Job Summary

Own the end-to-end optimization and AI-assisted creative workflow for cross-channel advertising, from budget pacing and bid rules to scalable generation and production deployment.

Growth/Optimization: Build and solve cross-channel budgeting, bidding rules, and production-ready AI pipelines with data engineers.
Creative & Asset Engine: Fine-tune LLMs and multi-modal models to generate ad copy and visuals at scale for landing pages and ads.
Experimentation & Measurement: Design A/B tests, analyze financial impact, and organize large keyword lists into coherent ad groups.

Job Description

Responsibilities

Formulate and solve optimization problems for cross-channel budget pacing and intelligent bid adjustments across major search platforms.
Perform complex exploratory data analysis (EDA) to evaluate the financial impact of strategic initiatives and the performance of various creative combinations.
Utilize and fine-tune Large Language Models (LLMs) to generate and iterate high-converting ad copy and brainstorm keywords at scale.
Integrate multi-modal/image generation models to produce and optimize visual assets for ads and landing pages.
