Job Description & How to Apply Below

The Role Purpose

We are seeking an AI Engineer to join our team, with a primary focus on designing, developing, and maintaining production-grade software solutions that leverage Large Language Models (LLMs), embedding models, and other generative technologies. This role emphasizes building scalable, reliable, and secure agentic solutions (including multi-agent systems) for external market-facing products and internal enterprise enablement.

The successful candidate will combine strong software engineering fundamentals with deep practical capability in retrieval-augmented generation (RAG), knowledge management, prompt/context engineering, model/tool orchestration, and AI governance guardrails.

The successful candidate will play a key role in building scalable systems for external market-facing products.

Your Responsibilities
  • Design, develop, test, and deploy end-to-end GenAI-enabled software solutions (services, APIs, workflows, and product features).
  • Build agentic systems, including multi-agent architectures, tool-use patterns, orchestration flows, and production tooling integrations.
  • Design and implement RAG pipelines for both product and enterprise contexts, including knowledge-based curation, ingestion, document processing, chunking strategies, embedding generation, retrieval tuning, and answer grounding.
  • Develop and operationalize robust prompt and context engineering practices (prompt templating, context window management, instruction hierarchy, tool routing, and response formatting).
  • Implement agent memory management patterns and frameworks to support short-term and long-term memory, personalization, and session continuity (where applicable).
  • Integrate and operate model providers and runtimes for production use-cases, including hosted APIs and self-hosted inference, optimizing for latency, cost, throughput, and reliability.
  • Develop microservices and APIs that expose GenAI/agent capabilities to web applications and downstream systems; maintain strong engineering standards for versioning, observability, and backward compatibility.
  • Design and maintain data stores supporting GenAI applications, including relational, vector, and graph patterns to enable retrieval, reasoning, and relationship-aware experiences.
  • Implement AI Governance practices: apply and monitor guardrails (policy enforcement, content filtering, PII handling, prompt injection defences, auditability, and safe tool execution).
  • Evaluation and monitoring approaches for GenAI systems (quality, grounding, safety, latency, cost), contributing to continuous improvement initiatives.
  • Collaborate with cross-functional teams (Product, Engineering, UX, Data/ML, Security, Compliance) to translate business requirements into technically sound solutions.
  • Participate in code reviews, architectural discussions, and agile planning sessions; contribute to internal standards, patterns, and reusable components.
  • Maintain and enhance legacy systems where required, integrating GenAI functionality safely without compromising stability.
Qualifications & Experience

Educational Background:

  • Bachelor’s degree in Computer Science, Information Technology, Data Science, Artificial Intelligence, Software Engineering, or equivalent
  • Postgraduate qualification in Artificial Intelligence, Machine Learning, Data Science, or Applied Mathematics is advantageous
  • Relevant certifications are advantageous (examples include Microsoft Azure AI Engineer, AWS Machine Learning, or similar cloud/AI certifications).

Work Experience:

  • 1-3 years of experience in delivering production-grade software (greenfield and brownfield), including backend services and customer-facing modules.
  • Proven hands-on experience building and deploying GenAI solutions in production, including LLM-powered features, RAG-based systems, or agentic workflows.
  • Experience implementing governance controls and operational monitoring for GenAI systems in real-world environments.
  • Strong practical exposure to modern software engineering practices: CI/CD, testing, code review, observability, and secure API design.

Knowledge:

  • Strong understanding of LLM/embedding fundamentals as applied in production systems (retrieval, grounding, context shaping, evaluation, and failure modes).
  • Knowledge of multi-agent patterns, tool/function calling (MCP), workflow orchestration, and safe execution boundaries.
  • Understanding of data management strategies for GenAI (document pipelines, vector search, graph relationships, and relational integrity).

Familiarity with data privacy principles, security-by-design, and governance expectations relevant to enterprise-grade AI solutions.
