- Work hands-on with.NET and C#, with a strong backend focus
- Contribute across the wider technology stack, including JavaScript, TypeScript, and Node.js
- Take ownership of technical decisions and project outcomes
- Work with modern DevOps, CI/CD, and Terraform practices
- Contribute to architecture and technical direction
- Lead, mentor, and support other engineers
- Work directly with clients and communicate technical concepts clearly
- Challenge existing approaches and identify opportunities for technical improvement
- Adapt quickly to different client environments, technologies, and business challenges
- Maintain strong engineering standards around testing, quality, and delivery
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.
