# Software Engineer, Pub/Sub at Ably (UK)

You'll own core backend systems powering Ably's real-time messaging platform, tackling distributed systems challenges at planet scale. The role involves shipping new features, performance improvements, and maintenance across Ably's Pub/Sub APIs, LiveObjects state synchronization, and AI Transport messaging layer. You'll work hands-on with a talented engineering team, leveraging AI tools for planning and prototyping while maintaining full ownership of architectural quality and correctness—fast iteration with no shortcuts on substance.

This position suits engineers with strong distributed systems knowledge and experience building or operating messaging systems, streaming platforms, or pub/sub infrastructure at scale. You should be comfortable with Node.js or Go, capable of working independently through ambiguity, and have a pragmatic approach to AI tooling that balances speed with technical rigor. A collaborative mindset and interest in developer-first products are valuable, as is experience in early-stage, dynamic environments.

Based in London with full remote flexibility, this is a hands-on engineering role where you'll see your work directly impact millions of devices and major companies including Harness, EA, and HubSpot.
