Senior Backend Engineer, Guest Portal - 100% Remote - EMEA

About the role

We're looking for an impact-focused Senior Backend Engineer to join our Booking Platform team, this team that owns Hostaway's guest-facing services: the guest portal and the direct sales site builder. These products are how our customers' guests discover, book, and interact with their stays — they're public-facing, high-traffic, and directly tied to our customers' revenue.

You'll work on services that need to be fast, reliable, and scalable. A big part of our current focus is extracting existing services out of the monolith to give us the autonomy, performance, and resilience these guest-facing flows require. In parallel, we're starting to expose our domain through APIs designed for agentic interfaces — opening up new ways for guests and partners to interact with Hostaway. You'll have a real impact on the architecture, the roadmap, and how the team operates.

What you'll do

• Design, build, and operate backend services in PHP and Go that power the guest portal and direct sales site builder.
• Drive the extraction of services out of our monolith, defining clean boundaries, ownership, and migration paths.
• Collaborate closely with Product and Design to shape and ship features that move the needle for direct bookings.
• Design and ship APIs built for agentic interfaces — making our guest-facing domain consumable by AI agents and automated workflows.
• Improve page speed and end-to-end performance, working closely with frontend peers since conversion depends on it.
• Contribute to high-level architectural decisions and help us move quickly without accumulating regret.
• Leverage AI to accelerate code delivery — we provide a Claude Team Premium subscription and expect engineers to use it well.
