About the Role:
Fetch is building the future of personalized consumer experiences. We’re looking for a Staff Machine Learning Engineer to serve as the technical lead for a high-impact ML team focused on personalization, relevance, and ranking.
In this role, you will own the technical direction and execution for your team’s ML systems - driving high-quality architecture, guiding implementation, and ensuring models and infrastructure operate reliably at scale. You’ll partner closely with product and cross-functional stakeholders while remaining deeply hands-on in design and development.
Role Responsibilities
  • Serve as the technical lead for a single ML-focused team, setting direction and raising the bar on engineering quality and system design.
  • Design, build, and scale ML systems supporting personalization, ranking, search, or ad-related use cases.
  • Own end-to-end architecture for your team’s services, including model training, evaluation, deployment, and serving.
  • Drive clarity in ambiguous problem spaces, translating product needs into scalable technical solutions.
  • Lead design reviews and ensure thoughtful tradeoffs around latency, reliability, experimentation, and maintainability.
  • Partner closely with product, data, and engineering stakeholders to deliver measurable business impact.
  • Mentor engineers through hands-on technical guidance, feedback, and example.
  • Use AI tools to accelerate development and improve system design, including:
    • Prototyping and validating ideas with LLM tools.
    • Leveraging AI for code iteration and experimentation.
    • Using AI assistants for architecture diagramming and design validation.
    • Exploring LLM-powered features where appropriate.
Minimum Requirements
  • 12+ years of industry experience in machine learning or software engineering, with demonstrated ownership of production ML systems operating at scale.
  • Proven experience building and scaling ML systems in personalization, relevance, search, or ad tech domains.
  • Strong hands-on expertise in distributed systems, data pipelines, and ML infrastructure.
  • Experience deploying ML models into production and operating them at consumer scale.
  • Demonstrated ownership of complex technical initiatives within a team.
  • Strong systems design skills with the ability to clearly articulate tradeoffs and implementation decisions.
  • Experience mentoring engineers and influencing technical standards within a team.
  • Ability to operate effectively in ambiguous environments and drive projects to completion.
  • Bachelor’s degree in Computer Science, Engineering, or a related technical field.
Preferred Requirements
  • Familiarity with LLMs and their application in personalization, feature generation, or search.
  • Experience with real-time or streaming ML systems.
  • Exposure to experimentation frameworks (A/B testing) and model performance measurement.
  • Experience bridging model development with real-time serving systems.
