Senior Python Engineer – AI Agents

PandaDoc is on a mission to build the future of documents.

We provide an all-in-one document workflow automation platform that helps fast-scaling teams accelerate the ability to create, manage, and sign digital documents including proposals, quotes, contracts, and more. We empower more than 75,000 growing organizations to thrive by taking the work out of document workflow. 

We're a fast-growing company with a global reach. Our product is used by people around the world, from small businesses to large enterprises. In 2024, we reached a major milestone: over $100 million in annual recurring revenue! We're constantly innovating and releasing new features to meet the evolving needs of our customers, while also staying focused on stability, quality, and performance.

Our Engineering team is a diverse and talented group of about 200 individuals who are passionate about building a world-class product. While this is a fully remote position, we'd love for you to visit our vibrant offices in Warsaw, Lisbon, or Kyiv whenever you'd like to connect with colleagues in person.

The Team

We're forming multiple AI Agent teams across three strategic tracks: Growth, Customer Value, and App Platform to build the future of AI-powered agreements creation and management at PandaDoc.

The teams’ mission is to enable users to create and manage business documents—like contracts, quotes, and proposals—quickly and intelligently with the help of large language models and our internal AI platform.

As a Back-End Engineer on this team, you’ll play a key role in designing and building the systems that power these new experiences. That includes integrating with our AI platform, orchestrating multi-step generation workflows, ensuring scalability and reliability, and working closely with front-end and ML engineers to deliver fast, smooth, and secure user flows.

This is a rare chance to work on greenfield initiatives with real product impact and deep technical challenges—from building APIs for smart content generation and management  to evolving our models to support AI-first use cases. If you're excited about creating something from scratch and pushing the limits of intelligent automation, we’d love to talk.
