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
- Design, build, and operate highly available, mission-critical software for live aviation environments using Rust and Flutter.
- Collaborate with product stakeholders to develop distributed and federated architectures that support complex, real-world operational workflows.
- Improve reliability, performance, and user experience across the Opfyx AIR platform while helping to shape engineering practices as the team scales.
The ideal candidate
- A self-starter with strong technical instincts across the full stack and the ability to own projects end-to-end in a fast-moving environment.
- Experience or a strong willingness to master a high-performance stack including Rust, Flutter/Dart, gRPC, Arrow, and Postgres.
- A user-first mindset with the technical caliber to build scalable systems for an industry that moves billions of people annually.

We never post fake jobs
This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.
Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.
We appreciate this can make them look a bit suspect, but there isn't much we can do about it.
Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
