AI Engineer & Technical Consultant (Remote)

Location: Remote (Vietnam)

Working Hours: German Business Hours (CET/CEST) Approx. 2:00 PM to 10:00 PM ICT

Type: Full-time Contractor / Freelance

We are looking for more than just a developer; we are seeking a Thought Partner. We need an experienced AI Engineer to consult, design, and implement the infrastructure for an intelligent AI agent that scales eCommerce brands.

This agent will live inside Shopify and other tools, handling customer service, driving upsells, and adapting to each shop's unique logic and brand voice. You will play a critical role in taking our product from an MVP to a powerful, stable, and defensible platform.

• Architectural Leadership: Consult on and define the best architectural choices, including vector databases, model pipelines, hosting infrastructure, and third-party integrations.
• System Design: Design a scalable foundation for the agent's logic and knowledge retrieval (RAG pipelines, complex workflows, memory management).
• Core Development: Build the core components of the application, from API integrations to sophisticated prompt orchestration and context-aware decision-making.
• Strategic Innovation: Think in use cases. Proactively suggest automations, improvements, and features we may not have considered.
• eCommerce Integration: Deeply integrate the AI agent with the Shopify ecosystem to ensure it drives real business results (sales and support).

• Experience: Proven track record building or significantly contributing to AI agent systems. (Bonus if you have experience in Customer Service or eCommerce contexts).
• Technical Stack:
• Strong proficiency in backend languages (Python or Node.js).
• Deep familiarity with LLM APIs (OpenAI, Anthropic).
• Experience with orchestration frameworks (LangChain, Semantic Kernel, or custom solutions).
• Hands-on experience with Vector Databases (Pinecone, Weaviate, Chroma).
• eCommerce Knowledge: Familiarity with the Shopify API is highly preferred. Experience with Klaviyo, Gorgias, or similar tools is a plus.
• Mindset: You are a technical leader who thinks in systems and edge cases, not just code. You don't just take ticketsyou own the technical direction.
• Language: Professional proficiency in English (Written and Spoken).

• You must be available to work during German Business Hours.
• This typically requires availability between 2:00 PM and 10:00 PM / 11:00 PM Vietnam Time.
• Collaboration and overlap with the European team are essential for this role.

• Impact: You won't just be maintaining legacy code; you will be building a core product from the ground up.
• Autonomy: We value your consultancy and technical direction. You will help shape the product roadmap.
• Remote Culture: Work from anywhere in Vietnam, provided you have a stable internet connection and can meet the time zone requirements.
