Senior Backend Engineer

Who you are

• 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

What the job involves

• 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
• What success looks like:
• Services are progressively extracted from the monolith with clear ownership and minimal disruption to delivery
• Performance (page speed, latency, uptime) becomes a measurable strength of the products
• Our domain is accessible through clean, well-designed APIs that agentic clients can consume reliably
• The team gets real productivity gains from AI-assisted development, without sacrificing code quality or ownership
• Cross-functional collaboration with Product and Design runs smoothly, with engineering contributing meaningfully to product direction
