Software Engineer Internship (Technical Operations Team) - Summer 2026
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 role involves improving the tool's maintainability, usability, and reliability by collaborating with daily end users to ensure changes are practical and non-disruptive. Interns will gain hands-on experience in a proprietary trading firm's systems and tooling, work directly with Technical Operations engineers, and take ownership of a modernization effort on a production web portal. The project includes designing and implementing a shared templating approach, improving UX with shareable views, safely removing outdated features, and producing documentation. The internship aims to deliver measurable improvements to a production application, teach refactoring of legacy systems, build strong habits around code quality and stakeholder feedback, and help interns determine their interest in Technical Operations within a high-performance trading environment.
