Senior C# Full Stack Engineer

FULLY ONSITE: London

Salary: £100,000 to £130,000

This is an opportunity for a senior engineer to take ownership of complex systems and contribute to the direction of a growing engineering function. You will work on high-impact projects with real-time performance challenges.

The Company

They are an established, technology-led organisation with a strong focus on high-performance systems and data-driven decision making. The engineering team is central to the business, working on a diverse range of projects with significant technical depth. The culture is collaborative, with a strong emphasis on autonomy and ownership.

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.
