About LINE MAN Wongnai

LINE MAN Wongnai is Thailand’s Leading On-Demand Delivery and Lifestyle e-Commerce platform services. We build technology to help Thai people live better, to empower all local businesses by creating an end-to-end food ecosystem through our channel LINE MAN and Wongnai. Connected consumers, riders, and local businesses and improved the daily life of all parties with restaurants nationwide. And because we are local, we provide the deepest variety and services that are tailor-made for Thai people.

This role sits in the team that owns our CRM Platform and AI Integration layer — the systems that power how customer-facing agents and AI bots support riders, users, and merchants every day, spanning the chat experience end users interact with, the backend services that route conversations, and the integrations that let AI handle real customer issues end-to-end. You’ll work at the intersection of real-time messaging, CRM customization, and applied AI — building infrastructure that directly impacts how millions of LMWN customers get help.


Please visit our engineering blog if you’d like to learn more.

What You’ll Do:

  • Build the AI Agent-Assist Platform: Own the platform, internal consoles, and back-office automation that support teams use every day — the systems that turn AI into real, measurable productivity.
  • Architect the AI Resolution Engine: Design reliable AI-driven pipelines that auto-draft, triage, route, and resolve issues end-to-end — with the production guardrails and evaluation to keep them trustworthy at scale.
  • Eliminate Operational Friction: Embed with support teams, find the highest-cost pain points, and ship the tools, automations, or process changes that remove them for good.
  • Unify the Support Stack: Orchestrate data and actions across CRM, ticketing, and internal services so work flows automatically — no manual copy-paste, no swivel-chair.
  • Engineer for Scale & Reliability: Build robust, event-driven services and APIs that stay rock-solid during live customer operations.
  • Raise the Engineering Bar: Set the standard for code quality, testing, observability, and end-to-end ownership across the team.

What You’ll Need: 

  • 3-5+ years of professional software engineering experience building and operating production systems at scale.
  • Strong backend engineering skills in Go or JAVA (Required). Experience with TypeScript / Node.js, or with Kotlin, C#, is a plus.
  • System Design: Proficiency in microservices, event-driven architecture, distributed systems, and API design (REST/gRPC).
  • Integration Skills: Hands-on experience with third-party APIs (versioning, auth, retries, degradation).
  • Database Fundamentals: Strong SQL (Postgres/MySQL) knowledge: schema design, query tuning, and consistency modeling.
  • Infrastructure: Proficiency in Docker, Kubernetes, CI/CD, and monitoring/observability tools.
  • Collaboration: Strong cross-functional communication and ownership mentality; able to translate business needs into technical specs.
  • Ownership mentality — end-to-end responsibility from design through production, including monitoring, alerting, on-call, and operational health.

It'd be Great if you have:

  • Experience with the Salesforce platform or other CRM platforms — e.g., Salesforce (Apex, Lightning Web Components, Service Cloud, Messaging, metadata / SFDX deployments, permission and profile management in source control), or comparable customization and integration experience on other enterprise CRM systems.
  • Experience integrating with or building on top of LLMs and AI agent frameworks — function/tool calling, streaming responses, prompt engineering, hallucination/safety guardrails, evaluation pipelines.
  • Experience building chatbot, conversational AI, or contact-center platforms — session state machines, copilot flows, agent-assist tooling, handoff orchestration.
