We are engaging Senior Fullstack Engineers on a three-month contract to accelerate delivery of an enterprise-grade Quick Service Restaurant (QSR) platform — spanning point-of-sale (POS) and backoffice operations, including ERP-level capabilities.

  • This is a senior-only engagement. We are looking for engineers who can:
  • Work full-stack across Go backend microservices and a cross-platform POS client.
  • Become productive in a live, complex codebase with minimal onboarding.
  • Operate independently across demanding domains such as order, payment, integration, and inventory.

Ideal candidates bring hands-on context in high-throughput transactional systems, third-party and payment integration, performance optimisation, and offline-first POS.

KEY RESPONSIBILITIES

  • Design, build, and extend features end-to-end across backend services and frontend clients.
  • Implement transactional flows (ordering, payment, fulfilment) with reliability patterns — async processing, retries, and idempotency.
  • Build offline-first capability for POS: local-first data, store-and-forward sync, and conflict handling.
  • Integrate third-party and payment services.
  • Improve system performance: query optimisation, caching, and endpoint hardening.
  • Contribute to master data, inventory, and reporting capabilities.
  • Collaborate through code review and sprint-based delivery.

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 and is eDOT's standard. 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.
