The Role
This company builds AI agents that automate complex financial workflows, generating client-ready documents 20x faster than traditional methods. They're transforming how major financial institutions operate, backed by leading investors in one of the largest Series A rounds in the sector. They are one of the fastest-growing enterprise AI platforms globally.
This isn't a feature-shipping role. As a Lead Front-End Engineer, you'll own the front-end craft across the entire product, defining the patterns and guidelines that every engineer — even those working on agentic tooling — codes against. You'll set the rules for how AI agents interact with the UI, ensuring quality scales at the pace of a rapidly growing company. This is a rare seat for someone who wants to shape the how, not just the what.
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.
