# AI Engineer
**Company:** [Vooma](https://hotfix.jobs/companies/vooma)
**Location:** San Francisco, CA
**Skills:** LLMs, Multimodal Models, Fine-Tuning, RLHF, Synthetic Data Generation, Active Learning, Python, TypeScript, Next.js, GraphQL, OpenAI, Anthropic
**Posted:** 2026-04-20
> Builds, fine-tunes, and deploys multimodal AI models and agents for trucking logistics automation. Owns full ML lifecycle including data flywheels, evaluation, production adaptation, using Python, TypeScript, and leading AI APIs.
## Job Description
## Responsibilities
- Training, fine-tuning, and deploying state-of-the-art multimodal models across a range of real-world tasks
- Designing and implementing evaluation frameworks to rigorously measure model performance and guide iteration
- Building and scaling data flywheels - collecting, curating, and generating high-quality datasets to continuously improve model outcomes
- Developing systems for live learning, feedback incorporation, and continuous model adaptation in production
- Implementing techniques like negative mining to harden models against edge cases and failure modes
- Owning the full lifecycle from experimentation → validation → deployment → monitoring
- Collaborating closely across engineering and product to integrate models into reliable, high-performance systems

## Requirements
- Hands-on experience working with modern foundation models (**LLMs**, multimodal models, or similar) in production settings
- Strong intuition for model behavior, evaluation, and failure modes
- Experience with fine-tuning, training pipelines, and dataset construction
- Familiarity with techniques like **RLHF**, synthetic data generation, or active learning (not required, but highly relevant)
- Comfort working across **Python**-based ML stacks and **Typescript**-based production systems
- A bias toward action - you run experiments, measure results, and iterate quickly
- The mindset of an owner: you care about outcomes, not just outputs, and push systems to actually work in the real world

## Tech Stack
- **Next.js**, **GraphQL**, **Node**, **OpenAI**, **Anthropic**
