Mid-level Engineer

About the Position

We are looking for a Mid-level Engineer to join our Collaboration Runtime team at Miro. You will play a crucial role in building a decoupled Collaboration Engine designed to enable "ubiquitous collaboration" across the entire company. This role is pivotal as we transition from a board-centric monolith to a scalable, high-performance platform that supports real-time interaction for millions of users.

About the Team

The Collaboration Runtime team is part of the Runtime Platforms domain. We are building a lightweight, reusable Collaboration Engine designed to decouple real-time collaboration from the monolith. Our mission is to democratize stateful app development, enabling "ubiquitous collaboration" across new surfaces like AI History, Dashboards, and Spaces. We own the core WebSocket transport, gRPC Server Proxies, and the Broadcast Application infrastructure.

Responsibilities

• Implement core features of the Collaboration Engine and the Broadcast Application to ensure the AI History use case is production-ready by the end of Q1
• Develop and optimize gRPC streaming support (unary, bidi, and server-side) within the collaboration proxy to enable complex real-time data flows
• Build out the Application & Server Registry, enabling discovery and routing for new services like the CIS "live updates" dashboard
• Execute the rollout of connection multiplexing between the RTC Gateway and application servers to improve system efficiency and scale
• Write high-concurrency code in Java/Kotlin to manage WebSocket transport paths and ensure low-latency real-time client connectivity
• Partner with AI and Platform teams to integrate their services with the Engine, ensuring high reliability and 99.9% uptime

Requirements

• Strong proficiency in Java or Kotlin, with a solid grasp of multithreading and JVM performance
• Practical experience building and maintaining high-load distributed systems or microservices
• Hands-on experience working with WebSockets and gRPC for real-time data transport
• Familiarity with concurrency patterns and the ability to debug complex, stateful application issues
• Ability to translate technical requirements into clean, testable code that integrates with complex backend proxies
• Effective communication skills to collaborate with partner teams on API definitions and service integrations

We want you to feel supported, connected, and ready to grow. Our global benefits package generally includes equity, a wellbeing benefit, a WFH equipment allowance, and an annual Learning & Development stipend. Join a diverse team where you can do your best work. Full benefits may differ per location.
