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
