The Senior Developer is a builder. You will write the code behind our AI capabilities: agents, knowledge systems, and analytical applications used by analysts on live client work. This is a small team where the person who designs a component is usually the person who ships it, and where what you build reaches users in weeks rather than quarters.

What You'll Build:
Interpretation. Systems that take the output of an analysis and produce business-relevant interpretation — what the numbers actually mean for a given client and category.

Media Investment planning. Analytical tooling that supports budget allocation and media investment planning decisions.

- Implement LLM-based components: agents, tool interfaces, structured outputs, and the orchestration that connects them.
- Build and run the evaluation harnesses that tell us whether a change improved an agent or merely changed it. Non-deterministic systems need tests too, and building them is part of the job rather than an afterthought.
- Implement context and retrieval strategies, and contribute evidence to the decisions about which appr
