IT is at the core of their organization, with more than 30 product teams and 10 platform teams focused on building high-quality products and services for their customers.

AI is becoming a key driver of innovation, with ongoing initiatives to embed AI into core processes to improve efficiency, reduce risk, and enable better decision-making.

THE ROLE INVOLVES:

As an Experienced AI/ML Engineer, you design and build production-grade AI systems, working at the intersection of engineering, data, and business use cases.

You will focus on modern AI architectures, including LLM-powered systems, agent-based workflows, retrieval mechanisms, and evaluation pipelines, contributing to scalable and reliable AI solutions.

This role offers the opportunity to shape how AI is applied in a real-world, high-impact environment, with direct influence on architecture, design decisions, and best practices.

Responsibilities

Core AI Engineering

• Design and implement LLM-based applications and agent workflows (tool usage, orchestration, context handling).
• Build and optimize retrieval and memory systems (vector search, embeddings, session and long-term memory).
• Develop robust evaluation pipelines (automated + human evaluation, benchmarking, quality tracking).
• Integrate AI services with cloud platforms (e.g., AWS Bedrock) and enterprise systems.
• Ensure performance, scalability, and reliability of AI systems in production.

Data & AI Lifecycle

• Build and maintain data flywheels (instrumentation, dataset curation, continuous improvement loops).
• Support fine-tuning strategies (e.g., LoRA, prompt engineering, evaluation-driven refinement).
• Translate business problems into AI-driven solutions and architectures.

Architecture & Best Practices

• Contribute to AI architecture decisions (tooling, frameworks, integration patterns).
• Establish standards for evaluation, testing, and deployment of AI systems.
• Improve observability and monitoring of LLM-based solutions (quality, latency, cost).

Collaboration

• Work closely with business stakeholders and product teams to deliver fit-for-purpose AI use cases.
• Collaborate with engineers and data teams to ensure end-to-end solution integration.

Requirements

Technical Skills

• 5+ years of experience in software engineering / ML engineering

• Hands-on experience working with LLMs (via APIs or SDKs)
• Experience building agent-based or multi-step AI workflows
• Experience with cloud AI platforms (e.g., AWS Bedrock or similar)
• Strong understanding of:
  • Retrieval-Augmented Generation (RAG)
  • Embeddings and vector databases
  • Evaluation methodologies for LLM systems
• Experience deploying AI systems in production environments
• Understanding of system design, scalability, and performance optimization

Nice to Have

• Experience in regulated environments (e.g., financial services)
• Exposure to fine-tuning techniques and model optimization
• Familiarity with modern AI tooling ecosystems (LangChain, LlamaIndex, etc.)
• Relevant university degree (Computer Science, AI, or similar)
• Experience with AI platform ecosystems and tooling
• Interest in emerging AI trends and technologies

Soft Skills

• Strong analytical thinking and structured problem-solving skills
• Excellent verbal and written English level - clear and effective communication skills
• Entrepreneurial/Ownership mindset and proactive approach
• Ability to collaborate closely with business stakeholders
