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.

• Solid understanding of cloud platforms (AWS, Azure, GCP), including infrastructure automation and cloud-native development patterns.
• Ability to contribute to tool adoption through instrumentation, metrics, and feedback mechanisms.
• Strong written and verbal communication skills with the ability to collaborate effectively across engineering and cross-functional

teams.

• Familiarity with software development productivity metrics (e.g., DORA metrics, onboarding time, tool adoption rates) and using data to

inform technical decisions.

• Self-driven and comfortable operating in ambiguous, fast-evolving technology environments.
• Strong understanding of Agile/Scrum methodologies and SDLC best practices from design through deployment.
