Senior AI/ML Engineer

We are seeking a highly skilled Senior AI/ML Engineer to lead the design and deployment of scalable AI/ML solutions focused on real-time personalization, recommendation systems, and customer knowledge graphs.

The ideal candidate will have strong hands-on experience with Python, Pandas, PySpark, recommender systems, graph modeling, and graph databases, along with experience building production-grade ML systems that drive measurable improvements in customer engagement, conversion, and personalization.

You will work across ML engineering, data engineering, MLOps, and product/business teams to build scalable batch and real-time ML solutions and deliver context-aware recommendations at scale.

Key Responsibilities

• Design and build collaborative, content-based, and hybrid recommendation systems.
• Develop real-time personalization pipelines and ranking models.
• Architect and implement end-to-end ML systems supporting both batch processing and low-latency streaming inference.
• Build and maintain customer knowledge graphs using technologies such as Neo4j and Amazon Neptune.
• Model relationships between customers, users, products, interactions, and behavioral data.
• Enable Customer 360 insights and context-aware recommendations.
• Develop scalable data and ML pipelines using Python, Spark, and Kafka.
• Perform feature engineering, model training, evaluation, and deployment.
• Implement and optimize recommendation algorithms including matrix factorization, deep learning, and ranking models.
• Drive experimentation through A/B testing and optimize models for CTR, engagement, conversion, and other business KPIs.
• Implement entity resolution and record linkage capabilities.
• Apply MLOps practices, including CI/CD, model monitoring, model lifecycle management, and production reliability.
• Monitor data quality, model performance, scalability, and system reliability.
• Work with large-scale data environments and design solutions capable of handling high-volume workloads.
• Collaborate with Product, Data Engineering, Business, and other technical stakeholders to translate business requirements into scalable AI/ML solutions.
• Mentor junior and mid-level engineers and contribute to technical design and architecture decisions.

Required Qualifications

• Strong hands-on experience in AI/ML Engineering and production machine learning systems.
• Strong Python programming skills.
• Hands-on experience with Pandas and PySpark.
• Proven expertise in Recommendation Systems / Recommender Systems.
• Experience with collaborative filtering, content-based recommendations, hybrid models, matrix factorization, deep learning, and ranking models.
• Strong experience with Graph Modeling.
• Hands-on experience with graph databases such as Neo4j or Amazon Neptune.
• Experience with RDF, graph embeddings, or related graph technologies.
• Experience with Entity Resolution / Record Linkage.
• Strong understanding of ML lifecycle, experimentation, model evaluation, and deployment.
• Experience with recommendation evaluation metrics such as NDCG, MAP, Precision, and Recall.
• Experience developing scalable pipelines using Python, Spark, and Kafka.
• Experience with feature engineering, model training, and production deployment.
• Strong understanding of MLOps, CI/CD, monitoring, and model lifecycle management.
• Ability to build and support production-grade AI/ML solutions, not just research prototypes.
• Strong problem-solving and analytical skills.
• Excellent communication and collaboration skills.

Preferred Qualifications

• Experience building real-time ML and personalization systems.
• Experience working with large-scale TB/PB data environments.
• Experience with low-latency model serving and real-time inference.
• Experience with Customer 360, customer intelligence, or behavioral analytics.
• Experience with streaming technologies such as Kafka.
• Experience with graph embeddings and knowledge graph solutions.
• Experience optimizing recommendation systems for CTR, engagement, conversion, and personalization.
• Strong experience working with cross-functional Product, Data, Engineering, and Business teams.
• Experience mentoring engineers and leading technical initiatives.
