About the role

Key responsibilities & impact

Design, implement, and maintain end-to-end ML training pipelines — from raw data ingestion and preprocessing through model training, evaluation, and deployment.
Fine-tune large language models using techniques such as LoRA, QLoRA, and full fine-tuning; apply PEFT strategies to balance performance and compute cost.
Implement and experiment with reinforcement learning from human feedback (RLHF) workflows, including PPO (Proximal Policy Optimization) and GRPO (Group Relative Policy Optimization) for model alignment and preference optimization.
Host, serve, and optimize LLMs in production using inference frameworks such as vLLM, Text Generation Inference (TGI), Triton Inference Server, or ONNX Runtime.
Evaluate, benchmark, and select inference providers (e.g., Together AI, Fireworks, Groq, Replicate, AWS Bedrock, Azure OpenAI) based on latency, cost, throughput, and model capability trade-offs.
Build and maintain embedding pipelines — generate, index, and retrieve dense embeddings using vector databases (Pinecone, pgvector, Weaviate, or similar) for RAG and semantic search applications.
Implement and expose ML capabilities via Model Context Protocol (MCP) — enabling AI agents to call model-backed tools in a structured, context-aware manner.
Perform rigorous data analysis and processing: clean, transform, and curate datasets for training, fine-tuning, and evaluation; build data quality and validation pipelines.
Develop robust model evaluation frameworks — define metrics, build eval harnesses, run A/B experiments, and track regressions across model versions.
Collaborate with software engineers to integrate ML systems into product features via FastAPI services; ensure models are observable, versioned, and maintainable in production.

Requirements

What you’ll need

Bachelors in computer science or statistics
3–8+ years of hands-on ML engineering experience with a strong production track record.
Deep understanding of core ML concepts: neural network architectures (transformers, attention mechanisms), loss functions, optimization algorithms, regularization, and model evaluation.
Practical experience fine-tuning LLMs (LoRA, QLoRA, PEFT, instruction tuning, DPO) on custom datasets using frameworks such as Hugging Face Transformers, TRL, or Axolotl.
Hands-on experience with RL-based alignment techniques — specifically PPO and GRPO — for reward modeling, preference optimization, and RLHF pipelines.
Experience hosting and serving LLMs: vLLM, TGI, Triton, or similar; understanding of model quantization (GPTQ, AWQ, int4/int8), batching strategies, and throughput optimization.
Working knowledge of major inference vendors and cloud AI APIs; ability to evaluate and select providers based on cost, latency, and capability benchmarks.
Proficiency in embedding models (sentence-transformers, OpenAI embeddings, or equivalent) and vector search infrastructure for RAG pipelines.
Understanding of Model Context Protocol (MCP) and how to expose ML functionality as structured tools for agentic systems.
