Project Description: 

Our team is responsible for developing cutting-edge backtesting and simulation software that powers large-scale quantitative research operations and portfolio production. 

This platform is utilized by thousands of researchers, portfolio managers, and technologists to process vast and diverse datasets, generating profitable trading signals. Currently, the platform supports millions of binaries daily, operating at an unmatched scale with stringent performance and throughput requirements. 

As the team embarks on a multi-year initiative to build a more powerful, scalable, and efficient platform to drive the firm’s next growth decade, we seek a talented individual to join us. In this role, you will primarily assist users in resolving technical challenges they are facing daily while also having a chance to contribute innovative solutions to the core platform. 

  • You will be using/developing/maintaining advanced applications of C++, Python, Linux system programming, and concurrency. 
  • You will be interacting with world-class technologists as well as quants daily to figure out a solution to their problem.

Client description:

This is a global investment firm that leverages data, mathematics, and advanced technology to make informed decisions in financial markets. The company develops computer-based strategies to identify profitable opportunities and manage assets across various countries and investment classes. The core focus is on innovation and research to maintain a competitive edge in the financial world. The firm does not manage money for individual clients or offer retail banking services. Instead, it works with large institutional investors such as pension funds, university endowments, sovereign wealth funds, Foundations, other asset managers, or hedge funds. This institution entrusted the firm to grow its investments through sophisticated, data-driven strategies. The firm does not provide personal financial advice; instead, it builds complex financial models and analyzes vast amounts of data to uncover market opportunities and invest on behalf of its clients. In essence, institutional clients allocate capital, and the firm uses algorithms, deep research, and cutting-edge technology to pursue strong investment returns.
