AI & Data Engineer

You will operate at the intersection of Data Engineering, Data Science, and modern AI/ML systems, taking ownership of initiatives that directly shape product and business outcomes. We need someone with genuine breadth — equally comfortable designing scalable data pipelines as they are building agentic AI architectures — and with the curiosity to keep pace with a space that is moving faster than almost any other in software engineering.

You will bring deep technical expertise across the full AI/ML stack alongside the leadership qualities to mentor colleagues, challenge assumptions, and drive a culture of engineering excellence. Crucially, you will not just set direction — you will get your hands dirty and build it too.

This role spans two interconnected disciplines. We are looking for strong coverage across both.

Lead the refactoring of legacy infrastructure into highly scalable, secure, and multi-tenant data pipelines that power our Security Portfolio Intelligence platform.

Own data quality, governance, and security end-to-end: establishing robust validation frameworks, automated alerting, and compliance-ready data modeling for highly regulated enterprise clients.

Champion pragmatic AI: ruthlessly identify where LLMs can be replaced by leaner, more cost-effective classical ML models, ensuring optimal performance and cost-efficiency.

Evolve our data architecture: champion the appropriate pattern for the job, whether that's a GraphDB, vector stores, and more standard SQL/No

SQL structures, all whilst ensuring scalability and long-term maintainability.

Establish and promote good data modelling practices across the organisation — schema design, query optimisation, and a sensible approach to data governance.

Work across a range of storage paradigms: SQL (PostgreSQL, MySQL), vector databases (pgvector and equivalents), and graph databases (Neo4j or similar).

Design and ship agentic AI pipelines and multi-agent reasoning systems that solve real business problems — content review, classification, enrichment, and beyond.

Lead the evaluation and adoption of emerging AI/ML tooling:
Vertex AI, Google ADK, AWS Sage Maker, Azure ML, and next-generation LLM frameworks.

Establish LLMOps practices: formal evaluation pipelines, regression testing, and quality baselines so we always know whether our AI systems are improving or declining.

Identify where Large Language Models can be replaced by leaner, more cost-effective traditional ML models — and deliver those replacements.

Build NLP-powered systems, including classifiers, semantic search, and potentially fine-tuned or custom-trained models where the use case justifies it.

Drive the auto-generation of marketing content and other AI-powered product features, working closely with Product to turn ideas into production systems.

Bring your own ideas to the table. If you see an opportunity we have not spotted, we want to hear it — and we will give you the space and support to explore it.

Mentor and collaborate with engineers across the team, raising the collective bar for AI/ML quality, reproducibility, and best practice.

Run tech-sharing sessions; keep the team current on fast-moving developments in the AI/data space.

Contribute to hiring: interview, assess, and help build the team you want to work in.

7+ years of professional experience across Data Engineering, Data Science, or Machine Learning roles — with meaningful exposure to both the data and AI/ML sides of that spectrum.

Hands-on experience designing and shipping agentic AI systems and multi-agent architectures (Lang Chain, Lang Graph, Auto Gen, Google ADK, or similar frameworks).

Strong working knowledge of Large Language Models: prompt engineering, evaluation, and responsible deployment in production.

Experience with Cloud ML platforms — at least one of Vertex AI (GCP), Sage Maker (AWS), or Azure Machine Learning.

Expertise in Python for data processing, model training, and API development.

Solid understanding of classical ML and NLP: ability to identify when a simpler model outperforms an LLM in production and to deliver that alternative.
