AI Data Engineer - Rockerbox

Join to apply for the Staff AI Data Engineer – Rockerbox role at Double Verify
.

Rockerbox is building the next generation of marketing intelligence, and we’re looking for someone to help us build the AI systems everyone else just theorises about. As a Staff AI Data Engineer, you’ll research, design, and architect data systems purpose‑built for AI agents, automations, and decisioning engines. You’ll also apply data science and model‑tuning techniques to optimise LLMs and solve complex marketing challenges for our clients.

If you enjoy turning high‑volume data into clean, powerful systems—and you want your work to drive real business outcomes rather than just dashboards—this role puts you right at the centre of the action.

• Apply bleeding‑edge AI theory to the design and implementation of large‑scale data systems that feed AI agents and autonomous workflows.
• Use data science techniques to fine‑tune, evaluate, and optimise LLMs for marketing‑specific tasks: attribution insights, anomaly detection, summarisation, classification, and automated recommendations.
• Build end‑to‑end automations using LLMs, internal data, and external signals to eliminate repetitive human tasks.
• Build AI‑driven automations that reduce manual work across Rockerbox and unlock new client‑facing capabilities.
• Design retrieval, orchestration, and memory layers that make our AI agents smarter over time.
• Establish best practices for AI data quality, observability, experiments, and safety.
• Lead R&D initiatives: rapid prototyping, experimentation, model evaluations, and productionisation.
• Mentor data scientists and engineers across the organisation to raise the bar on LLM use company‑wide.

• 8+ years of experience in data engineering, AI, ML platforms, or large‑scale distributed systems.
• Hands‑on experience integrating LLMs into production systems (OpenAI, fine‑tuning, embeddings, RAG, vector stores, or custom agent orchestration).
• Strong understanding of experimentation, model evaluation, and performance tuning.
• Think in systems: storage, retrieval, metadata, reliability, latency, failure modes.
• Ability to work from ambiguity to execution — you’re comfortable being the first to figure something out.
• Strong communication skills: you can explain trade‑offs, scope decisions, and technical strategy clearly.
