Kỹ Sư Tự Động Hóa & Hệ Thống Trí Tuệ Nhân Tạo | Senior Automation & AI System Engineer

Zeder Corporation is hiring two Senior Automation & AI System Engineer into our Automation and AI team in Hanoi. These are senior hands on engineering roles. You will take a business problem, scope it properly with the people who own the process, and then build and ship the solution yourself. The work covers three areas and you will move between all of them: conventional automation and system integration, agentic automation, and LLM assisted automation. A large part of the job is knowing which of the three a given problem actually calls for.
SCOPE OF WORK
Scoping and requirements
- Meet with department stakeholders to understand the process, the problem and the outcome they actually need.
- Map current state processes and identify where automation delivers real value rather than automating waste.
- Write clear scoping documents covering requirements, proposed approach, systems and data involved, effort estimate and success measures.
- Recommend the right approach for each project, whether that is a platform workflow, an agentic system, an LLM assisted step or a code solution.
- Push back on requests where automation is not the right answer, and say so with reasoning.
Engineering and Delivery
- Build, test and deploy automations end to end, from approved scope through to production and handover.
- Design integrations across our systems using REST APIs, webhooks and file based transfers, including authentication, rate limiting, pagination, retries and data mapping.
- Write production JavaScript and Python for logic that a platform cannot handle properly.
- Build systems that survive contact with reality: idempotent operations, sensible retry and backoff, queueing, dead letter handling, and failure states that alert someone rather than failing silently.
- Model and manage the data behind multi step processes, including state, queues and reconciliation.
- Work with our existing stack, which includes NetSuite, Microsoft Dynamics Navision, Magento 2, Freshsales, Freshdesk, Stripe, Google BigQuery, Twilio and Asana.
Tooling Philosophy
We use n8n as our primary automation platform and we want to keep it that way. Platform based workflows are visible, supportable and maintainable by more than one person, which matters far more over a five year horizon than elegance does. Your default should be to build on the platform where the platform can genuinely do the job.
You drop to code when the platform is the wrong tool, not when code is the more interesting option. When you do write code, it is production code: version controlled, documented, tested and deployable by someone other than you.
AI and Agentic Systems
- Build agentic workflows that combine planning, tool use and decision making using LLMs.
- Integrate LLMs into business processes for classification, extraction, summarisation, document routing, drafting and decision support.
- Treat prompts as production assets: versioned, tested, and managed with attention to context, structured outputs and tool definitions.
- Manage agent memory and state across multi step actions, and design guardrails, validation and human review points where the cost of an error is high.
- Evaluate output quality with a defined method rather than by impression, and monitor it after launch.
- Control token cost and latency as first class design constraints.
- Recognise when an LLM is the wrong tool and use ordinary code instead.
Reliability, Documentation and Support
- Own the reliability of what you build, including monitoring, logging, alerting and error handling.
- Maintain technical documentation and runbooks in Confluence so automations can be supported by others.
- Track work in Jira and Asana and keep status current without being chased.
- Apply sound security practice around credentials, API keys, permissions and the handling of customer and commercial data.
- Support and improve automations already in production, not only new builds.
In addition to the duties listed above, the position holder must carry out tasks assigned by the supervisor that are essentially related to duties.
