Fullstack Developer

Deskripsi pekerjaan Fullstack Developer 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.
