• Leverage LLMs and generative AI to enable autonomous campaign management tasks such as audience segmentation, dynamic bid adjustments, and creative asset generation
• Partner with engineering, product, and data science teams to translate marketing objectives into ML-driven solutions
• Work closely with stakeholders to deliver innovative features powered by Large Language Models (LLMs)
• Ensure system robustness and stability for ML services in a high-concurrency, low-latency environment
• Optimize algorithms and infrastructure for speed and scalability
• Implement monitoring to maintain model performance and uptime in production
• Provide technical guidance and mentorship to other engineers and data scientists
• Foster a culture of excellence in engineering and ML best practices
• Review code and models, share knowledge, and champion continuous improvement across teams

Requirements

• 10+ years of experience in software engineering or data science, with at least 3-5 years in a principal engineer or lead ML role (preferably in the AdTech/MarTech industry)
• Proven experience designing and building high-throughput, low-latency distributed systems or data pipelines for large-scale applications
• Deep expertise in the programmatic advertising ecosystem, including Demand-Side Platforms (DSPs), real-time bidding (RTB), Supply-Side Platforms (SSPs), and ad exchanges
• Proficiency in programming languages such as Java, Go, and Python for building both data-intensive backend services and ML tools
• Hands-on experience with machine learning frameworks and libraries, especially PyTorch or TensorFlow, for developing and training models
• Strong experience with big data and streaming frameworks (e.g., Apache Spark, Kafka, Hadoop) for processing and analyzing large datasets
• Expertise with cloud platforms (preferably AWS) and related services for scalable ML model deployment and data storage
• Experience with various data stores, including both SQL and NoSQL databases (e.g., MySQL/PostgreSQL, Cassandra, DynamoDB, Redis)
• Familiarity with containerization and orchestration technologies (Docker, Kubernetes) for deploying and managing services at scale
• Excellent communication, presentation, and interpersonal skills, with ability to convey complex ML concepts to technical and non-technical stakeholders
