The Role
This company builds a global tax automation platform, solving genuinely complex regulatory problems for large digital businesses. They're backed by leading investors and have significant ARR, with a clear mandate to apply AI to a domain rich in structured data and multi-jurisdiction edge cases.
This isn't a research role disconnected from production. You'll be the first Staff AI Engineer, shaping how LLMs and agentic systems are applied across the product, from prototyping intelligent workflows to building natural language interfaces. Expect end-to-end ownership, defining the playbook rather than inheriting one.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits

- Deep, hands-on experience with LLMs, prompt engineering, and agent frameworks, including production experience with RAG architectures.
- Proven ability to design and implement evaluation pipelines for AI models.
- Strong product instincts combined with technical depth; you can articulate AI choices in both commercial and technical terms.
