About the Job

Requirements

  • PhD or MSc in Computer Science, Machine Learning, or a related field.
  • At least 5 years of experience as an AI/ML researcher with shipped research artifacts, including at least 2 years building LLM-based systems.
  • Experience running multi-stage training pipelines, including pretraining, fine-tuning, and post-training, and diagnosing training failures from loss curves, gradient norms, and evaluation metrics.
  • Deep expertise in at least one of domain-specific model adaptation, multimodal learning, reinforcement learning from human feedback, knowledge-grounded generation, or retrieval-augmented systems, with published or shipped production work in that area.
  • Hands-on experience with distributed training at scale using DeepSpeed, FSDP, Megatron-LM, or equivalent; understanding of data parallelism and model parallelism and when each is appropriate.
  • Production-grade Python skills, clean abstractions, and tested code; ability to build tools others depend on.

Responsibilities

  • Own and orchestrate end-to-end research programs using massively parallel agentic AI, from problem formulation through production deployment, designing agent-driven experiment campaigns to explore model architectures, training regimes, data strategies, and evaluation criteria in parallel.
  • Drive domain-specific model quality by leading multi-stage training pipelines, domain adaptation, reinforcement-learning-based optimization including RLHF, DPO, and reward modeling, and training-dynamics analysis; use agentic systems for ablations, hyperparameter sweeps, and failure-mode investigations.
  • Design and train multimodal systems spanning text, images, tables, charts, and technical documents, as well as knowledge-graph pipelines, hybrid retrieval architectures, and structured reasoning systems; delegate exploration and prototyping across parallel agent workflows and synthesize cross-cutting insights.
  • Build agent-orchestrated infrastructure for domain-specific data curation, quality filtering, preprocessing, and large-scale training that the research team can use.
  • Mentor AI Researchers on designing effective agent workflows to increase their research depth and breadth.
  • Move prototypes to production-ready systems using agentic continuous integration and continuous delivery, automated integration testing, and continuous evaluation harnesses, in collaboration with engineering, product, and domain experts.
  • Document findings, publish at top-tier venues, and contribute to internal knowledge infrastructure that agentic tools can index and reason over.
  • Identify bottlenecks in individual and team workflows and design or adopt efficient, scalable solutions to address them.

Desired Qualifications

  • Experience adapting models to specialized domains where standard benchmarks do not apply, including defining correctness and building evaluation around it.
  • Track record of taking a research prototype to a production system serving real users.
  • Practical experience with knowledge-graph construction, hybrid retrieval architectures, or structured reasoning systems.
  • Strong publication record demonstrating depth.
  • Experience with cloud-native machine-learning infrastructure, including Kubernetes, distributed job scheduling, or GPU cluster management.
