The Opportunity
We're looking for a Senior Backend Engineer to help us reinvent Postman's Notifications Platform for the next generation of AI-powered, agent-driven experiences.
As Postman evolves to support agents and autonomous workflows, notifications become much more than simple alerts. They need to be contextual, intelligent, reliable, and deeply integrated into how users interact with the platform. You'll play a key role in building the foundation that makes that possible.
This isn't a role focused on maintaining an existing system. It's an opportunity to rethink and rebuild a critical platform from the ground up that will power notification experiences across Postman for years to come.
You'll have significant influence over the platform's architecture, reliability, and developer experience, working closely with teams across the company to build something scalable, intuitive, and easy to adopt.
What You'll Do
As a Senior Backend Engineer on the Messaging team, you'll help design and build the next generation of our Notifications Platform.
Some of the things you'll work on include:
• Reimagining the platform to support agentic, event-driven notification workflows.
• Designing backend systems that enable contextual notifications triggered by agents, workflows, and product events.
• Building reliable platform primitives for triggering, routing, delivery, retries, deduplication, rate limiting, user preferences, and notification lifecycle management.
• Partnering closely with teams building Agents and AI-powered experiences to understand their needs and translate them into scalable platform capabilities.
• Improving the developer experience through well-designed APIs, self-serve tooling, documentation, and integration workflows.
• Expanding observability across the entire notification lifecycle—understanding what triggered a notification, why it was sent, how it was delivered, and whether it succeeded.
• Ensuring the platform is designed with reliability and user trust at its core, minimising issues such as duplicate sends, stale notifications, noisy experiences, and incorrect targeting.
•
