The Work
Not every C++ job sits this close to a live market.
You’ll be building the software that processes trading activity in real time, systems that must stay reliable under heavy message throughput and respond in microseconds, not milliseconds.
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.
Your work will sit inside a core engineering team responsible for the platform that powers electronic markets across Europe.
You’ll spend your time solving problems like:
- Processing thousands of market events every second
- Designing software that stays stable under extreme load
- Improving latency, performance and system resilience
You won’t be working in isolation either. You’ll collaborate daily with engineers focused on infrastructure, product and quality to ensure every release is stable and production-ready.
And the problems are genuinely technical.
You’ll work on event-driven systems, networking protocols and real-time architectures where small design decisions have a measurable impact on performance.
The engineering team is compact and experienced. You’ll have the freedom to explore solutions, challenge ideas and contribute to architectural discussions — not just implement tickets.

What you’ll need
This environment suits someone who enjoys deep technical problems and systems that must perform under pressure.
You’ll likely bring:
- Strong C++ development experience (modern C++11 or later)
- Experience building or maintaining real-time or event-driven systems
- Solid Linux development experience and understanding of networking (TCP, UDP or multicast)
And you’ll probably recognise some of the following:
- C++, Boost, Python, Git, SQL, messaging systems, distributed architectures.
Exposure to financial markets technology such as FIX or other trading protocols is useful, but not essential if you’ve worked on other high-throughput systems.
What happens next
If this sounds like the kind of engineering environment you enjoy, apply and we’ll arrange a confidential conversation to walk through the systems, architecture and team in more detail.
