Hostaway is seeking a highly motivated Senior Backend Engineer to join the Core team. This team is responsible for the integrations with our key partners (Online Travel Agencies). These integrations are critical to our customers’ daily workflows, powering seamless connectivity between their properties and major booking platforms. If you’ve worked on similar tools that handle huge volumes and interact with a variety of complex APIs, you’ll be a great fit!
Design, build, and operate backend services in PHP and Go
Drive the extraction of services out of our monolith, defining clean boundaries, ownership, and migration paths
Collaborate closely with the Product Manager to shape the technical direction and ensure our backend services deliver maximum value
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
6+ years of experience as a Backend Engineer, with a strong foundation in software engineering
Strong-level proficiency in PHP and/or Golang, with a strong willingness to dive into both
Proven experience designing and operating high-traffic, customer-facing systems
Experience decomposing monoliths or extracting services, with a pragmatic view on when to do it (and when not to)
Solid experience designing APIs — REST, GraphQL, or similar — with an eye on clarity, versioning, and consumability (bonus if you've built APIs for AI agents or LLM-driven clients)
Familiarity with transitioning event-driven service-oriented architectures by applying Domain Driven Design (DDD) principles
Comfortable using AI coding tools (Claude Code, Cursor, Copilot, etc.) as part of your daily workflow, and able to get real leverage out of them
Experience working in a Cloud environment (AWS is a plus)
Experience with message queues (e.g., AWS SQS) is a plus
