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
- Manage end-to-end voice library operations, including posting job ads for voice actors, managing professional engagements, and maintaining strict quality timelines.
- Execute complex voice production workflows, specifically focusing on the creation and rigorous quality evaluation of synthetic voices through specialized annotation.
- Support core research and analysis objectives within the voice domain, tackling ad-hoc operational tasks that require high flexibility and reliability.
The ideal candidate
- Strong project management instincts with the ability to juggle multiple workstreams and high-throughput operational tasks without letting details slip through the cracks.
- Technical fluency including a solid understanding of how APIs work, practical experience with LLMs, and basic proficiency in Python or SQL.
- A research-driven and curious mindset, comfortable digging into data and using AI coding assistants like Cursor or Claude to rapidly execute high-quality results.

We never post fake jobs

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
