Senior Low Latency Rust Engineer - Electronic Trading
Location: London
Working model: Hybrid - max 3 days per week in office
We are assisting with the hire of an experienced low-latency engineer to join a specialist team building frameworks, libraries and performance tooling used across a large global electronic trading environment.
This is not a traditional BAU development role attached to one desk or application. The team works across multiple trading platforms, solving complex performance problems and helping define how latency-sensitive systems should be engineered.
Approximately 90% of the role is hands-on coding, with a major focus on Rust alongside modern Java.
What you’ll work on
- Low-latency Rust and Java frameworks
- Event-sourced systems operating in the 10-100 microsecond range
- Market-data replay, backtesting and simulation tooling
- High-performance market-data processing
- Linux, kernel and systems-level performance optimisation
- TCP/IP networking and kernel-bypass technologies
- Performance profiling, benchmarking and latency reduction
- Frameworks and tooling used across 100+ technology teams
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 we’re looking for
You’ll ideally come from a background in algorithmic trading, electronic trading, market data or another genuinely latency-sensitive environment. Financial Services background is not crucial.
Relevant experience could include:
- Rust, modern Java or C++
- Low-latency / high-throughput systems
- Algorithmic or electronic trading
- Market-data technologies
- Linux internals and kernel behaviour
- TCP/IP networking
- Solarflare / OpenOnload or similar kernel-bypass technologies
- KDB or other time-series databases
- Performance tuning and optimisation
Get help with your application
Your very own career expert that helps elevate your application to the next level.
You do not need to match every technology listed. The key requirement is genuine depth in high-performance systems engineering and an ability to understand latency across the full stack.
Why consider it?
The standout here is the combination of:
- Rust + microsecond-level performance engineering + large-scale production electronic trading.
You’ll remain deeply hands-on while working on engineering problems that sit underneath multiple trading platforms, rather than maintaining a single application.
Compensation: Highly competitive
