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
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You Will Do
- Develop and maintain the core Borderless platform using TypeScript, React (NextJS), and Node.js to serve candidates, businesses, and internal teams.
- Design and scale complex PostgreSQL data models to ensure high performance and extensibility as the product expands into new global jurisdictions.
- Integrate advanced LLM and AI capabilities to automate document classification and extraction, significantly reducing manual overhead for international visa applicants and employers.
The ideal candidate
- Possesses 4–7+ years of professional engineering experience with a deep mastery of the full-stack: TypeScript, React, Node.js, and PostgreSQL.
- Demonstrates a proven track record of shipping fast and owning features end-to-end within the fast-paced, high-ambiguity environment of an early-stage startup.
- Displays strong architectural thinking, especially regarding asynchronous workloads via AWS SQS and the tradeoffs between speed-to-market and long-term technical stability.
