  • Large Language Model Expertise: Leverage large language models (LLMs) to create scalable, intelligent solutions for content understanding, user engagement, and relevance ranking
  • Experimentation and Analysis: Drive data-driven experimentation using A/B testing, advanced analytics, and statistical techniques to identify growth opportunities and refine algorithms
  • Infrastructure Optimization: Develop and optimize pipelines, tools, and infrastructure to support real-time decision-making, personalization, and predictive analytics
  • Technical Leadership: Mentor team members and foster collaboration within cross-functional teams, including engineers, product managers, and designers
  • Continuous Innovation: Stay informed on emerging trends in AI and machine learning, and integrate them to drive innovation and improve product offerings
  • Cross-functional Collaboration: Articulate findings and recommendations to technical and non-technical audiences, influencing decisions across teams and leadership
  • Embody our Culture and Values

Requirements

  • Bachelor's Degree in Computer Science, or related technical discipline AND 4+ years technical engineering experience with coding in languages including, but not limited to, C, C++, C#, Java, JavaScript, or Python OR equivalent experience
  • 3+ years of experience building and deploying ML models in production environments
  • Strong coding skills in Python and experience with ML frameworks (e.g., PyTorch, TensorFlow)
  • Familiarity with data processing tools (e.g., Spark, Pandas) and cloud platforms (e.g., Azure, AWS)
  • Experience with classification, recommendation, or personalization systems
  • Experience using large language models (LLMs) for machine learning and AI applications
  • Hands-on experience in growth engineering, driving improvements in user acquisition, engagement, and retention
  • Hands-on experience with machine learning frameworks such as TensorFlow, PyTorch, or Scikit-learn
  • Expertise in personalization strategies and user behavior modeling
  • Strong problem-solving skills and the ability to independently design solutions to complex challenges
  • Excellent communication skills, with the ability to influence technical and non-technical audiences
  • Ability to work in a fast-paced environment, manage multiple priorities, and adapt to changing requirements and deadlines
