• Proficiency in one or more programming languages such as Java, C++, Go, or Python.
• Experience mentoring engineers and elevating technical standards.
• Demonstrated ability to use AI to improve the speed and quality of day-to-day engineering workflows, with a rigorous approach to testing, validation, and responsible use.
• Bachelor’s degree in Computer Science, a related technical field, or equivalent experience.

Preferred qualifications:

• Experience with ads delivery, recommendation or search serving, retrieval, ranking, or experimentation systems.
