Software Engineer, AI Platform
As a Software Engineer on the AI Platform team, you'll design and build the backend systems, integrations, and automation that power intelligent, AI-driven experiences across the organisation. You'll own services end to end, from rapid iteration to long-term reliability, while helping bring modern AI capabilities like retrieval, agents, and LLM tooling into production. This is a highly collaborative, engineering-first role: you'll work across teams to turn AI capabilities into scalable, well-instrumented systems, and you'll build the enterprise knowledge infrastructure (similarity search, vector databases, retrieval pipelines) that these systems depend on. The ideal candidate combines strong software engineering fundamentals, a solid grasp of modern AI system patterns, and clear technical communication.
- Design, build, and maintain backend systems, APIs, and automation workflows that power AI-driven applications on a high-volume platform.
- Develop custom integrations and connectors between internal services and external APIs.
- Build and operate enterprise knowledge systems - similarity search, vector databases, and retrieval pipelines - that power RAG and agent-based applications.
- Improve the reliability, performance, and scalability of automation and workflow systems.
- Implement observability, logging, alerting, and business metrics to measure system behaviour and continuously improve it.
- Contribute to platform tooling using both full-code solutions and workflow automation platforms such as n8n.
- Deliver clean, testable, production-ready code, with clear documentation and operational guides.
- Communicate technical concepts effectively to both engineering and non-engineering audiences.
- 2+ years of professional software engineering experience (required).
- Proficiency in one or more of Python, TypeScript, or C# (required).
- Experience designing, building, and operating production-grade services, integrations, or automation systems (required).
- Solid understanding of modern AI system fundamentals (RAG, agents, LLM tools) (required).
- Practical knowledge of vector databases, similarity search, and retrieval optimisation (required).
- Familiarity with APIs, microservices, and event-driven architecture (required).
- Strong focus on testing, observability, and performance for backend systems (required).
- Familiarity with low-code/no-code automation tools (such as n8n), or a willingness to learn them (required).
- Ability to thrive in a high-ownership, fast-paced environment, balancing rapid iteration with long-term maintainability (required).
- Ability to work effectively with both engineers and non-engineers (required).
