Key Responsibilities

1. Unified AI Strategy & Technical Leadership

Design and own the end-to-end technical vision for our next-generation marketing platform, synthesizing recommender systems and LLMs into a cohesive architecture. Lead the research, design, and implementation of novel models that combine predictive signals (e.g., "what to recommend") with generative capabilities (e.g., "why it's recommended"). Establish and champion best practices across the full modeling stack, from classical ML fundamentals to MLOps for both recommender and generative models. Act as the primary technical mentor for data scientists, providing guidance on everything from feature engineering to fine-tuning LLMs.

2. Recommender System Innovation & Optimization

Architect, build, and deploy large-scale recommender systems using a variety of techniques (e.g., collaborative filtering, matrix factorization, content-based). Solve core recommendation challenges, including the cold-start problem, real-time personalization, and balancing exploration vs. exploitation. Develop and implement rigorous offline and online (A/B testing) evaluation frameworks to continuously measure and improve recommendation quality and business impact. Leverage classical machine learning models (e.g., XGBoost, Logistic Regression) to predict user behavior (e.g., propensity to click, purchase, or churn) to be used as key features in the recommendation engine.

3. Generative AI & LLM Integration

Lead the development of LLM-powered features that enhance our platform, such as campaign optimiser, creative generator, making customer data AI-ready with AI-generated metadata or creating natural language interfaces for our entire product suite. Spearhead efforts in fine-tuning and adapting pre-trained LLMs on our proprietary data to improve relevance, style, and factuality. Design and implement Retrieval-Augmented Generation (RAG) pipelines that allow LLMs to reason over our vast product or content catalogs.

4. Cross-Functional Influence & Execution

Partner with Product, Engineering, and Design leaders to translate ambitious business goals into a concrete technical roadmap. Communicate complex technical ideas and results effectively to a broad audience, from junior engineers to executive leadership. Drive projects from ideation to production, ensuring models are not only accurate but also scalable, efficient, and maintainable.

Minimum Qualifications

Bachelor's/Master's degree or PhD in a quantitative field such as Computer Science, Statistics, Mathematics, or equivalent practical experience. 7+ years of hands-on experience building and deploying machine learning models in a business environment. Expert-level proficiency in Python and its data science libraries (e.g., pandas, NumPy, scikit-learn, XGBoost, spark). Advanced proficiency in SQL for querying large and complex datasets.

2+ years of demonstrated, hands-on experience developing and deploying solutions using Large Language Models (e.g., fine-tuning, RAG, prompt engineering).

Proven track record of leading complex, end-to-end data science projects that have delivered significant business impact.

Preferred Qualifications

Experience with cloud-based ML platforms / ML ops (e.g., AWS SageMaker, MLflow) and their generative AI services

Hands-on experience with vector databases

Familiarity with frameworks like LangChain or LlamaIndex or Agent Development Kit for building LLM applications.

Knowledge of LLM operational concerns, including

cost management, latency optimization, and responsible AI principles (bias, fairness, safety)
