Job Description

Senior AI Engineer (AI-Facing Systems)

This is one of those rare engineering roles that actually lives up to the hype. Join and immediately contribute to a high calibre growing AI team building real, production-grade AI systems. Their product is already in the hands of paying customers, and demand is outpacing bandwidth. They need someone exceptional to help them scale.


You’ll design and ship backend architecture that powers intelligent agents that are used directly by the customers of this growing SaaS product company.

Why this role matters
This isn’t basic software, it’s orchestrating distributed systems around foundation models and vector databases, with serious up-time and performance requirements. You will be one of their core AI Engineering team shaping the roadmap of a company that is already seeing the benefits of implementing Agentic AI in one of their core products. This will open opportunities for you to grow with the company and realise career growth as the team grows. 


There’s AI in the stack, but it’s the hard part of AI. You’ll work with model scaffolding, low-latency services, embedding search, and fine-tuning pipelines. You don’t need to have done it all before, but you should be deeply curious and ready to learn fast.
You’ll thrive here if you:

  • Have strong experience in backend-heavy roles using Python and/or C#

  • Have worked in a product environment, real-time APIs, or performance-critical infrastructure

  • Have meaningful experience with AI projects, such as finetuning models, using Langchain, or working with vector databases like pgvector, Pinecone, or Neo4j

  • Have shipped serious features end-to-end in a fast-paced team

  • Want to help build not just code, but a company

  • Bonus points if you’ve worked on knowledge graphs, LLM integration, or embedding pipelines. 

 
What’s in it for you

  • Massive impact. You’ll be building the product, not maintaining it.

  • Serious technical stretch. This is complex, greenfield work.

  • Collaborate directly with an amazing and ambitious team. 

  • Speed and autonomy. Work with a sharp, lean team that values customer experience.
