REQUIREMENTS

Must-have

Go backend microservices - Production experience; able to read and extend existing services quickly (hexagonal / clean architecture, gRPC and REST).

• Query & database optimisation - PostgreSQL and MongoDB. Indexing, query / explain-plan analysis, N+1 elimination, batching.
• Redis caching - TTL strategy, dedup, cache patterns on hot / high-traffic endpoints.
• Fullstack delivery - Proficient in a TypeScript / React (React Native or React web) frontend.
• Third-party integration - Payment and/or delivery-aggregator services. Async, polling, retry and idempotency patterns.
• Senior autonomy - Self-directed in complex domains with minimal onboarding. Disciplined Git workflow and code review.
• Nice-to-have
• AI-assisted development - Hands-on with Claude Code or similar agentic coding tools in a real workflow.
• F&B / QSR / POS domain experience.
• Delivery-aggregator integration experience.
• Offline-first / edge patterns: outbox, store-and-forward, conflict resolution, SQLite / embedded stores.
• Event-driven systems with RabbitMQ or similar message brokers.
• MongoDB, OpenTelemetry observability, Kubernetes, React Native + Expo.

AI-assisted development is a core part of how this team works. Candidates need not be experts, but must be comfortable and productive pairing with an AI coding agent day-to-day — prompting effectively and reviewing AI-generated changes critically.

TECHNOLOGY STACK

• Layer - Technology
• Language & runtime
• Go (backend services); TypeScript (frontend)
• Backend : GoFiber (fasthttp); REST and gRPC / Protobuf for internal service-to-service
• Databases : PostgreSQL; MongoDB; SQLite (embedded, offline POS)
• Caching : Redis — hot lookups, reservation locks, dedup
• Messaging : RabbitMQ — event-driven processing, outbox pattern
• Frontend / POS : React Native + Expo; react-native-web to Electron desktop POS; TanStack Query; Zustand; shared component library
• Observability : OpenTelemetry; Prometheus; continuous profiling
• Testing : Go unit tests with mocks and containerised integration tests; Playwright (web E2E); Jest
• Platform & CI/CD : Docker; Kubernetes; GitLab CI; database migrations; ULID for offline IDs

WAYS OF WORKING

• Two-week sprints; PRD-ready work items are a prerequisite so senior capacity is used on delivery rather than discovery.
• AI-assisted development with Claude Code
• Issue and sprint tracking (YouTrack); Git-based workflow with mandatory code review.
• Microsoft 365 for email, documents, and collaboration.
