Principal Applied Research Engineer

Role overview

As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations. Our goal is to get to human centric video models that can generate arbitrary long videos at high resolution with arbitrary actions and events. What you'll doOwn the end-to-end technical direction for offline video generation, spanning pre-training and post-training, resolving the artificial boundary between those two stages in service of shipping better models faster. You'll thrive in this role if you haveA proven track record training large-scale video generation models from scratch, across multiple nodes, at the scale of millions of hours of data.

What you'll do

• Own the end-to-end technical direction for offline video generation, spanning pre-training and post-training, resolving the artificial boundary between those two stages in service of shipping better models faster.
• Partner with research leadership and team leads to define a unified long-term roadmap, broken into achievable objectives, and drive execution against it.
• Identify the most critical technical gaps across the video generation pipeline and jump in to unblock them, whether that means architectural decisions, training stability, post-training alignment, or cross-team coordination.
• Increase the velocity at which research ships to product: accelerate problem-solving, improve research-to-production handoffs, and increase visibility of research output in partnership with PMs.
• Coach and elevate more junior researchers and engineers toward senior technical thinking and execution.
• Help shape team structure and refine processes to enable high-velocity, cohesive execution across research.
