Role Overview:
Coupang’s Risk, Fraud & Trust Engineering organization is building next-generation platforms that protect the marketplace ecosystem through intelligent, scalable, and real-time decisioning systems. The team develops highly scalable fraud detection and risk evaluation platforms that process massive volumes of transactions, seller activities, and marketplace events while ensuring excellent customer and seller experiences.
As a Senior Staff Engineer, you will lead the architecture and development of large-scale ML-powered data platforms that bridge the gap between Data Science and Engineering. You will be responsible for building the infrastructure, real-time data pipelines, and serving systems required to deploy, scale, and operate machine learning models in production.
This role requires deep expertise in distributed systems, stream processing, data infrastructure, and ML model operationalization. You will partner closely with Data Scientists, Software Engineers, Product Managers, and business stakeholders to ensure fraud detection and risk models are efficiently deployed, highly performant, reliable, and capable of meeting strict business SLAs.
You will establish technical vision, drive architectural direction, and raise engineering standards across the organization while enabling the next generation of fraud prevention and trust platforms at Coupang scale.
Key Responsibilities:
- Lead the architecture, design, and development of scalable data and ML infrastructure supporting fraud detection, risk evaluation, and trust systems.
- Build and optimize large-scale batch and real-time data pipelines capable of processing high-volume events with low latency and high reliability.
- Own the end-to-end productionization of machine learning models, ensuring deployment architectures meet performance, scalability, and operational requirements.
- Partner closely with Data Scientists and Engineering teams to bridge model development and production deployment, translating complex modeling requirements into scalable engineering solutions.
- Define long-term technical vision and roadmap for data processing, ML platform capabilities, and fraud detection infrastructure.
- Lead complex cross-functional initiatives, establish engineering best practices, and raise the bar for system scalability, reliability, and operational excellence.
- Mentor senior engineers, drive technical decision-making, and provide leadership during critical production incidents and architectural reviews.
Basic Qualifications
- 13+ years of experience in backend engineering, data engineering, or large-scale distributed systems development
- Strong experience building large-scale, real-time distributed data processing systems
- Hands-on experience with data streaming technologies such as Apache Flink, Kafka, Spark Streaming, or similar frameworks
- Strong proficiency in Java-based backend development and distributed system architecture
- Experience designing and building low-latency, high-throughput data pipelines and serving systems
- Experience deploying, scaling, and optimizing machine learning models in production environments
- Strong knowledge of system design, scalability, fault tolerance, and operational excellence
Preferred Qualifications
- Experience in fraud detection, risk systems, trust & safety, payments risk, or similar domains
- Familiarity with commerce, marketplace, fintech, or payments ecosystems
- Experience building ML platforms, model-serving infrastructure, feature stores, or inference pipelines
- Experience operating systems that process millions of events or transactions per day
- Experience partnering closely with Data Science teams to productionize machine learning models
- Familiarity with leveraging GenAI tools for software development, debugging, testing, and engineering productivity
- Experience working with cloud-native architectures, containerized environments, and modern infrastructure platforms
