The posting

Match Group AI Team Introduction

  • Detailed article: Introduction to Match Group AI Team (written in Korean)

Working as a Senior MLSE at MG AI

  • On-device AI Face Verification Pipeline Optimization
  • 10 Python Performance Optimization Tips for High-Performance ML Backends

What You’ll Do

  • Lead Projects Across Teams: Turn a broad goal into a concrete plan, and keep ML Engineers, PMs, and brand partners across our global offices (Palo Alto, LA, New York, Vancouver, Dallas, Tokyo) aligned. Clear blockers, including ones outside our team.
  • Design and Build ML Systems: Design backend services and real-time/batch data pipelines that bring ML models to production, from first prototype to millions of users. Work as a real technical partner to ML Engineers.
  • Serve Models Fast and at Low Cost: Serve deep learning models and large language models with low latency and reasonable GPU cost. Improve throughput with batching, caching, and better use of hardware.
  • Raise the Bar: Set the example in problem definition, design docs, and AI-driven development, and help other engineers grow.

Required Qualifications

  • Project Ownership (most important): A track record of leading a complex project from a rough goal to a production system you could stand behind: defining the problem, choosing the technical direction, and owning the outcome. You can explain the trade-offs behind your technical and product decisions.
  • Engineering Experience: 5+ years of software engineering (backend, ML systems, data engineering, or similar), including building and running services or data pipelines in production.
  • System Design: You can design scalable, reliable systems and clearly explain the trade-offs.
  • Hands-on Coding With AI: You write clean, well-tested code (Python preferred), and AI coding agents are part of your daily work.
  • High Agency and Grit: You find what needs to be done and drive it to a result fast, without waiting for instructions or cutting corners on quality. When you hit a wall, you find another way.
  • Collaborative and Coachable: You understand what others really need and can persuade them. You take feedback well, act on it, and use AI to learn new things quickly.
  • Professional Working Proficiency in English and Korean: Able to lead business meetings and take part in complex discussions without help.

Preferred Qualifications

  • Have a strong base in CS fundamentals, or have worked closely with ML Engineers on how models are trained and served
  • Have worked as a tech lead or manager
  • Have built Trust & Safety systems, recommendation system, AI product features, or ML APIs used by multiple teams
  • Have served ML models (vLLM, Triton, Ray Serve) or built large-scale backends and data pipelines (Spark, Flink, Kafka)
  • Have turned vague product ideas into something users love, without every detail spelled out
  • Have worked with teams in other companies, countries, or time zones
  • Native-level English

Hiring Process

  • Work type: Full-time
  • Legal Entity: Hyperconnect / Brand: Match Group AI
  • Recruitment Process: Resume Review > Technical Interview > Technical Deep-dive & Cultural Alignment Interview > Offer
  • (* Please note that part of the interview process may be conducted in English)
  • For the document screening stage, only successful candidates will be individually notified of the results.
  • Application documents: A detailed, career-based English resume (PDF) in free format

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
