# Machine Learning Engineer

**Company:** [Cantina](https://hotfix.jobs/companies/cantina)
**Location:** Unspecified
**Role:** ML Engineering
**Skills:** Python, Pyspark, Ray, Airflow, Docker, Kubernetes, AWS, GCP, Azure, Vlms, Clip, Ffmpeg, Pyav, Opencv, PyTorch
**Posted:** 2026-05-12

> Build and scale distributed pipelines that ingest, curate, filter, and prepare large-scale video and multimodal datasets for model training. The role requires Python, distributed processing, orchestration, containers, cloud infrastructure, and experience with VLM-based captioning or data-quality workflows.

## Job Description

## Responsibilities
- Design and scale distributed data pipelines for preprocessing, dataset generation, and repeated dataset refreshes.
- Own workflow orchestration, job scheduling, monitoring, and failure recovery for large-scale data processing jobs.
- Implement and maintain containerized pipeline infrastructure using Kubernetes or equivalent orchestration systems.
- Optimize cloud-based data storage and movement across providers for cost, throughput, and operational efficiency.
- Define and implement best practices for dataset storage layout, versioning, caching, retention, and access patterns.
- Design and implement curation pipelines to select, filter, and retain video and image content for model training, including image-text pair datasets for joint training regimes.
- Build and improve VLM-based captioning and metadata-generation workflows at scale across video and image data.
- Develop and apply quality and aesthetic scoring models, CLIP-based semantic filtering, and other signal-extraction approaches for data selection.
- Build tooling for large-scale deduplication workflows, including near-deduplication and exact deduplication over large video corpora.
- Analyze dataset composition, identify quality issues, and iterate on curation logic to improve training outcomes.
- Define and evolve standards for high-quality, training-ready video data across different training regimes.

## Requirements
- Strong hands-on experience building or scaling large-scale machine-learning data systems and pipelines, including dataset curation, filtering, and quality improvement.
- Experience with distributed data-processing frameworks such as PySpark or Ray, and workflow orchestration tools such as Airflow or equivalent.
- Familiarity with containerization and container orchestration, including Docker and Kubernetes.
- Experience with cloud-based data storage and compute, including AWS, GCS, and/or Azure, and tradeoffs involving cost, throughput, storage layout, and access patterns.
- Experience with VLM-based captioning pipelines or quality/aesthetic scoring models for video or image data, including curation of image-text pair datasets for joint image-video training.
- Familiarity with CLIP-based or embedding-based filtering and semantic data-selection techniques.
- Familiarity with video and media-processing tools such as FFmpeg, PyAV, DALI, or OpenCV, and libraries such as Decord, torchvision, PyTorchVideo, or torchaudio.
- Proficiency in Python.
- Strong problem-solving, communication, and documentation skills.

## Benefits
- Competitive salary and generous company equity.
- Personal time off and paid holidays.
- Health insurance.
- Global travel insurance covering international travel.
- Monthly spending stipend of $500 (~S$635).
- Equipment provided for a home office.
