# Backend Engineer (Senior) - Forecasting and Replenishment

> Makro PRO · Bangkok, Thailand (Hybrid) · Full-time · Posted 2025-10-15

**Workplace:** hybrid

**Department:** Technology

## Description

We are looking for a Senior Backend Engineer to build and operate services that power **Forecasting and Replenishment (FNR) systems at CP Axtra (Makro).** This role is for someone who can **design clean APIs and business logic**, and who is also comfortable **owning parts of the operational stack** when needed. You will work across **backend services, data flows, integrations, and reliability practices** to deliver systems that are stable, observable, and easy to evolve.

**Key Responsibilities**  

-   **Design, build, and maintain backend services** using **Java and Spring Boot** for FNR applications and workflows.
-   Own end-to-end delivery of features: requirements clarification, **technical design, implementation**, testing, release, and operational support.
-   **Build robust APIs** for data-heavy use cases including search, filtering, pagination, and bulk-like workflows where appropriate.
-   Implement and maintain asynchronous processing **using Kafka** (event-driven flows, consumers, retries, idempotency, and reprocessing patterns).
-   Design and optimize **Postgres schemas, queries, and indexes** for performance and correctness at scale.
-   **Use Redis for caching**, distributed locks, and performance improvements where appropriate.
-   Implement **security and access control patterns** suitable for internal enterprise systems (authentication integration, role-based access).
-   Improve observability and reliability: **structured logging, metrics, tracing, dashboards, alerts, and incident debugging.**
-   Collaborate with Frontend Engineers, Data Engineers, Data Scientists, and business stakeholders to deliver end-to-end workflows.
-   Contribute to **platform and infrastructure work when needed** (CI/CD improvements, environment setup, service configuration, production readiness checks).

## Requirements

-   **5+ years** strong experience building production **backend systems with Java and Spring Boot.**
-   Strong **SQL skills** and experience designing and **optimizing Postgres**\-backed applications.
-   Hands-on experience with **Kafka or similar messaging systems**, including consumer design, error handling, and operational patterns.
-   Experience **using Redis in backend systems** (caching strategies, TTLs, invalidation, and concurrency control).
-   Good understanding of distributed system fundamentals: **consistency trade-offs, retries, idempotency, backpressure, and failure modes.**
-   Strong engineering practices: **code reviews, automated testing, documentation, and disciplined release management**.
-   Operational mindset: **ability to debug issues in production** using logs/metrics/traces and drive fixes through to resolution.
-   **Clear communication and ownership mindset**, able to work with cross-functional stakeholders.

### Nice to Have

-   Experience with **infrastructure and operations work**: containers, **Kubernetes, service deployment, or cloud environments (Azure/AWS/GCP).**
-   Experience with **CI/CD pipelines** and r**elease automation (GitLab CI, Jenkins, GitHub Actions, or similar).**
-   Experience with o**bservability tooling (OpenTelemetry, Prometheus/Grafana, ELK, Datadog, or similar)**.
-   Familiarity with **schema migration tooling** and practices (Liquibase/Flyway).
-   Experience **building internal platforms or shared libraries** for consistent integration patterns.
-   Experience in **retail, supply chain, forecasting, replenishment, or operations-heavy domains.**

### What Success Looks Like

-   Core FNR services are reliable, observable, and easy to evolve as business rules change.
-   APIs and data flows are consistent and predictable, with clear error handling and stable contracts for consumers.
-   Kafka-based processes are safe to operate with retry, reprocessing, and idempotency patterns in place.
-   Performance remains strong as data volumes grow through efficient Postgres design and caching strategies.
-   The team ships frequently with low regressions, and production issues are detected and resolved quickly.

### Tech Environment (Indicative)

-   Java, Spring Boot
-   PostgreSQL
-   Kafka
-   Redis
-   Standard tooling for CI/CD, monitoring, logging, and tracing in an enterprise environment
