# Large Language Model Intern [Razer](https://www.jorb.ai/firms/razer.md) · Singapore · [Machine Learning Engineering](https://www.jorb.ai/jobs/machine-learning-engineering.md) Razer is hiring a Large Language Model Intern in Singapore. Posted 2026-09-11; applications close 2026-11-10. **Apply**: https://razer.wd3.myworkdayjobs.com/Careers/job/Singapore/Large-Language-Model-Intern_JR2026007862 Posted 8d ago. ## Role details ## Job Responsibilities Train and optimize language models for Razer Software across the full pipeline—pretraining corpus construction, fine-tuning, evaluation, and deployment optimization. You will work with senior data scientists and engineers on the model powering Razer Synapse’s device assistant, 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 will 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: - Gain hands-on experience across the full LLM training lifecycle at production scale—not toy datasets - Develop practical judgment in data engineering: how cleaning/filtering/mixing decisions propagate into model quality - Run a rigorous ML experiment loop independently—hypothesize, train, evaluate, diagnose subtle regressions, and iterate - See how deployment constraints (on-device latency and memory on Razer Synapse hardware) shape training and architecture decisions, including compression, quantization, and distillation tradeoffs - Receive mentorship from senior engineers and visibility into how a production roadmap for a shipping AI feature is decided ## Candidate Requirements - **Education:** Current Bachelor’s, Master’s, or PhD student in Computer Science, 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, deduplication, 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, and top-tier publications (CVPR, NeurIPS, ICML, ACL, ICLR, EMNLP, etc.) ## Pre-Requisites Razer is proud to be an Equal Opportunity Employer. We believe that diverse teams drive better ideas, better products, and a stronger culture. We are committed to providing an inclusive, respectful, and fair workplace for every employee across all the countries we operate in.
