Role Description
As a Principal AI/ML Engineer in our AdTech team, you will be a key individual contributor driving the development of advanced machine learning models and AI-driven features for our advertising platform. You will design, build, and deploy ML solutions for campaign optimization, user personalization, and creative content generation, operating at large scale and low latency to handle billions of ad events per day. This role requires deep expertise in machine learning techniques and the programmatic advertising ecosystem (e.g., real-time bidding and digital marketing data). You will work closely with engineering, product, and data science teams to ensure our ML systems are highly performant, scalable, and reliable. You will also spearhead innovation by leveraging large language models (LLMs) and intelligent agent architectures to create new capabilities that automate and enhance advertising campaigns.
Key Responsibilities
- Machine Learning Leadership: Lead the design and implementation of scalable, high-performance, and resilient ML solutions for AdTech use cases. You will set technical direction for integrating AI/ML into our Demand-Side Platform and broader ad tech stack.
- ML System Design: Architect and evolve the end-to-end machine learning pipeline – from data ingestion and training to real-time inference, for our real-time bidding, targeting, and optimization algorithms. Ensure that models seamlessly integrate with our ad serving architecture and handle low-latency, high-throughput requirements.
- Technical Strategy: Define the technical roadmap and vision for AI/ML in our platform, evaluating new tools and techniques (including the latest in deep learning and LLMs) and making strategic build-vs-buy decisions. Continuously assess emerging technologies to keep our AdTech capabilities on the cutting edge.
- AI & Agentic Applications: 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.
- Cross-Functional Collaboration: Partner with engineering, product, and data science teams to translate marketing objectives into ML-driven solutions. Work closely with stakeholders to deliver innovative features – including those powered by Large Language Models (LLMs), that enhance our advertising products.
- Performance & Reliability: 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.
- Mentorship & Best Practices: 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.
Required Qualifications
- 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.
Preferred Qualifications
- Experience with Large Language Models (LLMs) and generative AI applied to advertising, for example, using AI to generate ad copy, optimize creative content, or personalize messaging.
- Experience designing and implementing agentic workflows that enable autonomous decision-making and real-time optimization in marketing campaigns.
- Experience with machine learning model serving and optimization for real-time inference applications (latency-critical environments).
- Familiarity with modern data lake and table formats (e.g., Apache Iceberg, Apache Hudi) for managing large-scale analytical datasets.
- Knowledge of microservices architecture and event-driven design patterns in distributed systems.
- A track record of contributions to open-source projects or speaking at industry conferences, demonstrating thought leadership in AI/ML.
BENEFITS & PERKS
- Unlimited PTO
- Excellent medical, dental, and vision coverage
- Employee Equity

Search ML Engineer Jobs in CaliforniaML Engineer Jobs in California: Frequently Asked Questions
Which companies in California sponsor visas for ML engineers?
Large technology companies with established immigration programs, including Google, Apple, Meta, Amazon Web Services, and Microsoft's Bay Area offices, consistently file H-1B petitions for ML engineers. Beyond the major players, California-based AI startups and research labs such as OpenAI, Anthropic, and Scale AI have also sponsored work visas for machine learning roles in recent years.
Which visa types are most common for ML engineer roles in California?
The H-1B is the most common visa for ML engineers in California because machine learning roles at the bachelor's level and above qualify as specialty occupations. Candidates already in the U.S. on F-1 OPT, including the 24-month STEM extension, frequently use that period to secure H-1B sponsorship. O-1A visas appear less often but are an option for engineers with a documented record of significant contributions or recognition in the field.
Which cities in California have the most ML engineer visa sponsorship jobs?
The San Francisco Bay Area, including San Francisco, Sunnyvale, Mountain View, and Menlo Park, accounts for the largest share of ML engineer sponsorship activity in the state. Los Angeles has grown steadily as a secondary hub, driven by companies in media technology, autonomous vehicles, and defense AI. San Diego has a smaller but active cluster tied to biotech AI and defense contractors.
How to find ml engineer visa sponsorship jobs in California?
Migrate Mate is built specifically for international candidates seeking visa sponsorship jobs, including ML engineer roles in California. You can filter by state and role to surface companies with active sponsorship history rather than sifting through listings that may not lead to a petition. Reviewing the Department of Labor's H-1B disclosure data alongside Migrate Mate listings helps confirm which California employers have filed for similar positions recently.
Are there any California-specific considerations for ML engineers seeking visa sponsorship?
California's prevailing wage requirements under H-1B rules often reflect some of the highest wage levels in the country given the state's cost of living, meaning employers must offer competitive compensation that meets Department of Labor standards for the relevant metropolitan area. The state's large research university pipeline, particularly UC Berkeley, Stanford, and UCLA, also creates significant competition for sponsorship slots, so candidates with specialized expertise in areas like large language models or computer vision tend to stand out.
What is the prevailing wage for sponsored ml engineer jobs in California?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
