Overview
Data Foundations, part of Business & Market Insights, solves shared data problems for Mastercard's analytics products: secure customer data exchange, consistent business definitions and metrics, reference datasets, data quality and AI-assisted customer data onboarding. Engineering and product set direction together, and we own outcomes, not just delivery. Where enterprise platforms fit, we reuse and shape them. Where there is a shared gap, we solve it once.
We are looking for a Software Engineer II to join our growing Pune-based team. You will start with reliable ingestion of customer and third-party data, independently delivering defined components and working with senior engineers on bigger design decisions. This role focuses on platform software and automation; if you mainly build data transformations and datasets, see our Data Engineer II role. In your first few months you will deliver scoped features and fixes, join production support and automate a manual operational step.
Role
- Build, test and operate services, APIs, connectors and automation for customer data exchange, workspace setup and pipeline orchestration.
- Deliver defined components independently, from technical approach through release, monitoring and support.
- Write automated tests and useful documentation.
- Replace manual operational steps with code.
- Investigate production issues, fix defects and support root cause analysis.
- Break down and estimate work, give input on design, feasibility and risk, and give and receive code review feedback.
All About You
- Intermediate skills in Python or another language such as Java, Scala or C#/.NET, plus working SQL.
- Knowledge of source control, automated testing, secure coding, code review and CI/CD.
- Experience building software on a public cloud; we use AWS and Databricks.
- Interest in data platforms and how data moves between systems.
- Product curiosity: you ask who needs the work and why.
- Clear communication and practical use of AI tools, with sound judgement on when to trust their output.
Desirable:
- Experience with Spark or Snowflake.
- Experience with REST APIs, cloud storage integrations, or C#/.NET and React-based tooling.
- Experience exchanging data with external partners through cloud storage, SFTP or APIs.
- Experience with infrastructure as code or deployment automation.
