Immediate Start
£100k - £150k Annual
Full-Time - Remote

Backend Engineer (AI) | Python | Node.js | Kubernetes | LLMs

Fully Remote

Build the Back End systems powering the next generation of AI-native applications.

We're partnering with an exciting AI startup on a mission to redefine how people interact with everyday productivity tools. Rather than adding AI as an afterthought, they're building an intelligent assistant that helps users organise work, complete tasks, and automate complex workflows with minimal prompting.

They're now looking for a Python Backend Engineer - Technical Lead to build the infrastructure that powers every AI interaction across their platform.

The Role

You'll own the Back End services sitting between foundation models and end users, designing highly scalable, low-latency systems that deliver fast, reliable AI experiences.

This is a hands-on engineering role where you'll work on inference pipelines, orchestration, distributed systems, and production infrastructure, ensuring AI features perform reliably at scale.

What You'll Be Doing

  • Design and build Back End services supporting AI-powered features
  • Develop inference pipelines and orchestration layers around LLMs
  • Optimise latency, throughput, caching, batching and streaming
  • Own production monitoring, logging, alerting and incident response
  • Improve system reliability, scalability and observability
  • Collaborate closely with product, Front End and ML engineers to deliver production-ready AI solutions

What We're Looking For

  • Strong commercial Back End engineering experience
  • Python and/or Node.js expertise
  • Experience building high-throughput, low-latency distributed systems
  • Knowledge of Kubernetes and Docker
  • Experience with SQL and NoSQL databases
  • Familiarity with modern AI technologies including LLMs, embeddings or AI inference pipelines is highly desirable
  • Comfortable debugging complex production systems and driving continuous improvement

Tech Stack

  • Python
  • Node.js
  • PyTorch
  • OpenAI, Anthropic & open-source LLMs
  • SQL & NoSQL
  • Kubernetes
  • Docker

Why Join?

You'll become part of a small, exceptionally talented engineering team building AI products from the ground up. This is an opportunity to have genuine ownership, influence technical direction, and solve challenging engineering problems at the intersection of distributed systems and artificial intelligence.

If you're passionate about building reliable, production-grade AI infrastructure and want to work on technology used by millions of people, we'd love to hear from you.

Apply today to learn more about this opportunity.
