• Develop software that meets Mastercard standards for reliability, security, compliance, scalability, and performance.

• Write and maintain unit, functional, and integration tests to validate component and system behavior.

• Collaborate with AI Engineers and Data Scientists to integrate models, prompts, and evaluation approaches into larger production systems.

• Support operations through logging, monitoring, tracing, troubleshooting, incident investigation, and continuous improvement.

• Take part in code reviews and technical design discussions, document solutions, and share knowledge with peers.

All About You:

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.

• Professional experience building and supporting production-grade software systems, services, or platform capabilities.

• Proficiency in object-oriented programming and backend development using Java, Kotlin, Python, or a similar language.

• Solid foundation in software design, data structures, and the software development lifecycle.

• Experience developing APIs, services, integrations, or asynchronous workflows.

• Working knowledge of authentication, authorization, secure service-to-service communication, and API security.

• Understanding of secure coding practices, reliability, observability, automated testing, and production support.

• Ability to work in evolving problem spaces, learn emerging AI technologies, and deliver solutions iteratively, with guidance when needed.

Preferred Skills:

• Experience integrating LLMs, machine learning models, or AI services into software applications.

• Familiarity with agent frameworks, workflow engines, orchestration platforms, retrieval patterns, or AI evaluation tools.

• Exposure to audit-friendly, policy-driven platforms, guardrails, or responsible AI practices.
