We help businesses attract, engage, and retain top talent through strategic rewards, recognition, and well-being solutions. As we continue to expand our business, we have an opportunity for a hands-on AI Engineer who is excited about turning real-world challenges into smart, scalable solutions.

You will work with the latest third-party AI services, build streamlined workflows and craft high-impact prompts that boost our internal tools, speed up developer productivity and elevate the customer experience. Build and deliver production-ready AI and Generative AI solutions using LLMs, RAG architectures, agents, and responsible AI practices.

Use AI coding assistants such as Cursor, GitHub Copilot, and Claude Code to accelerate development while maintaining ownership of outcomes and documenting best practices and repeatable patterns. Manage cloud infrastructure and platform operations, including AWS, Kubernetes, CI/CD pipelines, Terraform, monitoring, performance optimisation, and cost control.

Design, develop, and maintain backend services in Python, and contribute to React, TypeScript, and PHP codebases when required. Lead evaluation and iteration cycles, including defining and tracking offline and online metrics, running A/B tests, meeting latency and cost targets, implementing human-in-the-loop validation, and ensuring robust observability.

Implement and maintain retrieval pipelines using embeddings, vector databases, hybrid search methods, and effective chunking strategies. Improve internal AI development tooling, including shared libraries, SDKs, and reference implementations for RAG, tracing, prompt management, and evaluation. Contribute to internal enablement and capability-building activities across the organisation.

Partner with Security, Legal, and Data teams to define AI policies, review risks, and ensure privacy, PII protection, and regulatory compliance. Mentor peers, conduct code reviews, and share knowledge to elevate engineering standards across the organisation.

Proven experience in shipping production-grade AI solutions. Applied AI expertise across LLMs, RAG, agentic workflows, prompt engineering, embeddings, vector databases, hybrid search techniques, and effective chunking strategies.

Strong Python as a primary language, with solid testing practices and CI/CD experience; able to contribute when needed in React, TypeScript, and PHP or Node.js. Cloud and platform engineering skills, including AWS, Kubernetes, Docker, infrastructure as code, and modern observability tooling.

Familiarity with LLM tooling ecosystems such as LangChain or LlamaIndex, agentic AI frameworks, vector stores, tracing and logging tools, prompt management platforms, and evaluation frameworks. Strong data engineering capabilities, including dataset creation and validation, ETL development, SQL schema design, and the definition and tracking of meaningful product and model metrics.

Solid understanding of ML fundamentals and experimentation, including metric design, error analysis, model selection, and performance tuning. A strong security and governance mindset, with the ability to communicate clearly with both technical and non-technical audiences, and a high level of ownership from discovery through production and iterative improvement.
