Senior Software Engineer, Agent

About the Role

We are building the next-generation AI-powered platform and web application for easy and fast creation of audio and video content. Building a revolutionary way to record, transcribe, edit, and mix audio and video on the web comes with a series of unique technical challenges and requires solving hard and complex problems. We are hiring Software Engineers at the senior and staff levels to join a few open roles on our Agent team, focused on building the future of Agentic Video Editing!

About the team:

Descript's Agent launched in Open Beta in July 2025. Since then, we've been working on improving the user experience for chat-based editing, adding more capabilities into our agent, and improving our agent infrastructure to continue to scale as models get better and better. The Agent team is a mix of AI Researchers and Software Engineers committed to our mission to make video editing accessible to anyone. Your peers will be based in San Francisco, New York, and distributed across the US and Canada.

This is the role for you if any of the following areas sound exciting:

• Experimentation to push the limits on quality for our video editing agent (eg. harness and tool design, token/context optimizations, RL/new model development, multimodal, etc)
• Building a best-in-class product experience for agentic video editing interactions and improving user retention (eg. tuning prompt templates and other key user workflows, addressing user feedback, building key product capabilities like chat history, etc)
• Laying the foundations for a best-in-class developer experience for building agents (eg. logging, evals framework, online monitoring and feedback loops, etc)

What you bring:

• Minimum Qualifications
  • 5+ years of professional product engineering or fullstack experience
  • Worked with Typescript, React, and RESTful APIs (or similar)
  • Solid CS fundamentals, including data structures, algorithms, databases (Postgres, Redis)
  • High ownership and growth mindset
  • You thrive in collaborative environments and enjoy working with other functions (e.g. product, design, AI research)

• Extra credit!
  • Experience building creative tools in the past or you're a frequent user of creative media tools. If you join Descript, you'll end up making lots of videos!
  • Experience building agents, working evals infrastructure, or designing product experiences powered by LLMs
