Our client is a highly technical team building a greenfield, performance-critical systems platform from first principles. This is a senior-level role for engineers who have deep experience designing and optimising latency-sensitive, high-throughput production systems and enjoy operating close to the metal.

The environment is fast-moving and adversarial, with a heavy emphasis on correctness, performance, and clear engineering thinking. Engineers are expected to take ownership of substantial parts of the system end-to-end.

What you'll be working on:

• Designing and building ultra-high-performance systems where latency and throughput matter
• Optimising software with a strong understanding of hardware interaction
• Owning critical components across the full lifecycle: design, implementation, optimisation, and production
• Solving novel, non-obvious systems problems in a greenfield environment
• Working in a setting with real ambiguity and technical autonomy

What they're looking for:

• 5+ years' experience building and optimising high-performance production systems
• Strong background in systems engineering, not general application development
• Experience with low-latency, high-throughput, or performance-critical software
• Proficiency in Rust, or strong C/C++ experience with willingness to switch
• Sharp problem-solving ability and comfort reasoning through complex, unstructured problems

Backgrounds that tend to fit well:

• Engineers from top HFT, trading, or market-making firms
• Engineers from large-scale infrastructure teams at top technology companies
• PhDs or candidates with evidence of deep technical work (research, simulations, compilers, systems)
• Competitive programmers or engineers with substantial low-level side projects

Why this role:

• Greenfield build with meaningful technical ownership
• Work on genuinely hard performance-driven systems problems
• Small, highly technical team with high engineering standards
• Higher upside: Base salary + guaranteed cash bonus + equity

If you're driven by deep systems work, performance optimisation, and building critical infrastructure from scratch, this is a rare opportunity to do so.
