Responsibilities

  • Collaborate with Keysight domain experts (RF, 6G-wireless, EM, circuit, and measurement) to gather requirements, physical constraints, and workflow insights for ML pipeline design.
  • Design and implement SOTA ML architectures including LLMs, agentic systems, GANs, diffusion models, and RAG pipelines for data augmentation, anomaly detection, modeling, and automation.
  • Develop scalable ML pipelines for on-device, on-prem, cloud, and hybrid GPU environments, ensuring efficiency, reliability, and scalability.
  • Write production-grade Python, C++, and CUDA code following best practices (testing, CI/CD, documentation, performance profiling).
  • Collaborate with product teams to integrate ML-driven features into Keysight’s commercial products.
  • Continuously explore and apply new research in LLMs, agentic reasoning, multimodal AI, and generative architectures to enhance Keysight’s capabilities.

Basic qualifications

  • Education: Master’s or PhD in Computer Science, Electrical Engineering, Applied Mathematics, or a related field.
  • Strong ML/DL foundations: solid understanding of neural architectures, optimization, and evaluation metrics.
  • Hands-on experience with PyTorch (preferred) or TensorFlow.
  • Proven expertise building or fine-tuning transformer architectures (GPT, T5, LLaMA, etc.).
  • Experience with LLM fine-tuning, instruction tuning, RLHF, PPO/DPO, or similar adaptation techniques.
  • Strong coding skills in Python and familiarity with CI/CD, testing, Git versioning, and containerization (Docker/Kubernetes).
  • Experience with data pipelines (tokenization, preprocessing, large text corpora).
  • Experience with MLOps tools (MLflow, Weights & Biases, Ray).
  • Experience with agentic workflows, RAG systems, or multimodal (text, code, signal) applications.
  • Excellent communication and teamwork skills; comfortable working in cross-functional R&D environments.
  • Familiarity with cloud environments (Azure, AWS, or GCP).
  • Experience optimizing models for edge or embedded environments.
  • Knowledge of model compression, quantization, or inference optimization.
  • Research literacy and the ability to read, reproduce, and extend SOTA papers.
  • Open-source contributions or public ML repositories are a strong plus.
  • Prior experience with Keysight software, test and measurement workflows, or domain-specific modeling is highly valued.
