Team description

Join the PandaDoc Editor Team

Ready to take ownership of the most challenging and critical part of PandaDoc? Collaborate closely with a talented team of 4 engineers to build a fast and reliable Editor with 99.99% uptime, terabytes of user data, thousands of concurrent editor sessions, and hundreds of thousands documents created daily. Join our international team and contribute to a strong culture of ownership and technical quality!

In this role, you will:

Product Ownership (40%):

• Take full ownership of the domain from a product perspective — deeply understand its features, functionality, and how it is used by clients.
• Implement new features and support other teams contributing to the Editor domain, providing guidance on efficient solutions, reviewing architectural designs, and ensuring high-quality code reviews.
• Continuously monitor domain quality by analyzing new bugs and user feedback.
• Collaborate effectively with other teams, product managers, engineering managers, and the support team to ensure fast and high-quality delivery.
• Actively participate in quarterly and sprint planning, retrospectives, and demos, providing both high- and low-level estimations.

Technical Ownership (60%):

• Maintain 99.99% uptime (we have 24/7 on-call duty, though incidents in our domain occur less than once a month).
• Consult on and review technical solutions, ensuring high-quality code and architectural integrity.
• Continuously analyze the current technical state of services, databases, and infrastructure, proactively improving stability and scalability to support user growth.
• Monitor and optimize performance, ensuring the domain remains fast and efficient.
• Share knowledge by writing documentation, conducting tech talks, and leading workshops to foster team and company growth.

Our stack:

• Service-oriented architecture, the main service working with content uses the event sourcing approach
• Editor-related Python services are primarily written using AsyncIO frameworks and libraries, but we also have in ownership some Django-based services
• We aim to use the latest versions of every dependency
• AWS and K8S are used extensively for provisioning and deploying workloads
• The main cross-service communication transports:
• NATS is our main RPC transport, but we’re migrating to gRPC to eliminate the single point of failure with NATS
• Kafka and Debezium for event-based operations
• RabbitMQ is a transport for Celery, but we look forward to migrating to Temporal.io
• Temporal.io as a new promising solution
• Websocket for communication with frontend
• Storage:
• PostgreSQL, Redis, S3
• LGTM stack for monitoring

About you:

Must have:

• At least 4+ years of development experience with Python
• English: Upper-intermediate+ (verbal and written)
• Care about quality; you know what shipping high-quality code means
• Strong understanding and experience in AsyncIO
• Experience with any relational databases (SQL queries, migrations, optimization)
• Experience with message queues (e.g., RabbitMQ, Kafka)
• Experience with Amazon Web Services and Kubernetes
• Hands-on experience in developing a service-oriented architecture
• Hands-on experience with CI/CD (e.g., GitLab)

Nice to have:

• It is good to have experience with the LGTM stack and OpenTelemetry
• It is good to have open-source contributions and experience
• It is good to have experience with event sourcing approach
