Senior AI Engineer – Agent Systems & RAG (LangChain / CrewAI / Python / N8N)

Type: Full-timeCompany: Friday Media Group (FMG)About the Role:

We are building a next-generation AI Agent Platform across our group, alongside deploying specialised AI agents within our products and business wide operations. We are looking for a hands-on AI Engineer with strong experience in:

• building and deploying AI agents
• designing production-grade RAG (Retrieval-Augmented Generation) systems
• working with frameworks such as LangChain and CrewAI

This is not a research role.

We are looking for someone who has built and shipped real AI systems into production environments .

What You Will Be Working On:

• Designing and building multi-agent systems for real-world business workflows
• Developing agents across:
• Finance
• Customer support automation
• Marketing workflows
• Sales and CRM automation
• Building RAG-powered systems to enable agents to retrieve and reason over internal data
• Integrating AI agents with real systems:
• NetSuite
• N8N 
• CRMs
• Email systems
• Internal APIs and databases
• Creating hybrid systems combining rules, workflows, and LLM reasoning
• Implementing structured outputs (JSON, workflows, automation triggers)

Key Responsibilities:

• Build, test, and deploy AI agents end-to-end
• Design agent architectures (single-agent, multi-agent, tool-using agents)
• Develop and optimise RAG pipelines , including:
• document ingestion and chunking strategies
• embedding pipelines
• vector search and retrieval optimisation
• grounding LLM outputs with internal data
• Implement context management, memory, and tool usage within agents
• Hands on experience with N8N or similar workflow automation tools
• Integrate agents with external APIs, databases, and SaaS platforms
• Build evaluation, monitoring, and logging systems for agent performance
• Optimise for accuracy, latency, and cost efficiency
• Work closely with product teams to translate workflows into AI-driven systems

Required Skills & Experience:

• Strong experience in Python
• Hands-on experience with:
• LangChain
• CrewAI (or similar multi-agent frameworks)
• Proven experience building production-grade AI agents
• Strong experience with RAG systems , including:
• embeddings and vector search
• retrieval optimisation (filters, hybrid search, ranking)
• grounding outputs with structured and unstructured data
• Experience working with vector databases such as:
• Pinecone
• or alternatives (Weaviate, FAISS, etc.)
• Experience with LLM APIs (OpenAI, Gemini, etc.)
• Strong understanding of:
• prompt design
• tool/function calling
• memory and context handling

Preferred (Nice to Have):

• Experience building AI agents in:
• Finance (AP, AR, reporting, forecasting)
• Marketing automation
• Sales / CRM workflows
• Customer support systems
• Experience with fine-tuning or adapting models , including:
• instruction tuning
• domain adaptation
• evaluation of fine-tuned vs prompt-based approaches
• Experience with advanced RAG patterns:
• hybrid search (vector + keyword)
• re-ranking models
• agent-driven retrieval strategies
• Experience with:
• Supabase / PostgreSQL
• FastAPI or similar backend frameworks
• event-driven or workflow-based systems
• Exposure to NetSuite or financial systems is a strong plus

What We Are Looking For:

• Someone who has actually built and deployed AI agents , not just experimented
• Strong problem solver who can translate business workflows into AI systems
• Comfortable working in a fast-moving, product-driven environment
• Ability to balance:
• LLM reasoning
• deterministic rules
• system design

Important Note

We are not looking for basic “chat with documents” implementations.

We are building production-grade AI systems integrated with real business workflows and decision engines .

Why Join Us:

• Work on real-world AI deployment , not just prototypes
• Build systems that directly impact business operations
• Opportunity to shape a group-wide AI platform (FridayOS vision)
• Exposure to multiple domains: finance, marketplaces, SaaS, recruitment
