Fullstack Engineer (eprocurement)
CL160-R022 · Tech
WFH, 12 months contract
Tech Company
Role Detail
Key Responsibilities:
Backend Development & APIs
- Design, develop, and maintain Go backend microservices exposing REST and gRPC / Protobuf APIs, following clean / layered architecture.
- Model, query, and optimise data in MongoDB (schema design, indexing, aggregation pipelines, pagination), with Redis for caching.
- Implement procurement business flows — approvals, state transitions, document versioning, and event history — with correctness, auditability, and multi-company data isolation in mind.
- Build asynchronous, event-driven processing with RabbitMQ (e.g. export/import jobs, notifications, scheduled reports), applying retry and idempotency patterns.
- Build and extend procurement modules in a TypeScript / React micro-frontend monorepo (Next.js, pnpm, Turborepo) using a shared internal design system.
- Implement data-heavy enterprise UI: complex forms and validation, configurable tables and views, advanced filters, attachments, and multi-language support.
- Manage server and client state (e.g. TanStack Query, Zustand) against backend APIs; optimise for performance and usability.
- Collaborate with product and design to translate requirements and UI/UX into high-quality, accessible implementations.
Integration & Platform
- Integrate with other eSuite microservices (master data, inventory, finance & accounting, notification, reporting) over gRPC and message queues.
- Contribute to ERP integration flows (e.g. SAP) for vendors, purchase orders, and goods receipt — including outbound push, status synchronisation, and error handling.
- Contribute to file export/import, document generation, and object-storage based attachment handling.
Project Delivery & Collaboration
- Own end-to-end delivery of features across backend and frontend: refinement, estimation, implementation, testing, and production release — each item shipped to production within its own delivery cycle.
- Work from PRDs and RFCs; write or contribute to technical design documents for your features.
- Coordinate with product, QA, and DevOps to meet release timelines; take part in production support and bug fixing when needed.
- Code Quality, Testing & Knowledge Sharing
- Write and maintain unit, integration, and end-to-end tests (e.g. Go testing with testcontainers, Vitest, Playwright).
- Participate in merge-request reviews and uphold coding standards, security baselines, and documentation practices.
- Actively share knowledge and help keep the team’s technical knowledge base current.
Qualifications & Requirements:
Education & Experience
- Bachelor’s degree in Computer Science, Information Technology, or a related field.
- Minimum 5 years of experience in fullstack software engineering (backend + web frontend), with a proven track record of shipping production applications.
- Demonstrated ability to become productive quickly in a large, live, multi-service codebase with minimal onboarding.
Domain Experience (Procurement / ERP)
- Required — Hands-on experience building enterprise business applications: ERP, eprocurement, supply chain, finance, or other back-office / B2B SaaS systems.
- Familiarity with procure-to-pay concepts — purchase requisition, purchase order, goods receipt, vendor management, contracts, approval workflows, budgets, and tax / currency handling.
Technical Skills (eprocurement stack)
- Backend — Strong hands-on Go (Golang) for production microservices (e.g. Fiber or similar HTTP frameworks); comfortable reading and extending existing services quickly.
- Databases — Solid experience with MongoDB (schema design, indexing, aggregation); Redis for caching.
- Frontend — Proficient with TypeScript, React, and Next.js; experience with form, state, and datafetching libraries (React Hook Form or TanStack Form, Zod, TanStack Query / Table, Zustand) and Tailwind CSS.
- API design — Solid understanding of RESTful and gRPC / Protobuf API design and inter-service contracts.
- Messaging — Experience with RabbitMQ or similar brokers for asynchronous, event-driven processing.
- Version control — Proficient with Git and GitLab-style collaborative workflows (branching, mergerequest reviews, CI pipelines).
- Fundamentals — Solid grasp of data structures, testing, debugging, and performance optimisation.
- AI-assisted development — Proficient using AI coding assistants (e.g. Claude Code, GitHub Copilot, Cursor) to accelerate development, review, debugging, and documentation — while maintaining code quality, security, and sound engineering judgment.
Soft Skills
- Strong analytical and problem-solving skills; able to turn business requirements into clear technical solutions.
- Good communication in Bahasa Indonesia and English, and ability to work cross-functionally.
- Ownership mindset, proactive, and able to work independently with minimal supervision.
- Comfortable in a fast-paced, delivery-focused project environment with clear async communication.
Nice to Have
- ERP integration experience, particularly SAP (e.g. IDoc, BAPI, OData, or middleware-based integration).
- Experience with micro-frontend architecture and monorepo tooling (pnpm workspaces, Turborepo).
- Experience building configurable / metadata-driven features: custom fields and objects, rule engines, workflow or process automation, notification templates.
- Reporting and data-export experience (scheduled reports, large export/import jobs).
- Observability and cloud-native tooling: OpenTelemetry, Docker, Kubernetes, GitOps (e.g. ArgoCD).
- Experience with multi-company / multi-tenant SaaS and role-based permission models.
