Senior Software Engineer - Player Platform, Revenue Protection

Riot engineers bring deep knowledge of specific technical areas but also value the opportunity to work across a wide range of domains. As a Senior Software Engineer, you'll dive into cross-functional projects that contribute to team cohesion and advance broader product goals. You'll lead by example, providing other engineers with a strong model of technical excellence, thoughtful collaboration, and continuous improvement.

Revenue Protection ingests payment data from multiple global partners, reconciles every transaction end-to-end, and emits real-time fraud signals that safeguard player trust and Riot’s bottom line. We lean on CloverDX for ETL and Java/Kotlin microservices for business logic, and we’re expanding into Kafka streaming and machine-learning-driven trust-list and velocity-check models. Your architecture and coding skills will be central to making those capabilities real and multiplying our fraud-prevention impact.  You will report to the team Software Engineering Manager.

Responsibilities:

• Design & evolve CloverDX pipelines that ingest, transform and validate high-volume payment data.
• Build Java/Kotlin microservices (Spring Boot, REST/async messaging) that power real-time reconciliation and fraud decisions.
• Help bring ML-driven fraud-detection models to production
• Automate deployment & observability—CI/CD for Clover graphs, Docker/K8s releases, Datadog alerts, runbooks and SLOs.
• Champion operational excellence: on-call rotation, incident triage, cert rotation, IAM/ACL hygiene for PCI-scope systems.
• Mentor teammates & unblock analysts in SQL, Python and CloverDX best practices

Required Qualifications: 

• 5+ years of professional software-engineering experience 
• Proficiency in Java or Kotlin and designing distributed, fault-tolerant services.
• Hands-on expertise with ETL/ELT platforms—CloverDX strongly preferred.
• Strong SQL and data-modelling skills for financial reporting.
• Demonstrated ownership of live services: SLOs, on-call, RCAs.

Desired Qualifications:

• Experience working on data- or finance-critical systems.
• Experience building or integrating machine-learning models for classification, risk scoring or anomaly detection.
• Bachelor’s degree in Computer Science or related field.
• Working knowledge of payment-processing flows (auth, capture, chargeback) and fraud-risk concepts (velocity checks, trusted-buyer lists).
• Expertise with Kafka or other streaming platforms.
• Familiarity with observability stacks (Datadog, Prometheus).
• Python scripting for data-quality checks, CI test harnesses and ops automation (e.g., self-healing ETL).

For this role, you'll find success through craft expertise, a collaborative spirit, and decision-making that prioritizes your fellow Rioters, who are the customers of your work. Being a dedicated fan of games is not necessary for this position!
