Senior Low Latency Rust Engineer
About the Opportunity
Join a world-leading global investment bank where technology sits at the heart of the business. Every day, the engineering organisation builds and supports mission-critical platforms that power global financial markets, processing enormous volumes of market data and enabling electronic trading across multiple asset classes.
You'll join a specialist engineering team responsible for designing the high-performance frameworks, tooling and infrastructure that underpin low-latency trading systems used across the organisation. This is an opportunity to work on software where microseconds matter, solving some of the most technically demanding challenges in modern distributed systems engineering.
The Role
We're looking for an experienced Senior Low Latency Rust Engineer to join a specialist High Performance Architecture team focused on building reusable frameworks and platform capabilities that enable the next generation of electronic trading applications.
The team operates as an internal centre of engineering excellence, partnering with development teams across multiple trading businesses to modernise applications, improve performance and build highly scalable event-driven platforms.
This is a genuinely hands-on engineering role, with approximately 90% of your time spent writing production code.
You'll develop sophisticated event-driven systems operating with response times measured in 10–100 microseconds, delivering the infrastructure that powers mission-critical algorithmic trading applications.
Essential functions
What You'll Be Working On

Low latency event-sourcing frameworks
Market data replay platforms
Trading simulation and back-testing utilities
High-performance microservices
Algorithmic trading infrastructure
Market data processing systems
Performance profiling and optimisation
Modernisation of mission-critical trading applications
You'll also work closely with engineering teams across the business, helping modernise existing trading platforms while mentoring engineers on low-latency engineering techniques and software design best practices.
Responsibilities
Design and develop ultra-low latency applications using Rust and Java
Build high-performance event-driven microservices
Engineer reusable frameworks supporting electronic trading and algorithmic execution
Develop market data replay and simulation tooling
Optimise applications operating within 10–100 microsecond latency targets
Analyse complex performance bottlenecks across the JVM, Linux and networking stack
Improve scalability, throughput and determinism of distributed trading systems
Collaborate with engineering teams modernising trading applications
Mentor developers on low-latency design and performance engineering
Contribute to architecture, design discussions and engineering standards
