Senior Java Engineer (Performance)

at  SEON Technologies

Are you a champion Senior Java Engineer? Do you love Java, Spring Boot & multithreading? Help us boost the SEON rocket ship as we assemble our super team of fraud-fighting heroes.
The product and software engineering department drives, oversees, coordinates, and executes the entire lifecycle of product development. It’s a huge job, which is why we break it down into objectives and task-oriented initiatives. That involves delegating to a bunch of teams, including Admin, Scoring, Data Enrichment, AI, Growth, Onboarding, QA, DevOps, and more—all collaborating to build the best anti-fraud tool possible.
A Senior Java Engineer in our organization brings strong software engineering expertise first but also comes with a strong mentoring mindset to support engineering teams and work closely with our engineering leadership. SEON relies on a product-led growth approach.
Our Scoring Team is the heart of SEON: we essentially collect data and provide it to customers so they can block fraud. We’re continuously adding new data sources to improve our complex real-time analysis. It’s a mission that involves core product functions such as backend and frontend development, R&D, design, and database development.
