Large Language Model Intern

Joining Razer will place you on a global mission to revolutionize the way the world games. Razer is a place to do great work, offering you the opportunity to make an impact globally while working across a global team located across 5 continents. Razer is also a great place to work, providing you the unique, gamer-centric #LifeAtRazer experience that will put you in an accelerated growth, both personally and professionally.

Job Responsibilities :

Train and optimize language models for Razer Software, across the full pipeline — pretraining corpus construction, fine-tuning, evaluation, and deployment optimization.

Job Scope

You'll work with senior data scientists and engineers on the model powering Razer Software, covering the full training pipeline:

• Corpus construction — cleaning, filtering, deduplication, and mixing of training data

• Fine-tuning — SFT, LoRA, and preference optimization runs

• Evaluation — quality, latency, and memory benchmarking against production constraints

• Deployment optimization — compression and quantization experiments for on-device targets

You'll own discrete workstreams end-to-end (design → run → debug → analyze → iterate) rather than executing isolated tasks handed down by a mentor.

Learning Objectives

By the end of this internship, you will have:

• Hands-on experience across the full LLM training lifecycle at production scale — not toy datasets

• Practical judgment in data engineering: how cleaning/filtering/mixing decisions propagate into model quality

• The ability to independently run a rigorous ML experiment loop — hypothesize, train, evaluate, diagnose subtle regressions, iterate

• Direct exposure to how deployment constraints, shape training and architecture decisions, including compression, quantization, and distillation tradeoffs

• Mentorship from senior engineers and visibility into how a production roadmap for a shipping AI feature actually gets decided.

Candidate Requirements

• Education: Current Bachelor's, Master's, or PhD student in CS, AI, Data Science, or a related field

• Must-have knowledge: LLM training paradigms (pretraining, SFT, LoRA, preference optimization); Transformer/deep learning fundamentals; how deployment constraints (latency, memory) shape training decisions

• Must-have skills: Python; hands-on PyTorch model training; data engineering for training corpora (cleaning, filtering, dedup, mixing); end-to-end experiment running (debugging, hyperparameter tuning, analysis); benchmarking quality/latency/memory

• Nice-to-have: Model compression (quantization, distillation), distributed training (multi-GPU/parallelism), Hugging Face/Accelerate/DeepSpeed, Linux environment

• Screening bar (hard requirement): Demonstrable hands-on model training/fine-tuning experience (coursework, research, internship, or open source). API-calling or prompt-engineering-only experience does not qualify.

• Strong positives: Trained a model from scratch (any scale), multi-GPU training, model compression/on-device deployment work, top-tier publications (CVPR, NeurIPS, ICML, ACL, ICLR, EMNLP, etc.)
