Profile match
Mastercard is an American payments technology company whose origins date to 1966, when a group of banks formed the Interbank Card Association to compete with BankAmericard. Like its main rival it does not issue cards or extend credit; it operates the network that authorises, clears and settles transactions between issuing banks, acquirers and merchants in more than two hundred countries. Headquartered in Purchase, New York, the company has built a large services business alongside the core network, covering fraud and identity products through its Ethoca and RiskRecon acquisitions, open banking, consulting and loyalty programmes.

  • Backend Engineering: Strong proficiency in Node.js and TypeScript/JavaScript, including API design, asynchronous processing, event-driven systems, and backend architecture.
  • System Design: Demonstrated expertise in distributed systems, scalability, reliability, database design, caching, messaging, and system integration.
  • AI/ML Engineering: Strong understanding of machine learning, deep learning, neural networks, transformer architectures, and LLM internals.
  • LLM Training: Practical experience training LLMs from scratch and taking trained models through evaluation, optimization, and production deployment.
  • ML Frameworks: Hands-on proficiency in Python and frameworks such as PyTorch or TensorFlow.
  • Data Engineering: Experience with data pipelines, dataset preparation, data quality, vector embeddings, and efficient data processing.
  • LLM Systems: Working knowledge of tokenization, attention mechanisms, inference optimization, GPU utilization, model evaluation, and serving infrastructure.
  • Infrastructure and Deployment: Experience with Docker, CI/CD, cloud or on-premises infrastructure, monitoring, logging, and production operations.
  • Databases: Strong understanding of SQL and NoSQL databases, data modeling, query optimization, and performance tuning.
  • Engineering Practices: Proficiency in automated testing, debugging, code reviews, version control, security, and maintainable software design.
