We’re looking for a Senior Backend Engineer to join the Messaging team.

The Messaging team owns Miro’s notification platform, ensuring users receive relevant, timely, and trustworthy notifications that help them stay informed and improve their Miro experience. This includes email notifications, in-app notifications, and the underlying systems that power them.

Our mission sits at the intersection of product experience and platform reliability. We enable Miro teams to communicate with users at the right moment, across channels, at scale – while avoiding noise, duplication, and overload. By building robust, scalable, and observable messaging system, we help Miro teams drive retention, engagement and clarity for millions of users.

We’re looking for a Backend Engineer who will help us evolve and scale Miro’s messaging and notification capabilities.

You’ll work on high-throughput, event-driven systems that operate under strict reliability, latency, and correctness requirements. The role requires strong software engineering fundamentals, experience with distributed systems, and a product mindset – understanding that every notification affects user trust.

You’ll take ownership of critical services, collaborate closely with Product and Platform teams, and help define stable, extensible interfaces that enable Miro teams to deliver meaningful user notifications safely and efficiently.

• Design and implement scalable, fault‑tolerant backend services for email and in‑app notifications
• Build and evolve event‑driven, asynchronous pipelines that process high volumes of product and user events
• Create high‑quality technical designs and write clean, maintainable, self‑documented production code
• Ensure correctness, idempotency, deduplication, and delivery guarantees across notification flows
• Optimize performance, latency, and scalability while maintaining reliability under peak load
• Take long‑term ownership of features and subsystems, including production health and evolution
• Collaborate with Product and Platform teams to deliver relevant and timely user notifications

• 6+ years of backend development experience (Java 17, Kotlin, Spring / Spring Boot)
• At least 4+ years of experience building and operating distributed systems in production environments
• Strong understanding of event‑driven architectures, async processing, and message‑based systems
• Solid knowledge of high‑load SaaS architecture, scalability, and reliability patterns
• Some experience with streaming/messaging platforms, notifications or feed‑like systems (email, in‑app, push, or similar)
• Familiarity with cloud infrastructure, preferably AWS, and production observability practices

We embrace AI‑first development. Our ideal candidate has moved way beyond basic Copilot usage, and integrated AI agents into their entire SDLC—from autonomous debugging and log analysis to rapid prototyping and shipping features to production. We expect you to be an expert "pilot" who can orchestrate AI tools to deliver high‑quality code at a pace that traditional workflows can't match. Practically this means that you are running multi‑agent flows using tools like Claude Code, Cursor or similar. If you’ve optimized your workflow to be 10x faster using the latest AI tools, we want to talk to you.
