About Dex
Dex is an AI recruiter agent that helps you run your job search. Tell Dex your stack, seniority, and what you want to build. We will manage your applications and surface other opportunities that are a fit.
The Role
This company is building the definitive API for global tax automation. Think complex financial systems, real-time compliance, and a product suite that plugs directly into enterprise operations. They're backed by leading VCs, have significant ARR, and are growing rapidly, tackling a problem few others can solve at this scale.
You'll join a lean engineering team that owns problems end-to-end, not just features. This is a principal-level seat: you'll co-own the roadmap with product, drive architecture, and operate what you build in production. This isn't a ticket-taker role; it's about setting the technical bar and shipping fast, continuously, and iteratively across the full product lifecycle.
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
