General Summary:

We are seeking a highly skilled Core ML Engineer to design, develop, and optimize machine learning systems that power next-generation AI platforms and applications. This role focuses on model development, inference optimization, and scalable ML infrastructure, enabling production-grade AI capabilities across enterprise systems.

The ideal candidate combines strong software engineering fundamentals with deep ML expertise, and thrives in building robust, high-performance systems at scale.

Key Responsibilities

• Core ML System Development
  • Design and implement machine learning models and pipelines for production use
  • Build scalable training → evaluation → deployment workflows
  • Develop reusable ML components, libraries, and frameworks

• Inference & Performance Optimization
  • Optimize model inference for latency, throughput, and cost
  • Implement advanced techniques such as caching, quantization, batching, and routing
  • Benchmark and profile models across diverse workloads and hardware environments

• Model Integration & Deployment
  • Integrate ML/LLM models into APIs, microservices, and applications
  • Build and maintain model-serving infrastructure (e.g., vLLM, ONNX, custom runtimes)
  • Collaborate with platform and infrastructure teams for scalable deployment

• Data & Pipeline Engineering
  • Design data pipelines for ingestion, preprocessing, feature engineering, and validation
  • Improve data quality and model reliability through systematic evaluation

• Cross-functional Collaboration
  • Partner with product, platform, and hardware teams to deliver end-to-end ML solutions
  • Participate in design reviews and contribute to system architecture decisions

Minimum Qualifications:

Preferred Qualifications

Strong programming skills in Python and at least one systems language (C++/Rust/Go)

Solid understanding of:

• Machine learning fundamentals (supervised, unsupervised, deep learning)
• Transformer architectures / LLMs
• Model evaluation and debugging

Experience with:

• ML frameworks (PyTorch, TensorFlow)
• Model deployment and serving systems
• Building scalable software and APIs

Experience with:

• Large Language Models (LLMs), multimodal models, or generative AI
• Retrieval systems and RAG pipelines
• Distributed computing and GPU/accelerator environments including model serving and efficient cache/state management (e.g. KV cache, embeddings) across disaggregated systems
• Kubernetes, Docker, and CI/CD pipelines
• Agentic and multi-step AI workflows, tool integration, orchestration, and multi-component pipelines

Knowledge of:

• Model optimization techniques (quantization, distillation, caching)
• Vector databases and search systems (OpenSearch, Qdrant, etc.)
• Cost-aware system design - model routing (small vs. large models), dynamic batching, and caching strategies
