About the role
- At Pika, we are pioneering the next generation of creative infrastructure built around real-time, multimodal generation and intelligent agentic platforms.
- We are seeking Research Scientists with expertise in RL post-training and generative modeling for large-scale video generation.
- Distillation of RL-tuned models is a secondary focus.
Responsibilities
- Build video reward models: define target evaluation dimensions, design/configure preference data collection workflows, train and validate learned judges, and safeguard against reward hacking.
- Own post-training evaluation, including human preference studies and their correlation with automated metrics.
- Experience developing reward models for visual generation, including VLM-as-judge or large-scale preference data collection.
- As a key member of our research team, you will own RL-based post-training for video diffusion/flow-matching models, develop state-of-the-art reward models, and lead post-training evaluation across human and automated metrics.
- You will collaborate closely with engineering and product teams, shaping the frontier of real-time creative and agentic video platforms.
- RL alignment of Pika's video generation models and the reward models that drive them.
- Pika empowers creators by building state-of-the-art agentic and multimedia platforms.
Requirements
- 2+ years hands-on research experience in post-training or generative modeling.
- Distillation expertise (distribution matching, consistency, adversarial approaches), ideally for video models.
- Familiarity with video-specific failure modes: temporal drift, motion and physics realism.
Compensation
- Competitive salary and substantial equity in a high-growth startup
Benefits
- Competitive salary and substantial equity in a high-growth startup
- Full health benefits + 401k matching and more
- Our vision is to break down technical barriers to creativity, making real-time generative and intelligent orchestration accessible to all.
- Flexible on-site/remote hybrid (HQ in Palo Alto, CA)
