London (Hybrid) | £120,000–£160,000 + Equity

As a Backend Engineer, you’ll join a growing team working at the forefront of AI infrastructure.

What You’ll Be Doing:

Building and evolving APIs that serve as the backbone for internal systems and customer-facing applications Scaling the platform to support heavy, multi-tenant usage patterns and high-throughput AI workloads Applying foundation models (GPT-4.1, Claude 4, Gemini 1.5 and successors) to real-world, multi-modal data challenges Shipping to production daily in collaboration with Product and Design to solve real user problems Playing an active role in shaping team goals, defining technical metrics, and prioritising outcomes over ticket-chasing

Your Background:

Hands-on experience with functional programming (Elixir is a plus, but other languages like Scala, Haskell, Clojure, Go, Node.js, or F# are welcome) Proven track record of building and scaling distributed backend systems Solid understanding of infrastructure-as-code and cloud orchestration (AWS, Terraform, Docker) Familiarity with queue management, observability tooling, and shipping in fast-paced environments Awareness of GenAI and prompt engineering, or a keen interest to develop expertise in this area A self-starter attitude, with a strong sense of product ownership and a passion for solving end-user challenges

This is a unique opportunity to work on real-world applications of cutting-edge AI, contributing to a platform where engineering excellence and product thinking go hand-in-hand. If you're looking for a role with tangible impact and huge technical scope, we’d love to hear from you. Reach out today to start the conversation.
