Description

This is a hands-on Lead Engineer role focused on building backend and full-stack capabilities for Mastercard's next-generation Decision Management Platform.

You will own technical areas end to end, write code, shape architecture, mentor engineers, and turn ambiguous goals into reliable services, APIs, workflow tools, and user-facing experiences.

Key Responsibilities:

  • Own meaningful backend and full-stack capabilities from problem definition through design, implementation, testing, deployment, and production support.
  • Design and build scalable services, APIs, workflow tooling, frontend experiences, and integrations.
  • Set technical direction, make pragmatic architecture decisions, and align engineers around maintainable solutions.
  • Use design reviews, code reviews, and hands-on coaching to raise engineering quality and reduce complexity.
  • Write code, build prototypes, and use AI coding tools to improve speed, quality, and team effectiveness.
  • Work closely with product, engineering, and senior stakeholders to turn ambiguous goals into working software and measurable outcomes.

What We're Looking For:

  • You lead through delivery. You have shipped meaningful backend, full-stack, or product-facing capabilities in complex production systems.
  • You think end to end. You connect user experience, APIs, backend design, data flows, operations, and business outcomes.
  • You influence by doing the work. You guide technical direction through judgment, clear communication, and hands-on credibility.
  • You care about quality. Testing, observability, security, clean interfaces, and maintainability are part of how you build.
  • You are adaptable. You are comfortable with ambiguity, changing priorities, and small, fast-moving teams.

Relevant Experience:

  • Strong hands-on software engineering experience building backend services, APIs, full-stack applications, or complex production systems.
  • Experience owning technical areas end to end, including design, implementation, testing, deployment, and production support.
  • Strong fundamentals in software design, architecture, API design, data modeling, testing, code review, secure coding, performance, and troubleshooting.
  • Experience mentoring engineers and influencing technical direction through design reviews, code reviews, and clear communication.
  • Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent experience.

Benefits:

  • Insurance (including medical, prescription drug, dental, vision, disability, life insurance)
  • Flexible spending account and health savings account
  • Paid leaves (including 16 weeks of new parent leave and up to 20 days of bereavement leave)
  • 80 hours of Paid Sick and Safe Time
  • 25 days of vacation time and 5 personal days
