## About the role

TwelveLabs builds multimodal foundation models and products for multimodal intelligence and orchestration. The quality of those models and products depends on the quality of the data and evaluation work behind them, and that work depends on the internal tools the team uses daily. This role will own and build internal products to support model evaluation, regression testing, dataset discovery, and agentic context curation.

## What they're looking for

- Strong backend engineer with real depth in at least one language (Python, Go, or similar). You design data models, services, and APIs that hold up under real use
- Genuine system design instinct. You can take an ambiguous problem, decide what to build, and make architectural calls you can defend
- A track record of building zero to one internal products and shipping them
- Comfortable as the primary or sole engineer building the foundations for a larger team that can easily onboard onto what you’ve built
- Comfort owning a product outright: scoping it, building it, shipping it, and supporting internal users, while keeping sight of how it fits into science, product, and go to market
- Experience with large unstructured datasets
