Descrição

• Build and improve production generative systems for AI-generated motion from natural language • Improve prompt interpretation, model orchestration, routing, retrieval, tool use, structured generation, validation, repair, and visual verification • Diagnose recurring failure modes and implement durable improvements in prompts, data, system logic, constraints, or evaluation • Build compiler-backed feedback loops and deterministic quality gates • Develop experiments and fixed evaluation batteries to measure output-quality improvements • Design supervised fine-tuning datasets, training recipes, and post-training experiments for direct Motion DSL generation • Explore distillation, preference optimization, synthetic-data generation, reinforcement-learning approaches, and constrained generation • Select model checkpoints using evaluations of correctness, visual quality, reliability, latency, and cost • Determine whether model failures should be addressed through data, training, inference, evaluation, or the language/runtime • Convert production generations into training and evaluation datasets using filtering, provenance, versioning, deduplication, and contamination controls • Design train, validation, and evaluation splits that minimize leakage and preserve meaningful generalization tests • Create failure taxonomies, hard negatives, regression suites, and representative prompt batteries • Combine deterministic checks, model-based judges, render evidence, and human review into a reliable evaluation system • Own engineering work end-to-end with measurable product impact

🎯 Requisitos

• Strong ML and software engineering experience • Built and operated production AI or machine-learning systems, not only prototypes • Comfortable working across model behavior, data pipelines, APIs, infrastructure, evaluation, and product code • Practical experience with supervised fine-tuning and modern post-training workflows • Understanding of how dataset construction affects model behavior • Ability to prevent leakage, contamination, and misleading evaluation results • Ability to design experiments, regression suites, automated graders, and evaluation datasets • Experience with code-generation models, DSLs, grammars, parsers, compilers, structured outputs, constrained decoding, or program synthesis is especially relevant • Production engineering judgment involving observability, reliability, latency, inference cost, caching, failure recovery, and maintainability • Experience with animation, motion design, graphics, creative tooling, or multimodal systems is valuable but not required • Nice to have: experience fine-tuning or evaluating code-generation models • Nice to have: experience with multimodal or vision-language models • Nice to have: experience building model-based, human-in-the-loop, or rubric-driven evaluation systems • Nice to have: experience with compilers, interpreters, language tooling, or program analysis • Nice to have: experience with Rust, PyTorch, or distributed training infrastructure • Nice to have: experience with preference optimization, reinforcement learning, or synthetic-data pipelines • Nice to have: experience with animation, graphics, rendering, or creative software

🏖️ Benefícios

• Fully Remote Working Environment • Flexible Work Hours • A welcome gift and LottieFiles swag pack • Bonus to set up your workstation at home • Unlimited Leave Days • Medical Insurance • Generous learning budget • Gym membership • Co-working space membership
