Java Developer - Financial Credit Risk Control
Location – Abu Dhabi
About The Role
Focus on financial credit scenarios (personal consumer credit, corporate credit, supply chain finance). Design, develop, and iterate Java-based credit risk systems (full lifecycle: pre-loan → in-loan → post-loan). Mitigate credit/fraud/compliance risks, protect financial assets, and ensure compliance with CBIRC/PBOC regulations.
Key Responsibilities
Build Java-based credit risk systems (approval, anti-fraud, post-loan monitoring) to support credit applications, line reviews, and overdue collection.
Design high-availability APIs (pre-loan ≤300ms response, post-loan ≤500ms) for peak concurrency (thousands of requests/sec).
Use Java ecosystems (Spring Boot/Cloud Alibaba, Nacos, Apollo, Seata) to ensure microservice stability and data consistency (e.g., prevent duplicate loans).
Translate risk rules (CBIRC compliance, blacklists) and scoring models (A/B/C cards) into Java code.
Develop a dynamic rule platform (online editing, grayscale release) and optimize efficiency (Redis caching, async computing).Integrate ML models (TensorFlow/PyTorch) as RESTful APIs for real-time scoring.
Connect to financial data sources (central bank credit, third-party providers like BaiRong) via MyBatis/Spring Data JPA; build risk data marts.
Develop real-time dashboards (track NPL, M1/M3, fraud rate) and regulatory alerts (15-minute response).
Process batch data with Flink/Spark (monthly credit sync, repayment calculations).
Compliance & Security
Implement data security (desensitization, RBAC, audit logs) to meet Personal Information Protection Law.
Support regulatory audits (AML, Internet Loan Measures) and fix system vulnerabilities (SQL injection, API bypass).
Requirements
Bachelor’s in CS/Software/FinTech; 3+ years backend dev, 1.5+ years in financial credit risk (banks/consumer finance/fintech).
Proficiency in Java (JDK 11+): JVM tuning, concurrency (ThreadPool); familiar with Spring Boot/Cloud, Seata, MySQL (sharding), Redis (cluster).
Core Skills
Experience in Java credit risk systems (full lifecycle) and rule engines (Drools/Easy Rules) preferred.
Familiar with Flink/Spark for real-time/batch data; ability to design high-availability microservices (circuit breaking, distributed locks).
Knowledge of financial security (API signature, SM4/SM2) and regulatory requirements (Cybersecurity Law).
Preferred
Experience in bank/fintech core credit systems
ML model engineering (TensorFlow → Java APIs) or certifications (FRM, CISP, CFA).
