General AI Specialist - PyTorch, MLflow, & Transformers

Project Brief

We are seeking a high-caliber AI Specialist to build and scale advanced machine learning systems. You will be responsible for developing state-of-the-art models using Deep Learning and Transformer architectures while ensuring absolute reproducibility through expert-level MLOps. This role is at the intersection of rigorous mathematics and elite engineering, focusing on creating elegant solutions to complex AI problems.

Location: Remote LATAM

Must-Haves

Machine Learning & Frameworks: Strong proficiency in PyTorch or TensorFlow/Keras and hands-on experience with the Hugging Face ecosystem (Transformers, Datasets, Accelerate).

MLflow Mastery: Expert knowledge of MLflow Tracking, Projects, and Models for full lifecycle management.

Engineering Excellence: Expert-level Python (OOP, asynchronous programming) and advanced Git workflows including DVC.

Core Mathematics: Deep theoretical understanding of the Attention Mechanism, Gradient Descent, and Linear Algebra.

Deployment & Tooling: Proficiency with Docker and building/securing REST/gRPC APIs for model serving.

Nice to Have

Generative AI: Familiarity with RAG architectures and vector databases such as Pinecone, Milvus, or Weaviate.

Advanced MLOps: Experience with MLflow Recipes for standardized production workflows and basic Kubernetes orchestration.

Efficiency & Scale: Experience with DeepSpeed, ONNX Runtime, or NVIDIA TensorRT, and knowledge of distributed training (Ray, Horovod, or DDP).

Cloud Platforms: Hands-on experience with AWS SageMaker, GCP Vertex AI, or Azure ML.

What You Will Do

Model Development: Design and implement Deep Learning models and Transformers, using classical ML (Scikit-learn, XGBoost) for baseline comparisons.

Standardize Workflows: Lead the implementation of reproducible ML environments using MLflow and Data Version Control (DVC).

Production Engineering: Build, profile, and secure high-performance APIs to serve models in production environments.

Cross-Functional Delivery: Work within 1-week sprints to move fast from research to delivery, ensuring robust and scalable AI solutions.

Why This Could Be Your Next Big Move

Work on Cutting-Edge Tech at Scale - This is a unique opportunity to join an elite digital product agency where you will apply deep mathematical concepts to real-world products. You will have high influence over the AI architecture and MLOps standards, working in a fast-paced environment that prioritizes technical excellence and elegant engineering. If you are looking to bridge the gap between research-level AI and production-grade delivery, this is the place to do it.
