About Faezeh Hajiaghajani Memar

I’m a machine learning engineer focused on generative AI, retrieval, and ranking for search and recommendations. Most recently, at LinkedIn, I have built LLM-powered retrieval systems end-to-end—from data and modeling to evaluation and production. I’ve contributed to agentic search experiences for both job seekers and hirers, including LLM-based entity understanding. I’m passionate about meaningful impact and end-to-end ownership, drawing on ~10 years of experience in computer science and machine learning.

Experience

1. Machine Learning Engineer

   Linkedin

   Nov 2021 — Present · San Francisco, CA, US

   Led design & implementation of EBR for search and recommendations: LLM-based embedding generation, two-tower training, LLM teacher training for evaluation; productionized end-to-end- Owned the Job Search Entity Recognition Unit in Job Search\'s Agentic Project: turned free-form conversations into structured search/reco queries; contributed to different parts of the end to end stack (LLM entity extraction, search integration, LLM result presentation), built the evaluation framework & prompts, and mitigated hallucinations; partnered cross-functionally with Product/Eng- Shipped real-time member-activity features into job search/recs → +1.65% Qualified Applications and +1.0% CTR in job search/rec models- Contributed to enhancing ranking l2 and retrieval layers for Job Search: e.g, impression discounting, score calibration (improved OE), and richer member/job features—lifting downstream models.
