Fourth is the world’s largest and fastest-growing global leader of end-to-end restaurant and hospitality management technology solutions. We pride ourselves on delivering a world-class SaaS experience for our clients by building long term partnerships starting from the first phone call. We know our recipe for success at Fourth is our amazing team... and that starts with hiring the right people!

Interested in joining our smart, fun, and talented team?

We are looking for a senior, hands‑on AI Solutions & Engineering Lead to design, build, and productionize AI solutions used across Fourth’s enterprise operations.

This role owns the technical foundations for AI in production - ensuring solutions are scalable, reliable, well‑governed, and integrated with enterprise data and systems.

The AI Solutions & Engineering Lead is reporting to Director of Enterprise Data & Intelligence. You will join the Enterprise Data & Intelligence team, which builds the shared data, analytics, and AI foundations that power decision‑making and operations across Fourth - not individual products.

The AI Lead is at the forefront of reshaping how Fourth operates as a business - starting hands-on with production AI systems and growing into a standards‑setting technical leader defining the architecture, governance, and direction for AI used across the entire enterprise.

What’s in it for you:

· Enterprise‑wide impact beyond a single product

· Challenge of connecting multiple internal services and third-party systems into coherent, reliable AI solutions

· Real ownership of production AI architecture and engineering decisions

· Hands‑on technical leadership

· Opportunity to set standards and patterns as AI scales across Fourth

Responsibilities:

· Own AI engineering and architectural decisions across enterprise solutions

· Design and build production‑grade AI systems and pipelines

· Take AI solutions from prototype to reliable production

· Define engineering standards, quality bars, and production readiness

· Shape feasibility, prioritization, and technical approach for AI initiatives in partnership with the Director, without owning overall AI strategy

· Translate business problems into scalable, technically sound AI solutions

· Work with Data, Security, Legal, Compliance and others on safe AI delivery

Requirements:

· 5+ years experience in machine learning, AI engineering or software development, with a demonstrated track record of deploying machine learning models and AI solutions in production environments

· Strong Python skills for building production AI services

· Hands‑on experience running LLM‑based systems in production

· Experience with RAG architectures, embeddings, and vector search

· Proven ability to design scalable, maintainable systems and APIs

· Solid understanding of production operations (monitoring, logging, error handling)

· Cloud deployment experience (Azure preferred)

· Strong understanding of data pipelines, SQL, and data quality

· Working knowledge of AI governance, access control, and responsible AI practices

Benefits and Culture:

· 25+ days off, as well as birthday day off and 4 charity days off per year

· Flexible start and end of the working day and hybrid working mode, including a combination remote and in the office

· Team-centric atmosphere

· Encouraging healthy lifestyle and work-life balance including supplemental health insurance

· New parents bonus scheme
