[Remote] Multimodal AI Engineer III

Note: The job is a remote job and is open to candidates in USA. Intelliswift, an LTTS Company, is seeking a Multimodal AI Engineer III to join their core team defining the future of multimodal AI. The role involves building data engines and evaluation platforms for multimodal LLMs, transforming raw data into benchmarks that drive breakthroughs, and collaborating with a team of scientists and engineers.

Responsibilities

• Design human and model-based datasets for training and evaluating MLLMs (image/video/audio/text data)
• Run frontier model evaluations and implement common metrics
• Use MLLMs to bootstrap, augment, and rebalance datasets
• Fine-tune models on labeled datasets
• Ship annotation task UIs and data-heavy internal tools (React/TypeScript)
• Run secure ingestion pipelines from warehouse/warm-storage/flat files at scale

Skills

• ML/AI fundamentals - fine-tuning (SFT/preference), prompting, model-based eval, and the failure modes of each
• At least one year of hands-on work in the field. Multimodal dataset experience - building image/video/audio/text datasets to train or evaluate models
• Strong Python + ML tooling - PyTorch (or equivalent), HF ecosystem, comfort running training/sampling jobs on real infra
• Web/UI engineering - production React/TypeScript; design, vibe code and ship clean, usable interfaces for annotation and internal tools
• Data pipelines - SQL plus reliable large-scale data movement: batching, idempotent dedupe, parallelism, retries
• Experience in mid sized tech, preference for (Google, Apple, Meta, or other FAANG)
• 5-10+ years of hands-on experience in building multimodal datasets, implementing machine learning evaluations, and developing production-level data and annotation tools
• Academic background in Computer Science, Engineering, or a related quantitative discipline
• MS or PhD in AI or related field
• Research track record in MLLMs - demonstrated through publications or impactful contributions to major projects
• Open-source contributions - experience shipping and maintaining public-facing repositories
