Qualifications

• 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.

Responsibilities

• 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.
