Backend Module Engineer

1 day ago

Bacolod City, Western Visayas, Philippines iReply Back Office Services Inc. Full time ₱1,200,000 - ₱2,000,000 per year

Overview

We are building a Management Portal Platform designed to support multiple operational modules (e.g., billing, job processing, provisioning, reporting). Each module is developed independently but plugs into a shared core framework that provides the API gateway, database conventions, job queue, and shared utilities.

We are seeking a Backend Module Engineer to design and implement feature modules on top of this platform. The first major focus will be the Billing module (usage collection, invoicing, payments), but this role will also extend to future modules such as Provisioning, Reporting, and Notifications.

This role involves owning modules end-to-end: defining GraphQL schema extensions, implementing resolvers, designing database tables, and building background jobs that integrate with external systems.

Responsibilities

Module Development

  • Design and implement GraphQL schema extensions for modules (types, queries, mutations).
  • Implement resolvers that connect GraphQL queries/mutations to business logic.
  • Define and manage module-specific database schemas (e.g., invoices, usage, devices).
  • Ensure module schemas follow core conventions (naming, migrations, ownership).

Background Jobs

  • Implement background jobs for module-specific tasks (e.g., CDR ingestion, invoice generation, provisioning updates).
  • Register jobs with the shared Redis + BullMQ queue using module-specific namespaces.
  • Ensure jobs update their status and progress in the database.
  • Handle retries, error logging, and failure recovery.

Integration

  • Collaborate with the Backend Platform Engineer to ensure modules follow core standards.
  • Use shared utilities (config, logger, error handler, types) from /packages/shared.
  • Expose module APIs through the GraphQL gateway.
  • Ensure modules can be developed independently but integrate seamlessly.

Scalability & Modularity

  • Design modules to be self-contained and microservice-ready.
  • Ensure modules can be split into independent services in the future if needed.

Document module APIs, schemas, and job types for other developers.

Requirements

  • Strong experience with + TypeScript.
  • Experience with GraphQL (schema design, resolvers, modular schemas).
  • Strong knowledge of PostgreSQL (schema design, queries, migrations).
  • Experience with Redis and background job processing (BullMQ, RabbitMQ, or similar).
  • Familiarity with Docker and containerized development workflows.
  • Ability to design modular, scalable backend services.
  • Strong communication skills for collaborating on API contracts and module boundaries.
  • Bonus: experience with billing systems, telecom APIs, or reporting/analytics platforms.

Job Types: Full-time, Permanent

Pay: Php50, Php80,000.00 per month

Benefits:

  • Company events
  • Health insurance
  • Work from home

Experience:

  • Backend: 5 years (Required)
  • + TypeScript: 3 years (Required)
  • GraphQL: 3 years (Preferred)

Work Location: In person
