Original job description

About The Role

We are looking for a Software Intern to help us adapt open-weight large language models to security and identity work. You will take a model from raw data to a measured result: preparing datasets, running fine-tuning jobs, and building the evaluations that tell us whether a change helped.

This is a Fall/Winter internship: hands-on work with real models and real GPUs, alongside the founding team. If you have already fine-tuned a model and want to do it on problems that matter, this is the role for you.

Responsibilities

What you’ll own.

Data & training

Collect, clean, and prepare training and evaluation datasets.
Fine-tune open-weight LLMs with SFT and parameter-efficient methods (LoRA / QLoRA).
Run and monitor training jobs on GPUs, and make the most of limited compute.

Evaluation

Build evaluation sets and benchmarks that reflect the tasks we care about.
Compare models and training runs, and report clearly what worked and what did not.

Required Skills

What you’ll bring day one.

Core

PyTorch and the Hugging Face ecosystem (Transformers, Datasets, PEFT).
Hands-on experience with open-weight LLMs.
Fine-tuning: SFT, LoRA / QLoRA.
Dataset preparation for training and evaluation.
Model evaluation.
GPU fundamentals: memory, batch sizes, mixed precision.

Nice to Have

Domain-adaptive or continued pretraining (DAPT).
Synthetic data generation.
CUDA.
Docker.
vLLM for serving and fast inference.
Experiment tracking (Weights & Biases, MLflow or similar).
Evaluation frameworks and harnesses.
Reinforcement learning for LLMs.

Why Join Us

01

Train and evaluate real models, not a sandbox project.

02

Work directly with the founding team.

03

Learn how AI meets security and cryptographic identity.

Responsibilities

Prepare training and evaluation datasets, fine-tune open-weight LLMs using supervised and parameter-efficient methods, and run and monitor GPU training jobs. Build benchmarks, compare models and training runs, and clearly report evaluation results.

Requirements

Candidates should have hands-on experience with open-weight LLMs, PyTorch, the Hugging Face ecosystem, fine-tuning methods such as SFT and LoRA/QLoRA, and dataset preparation and model evaluation. They should understand GPU fundamentals, including memory, batch sizes, and mixed precision; experience with domain-adaptive pretraining, synthetic data, CUDA, Docker, vLLM, experiment tracking, evaluation frameworks, or LLM reinforcement learning is a plus.
