What they need


  • This role focuses on designing and building agentic systems that power creative workflows for short-form video. You’ll help shape how AI agents reduce friction, accelerate learning, and unlock new creative possibilities for our users — building agents that can take creative actions on a user’s behalf — while experimenting with emerging models and techniques to bring these experiences to life in production
  • Software Engineers on the agents team work across product, machine-learning, and systems engineering — owning meaningful problems end-to-end and helping define how our agents are built and deployed across the product
  • Build and ship end-to-end agentic systems that meaningfully improve creative workflows, balancing quality, performance, and reliability
  • Design agent architectures — how agents gather context, plan, select tools, and execute creative tasks reliably at scale
  • Integrate state-of-the-art models, combining internal research and external capabilities to power new agent experiences
  • Measure and improve agent quality in production, using experimentation, evaluation frameworks, and real-world feedback to guide iteration

Benefits

  • Anything you need to do your best work
  • We’ve done team off-sites to places like Paris, London, Park City, Los Angeles, and Nashville with more planned in the future
  • Comprehensive medical, dental, and vision plans- While we don’t use hierarchical titles or levels internally, we are currently hiring engineers who have operated at senior or staff+ scope
  • Able to operate effectively in an extremely fast-paced environment and scope and deliver projects end-to-end
  • A track record of designing and developing ML systems or agentic pipelines in production
  • Experience building evaluation systems and agentic infrastructure (context gathering, tool selection, multi-step planning)
  • Exceptional problem solving fundamentals and ability to learn quickly in a rapidly evolving space
  • Deep experience with context engineering: RAG systems, token optimization, context management at scale
  • 5+ years of professional industry experience
  • You have worked with multi-agent architectures
  • You have experience fine-tuning LLMs for specific use cases
  • You have a pulse on where generative media and agentic AI technology is going
  • You are grounded, collaborative, and willing to do whatever it takes to help the team win
  • You have been a startup founder or an early engineer at one
