We’re partnered with a pioneering AI organisation reshaping how global enterprises transform chaotic, unstructured data into reliable, production-grade insights. Their AI-native platform blends intelligent agents, automation, and intuitive interfaces to accelerate the entire data lifecycle — from generation and refinement to deployment at scale.

 
This is a high-impact role for an engineering leader who thrives at the intersection of LLMs, agentic systems, and large-scale cloud architecture, and who can lead both technically and strategically.

• Build and optimise LLMs, RAG pipelines & vector search
• Architect high-scale cloud systems (AWS/GCP, k8s)
• Prototype rapidly, ship often, mentor engineers
• Own roadmap, technical direction & cross-functional collaboration

 
What you’ll bring:

• 7+ years in ML/AI or distributed engineering
• Deep expertise in at least one: LLM fine-tuning, agent frameworks, RAG/vector DBs
• Strong Python + experience with Go/Java/Scala
• Proven 0→1 and 1→10 product delivery
• Leadership across architecture, execution and technical strategy

 
Benefits:

• Top-tier health cover
• Monthly wellness/remote-work allowance
• Flexible PTO + professional development budget
• Ownership over high-impact AI projects
