[Hiring] AI Engineering Lead @Stagwell Global

Role Description

We are seeking a strategic and technical AI Engineering Lead to spearhead the development, deployment, and optimization of our Machine Learning models and Generative AI workflows. This is a high-priority leadership role designed for an expert who doesn't just write code but understands the full lifecycle of a data science program—from experimentation to production-grade maintenance.

• Lead the end-to-end lifecycle of ML and Generative AI models, including data structuring, information gathering, prototyping and experimentation, implementation, deployment, and continuous monitoring.
• Act in a lead capacity by delegating tasks effectively and overseeing the "experiment-deploy-measure" cycle.
• Deploy and maintain sophisticated AI applications (e.g., chat applications, document analysis models) and iterate based on user behavior and feedback.
• Prepare decks and reports for the CEO and marketing teams to translate complex technical milestones into clear business updates.
• Maintain and scale a Python-based backend, ensuring seamless integration with our Next.js frontend.

Qualifications

• Proven track record of taking ML models out of "notebook/experimentation" phases and into a live, scalable production environment.
• Experience overseeing the high-level strategy of a data science program, including defining the "common working language" and methodologies for the team.
• Formal data science training from a major university to ensure alignment on theoretical principles and industry standards.
• Deep experience in Python-driven backend development; ability to architect the logic that supports AI features.
• Familiarity with Google Cloud Platform tools for model hosting, data storage, and scaling.
• Experience managing the full Experiment, Deploy, Measure lifecycle, specifically using data to prove if a model change improved user outcomes.
• Proficiency in gathering, cleaning, and structuring data for specific AI use cases, such as RAG (Retrieval-Augmented Generation) for chat apps.
• Experience in a lead or senior role where you were responsible for delegating tasks and mentoring other engineers.
• Experience preparing slide decks and status reports for C-suite leadership to explain technical roadmaps and AI efficacy.
• Experience working within a multi-disciplinary product team (designers, frontend engineers, etc.) to integrate AI into a seamless user experience.
• Specific experience using feedback loops (e.g., human data correction processes, chat feedback) to continuously improve model performance based on real-world behavior.

Requirements

• The salary range for this role is $150,000 to $190,000 and applies only to jobs performed in Culver City, California.
• This range represents the lowest to highest salary we reasonably and in good faith believe we would pay for this role at the time of this posting.
• Please note that we may ultimately pay more or less than the posted range, and the range may be modified in the future.
• An employee’s position within the salary range will be based on several factors, including but not limited to relevant education, qualifications, certifications, experience, skills, geographic location, performance, and business or organizational needs.
