Job Description

We are looking to hire a software engineer to be part of the Security Engineering team at Visa where you will be building and engineering security products utilizing some awesome technology like Rust, Go, Functional Programming, and much more! You will be joining a team of experienced security engineers, as well as world class researchers and experts in the areas of software engineering, artificial intelligence, cryptography, and other related fields to build technologies necessary to secure Visa's core infrastructure and assets. 

Essential Functions: 

  • Software Engineer first: Build, design, engineer, and develop software and services that deliver security functionality and improve security efficiency and capabilities through automation. The candidate needs to possess software engineering skills that allow them to build new capabilities and solutions vs. simply integrating an existing open source platform or operating a vendor solution.
  • Security philosophy: Refactor and optimize existing code using more robust type-safe and memory safe languages while incorporating faster data piping and parallel processing frameworks. Create requirement and design documents that account for security risks in new or existing systems with architectures to mitigate them within risk appetite.
  • Performance: Engineering of products and services while accounting for computability and complexity (e.g. NP-complete problems) and security architecture (e.g. memory, cache, deadlocks, etc.)
  • ​​R&D: Develop prototypes and algorithms (e.g. searching, sorting, optimization, dynamic programming) while performing data engineering tasks around aggregation and data synthetization from a multitude of structured and unstructured data sources. Research and develop security assessments of existing solutions as well as defining security architectures for new solutions. 
  • Presentation skills: Present results to a cross section of employees, including senior leaders at Visa. Utilize graduate-level research and analysis skills. Assist in shaping overall direction, life-cycle management, and leadership for Information Security architecture and technology related to Visa.
