environments and test types to be employed to achieve testing objectives (Applicable to IC & PL). Select, introduce and implement various tools for testing (Applicable to IC & PL). Identify scope and method of testing for each requirement (Applicable only for IC). Ensure that the test cases cover all the test scenarios (E.g. for functionality, performance, security, integration, data migration and accessibility )for the product/solution requirements (Applicable only for IC). Drive execution of test cases to test the code and detect errors and defects for the entire product (Applicable only for IC). Ensure code coverage for relevant functional area.

Program Monitoring: Requires knowledge of: Program metrics; Program Reporting, logging tools and processes; Continuous Integration/Continuous Deployment (CICD) To Monitor and Evaluate the progress of the projects against approved milestones and timelines. Provide inputs to relevant stakeholders regarding schedule progress, health, issues/risks, and key dependencies. Provide inputs to relevant stakeholder for creation of project plans. Ensure adherence to the CICD process as per identified schedule.

Defect Management and Troubleshooting: Requires knowledge of: Defect life-cycle process, defect tracking tools and methodologies; Defect reporting; Regression testing; Root cause analysis; Root cause corrective action. To conduct root cause analysis (RCA) and root cause corrective action (RCCA) to identify the origin of defects/ performance gaps and prevent them from recurring. Track registered issues for the product/solution and prioritize them for resolution. Measure usability of the product/solution as per customer/business requirement after defect fixing and plugging test gaps. Analyze the issues and plan a series of steps which potentially includes reconfiguration, integration, removal or addition of application components to enhance the application's functionality, usability and security.

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.
