Full job description

Principal AI/ML Engineer role in AdTech team to design, build, and deploy scalable machine learning models and AI-driven features for advertising platform. Responsibilities include leading ML solution design, architecting end-to-end ML pipelines for real-time bidding and targeting, defining AI/ML technical strategy, developing AI agentic workflows for campaign automation, collaborating cross-functionally, ensuring system performance and reliability, and mentoring engineers. Requires 10+ years experience in software engineering or data science with 3-5 years in principal or lead ML role, expertise in programmatic advertising ecosystem, proficiency in Java, Go, Python, experience with ML frameworks (PyTorch, TensorFlow), big data tools (Spark, Kafka, Hadoop), cloud platforms (AWS), SQL/NoSQL databases, containerization (Docker, Kubernetes), and strong communication skills. Salary range $300,000 - $400,000. Location: San Francisco, California, United States.

What you'll do

  • Lead the design and implementation of scalable, high-performance, and resilient ML solutions for AdTech use cases.
  • Set technical direction for integrating AI/ML into the Demand-Side Platform and broader ad tech stack.
  • Architect and evolve the end-to-end machine learning pipeline – from data ingestion and training to real-time inference for real-time bidding, targeting, and optimization algorithms.
  • Ensure models seamlessly integrate with ad serving architecture and handle low-latency, high-throughput requirements.
  • Define the technical roadmap and vision for AI/ML in the platform, evaluating new tools and techniques including deep learning and LLMs.
  • Develop intelligent systems using AI agents and agentic workflows to automate and optimize end-to-end campaign processes.
  • 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.
  • Ensure system robustness and stability for ML services in a high-concurrency, low-latency environment.
  • Optimize algorithms and infrastructure for speed and scalability, and implement monitoring to maintain model performance and uptime in production.
  • Provide technical guidance and mentorship to other engineers and data scientists, fostering 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.
