Senior Applied GenAI Video Engineer

About Us Atria is an AI-powered ad creative workflow platform designed to help marketing teams generate more revenue by producing winning ads more efficiently.

About the role You'll own the end-to-end video generation pipeline that powers ad creative production — from vendor selection and prompt/media orchestration to scalable serving, quality evaluation, and reliability in production. This is a hands-on engineering role focused on shipping systems that move business metrics, not just prototypes. What you'll do • Build and own video generation pipelines: prompt orchestration, asset conditioning, shot assembly, rendering, post-processing, and delivery. • Translate product goals (better-performing ad creatives, faster iteration) into measurable GenAI outcomes (quality, CTR lift proxies, latency, cost). • Integrate external video GenAI vendors/APIs and manage versioning, fallbacks, quotas, and reliability. • Create evaluation frameworks for video quality and ad readiness. • Optimize for latency, throughput, and cost (caching, batching, retries, parallelism, content aware routing). • Partner with product/design/engineering to ship improvements quickly and safely. What we're looking for • Experience building production video GenAI systems • Strong engineering skills: Python, solid software design, testing, code reviews, performance tuning. • Practical understanding of LLMs and multimodal prompting: prompt design, tool/function calling patterns, structured outputs, guardrails. • Familiarity with DevOps: CI/CD, containers, experiment tracking, monitoring/alerting, cloud deployment. • Comfort with at least one major cloud: AWS/GCP/Azure. • Able to communicate clearly in English (technical documentation and collaboration).
