- Reddit is building a dedicated Ads ML Efficiency function to make model training and inference materially faster, cheaper, safer, and more scalable.
- As the Engineering Manager for this team, you will lead a group focused on model optimization, training efficiency, GPU enablement, load testing, model performance tooling, and efficiency guardrails across Ads ML.
- This role sits at the intersection of ML modeling, systems optimization, and organizational leverage.
- You will partner closely with ranking teams, ML Platform teams and serving owners to identify the highest-value bottlenecks, land measurable efficiency wins, and build the tooling and operating mechanisms that make those wins repeatable. What you’ll do:
- Set Technical Direction: Define the roadmap for training optimization, inference optimization, launch-readiness tooling, and reusable efficiency primitives across Ads ML.
- Raise the Bar: Establish engineering rigor around measurement, performance debugging, launch safety, and technical decision-making for efficiency work. What we’re looking for: Deep ML Engineering
- experience improving training loops, serving systems, profiling workflows, model/inference efficiency, or GPU utilization.
- Distributed Systems Fluency: Proven ability to reason about production-scale ML systems and the tradeoffs that govern reliability, speed, cost, and scale.
- Experience in ads ranking, recommender systems, marketplace ML, or adjacent production ML domains is strongly preferred. Nice-to-have: •
- Experience with GPU training and serving migrations. •
- Experience with PyTorch, distributed training frameworks, or kernel/performance optimization. •
- Experience building efficiency benchmarking or launch certification frameworks. •
- Experience working in organizations where ML platform and applied modeling
- Additionally, Reddit offers a wide range of
- In select roles and locations, the interviews will be recorded, transcribed and summarized by artificial intelligence (AI).
