Senior AI Engineer

Remote, Worldwide

About the role

We are building AI systems that generate production-quality motion from natural language. The system combines frontier language models, an AI generation harness, and a text-native Motion DSL designed for structured, editable animation.

This role spans two connected areas: improving the production generation system used today, and developing specialized models that can generate the Motion DSL directly with higher quality, lower latency, and better cost efficiency.

You will work at the intersection of LLM systems, post-training, code generation, compilers, evaluation, data engineering, and motion design. This is a hands-on engineering role with end-to-end ownership and measurable product impact.

Key Responsibilities

Build and improve production generative systems

Design and ship improvements across prompt interpretation, model orchestration, routing, retrieval, tool use, structured generation, validation, repair, and visual verification.

Diagnose recurring failure modes and turn them into durable improvements in prompts, data, system logic, constraints, or evaluation.

Build compiler-backed feedback loops and deterministic quality gates that prevent invalid or...
