All About You and What you need to bring

Has ability to write secure code in three or more languages (e.g., Java, .NET, JavaScript, SQL). Familiar with secure coding standards (e.g., OWASP, CWE, SEI CERT) and vulnerability management. Infrastructure as code and cloud first software development knowledge experience preferred. Understands and implements standard branching (e.g., Gitflow) and peer review practices. Move the team towards trunk based development. Apply tools (e.g., Sonar, Zally, Checkmarx) and techniques to scan and measure code quality and anti-patterns as part of development activity. Has skills in test driven and behavior driven development (TDD and BDD) to build just enough code and collaborate on the desired functionality. Ability to keep the full testing pyramid healthy - Has 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. Understands the use of basic design patterns (e.g., factory, adaptor, singleton, composite, observer, strategy, inversion of control). Understands 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. Understands and implements Application Programming Interface (API) standards and cataloging to drive API/service adoption and commercialization and effort estimation. Experienced in agile and modern SDLC practices (Scrum/Kanban/Continuous Delivery/DevOps/Quality engineering) and the delivery situations they are used for. Has skills to elaborate and estimate non-functional requirements, including security (e.g., data protection, authentication, authorization), regulatory, and performance (SLAs, throughput, transactions per second). Has 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, AWS/Azure pipelines, XL Release, others). Familiar with different application patterns to implement different types of business processes (e.g., APIs, event-driven-services, batch-services, web-applications, big data). Experience in Continuous Integration (CI) and Delivery (CD) concepts, and capabilities to support automation, pipelines, virtualization, and containerization. Has ability to write code (in languages such as Java, Python, Ruby, Bash, Perl, Groovy) to build automation tasks that are repeatable and efficient. Able to perform debugging and troubleshooting to analyze core, heap, thread dumps and remove coding errors. Has skills to conduct product demos and co-ordinate with product owners to drive product acceptance signoffs. Understands 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).

We can still look at Java Full Stack but must have strong back end experience, preference would be a Backend Developer

2 Rounds of Interviews - The interviews will involve a whiteboarding/coding exercise

100% Remote is Ok – Ok to sit in different Time Zone but need to be ok to work CST (Team in ST Louis) 9am-5pm CST (If someone is willing to work onsite that is fine, but no preference will be given to them. It all depends on the skillset)
