About Hedra

Hedra is a pioneering generative media company backed by top investors at Index, A16Z, and Abstract Ventures. We're building Hedra Studio, a multimodal creation platform capable of control, emotion, and creative intelligence.

At the core of Hedra Studio is our Character-3 foundation model, the first omnimodal model in production. Character-3 jointly reasons across image, text, and audio for more intelligent video generation its the next evolution of AI-driven content creation.

At Hedra, were a team of hard-working, passionate individuals seeking to fundamentally change content creation and build a generational company together. We value startup energy, initiative, and the ability to turn bold ideas into real products. Our team is fully in-person in SF/NY with a shared love for whiteboard problem-solving.

Overview

We are seeking a highly motivated Research Scientist to push the limits of long-form video generation, with a focus on auto-regressive modeling, causal attention mechanisms, and efficient sequence handling. The ideal candidate will have a deep understanding of temporal modeling in generative AI and experience building scalable architectures for multi-minute coherent video outputs.

Responsibilities

• Design and implement long video generation architectures, with emphasis on auto-regressive generation, causal attention, and memory-efficient transformer designs.
• Develop methods for maintaining temporal and semantic coherence over long time horizons.
• Work closely with engineering to integrate research into production-grade pipelines.
• Stay on top of recent advances in long-context transformers, sequence compression, and scalable video generation.
• Present results internally and externally, including possible top-tier conference submissions.

Qualifications

• PhD or strong research/industry experience in Computer Science, Machine Learning, or related fields, with a focus on sequence modeling or generative models.
• Deep understanding of transformer architectures, attention mechanisms, and auto-regressive modeling.
• Experience with long-context processing and memory-efficient computation.
• Proficiency in Python and PyTorch; ability to rapidly prototype and iterate on new architectures.
• A record of impactful research or large-scale system deployments.

Benefits

• Competitive compensation + equity
• 401k (no match)
• Healthcare (Silver PPO Medical, Vision, Dental)
• Lunch and snacks at the office

We encourage you to apply even if you don't meet every requirement we value curiosity, creativity, and the drive to solve hard problems.
