How you can help make a better world of work We're building the platform that makes AI possible across Culture Amp. This is a Staff‑level role in our AI Platform team, responsible for the infrastructure, governance, and tooling that enables product teams to ship AI‑powered features safely and at scale. What you'll do You'll own the systems that sit between our product teams and the AI capabilities they need: LLM gateways, vector storage, retrieval infrastructure, and the guardrails that keep it all compliant and cost‑effective. Design and operate the platform services that power AI features across Culture Amp, including inference pipelines, embedding storage, and retrieval systems. Build a scalable approach to vector search across diverse categories of unstructured data (survey responses, performance feedback, company documents). Drive MLOps and LLMOps practices across the organisation, including observability, cost management, and reliability. Ensure AI is used responsibly by implementing guardrails, security controls, and data compliance measures. Partner with data scientists on the team to productionise models and evaluate new AI capabilities. What makes this interesting AI is central to Culture Amp’s product roadmap. Coach, our AI assistant, is changing how we empower managers and leaders to build better workplaces, and this platform is what makes that possible.
