AI Data Engineer

The role

This person will design and develop Agent-based Self-Improvement AI Pipelines connecting model evaluation, data generation, and training experiments. They will also analyze Foundation Model performance and improve the AI Data Platform.

What you will do

• Design and develop Agent-based Self-Improvement AI Pipeline connecting model evaluation, data generation, and training experiments
• Analyze Foundation Model performance and failure cases by benchmark to derive improvement tasks
• Generate and refine synthetic and reference data for training and evaluation and automate Data Quality Control
• Compare and verify performance changes based on data composition and training methods in SFT, RLHF, RLVR, Mid-training, and Post-training processes
• Operate AI Data Platform and advance features such as On-Prem Data Storage, Data Versioning, and Experiment Tracking

Required qualifications

• Understanding of Machine Learning and Deep Learning and experience in AI model and data research and development
• Understanding of LLM-based Agent System structure and Agent Orchestration
• Ability to define model and data problems and connect performance improvement through Experimental Design and Statistical Analysis
• Experience collaborating with researchers and engineers to specify technical tasks and apply them to actual research or service environments through implementation and verification
• Ability to actively use Code Agents and verify output quality to increase development productivity

Nice to have

• Experience publishing first-author papers in top-tier NLP, ML, AI conferences such as ACL, EMNLP, NeurIPS, ICML, ICLR, AAAI
• Experience improving actual model performance through large-scale Training Dataset construction and Data Curation
• Experience directly developing Benchmarks, Automated Evaluators, or Reward Models/Verifiers
• Experience deploying and operating AI services or Data Platforms in production environments to improve safety, processing speed, and cost

Before you apply

• LG AI Research is not a military service designated company, so recruitment and transfer of technical research personnel is not possible
• Document screening, 1st technical interview (online), LG Way Fit Test & coding test, 2nd technical interview (online), 3rd technical interview (online), and final interview (on-site)
