We are working with a highly technical, fast-growing engineering team building latency-critical, high-throughput systems in a competitive and fast-moving environment. This is a greenfield opportunity within a small, elite team where engineers take full ownership of systems from design through to production.
The Role
You will design, build, and optimise high-performance systems where efficiency, scalability, and reliability are critical. The work is deeply technical and spans the full stack, from low-level systems and networking through to algorithmic performance and optimisation.
This is an environment where strong reasoning and problem-solving ability are just as important as systems experience. You will be expected to tackle ambiguous problems, make architectural decisions, and iterate quickly.
Key Responsibilities
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.

No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
- Design and develop high-performance, low-latency systems in C++ or Rust
- Optimise systems for throughput, latency, and scalability
- Work across the full lifecycle: architecture, implementation, testing, and production deployment
- Analyse and improve system performance through profiling and benchmarking
- Solve complex, non-obvious technical problems in a fast-paced environment
- Collaborate in a small, high-calibre team with significant ownership and impact
Requirements
- 3+ years' experience building high-performance production systems
- Strong proficiency in C++ or Rust (or willingness to transition to Rust)
- Deep understanding of systems concepts (memory, concurrency, networking, hardware interaction)
- Proven track record working on latency-sensitive or high-throughput systems
- Strong problem-solving ability and capacity to reason through complex, novel scenarios
- High ownership mindset with the ability to operate in an ambiguous, fast-changing environment
