Salary: Up to $150,000

We have partnered with a fast-growing, product-led technology company building AI-powered systems to supercharge internal teams and deliver intelligent customer-facing solutions.

As the business scales, they’re hiring an AI Engineer to design and ship high-impact AI systems across internal tooling, developer experience, and production-grade customer applications.

What You’ll Do as an AI Engineer:

  • Design and ship AI-powered internal tooling that increases productivity across all teams.
  • Build AI-enhanced developer workflows, coding assistants, and automation systems.
  • Develop and maintain customer-facing AI support pipelines and production LLM systems.
  • Architect and scale Retrieval-Augmented Generation (RAG) systems for large knowledge bases.
  • Design and orchestrate agent and multi-agent architectures for complex task execution.
  • Integrate LLMs via providers such as OpenRouter, optimising for cost, latency, and performance.
  • Fine-tune domain-specific LLMs and continuously improve model performance.
  • Build and maintain workflow automation pipelines using tools like n8n and LangChain.
  • Implement LLM observability and monitoring across production systems.
  • Continuously evaluate emerging models, frameworks, and AI tooling to keep the company at the cutting edge.

What We’re Looking For in an AI Engineer:

  • Proven experience shipping AI systems into production environments.
  • Strong proficiency in Python and/or TypeScript/JavaScript.
  • Deep experience with LangChain, RAG systems at scale, and LLM fine-tuning.
  • Hands-on experience building agent or multi-agent architectures.
  • Experience with workflow automation tools such as n8n.
  • Strong understanding of model selection across providers and cost/performance trade-offs.
  • Familiarity with LLM observability tools (e.g., LangFuse, Weights & Biases).
  • Comfortable with basic DevOps and deploying AI systems reliably.
  • A product manager mindset — proactively identifying opportunities, understanding real user needs, and driving adoption of internal tooling.
  • Nice to Have's as an AI Engineer:
  • Experience with voice AI or multimodal systems.
  • Contributions to open-source AI projects.
  • Experience working with AI-native developer tools and modern AI IDE workflows.

This is a rare opportunity for an AI Engineer to architect and scale AI systems at the core of a company’s operations, directly influencing productivity, product capability, and long-term technical strategy.
