Senior Software Engineer

Senior Software Engineer

Requirements

• Windows Server Admin, PowerShell, CIS Benchmark experience is preferred
• Ability to write secure code in multiple languages (e.g., Java, Python, Golang, C#) and familiar with secure coding standards (e.g., OWASP, CWE, SEI CERT) and vulnerability management
• Understanding of the basic engineering principles used in building and running mission critical software capabilities (security, customer experience, testing, operability, simplification, service-oriented architecture)
• Ability to perform debugging and troubleshooting to analyze core, heap, thread dumps and remove coding errors
• Understanding and implementing standard branching (e.g., Gitflow) and peer review practices
• Skills in test driven and behavior driven development (TDD and BDD) to build just enough code and collaborate on the desired functionality
• Understanding use cases for advanced design patterns (e.g., service-to-worker, MVC, API gateway, intercepting filter, dependency injection, lazy loading, all from the gang of four) to implement efficient code
• Understanding and implementing Application Programming Interface (API) standards and cataloging to drive API/service adoption and commercialization
• Skills to author test code with lots of smaller tests followed by few contract tests at service level and fewer journey tests at the integration level (Test Pyramid concept)
• Ability to apply tools (e.g., Sonar, Zally, Checkmarx) and techniques to scan and measure code quality and anti-patterns as part of development activity
• Skills to collaborate with team and business stakeholders to estimate requirements (e.g., story pointing) and prioritize based on business value
• Skills to elaborate and estimate non-functional requirements, including security (e.g., data protection, authentication, authorization), regulatory, and performance (SLAs, throughput, transactions per second)
• Skills to orchestrate release workflows and pipelines, and apply standardized pipelines via APIs to achieve CI and CD using industry standard tools (e.g., Jenkins, XL Release, others)
• Skills to understand, report, and optimize delivery metrics to continuously improve upon them (e.g., velocity, throughput, lead time, defect leakage, burndown)
• Skills to document and drive definition-of-done for requirements to meet both business and operational needs
• Understanding how to build robust tests to minimize defect leakage by performing regression, performance, deployment verification, and release testing
• Skills to conduct product demos and co-ordinate with product owners to drive product acceptance signoffs
• Skills to understand customer journeys and ensure a Mastercard good experience by continuously reducing Mean time to mitigate (MTTM) for incidents and ensuring high availability (99.95% as a starting point)

Responsibilities

• Participate in team prioritization discussions with Product/Business stakeholders
• Estimate and own delivery tasks (design, dev, test, deployment, configuration, documentation) to meet the business requirements
• Automate build, operate, and run aspects of software
• Drive code/design/process trade-off discussions within their team when required
• Report status and manage risks within their primary application/service
• Drive integration of services focusing on customer journey and experience
• Perform demos/acceptance discussions in interacting with Product owners
• Understand operational and engineering experience, actively work to improve experience and metrics in ownership area
• Develop complete understanding of end-to-end technical architecture and dependency systems
• Drive adoption of technology standards and opinionated frameworks, and review coding, test, and automation work of team members
• Identify opportunities to improve an overall process and trim waste
• Share and seek knowledge within their Guild/Program to drive reuse of patterns/libraries/practices and enhance productivity
• Security mindset with least privilege experience to support access provisioning and modeling
• Support in automation, domain separation strategies and business recovery initiatives
