Title and Summary Lead 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: - Serve as a technical lead for the Developer Workbench platform, driving engineering delivery and setting quality standards across the team. - Help define and evolve the technical direction of the Developer Workbench, contributing meaningfully to roadmap decisions and architecture choices. - Lead the integration and enablement of software engineering tools across the development lifecycle, ensuring reliability, scalability, and strong developer usability. - Own key areas of the "birthright and optional tooling" catalogue — driving version lifecycle decisions, conducting tool evaluations, and coordinating deprecation of redundant solutions. - Partner with product owners and platform teams to translate engineering priorities into well-scoped, executable technical plans. - Lead technical delivery of developer enablement capabilities — onboarding flows, self-service tooling, feedback integrations — and drive adoption across 11,500+ engineers. - Architect and deliver pre-provisioned onboarding environments that enable new hires to be productive within 30 minutes of day one. - Drive implementation of AI-augmented development capabilities including agentic coding tools, code assistants, and automated quality pipelines. - Define and instrument platform metrics that surface developer productivity, satisfaction, and platform health — and use that data to prioritize improvements. - Collaborate across engineering, security, and compliance teams to ensure implementations meet Mastercard's security and regulatory requirements. - Mentor and provide technical guidance to senior and mid-level engineers on the team. - Actively participate in the Software Engineering Guild, sharing technical expertise and promoting standard engineering patterns across the organization.

All About You: - Extensive background in software engineering, including demonstrated technical leadership on platform, developer tooling, or developer experience (DevEx) products. - Track record of leading technical delivery on complex, high-impact initiatives at enterprise scale — coordinating across engineers and workstreams without formal management authority. - 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 concrete platform improvements. - Experience designing and delivering pre-provisioned, standardized development environments at scale. - Solid understanding of cloud platforms (AWS, Azure, GCP), including infrastructure automation and cloud-native development patterns. - Ability to drive tool adoption through instrumentation, structured feedback mechanisms, and data-informed iteration. - Strong written and verbal communication skills — able to articulate technical tradeoffs clearly to both engineers and non-technical stakeholders. - Proficiency with software development productivity metrics (e.g., DORA metrics, onboarding time, tool adoption rates) and using data to guide technical decisions. - Self-driven and effective in ambiguous, fast-evolving technology environments, comfortable shaping direction without waiting for top-down clarity. - Strong understanding of Agile/Scrum methodologies and SDLC best practices from design through deployment. *Please note: This position requires candidates who are already located in the St.
