Job description for Fullstack Developer at Skyshi Digital Indonesia
ROLE SUMMARY
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; and
- 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 deliveryaggregator services; async, polling, retry and idempotency patterns.
- Senior autonomy — self-directed in complex domains with minimal onboarding; disciplined Git workflow and code review
Note :
- This opportunity for full remote
