The role
The founding senior engineer is in the ultimate cross-sectional position, and will be involved in solving tough algorithmic problems, managing the entire tech stack, and building products end-to-end.
This will include building highly performant desktop applications (both the frontend and backend), as well as doing work on algorithmic development, and working closely with others on the team, especially AI engineers.
The role the founding engineer plays is limited only by their ability and ambition. The successful candidate must be an especially fast learner and problem solver with the ability to recognise and solve (or learn to solve) almost any problem that may arise.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
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.
