Role
Who you are
- 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
- You 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 tradeoffs, scope decisions, and technical strategy clearly
What the job involves
- 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 optimize LLMs and solve complex marketing challenges for our clients
- 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 optimize LLMs for marketing-specific tasks: attribution insights, anomaly detection, summarization, 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 productionization
- Mentor data scientists and engineers across organization to raise the bar on LLM use company-wide
Our take
The importance of digital advertising continues to grow, but it can be difficult for companies to protect their brand identity online. DoubleVerify solves this problem using software that monitors campaign performance in real-time.
Since it was first launched, DoubleVerify has successfully carved out an impressive market share, and now boasts customers such as digital advertising giant Facebook as long-time customers. Its success is largely owed to the quality of its technology, which far outperforms that of its rivals. DoubleVerify has consolidated its success by expanding the range of languages its tools support. It has also expanded into new markets such as Australia and New Zealand, a key indicator of the company’s continued growth.
The digital ad space is changing constantly, and DoubleVerify will need to remain as agile and adaptive as it is at present in order to compete with rivals such as Tremor and Quantcast. But with a 2021 IPO, several recent rounds of funding and new product releases, it looks set to tackle its competitors head on and stay ahead of the game.
