• Improve the serving stack through framework modernization, API evolution, experimentation controls, observability, and debugging tools.


• Lead complex projects end to end: technical strategy, design, implementation, rollout, adoption, and operational readiness.


• Use AI to accelerate analysis, debugging, design exploration, and iteration while applying sound engineering judgment and validation.


• Raise the quality bar through design reviews, code reviews, documentation, and operational excellence.


• Mentor engineers and scale technical leadership across the organization.

What we’re looking for:

• 8+ years of software engineering experience building and operating production backend or distributed systems.


• Experience leading complex technical initiatives across teams or organizations.


• Strong expertise in distributed systems, online serving, low-latency services, or infrastructure platforms.


• Demonstrated ability to make sound tradeoffs across latency, reliability, scalability, cost, and developer experience.


• Strong communication and collaboration skills with technical and cross-functional partners.


• 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.
  
  
  • Experience with serving-framework migrations, platform consolidation, or developer tooling.
