Senior Applied AI Researcher (Brazil)

The role

You will own end-to-end research projects from problem formulation to production deployment. This role involves model training, reinforcement learning, multimodal understanding, and knowledge representation.

What you will do

• Orchestrate end-to-end research programs using massively parallel agentic AI
• Drive domain-specific model quality through multi-stage training pipelines and RL-based optimization
• Design and train multimodal systems, knowledge graph pipelines, and hybrid retrieval architectures
• Architect agent-orchestrated pipelines for data curation and large-scale training
• Mentor AI Researchers in the agentic paradigm
• Take prototypes to production-ready systems using agentic CI/CD
• Document findings and publish at top-tier venues
• Identify and design solutions to eliminate workflow bottlenecks

Required qualifications

• PhD or MSc in Computer Science, Machine Learning, or a related field
• 5+ years as an AI/ML researcher with shipped research artifacts
• 2+ years building LLM-based systems
• Experience running multi-stage training pipelines and diagnosing training failures
• 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
• Published or shipped production work in your area of expertise
• Hands-on experience with distributed training at scale (DeepSpeed, FSDP, Megatron-LM, or equivalent)
• Production-grade Python and clean abstractions

Nice to have

• Experience adapting models to specialized domains where standard benchmarks don't apply
• Track record of taking a research prototype to a production system serving real users
• Experience with knowledge graph construction, hybrid retrieval architectures, or structured reasoning systems in practice
• Strong publication record with evidence of depth
• Cloud-native ML infrastructure experience (Kubernetes, distributed job scheduling, GPU cluster management)
