• Ensure flawless completion of projects through strict attention to detail and proven methodologies.

What we need to see:

• Bachelor’s degree in Computer Science, Engineering, or equivalent experience.

• Experience in utilizing model customization tools: LoRA, QLoRA, supervised fine-tuning (SFT), reinforcement learning (RL), preference optimization (e.g., DPO), and retrieval-augmented generation (RAG)

• 7+ years of experience with LLM serving infrastructure (vLLM, TRT-LLM, or equivalent).

• Deep understanding of model quantization and fine-tuning workflows.

• Demonstrated history of developing robust platform APIs.

• Strong collaborative skills and experience working in cross-functional teams.

• Outstanding problem-solving skills and meticulous attention to detail.

Ways to stand out from the crowd:
