able to facilitate technical alignment across engineering teams and articulate complex concepts to non-engineering stakeholders. - Fluent with software development productivity metrics (e.g., DORA metrics, onboarding time, tool adoption rates) and experienced at using data to steer technical decisions collaboratively. - Self-driven and effective in ambiguous, fast-evolving technology environments - able to unblock yourself and others without waiting for full clarity. - Strong command of Agile/Scrum methodologies and SDLC best practices, with a track record of raising process maturity within engineering teams. ## Description Serve as a technical anchor on the team - setting the bar for engineering quality, driving architectural decisions, and providing hands-on guidance to fellow engineers across the platform. - Design, build, and maintain core components of the Developer Workbench platform across the full development lifecycle, while actively supporting teammates in doing the same. - Lead the technical direction and roadmap of the Developer Workbench, driving its evolution from a chargeback mechanism into a cohesive, productized developer experience - and bringing the engineering team along through clear technical reasoning and collaborative decision-making. - Own and advance the integration of software engineering tools across the development lifecycle, establishing patterns and practices the team can build on consistently. - Lead the governance of the "birthright and optional tooling" catalogue - driving version lifecycle management, tool evaluations, and deprecation of redundant solutions in close coordination with engineering stakeholders. - Partner with product owners, platform teams, and engineering stakeholders to align workbench capabilities with organization-wide engineering priorities, acting as a technical voice in cross-functional discussions. - Lead the design and delivery of developer enablement features - onboarding flows, self-service tooling, feedback integrations - and help the broader team understand and extend these systems effectively. - Architect and oversee the implementation of pre-provisioned onboarding environments that enable new hires to be productive within 30 minutes of day one. - Drive the adoption and advancement of AI-augmented development capabilities including agentic coding tools, code assistants, and automated quality pipelines - acting as a technical authority and enabler for the team. - Define and champion meaningful instrumentation and metrics that surface developer productivity, satisfaction, and platform health across the organization. - Engage across engineering, security, and compliance teams to ensure tooling implementations meet Mastercard's security and regulatory requirements, and help teammates navigate those constraints effectively. - Actively contribute to and help lead the Software Engineering Guild - sharing deep technical expertise, elevating engineering standards, and mentoring engineers across the organization., 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;
