Applied AI Engineer - Production AI Systems for Industrial Workflows

Applied AI Engineer | ~£150K + Equity

London, UK

About the Company

This early-stage startup has recently closed a heavily oversubscribed seed round from top-tier technology investors and is now preparing for its Series A. It is building AI-native workflows that enable industrial sectors such as aerospace, healthcare, manufacturing, and energy to operate with the speed and efficiency traditionally associated with software businesses. Their platform combines large language models, document intelligence, and agentic workflows to automate complex operational processes that have historically depended on manual effort, fragmented systems, and unstructured data.

About the Role

This is a highly product-focused engineering role at the intersection of AI, software engineering, and real-world customer problem solving. You will design, build, and deploy production AI systems that directly power customer workflows. Rather than focusing on pure research or open-ended experimentation, you will apply LLMs, agents, evaluation systems, and document-understanding technologies to concrete operational problems in industrial environments. The environment is fast-paced, highly autonomous, and ideal for engineers who enjoy ownership, ambiguity, and shipping quickly. You will work closely with founders, customers, and cross-functional teams to deliver customer-visible impact from day one.

Responsibilities

• Designing and deploying production-ready AI features across customer-facing products and internal workflows.
