Sr. Java Developer at Robert Half

Position Intel: This is a new role that opened up due to growth. Looking for a strong backend engineer with deep experience building large-scale, high-volume, low-latency applications who truly understands the architectural challenges behind systems that operate at an “Amazon Prime Day” level of traffic. This person should know what to plan for, who to collaborate with, and how to step in during critical, fire-drill situations. The team is mostly remote, with a preference for candidates in Southern California or Chicago, since they meet in person quarterly for design and planning sessions. The role is about 50% coding on a high-volume backend application that powers fraud-detection JavaScript embedded across major merchant websites—collecting device data, identifying bots, detecting fraud, and supporting account protection. The frontend is minimal; expertise in Java, Spring Boot, Postgres, Oracle, and familiarity with non-relational databases (DynamoDB is fine) is essential. The team has 17 developers total, with this role joining the backend server group. Fintech or trading experience is a strong plus.Top Requirements:5+ years of experience with JavaDeveloping large scale applicationsFin tech or trading is a plus
