About LIQAVO

LIQAVO unifies venue reservations, event tickets, transfers and hotel coupons in the Çeşme region into a single app. Our mission is to digitalise hospitality and make the experience seamless, fast and trustworthy for both businesses and guests.

LIQAVO is an independent studio building mobile applications, web platforms and brand content. As our engineering scales, we are hiring an experienced full-stack engineer to take real end-to-end ownership of features and the systems beneath them: data models, API contracts, authorisation logic and the performance characteristics of every layer. You will work directly with the founding team. Most architecture and database decisions are made in small rooms. This role suits an engineer ready to own work across cross-platform mobile clients and server-rendered web applications written in TypeScript. The environment is small but fast-moving; production traffic is real, the feedback loop is short.

Responsibilities

  • Lead the design, development and delivery of features across cross-platform mobile clients and TypeScript-based server-rendered web applications
  • Design PostgreSQL schemas, indexes, triggers and row-level security policies; monitor and tune query performance
  • Build server-side logic in TypeScript runtimes (Node or Deno-based serverless platforms)
  • Define and document REST API contracts; build idempotent, race-safe operations on critical paths
  • Establish component architectures, code standards and engineering practices; review PRs constructively
  • Diagnose production issues from logs and metrics; ship hot-fixes when needed
  • Mentor a junior engineer as the team grows

Requirements

  • 4+ years of professional full-stack engineering experience
  • Production experience with TypeScript and a modern React-based web framework
  • Hands-on PostgreSQL: schema design, query tuning, RLS or equivalent authorisation models
  • REST API design: pagination, error contracts, auth flows (JWT, OAuth)
  • Cross-platform mobile development experience (Flutter, React Native or native iOS/Android)
  • Worked with serverless or edge-based deployment models
  • Comfortable reading SQL execution plans and tuning queries
  • Experience with Git workflow, code review and CI/CD practices
  • Shipped 0-to-1 products; experience in small or fast-moving teams
  • Able to read technical documentation in English

Nice to have

  • Shipped a mobile application to the App Store and Google Play
  • Worked with object storage and signed-URL workflows for private media
  • Built HMAC-signed token verification, rate limiting or production abuse-prevention systems
  • Contributed to a design system through component architecture
  • Open source contributions
  • Shipped products under GDPR or similar data-protection regulations
