Job Description:
Responsibilities
- Lead the design and implementation of the new platform architecture — from legacy systems to modern stacks
- Build and integrate AI-powered features into the core product
- Collaborate directly with leadership on architecture decisions, technical priorities, and product roadmap
- Set code standards, review practices, and engineering culture on a small team
- Own integrations with external APIs and third-party systems
- Maintain business continuity during migration phases — zero downtime wherever possible

Must-Haves
- Full-stack proficiency: strong backend (Node.js, Python, or equivalent) AND frontend (React or Vue) — required
- Demonstrable experience replatforming or migrating legacy systems to modern architectures
- AI-first workflow: regular use of AI coding tools (Copilot, Cursor, Claude, etc.) in day-to-day development
- REST API design, relational database design, and SQL
- Git, CI/CD pipelines, and cloud environments (AWS or Azure)
- Ability to operate with genuine ownership in a lean, low-process team

Nice to Have




- Experience with the hospitality industry or B2B SaaS products
- Microservices or event-driven architecture experience
- Familiarity with observability tooling: Datadog, Sentry, or equivalent
- Hands-on experience with LLM APIs (OpenAI, Anthropic, etc.) or AI agents in production
- Technical English sufficient for documentation and corporate team communication

Who This Is NOT For
- Junior or early-career developers — this role requires genuine mid-senior depth
- Specialists: pure frontend engineers, pure backend engineers, or pure data engineers
- Candidates who haven't shipped production code recently or who rely on heavy team scaffolding
- Anyone who views AI coding tools as a threat rather than a multiplier
