About The Position

Gelber Group is seeking motivated individuals for a summer internship program focused on modernizing a legacy internal web tool called “OpsWeb.” This project aims to enhance maintainability, usability, and reliability by collaborating with daily end users. Interns will gain exposure to the systems and tooling of a proprietary trading firm, work directly with Technical Operations engineers, and partner with Operations stakeholders. The internship will involve taking ownership of a modernization effort on a production web portal, including designing and implementing a shared templating approach, improving UX with shareable views, safely removing outdated features, and producing documentation. The goals are to deliver measurable improvements to a production application, learn to refactor legacy systems, build strong habits around code quality and stakeholder feedback, and determine interest in Technical Operations work within a high-performance trading environment.
