Senior Backend Java Developer

Job Title: Senior Backend Java Developer (IB / Partner Platform)
Company: VCG Tech Limited
Location: Remote
Employment Type: Full-Time

Role Purpose

This role owns the backend services behind our introducing-broker and partner program: partner onboarding, multi-level partner commission and rebate logic, and the reporting that partners rely on to understand their earnings. These services sit at the intersection of trading activity and partner payouts, so getting them right matters commercially and to the trust partners place in the program. You will design, build and operate Java microservices that must be accurate, reliable and maintainable on a live financial platform.

Day to day you will write and review clean, well-tested code, design sound APIs, and integrate with the trading platform and other backend services through REST and event-driven messaging. You will work in a focused, remote product team, collaborating closely with fellow engineers, product and QA, and sharing responsibility for the reliability of what you ship. As a senior individual contributor you will set a high bar in code review, mentor through example, and report into the team's engineering lead.
