## Description

Our Purpose Mastercard powers economies and empowers people in 200+ countries and territories worldwide. Together with our customers, we’re helping build a sustainable economy where everyone can prosper. We support a wide range of digital payments choices, making transactions secure, simple, smart and accessible. Our technology and innovation, partnerships and networks combine to deliver a unique set of products and services that help people, businesses and governments realize their greatest potential. Title and Summary Senior Software Engineer Overview: The Mastercard Developer Workbench, part of the MSBX (Mastercard Software Builder Experience) division, is evolving from a cost-allocation construct into a unified, developer-centric platform. With over 11,500 software engineers across the organization, Mastercard is investing in a dedicated product team to deliver an integrated, end-to-end developer experience. The Developer Workbench brings together five core MSBX products — BuildersHub, DevFlow, TestFlow, DevInsights, and Cloud DevEx — alongside cross-cutting tools including GitHub Copilot, Claude Code, and Docker Desktop. This is a rare opportunity to shape the future of how engineers at one of the world's leading technology companies build, test, and ship software. About the Role: - Design, build, and maintain core components of the Developer Workbench platform across the full development lifecycle. - Contribute to the technical direction and roadmap of the Developer Workbench, helping evolve it from a chargeback mechanism into a cohesive, productized developer experience. - Drive the integration and enablement of software engineering tools across the development lifecycle, with a focus on usability and reliability. - Contribute to the governance of the "birthright and optional tooling" catalogue — supporting version lifecycle management, tool evaluations, and deprecation of redundant solutions. - Collaborate with product owners, platform teams, and engineering stakeholders to deliver workbench capabilities that align with organization-wide engineering priorities. - Build and improve developer enablement features — onboarding flows, self-service tooling, feedback integrations — to maximize the value of deployed tools across 11,500+ engineers. - Design and implement pre-provisioned onboarding environments that enable new hires to be productive within 30 minutes of day one. - Implement and advance AI-augmented development capabilities including agentic coding tools, code assistants, and automated quality pipelines. - Instrument the platform with meaningful metrics that surface developer productivity, satisfaction, and platform health. - Engage across engineering, security, and compliance teams to ensure tooling implementations meet Mastercard's security and regulatory requirements. - Actively participate in the Software Engineering Guild, sharing technical expertise and promoting standard engineering patterns across the organization. All About You: - Strong background in software engineering, ideally including work on platform engineering, developer tooling, or developer experience (DevEx) products. - Hands-on experience building and operating developer platforms or internal tooling at enterprise scale. - Deep familiarity with the modern developer tooling ecosystem, including: - AI coding assistants: GitHub Copilot, Claude Code, or similar - Containerization and desktop dev environments: Docker Desktop, Kubernetes, DevContainers - CI/CD and pipeline tooling: GitHub Actions, Jenkins, ArgoCD, or similar - Developer portals and inner-source platforms: Backstage, or similar - Experience working with AI-powered developer tools in a regulated enterprise environment, including an understanding of policy compliance, access controls, and responsible AI usage. - Strong understanding of developer experience (DevEx) principles and the ability to translate developer pain points into platform improvements. - Experience designing and
