Title and Summary

Software Engineer II

Overview:
The Infrastructure Design Engineering Automation (IDEA) team at Mastercard is looking for a Software Engineer II with a focus on front-end development to join as a hands-on individual contributor.
In this role, you’ll work on well-defined problems while contributing to scalable, user-focused solutions. You’ll participate in design discussions, collaborate across teams, and take ownership of delivering high-quality, reliable code.
The IDEA team builds internal tools that help infrastructure and platform teams do their work faster and more consistently. Our tools support how technical designs are created, reviewed, and turned into usable outputs for other teams and automation.
One of our main applications is RAA, a web‑based tool used to create and manage technical architecture designs. We focus on usability, reliability, and gradual automation, working closely with engineers, architects, and platform teams.

This is a hybrid position based in O’Fallon, MO requiring three days per week onsite.

Role:

Contribute to the development of front-end features using modern frameworks.
Improve existing code for clarity, performance, and maintainability.
Troubleshoot issues and support production systems as needed.
Assist in building responsive, user-friendly web applications.
Support testing, debugging, and troubleshooting of applications.
Participate in code reviews and contribute to technical design discussions.
Write unit tests and maintain clear, concise documentation.
Collaborate with cross-functional teams to understand requirements and deliver solutions.
Continuously learn and apply new technologies and development techniques.

All About You:

Experience in software engineering or application development, with a focus on front-end technologies
Foundational knowledge of JavaScript, TypeScript, and React.
Basic understanding of web development concepts (HTML, CSS, APIs)
Familiarity with version control systems (e.g., Git)
Familiarity with Agile methodologies (Scrum or Kanban) and iterative delivery models
Comfortable working across the full software development lifecycle (build, test, release, support)
Experience with modern development tools (version control, CI/CD pipelines, code reviews, issue tracking systems)
Exposure to professional web application development is preferred.
Strong problem-solving skills and a passion for building user-centric solutions.
Self-motivated, proactive, and able to work independently in a collaborative environment.
Strong communication skills, with the ability to explain technical concepts clearly.
Bachelor degree in Computer Science, Software Engineering, Information Technology, Mathematics, or a related field. Equivalent practical experience may also be considered.

This role is not eligible for Mastercard’s work authorization sponsorship. As such, candidates must be eligible to work in the United States, now as well as in the future, without employer sponsorship.
