Kerja Sepenuh Masa, AI Engineer di Optimum Solutions Pte Ltd - Maukerja

Key Responsibilities:

We are looking for a GenAI Application Engineer who operates effectively at the intersection of software engineering, GenAI application development, enterprise integration and production delivery.

This is not a pure research role. It is not a prompt engineering only role. The successful candidate will help design, build and improve production grade GenAI applications that are reliable, observable, maintainable and useful to real enterprise users.

The successful candidate will:

1. Build and improve GenAI applications using frameworks such as LangGraph, LangChain or similar orchestration tools.
2. Work with open weight models, hosted LLMs and model serving patterns.
3. Develop agentic workflows, retrieval augmented generation, tool calling and prompt orchestration.
4. Integrate GenAI applications with enterprise systems, APIs, data sources and operational platforms.
5. Engineer solutions for production quality, including logging, tracing, evaluation, fallback behaviour and troubleshooting.
6. Bring a strong can do attitude, enthusiasm, curiosity and practical delivery mindset.

What Matters Most

1. Strong hands on experience building production grade GenAI applications.
2. Practical experience with LangGraph, LangChain, agentic workflows, RAG and tool calling.
3. Understanding of open weight models and how to integrate them into real applications.
4. Ability to challenge weak designs and propose better ones.
5. Strong engineering discipline around reliability, testing, observability and maintainability.
6. Ability to work across application, data, platform, security and infrastructure teams.
7. Enthusiastic, energetic and willing to get into the details.
8. Pragmatic approach to delivery, not over engineering, not hype driven.
