C++ Developer – High Frequency Trading (HFT Systems)

Join MARGO in the UK (London) – High Performance Trading Environments

MARGO is a tech-native consultancy delivering elite software engineering expertise to the most demanding financial markets environments.

We operate in latency-critical trading contexts where performance, determinism and predictability are core system requirements. Our consultants work in highly specialised trading environments, designing systems that interact directly with exchanges and market venues under extreme time constraints.

Business Context

You will join a High Frequency Trading / Low Latency Trading environment within one of our partners (investment banks, proprietary trading firms or market makers).

The teams design, build and operate latency-sensitive trading systems directly connected to exchanges, typically deployed in colocated environments.

These systems are characterised by:

Microsecond to sub-microsecond latency constraints
Deterministic and predictable execution paths
Minimal software and network overhead
Direct interaction with market data feeds and order gateways

Role Overview

We are looking for a C++ Software Engineer to work on latency-critical trading infrastructure.

The role is strongly engineering-driven and focuses on speed, predictability and control of execution rather than functional feature delivery.

Depending on the environment, the role may also involve interaction with C# components used outside the ultra-latency-critical execution path.

Key Responsibilities

Core HFT Engineering

Design, develop and optimise ultra-low latency C++ trading components
Work on critical execution paths for market data processing and order routing
Implement lock-free and wait-free algorithms
Optimise memory allocation, cache locality and CPU utilisation
Reduce jitter and tail latency

System-Level & Hardware-Aware Optimisation

Analyse and optimise CPU behaviour (branch prediction, cache misses, NUMA effects)
Work closely with infrastructure and network teams on kernel bypass and user-space networking
Profile systems at instruction-level and hardware-counter granularity

Production Ownership

Ensure correctness, determinism and stability of production trading systems
Participate in production releases and live deployments
Investigate latency regressions and production anomalies
Maintain rigorous operational discipline

Use of C# (Non-Critical Path)

C# may be used outside the latency-critical execution path for:

Monitoring and control tooling
Configuration and orchestration services
Risk guards, limits and kill-switch mechanisms
Real-time dashboards and operational analytics

C# is not used on the execution path and does not replace core C++ expertise.

Technical Environment

Core Technologies

Modern C++ (C++17/20)
Lock-free programming
Custom memory allocators
Zero-copy architectures
Linux (advanced / low-level understanding)
CPU pinning
Huge pages
NUMA architectures
Networking
TCP / UDP market data feeds
Multicast
Kernel bypass technologies (DPDK, Solarflare Onload or equivalent)

Latency & Performance Tooling

CPU profilers and hardware performance counters
Packet capture and latency measurement tools
Exchange simulators and market data replay tools

Required Experience & Skills

Essential

Strong experience in C++ development for performance-critical or low-latency systems
Proven background in HFT or ultra-low latency trading environments
Deep understanding of CPU architecture, caches and memory models
Strong knowledge of concurrency, memory ordering and Linux internals
Experience working close to hardware and network layers
Strong production mindset and sense of ownership

Highly Valued

Exposure to C# in trading, control or monitoring systems
Experience with market data feed handlers or order gateways
Prior exposure to market making or proprietary trading environments
Experience with FPGA-assisted or hybrid architectures

Why Join MARGO

Access to elite HFT and ultra-low latency trading environments
Technically extreme and intellectually demanding engineering assignments
Clear separation between execution-critical and supporting systems
Human-sized consultancy with very high technical standards
Long-term positioning on rare, high-value low-latency engineering skillsets

Important Note

This role is not suitable for candidates with a C#-only background.

Core execution systems are implemented in C++.

Please note - We do not offer visa sponsorship for this position.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
