Principal AI Engineer ( AI agent, RAG, Vector DB)

Senior Forward-Deployed Engineer (FDE)/ Principal AI Engineer

Location: Lim Tower 3, Nguyen Dinh Chieu, District 1, Ho Chi Minh city

Type: Full time office

Engineering Focus: AI Cognitive Ontologies, Agentic Applications, Customer Solutions

About the Role:

We are hiring a Senior Forward-Deployed Engineer (FDE)/ Principal AI Engineer to work directly with customers to design, build, and deploy production-grade agentic applications powered by cognitive ontologies and domain-aware reasoning systems. You will be customer-facing but not

embedded supporting multiple accounts through high-impact technical engagements,

architecture design, and implementation of critical solution components.

Responsibilities:

● Lead technical discovery and translate customer workflows into cognitive ontologies, agent logic, and solution architectures.

● Build production-ready components: pipelines, integrations, APIs, domain adapters, reasoning modules.

● Guide customers through deploying, validating, and refining agentic applications using our platform.

● Collaborate closely with product engineering to surface platform gaps and drive improvements.

● Develop reusable patterns, templates, and deployment best practices that scale across customers.

● Provide expert technical guidance during workshops, design sessions, and milestone checkpoints.

Requirements:

● 7 years of hands-on software engineering experience, ideally in customer-facing or

solutions engineering roles including at least 3 years working with AI/LLMs in a production environment.

● Strong software engineering background (Python or TypeScript preferred).

● Experience with distributed systems, data pipelines, APIs, and system integration.

● Proven experience building complex AI applications using LLMs, with hands-on experience in AI

Agents, Agent Frameworks, or Agentic Workflows and deploy AI agent in the system.

● Solid understanding of modern AI architectures: RAG, AI Agents, orchestration workflows, and tool integration

- Experience with LLM providers and APIs such as OpenAI, Anthropic, Azure OpenAI, or open-source models.

- Familiarity with agent orchestration concepts such as multi-step reasoning flows, tool use, memory, multiple LLM calls, and multi-agent workflows.

● Ability to communicate clearly with customer engineering and domain teams.

● Comfortable working across multiple customer accounts with structured engagement cyc

● Fluent English communication.

Who You Are:

● A builder who enjoys solving real customer problems with real engineering.

● Equally strong at technical deep dives and customer-facing collaboration.

● Thrives in ambiguity and can convert domain complexity into clean technical solutions.

Before You Apply:

We move fast and we expect a lot. This role probably isn't right for you if:

● You find ambiguity stressful rather than something to resolve

● You prefer to stay in your lane rather than flag problems outside your immediate scope

● You're looking for an engineering role inside a mature structure with a full support team

around you

But if you're the kind of engineer who sees a broken integration and can't help but fix it — who

treats we've never built that before as an invitation rather than a blocker — this is the role you've

been looking for.

Why you'll love working here:

● Attractive compensation and benefits commensurate with impact.

● Daily lunch allowance

● Overseas travel opportunities for training and work, providing exposure to international

projects and collaborations.

● An employee-centric culture that values skills and abilities, providing the necessary tools

and resources to excel and advance in careers.

● A collaborative work environment that fosters teamwork, knowledge sharing, and

innovation.

● Flexible working hours.
