MATCH GROUP AI TEAM INTRODUCTION Match Group AI (MG AI) is the central tech organization that drives innovation across Match Group’s global portfolio, including Tinder, Hinge, Azar, Pairs, Match, BLK, etc. Our mission is to solve the most complex challenges in online dating (e.g., Recommendation, Trust & Safety, Profile Enhancement) by bridging cutting-edge AI research with excellent software engineering. Unlike brand-specific teams (e.g., Tinder, HYPERCONNECT AI), MG AI team offers the unique opportunity to impact the entire Match Group ecosystem. You won't just build for one app; we aim to develop scalable AI solutions that power Tinder, Hinge, and beyond, defining the technological gold standard for the global dating industry. * Detailed article: Introduction to Match Group AI Team (written in Korean) WORKING AS A MLSE AT MG AI While ML Engineers focus on modeling, Machine Learning Software Engineers (MLSEs) at MG AI team focus on the critical bridge between research and production. We ensure that state-of-the-art models (including LLMs and Multimodal systems) are integrated into high-traffic environments, serving millions of users in real-time. We also upload a selection of interesting problems solved by our team's engineers to the Hyperconnect Tech blog (written in Korean). * On-device AI Face Verification Pipeline Optimization * 10 Python Performance Optimization Tips for High-Performance ML Backends WHAT YOU’LL DO * Build ML Services: Design and develop backend services and distributed systems that enable the seamless consumption, scaling, and monitoring of ML models. * Build ML Pipelines: Design and develop ML serving pipelines (real-time and batch) to deliver model outputs with low latency and high reliability. * Improve Recommendation System: Improve the AI-powered personalized recommendation system to help users find better matches on Match Group’s dating apps (serve better retrieval/ranking/utility models, add better features, etc). * Co-Engineering with Brands: Engage in deep technical collaboration with engineering counterparts (Tinder, Hinge, Match, Azar, Pairs, etc.) across various global offices, including Seoul, Palo Alto, LA, Vancouver, Dallas, and Tokyo. REQUIRED QUALIFICATIONS * 2+ years of experience in software engineering, with a focus on Backend, ML Engineering, or Data Engineering. * Strong understanding of CS Fundamentals (data structures, algorithms, operating systems) and distributed system design. * Proficiency in at least one modern programming language (e.g., Python, Go, Java, Kotlin, C#) and a "polyglot mindset" to adapt to new stacks quickly. * A strong interest in how ML models are built and a passion for solving the engineering challenges of deploying them in the real world. * Proficiency in leveraging AI-powered tools (e.g., Claude Code, Codex, Cursor) to accelerate productivity. * Professional working proficiency in English. (Able to conduct business meetings and participate in complex discussions without requiring assistance.) * Fluent in Korean (Sophisticated professional interactions with native-level precision): Essential for cross-functional collaboration within the Seoul office. PREFERRED QUALIFICATIONS Experience with the full ML lifecycle, from model training to production deployment. Experience in building AI-based recommendation system. Experience in developing scalable backend servers (handling millions of users). Experience in developing and serving ML-driven services using frameworks such as vLLM, Triton, Ray Serve, or Seldon. Experience with big data or stream processing frameworks (e.g., Spark, Flink, Kafka) for building robust ML data pipelines. Experience in collaborating with cross-functional teams and diverse organizations. Fluent in English (Sophisticated professional interactions with native-level precision and an understanding of cultural nuances.) #mg #LI-YN1
