Overview

We run an AI guardrails platform — a pipeline of 20+ validators that screen text, images, documents for safety and compliance risks (toxicity, PII, NSFW, violence/self-harm, jailbreak, prompt injection, copyright, brand, language, anomaly/zero-day). Today many validators rely on external LLM/vision APIs. Your job is to build the guardrail system and ship our own models so each validator runs on…
Fine-tune models for validators — intent, toxicity, sensitive topic, jailbreak, prompt injection, PII, NSFW/violence...detectors, language and anomaly detectors and embeddings for retrieval.
Build the model pipeline — data prep → training → evaluation (precision/recall per validator) → serving, with iteration driven by metrics, not vibes.
Optimize for serving — quantization, distillation, ONNX/TensorRT/vLLM, latency-vs-accuracy trade-offs so validators run fast at scale.
Build the backend that wraps each model behind APIs — request routing, batching, async, caching, logging.
Build the web frontend for configuration, validator results, evaluation, and analytics dashboards.
Handle multimodal — image and document inputs (transcription, OCR → downstream classifiers).

We're looking for
5+ years in software, with real time spent training/tuning models or building generative AI applications.
Hands-on fine-tuning of transformer models — classifiers, embeddings. You can take a base model, prepare data, train, evaluate, and deploy.
ML & NLP frameworks — PyTorch, TensorFlow, Hugging Face, spaCy, nltk, scikit-learn. Fluent in datasets, training loops, eval, and checkpointing. Familiar with MLOps
Solid backend — Golang, Python (FastAPI/Flask), APIs, queues, databases, model serving.
Data discipline — labeling, cleaning, augmentation, versioning, and honest evaluation.
Deployment — Docker, a cloud (AWS/GCP), CI for both code and models.
Nice to have
Production content-moderation / safety experience.
Model serving optimization — quantization, ONNX, vLLM, TensorRT.
Multimodal work — image/audio/video classification.
Information retrieval / search / RAG.

Flexible working hours and attendance policy (Work from Home on working Saturdays).
Attractive compensation and bonus packages, highly competitive in the market.
Exclusive employee benefits across the Group’s ecosystem in accordance with company policies.
Opportunity to work on large-scale and strategic technology projects.
Professional technology environment with leading scientists, experts, and engineers from top technology companies in Vietnam and around the world.
Free access to learning platforms such as Udemy, Coursera, and O’Reilly; internal workshops; sponsorship for professional certifications; and exclusive mentoring programs from the Group and Company leadership team.
Full statutory insurance coverage in accordance with Vietnamese Labor Law (Social Insurance, Health Insurance, Unemployment Insurance), along with private healthcare insurance based on job grade and annual health check-ups at reputable hospitals and healthcare centers nationwide.
Participation in internal activities, team-building programs, and annual company events.
