Principal Software Engineer

olve hard problems. We are we are skilled in security, design for operability and customer experience, privacy, and regulatory compliance and experts on our Technology Policies. We are the stewards of several of these policies including the Engineering Principles, Software Development Lifecycle Process, External Cloud Policy, and others as needed. We maintain these and other documents using an open contribution model: anyone can propose changes and we carefully review those and incorporate them into our documents. Finally, we maintain several libraries of code that help our engineering teams move faster, avoid re-inventing wheels, and eliminate undifferentiated heavy lifting. These may be built by A&T team members, curated from best practices in other Mastercard teams, or co-developed by A&T and engineers from the Guild.

The Role:
As an A&T Principal Software Engineer you will participate in numerous engagements with Mastercard engineering teams, as well as A&T deliverables such as patterns, frameworks, proof-of-concepts, incubated solutions, policy and standards updates, and shared libraries.
For some of these you will be spearheading the delivery personally or providing technical leadership to a group of contributors. For others you will be performing more of an advisory, mentoring role, coaching and providing feedback to help the engineering teams improve their designs, solve their problems, and become better engineers. You will spend a portion of your time coding as part of some of these internal activities and reviewing code on some of the engagements.
A&T assignments range broadly across all parts of the company, and all layers of the technology stack. On one assignment you may be participating in the Technical Due Diligence of a potential acquisition, on the next helping an engineering team for a mission critical payments application with their modernization roadmap, and on the one after that be down in the details of distributed computing platform services.
As part of your duties you will:
Work on complex enterprise-wide initiatives spanning multiple services/programs and drives resolution
Work with business/product owners to architect and deliver on new services to introduce new products and bundles
Drive the architectural design, including dependent services, service interactions, and policies
Take ownership to improve the customer experience of an entire set of services/applications sold as products or bundled services
Contribute and lead Guild initiatives by engaging and mentoring Engineers at all levels to improve the craftmanship of Software Engineering
Simplify and improve the cost/benefit of a function/service/architecture strategy
Apply judgment and experience to balance trade-offs between competing interests
Venture beyond comfort zone to take on assignments across different areas of Software Engineering
Take on organization-wide and public speaking engagements and publishes white papers and blogs on relevant and emerging technical topics
Consult across teams and across organization lines to identify synergies and reuse opportunities
Participate and contribute to Principal review architecture meetings and drive resolutions to enterprise-wide challenges and regulatory needs
Write recommendations for job promotions based on an unbiased view of one's accomplishments
Conduct technical interviews for hiring engineering staff and raising the performance bar
Identify and raise awareness to Silo-ed behaviors within the organization and teams

Understands internals of operating systems (Windows, Linux, Mainframe) to write interoperable and performant code.
Has skills to develop and evangelize on reference architecture and run principles to help teams adopt Engineering Principles from the start (poison pill, active/active/active, auto-scaling, self-healing, others)
Understands use cases for advanced design patterns (e.g., service-to-worker, MVC, API gateway, intercepting filter, dependency injection, lazy loading, all from gang of four) to implement efficient code
Understands and implements Application Programming Interface (API) standards and cataloging to drive API/service adoption and commercialization
Has skills to promote and coach teams on take on full stack development and facilitate end-to-end service ownership
Has skills to engage engineers across Technology organization to promote standard software patterns and reuse of common libraries and services
Has experience in leading and coaching teams to perform software planning and estimation for large scale complex programs
Has skills to drive trade-off discussions to set right development capacity based on value drivers (e.g., regulatory, security, new business, market parity, technical debt)
Has experience in design and execution of automation across multiple business areas and provides guidance on best methods and tools.
Has an expert understanding of DevOps best practices to guide developers and abstract application development from underlying hosting platforms and infrastructure
Performance engineering experience to ensure applications are built to scale, run, and perform for varying demands
Has skills to evaluate practices, metrics, and roles to continually optimize SDLC methodologies and automate processes to improve lead time and quality
Has skills to perform architecture and cost analysis for internal, hybrid, and public cloud environments
Has skills to succinctly articulate architecture patterns of complex systems, with business and technical implications, to executive and customer stakeholders
Has skills to define and drive advanced chaos and other operational testing practices to test points of failures, monitors, and system behaviors under adverse conditions (e.g., resource spikes, network congestion, component or infrastructure failure)
Has skills to implement advanced test set ups in production environment (e.g., A/B testing, canary releases, blue-green deployment, feature flags)

Corporate Security Responsibility

All activities involving access to Mastercard assets, information, and networks comes with an inherent risk to the organization and, therefore, it is expected that every person working for, or on behalf of, Mastercard is responsible for information security and must:

• Abide by Mastercard's security policies and practices;
• Ensure the confidentiality and integrity of the information being accessed;
• Report any suspected information security violation or breach, and
• Complete all periodic mandatory security trainings in accordance with Mastercard's guidelines.
