• Infrastructure as Code: Leverage Terraform and Ansible to deploy across both public and private cloud environments.

What We’re Looking For

• Distributed Systems Expert: 5+ years of experience operating mid-to-large scale systems on Linux (Debian/Ubuntu)-whether on VMs or bare metal.
• The “S” in SRE: 2+ years of development experience with Ruby, Go, Python, or Scala. You prefer building tools to manual toil.
• Observability Specialist: Direct experience with Prometheus/Thanos/Cortex, ELK (Elasticsearch, Logstash, Kibana), Kafka, and Grafana.
• Automation Mindset: Strong proficiency in Terraform, Ansible, and Consul for infrastructure orchestration.
• Problem Solver: You are comfortable diving into unfamiliar codebases and have a deep understanding of software engineering best practices.

C++ Software Developer, Risk Technology £180,000 to £200,000 Join a specialist engineering team responsible for the technology that underpins a global trading risk platform. This environment sits at the intersection of quantitative research, front office trading, and high-performance engineering, where systems must process enormous volumes of market and trade data while maintaining absolute accuracy of risk calculations across multiple asset classes. The platform ingests trades in real time, tracks positions across portfolios, calculates PnL and exposures, and distributes risk metrics across internal systems used by trading and portfolio management teams. We are looking for a C++ engineer who understands the technology challenges associated with financial risk systems. You will be working on software that models complex financial instruments and asset classes, ensuring that risk calculations remain consistent, deterministic, and performant as trading activity and data volumes increase. Engineers here regularly deal with issues such as market data ingestion, pricing model integration, portfolio aggregation, and the propagation of risk metrics across distributed systems used by the front office. The architecture is evolving toward a service-oriented model designed to support large scale distributed compute across a Linux estate. You will help build components that process high frequency data flows, maintain state across complex portfolios, and deliver reliable risk analytics under strict latency constraints. This is a role for engineers who enjoy understanding both the technical and financial dimensions of a system, translating trading concepts into efficient and maintainable software. What you bring • Strong C++ development experience within Linux environments • Prior experience building systems in financial services, ideally within trading or risk platforms • Exposure to financial asset classes such as equities, derivatives, FX, or fixed income and an understanding of how risk is calculated across them • Deep knowledge of algorithms, memory management, multithreading and performance optimisation • Experience working with large scale distributed systems and high volume market or trade data • Familiarity with messaging technologies such as Kafka, AMPS or QPID • Python or bash for tooling and automation, with exposure to Q or KDB considered valuable If you enjoy solving challenging engineering problems at the heart of trading technology and want to build systems that directly support risk and portfolio management across complex financial instruments, Ncounter would welcome a conversation.

We have a current opportunity for a Rust Engineer on a permanent basis. The position will be based in London. For further information about this position please apply.

The Opportunity

Most engineers spend their careers a long way from systems that actually matter. ETrading, you will build the infrastructure that sits between our traders and the market - execution paths, data pipelines, and observability tooling that power trillions in annual notional volume. When a system performs at 3am under peak load, you will be one of the reasons why. This is a rare opportunity to apply Rust in a domain where performance directly changes outcomes, and where your engineering decisions carry real commercial weight.

Requirements

• 5-10 years software engineering; 3+ years production Rust - ownership, lifetimes, and async model are instincts, not references
• Tokio and the broader async Rust ecosystem; concurrent, lock-free, and wait-free data structures in live systems
• Low-latency system design; hot path optimisation, benchmarking, and hardware-level profiling - cache topology, NUMA effects, allocator behaviour
• Custom allocator design, unsafe code review, and rigorous reasoning about memory safety at system boundaries
• High-performance network programming: TCP/UDP, zero-copy I/O, kernel bypass awareness (DPDK, io_uring)
• Distributed messaging and event streaming: Kafka, NATS, or equivalent; ordering guarantees, exactly-once semantics, consumer group management
• Production observability: metrics (Prometheus/OpenTelemetry), distributed tracing, structured logging, and alert design
• CI/CD pipeline design including benchmarking gates, automated performance regression detection, and reproducible builds
• TDD as a design discipline - property-based testing, integration tests, chaos and fault injection experience
• Ability to lead architecture design reviews, author ADRs, and elevate Rust engineering standards across a team
• Cloud infrastructure - Azure preferred, AWS considered; IAM, managed services, automated and auditable deployment pipelines, secrets management

Nice to Have

• Front office trading environment (any asset class) - execution systems, market data infrastructure, or low-latency pricing engines
• FIX protocol, OMS/EMS connectivity, or direct exchange co-location experience
• SIMD, vectorisation, or GPU offloading for numerical workloads; eBPF for observability or network instrumentation
• Open-source Rust contributions, published crates, or ring-buffer/LMAX Disruptor pattern experience

What We’re Looking For

You find the bottleneck before anyone reports it, understand it at the hardware level, and instrument the fix so the next problem surfaces in seconds. You write Rust other engineers learn from and care deeply whether a system is correct - not because a spec says so, but because you know what happens when it isn’t.
