Role Overview
We are seeking a highly skilled Specialist with 5 to 7 years of hands-on experience in Core Java, React, and cloud-native architecture to join our client's Investment Banking engineering team. In this role, you will design, build, and maintain high-throughput, low-latency applications tailored for risk management systems.
You will lead technical initiatives across a modern tech stack—combining event streaming (Kafka/Flink), microservices, AWS cloud infrastructure, and modern frontend frameworks—to deliver secure, resilient, and real-time financial solutions for our client.
Key Responsibilities
- End-to-End System Design & Development: Architectural design and development of robust microservices and interactive user interfaces using Core Java, Kotlin, Spring Boot, and ReactJS.
- Real-Time Data Processing: Build and maintain scalable event-driven architectures utilizing Apache Kafka and Apache Flink for real-time risk data streaming.
- API & Integration Engineering: Design, implement, and maintain high-performance RESTful APIs and gRPC services for seamless cross-system and frontend-backend communication.
- Cloud & DevOps Integration: Deploy, scale, and manage cloud-native applications on AWS (leveraging AWS Lambda, ECS/EKS) and Kubernetes; collaborate with client DevOps teams to maintain CI/CD pipelines.
- Frontend Excellence: Construct responsive, accessible, and performant UI components using TypeScript, HTML5, CSS3, and Redux/Context API.
- Technical Leadership & Mentorship: Provide technical guidance, code reviews, and architectural mentorship to junior and mid-level developers.
- Domain Alignment: Partner with quantitative analysts, risk officers, and product owners to translate complex risk management requirements into technical implementations.
- System Optimization & Reliability: Conduct performance tuning, memory profiling, and multithreading optimizations; troubleshoot and resolve production incidents to uphold high availability.
- Quality & Compliance: Maintain high code quality through rigorous automated testing, static analysis, secure coding standards, and compliance with banking regulations.
