We’re reinventing payments. In less than four years, Dojo disrupted the market to become the largest and most loved acquirer in the UK. Our payments infrastructure, purpose-built for in-person commerce, is game changing. Now, over 150,000 customers across four countries choose to transact billions with us every year. But we’re just getting started. Our people are the driving force behind our success. They are our greatest investment and our ultimate competitive advantage. We hire exceptional people and give them the autonomy, trust, and ownership to thrive. The results take care of themselves.
The role... AI Engineering is all about making AI a reality in production not just prototyping. It means building the frameworks and platforms that allow Dojo to prototype AI solutions quickly and then take the best of those into production with the right guardrails, scalability, resilience, and reliability in place. We’re not here just to experiment. We’re here to make AI usable, safe, and impactful across the business by combining strong engineering with practical AI know-how.
- Giving teams the tools to prototype fast and learn.
- Creating the platform and infrastructure to run AI solutions at scale.
- Embedding security, monitoring, and governance so AI can be trusted.
- Designing for resilience and performance so solutions last, not just launch.
AI Engineering at Horizon is about building the rails that take AI from idea to production, safely and at scale. As an AI Platform Engineer, you’ll be part of the team designing and running the core AI platform. You’ll work on APIs, pipelines, observability, security, and orchestration, ensuring our AI solutions can move from experiment to production smoothly. This role is about building the foundations of AI adoption — if you enjoy combining distributed systems, cloud engineering, and AI tooling into something bigger, this is it.
What you will do…
- Design and build the AI platform that powers LLMs, agents, and other AI solutions across Dojo.
- Develop APIs, SDKs, and tooling that allow product teams to consume AI capabilities at scale while having great developer experience.
- Implement orchestration for multi-model and multi-service workflows (e.g., LangGraph, Crew AI, Google Agent Development Kit, agentic frameworks).
- Build and manage vector search and retrieval systems to support RAG and knowledge integration.
- Build robust monitoring, logging, and guardrails to ensure AI systems are safe, observable, and compliant using solutions like Langsmith, Opik, Prometheus and Grafana.
- Automate infrastructure and model deployment with Kubernetes, Terraform, and CI/CD pipelines.
- Partner with security, compliance, and product to ensure safe use of AI in production.
- Stay on top of AI platform trends, open-source tools, and emerging patterns — bringing best practices into our stack.
What you'll bring...
- Strong software engineering or platform engineering background (Python/GO/Java; Go/Java/.NET a bonus).
- Solid experience with distributed systems, microservices, and cloud-native architecture (GCP preferred).
- Hands-on experience with Kubernetes, service mesh, and event-driven systems.
- Familiarity with LLM orchestration frameworks (LangChain, LangGraph, CrewAI, GCP ADK or similar).
- Experience with vector databases (FAISS, Pinecone, Weaviate, Vertex Vector Search) and RAG pipelines.
- Knowledge of MLOps/AI infra tools (MLflow, VertexAI, Ollama, OpenRouter etc).
- Strong CI/CD and infrastructure-as-code skills (Terraform, Helm, etc.).
- Good understanding of AI governance, monitoring, and responsible AI practices.
- Comfort balancing speed (PoCs) with robustness (production-ready systems).
