Senior AI Engineer - Vietnamese Fluency Required

Up to 4000$ - Vietnamese Fluency Required
Job description
About Huenx AS
Huenx AS is an AI-first consultancy and product company based in Norway. We deliver software and AI consulting services to clients across Norway and Europe, and we build our own AI-driven products. Our model brings together Norwegian business insight and senior Vietnamese engineering talent - small, highly skilled teams that work effectively with AI to deliver faster than larger organizations.
Our work spans production LLM systems - intelligent assistants, copilots, and agent-based workflows - and the data platforms that power them, across clients in multiple industries.
The role
This is a hands-on senior / lead AI engineering role. You design and ship production-grade AI systems, use AI tools as a core part of how you work, and work directly with our team and our international clients. As a technical lead, you set architecture and quality standards and guide other engineers.
Data engineering experience is a strong plus, not a requirement. Many of our AI systems sit on top of data pipelines and platforms, so the ability to work across that layer - or the willingness to grow into it - is valuable, but we're hiring first and foremost for AI depth and technical leadership.
Responsibilities
Design and implement production-grade LLM systems - retrieval, embeddings, semantic search, and agent or workflow-based pipelines.
Combine LLM reasoning with deterministic logic for accuracy and auditability.
Lead technically across our AI work - owning architecture, setting quality standards, and guiding other engineers.
Deliver AI consulting projects and contribute to our internal AI products.
Use AI tools as your default workflow to move fast without sacrificing quality.
Work directly with international clients and teams.
Where you have the skills or interest, contribute to the data engineering that powers our AI systems - pipelines, data models, and platforms (a plus, not required).
Your skills and experience
English: fluent, professional English (written and spoken) is a primary requirement for this role. You must communicate clearly and comfortably with international clients. We do not hire for this role without fluent English.
7+ years of professional software / AI engineering experience, including technical lead experience.
AI engineering (primary): 5+ years building production AI systems - deep, hands-on expertise with LLMs, embeddings, semantic search, and agents or AI workflows, with strong Python. This is the core of the role.
Technical leadership: proven experience leading engineers, owning architecture, and setting quality standards.
AI-first: proficient with AI tools for coding and daily work, and able to use them to deliver real, production-grade work. This is a core requirement, not a bonus.
Data engineering (a plus, not required): hands-on experience with data pipelines, ETL/ELT, and data models, or a strong willingness to grow into it. Experience with Azure and Microsoft Fabric is a bonus.
Deployment / MLOps experience is a plus.
Able to work Norwegian business hours: 12:00-21:00 Vietnam time (ICT), Monday to Friday.
Why you'll love working here
AI-first working environment - you'll work with modern AI tooling every day, on both client projects and our own products.
Remote and flexible, working Norwegian business hours (12:00-21:00 Vietnam time) - your mornings are free.
Salary range: USD 2,500-4,000 (full-time equivalent), depending on experience and engagement type.
For full-time roles: 13th-month salary, social insurance, company trips, learning and training, and other benefits according to company policies.
Work on real, complex AI problems, with strong technical ownership.
Opportunity to travel to Norway for onsite collaboration, or potentially relocate, depending on performance and project needs.
