Staff Software Engineer, Ads ML Inference InfrastructureThe Ads ML Inference Infra team owns the online inference and feature serving systems that power real-time model scoring and delivery for all Ads models at Pinterest. The team is looking for a staff engineer with strong hands-on experience in large-scale ML inference systems, as well as capabilities in solving ambiguous technical problems and driving strategic, cross-functional efforts.
What you'll do:- Lead and drive efforts to build next-generation model inference and feature serving systems that power up to 100x larger models and directly uplevel Pinterest's monetization business.
- Design and optimize low-latency, high-throughput inference pipelines to meet strict SLOs while improving performance, efficiency, and cost.
- Partner with Ads ML and product teams to productionize new model architectures (including LLMs and multi-stage ranking models) and scale them reliably to global traffic.
- Evolve the online feature platform (feature computation, caching, and retrieval) to improve coverage, freshness, and consistency for Ads models.
- Evaluate and integrate new technologies (e.g., GPU acceleration, model compression, Triton, vLLM, Dynamo) to advance our inference stack.
- Build strong partnerships with other infra and ML teams to improve end-to-end reliability, observability, and developer velocity for Ads ML.
- Mentor and coach other engineers, guiding them through technical decisions, system design, and career development.
What we're looking for:- BS (or higher) degree in Computer Science or a related field.
- ~8+ years of relevant industry experience designing and operating large-scale, production ML or distributed infra systems.
- Deep knowledge of at least one programming language (Java, C++, Python).
- Deep experience with distributed systems or recommendation / ads serving infrastructure (e.g., request routing, online storage, caching, feature serving, APIs).
- Hands-on experience with at least one deep learning framework (PyTorch or TensorFlow) and bringing models from offline experimentation to production.
- [Preferred] Experience with model / hardware accelerator libraries (e.g., CUDA, quantization, distillation, low-precision inference).
- [Preferred] Experience with inference optimization and serving frameworks such as Triton, vLLM, or Dynamo.
- Proven track record of leading complex projects, setting technical direction, and collaborating across functions and orgs; experience mentoring and coaching other engineers.
In-Office Requirement Statement:- We let the type of work you do guide the collaboration style. That means we're not always working in an office, but we continue to gather for key moments of collaboration and connection.
