What is a low latency engineer?

A Low Latency Engineer is a specialized software engineer who designs, develops, and optimizes systems to achieve minimal delay, or 'latency,' particularly in environments like high-frequency trading, telecommunications, and real-time data processing. Their work focuses on maximizing the speed of data transmission and processing by fine-tuning software, hardware, and networking components. These engineers use techniques such as algorithm optimization, efficient memory management, and low-level programming to reduce the time it takes for data to travel from source to destination. Their expertise is critical in industries where even microseconds can make a significant difference in performance and outcomes.

What are some common challenges faced by low latency engineers when optimizing trading systems?

Low Latency Engineers often encounter challenges such as minimizing network and hardware delays, efficiently handling large volumes of real-time data, and ensuring system stability under extremely tight time constraints. Achieving microsecond-level responsiveness requires deep knowledge of system architecture, hardware tuning, and specialized programming techniques. The work environment is typically fast-paced and collaborative, with engineers working closely with traders, network specialists, and software developers to implement and test performance improvements.

What are the key skills and qualifications needed to thrive as a low latency engineer, and why are they important?

To thrive as a Low Latency Engineer, you need strong proficiency in C/C++ programming, computer science fundamentals, and experience in high-performance distributed systems, often supported by a degree in computer science or related fields. Familiarity with network protocols, Linux systems, performance profiling tools, and sometimes FPGA or hardware acceleration is typically required. Exceptional problem-solving skills, attention to detail, and the ability to work effectively under pressure make candidates stand out in this role. These skills are crucial because low latency environments demand rapid, reliable solutions that directly impact trading speed, competitiveness, and system stability.

What is the difference between Low Latency Engineer vs Network Engineer?

AspectLow Latency EngineerNetwork Engineer
CredentialsBachelor's in Computer Science, Networking, or related fields; certifications like Cisco CCNA, CCNPBachelor's in Computer Science, Networking, or related fields; certifications like Cisco CCNA, CCNP
Work EnvironmentFinancial trading firms, gaming, telecommunications, data centersInternet service providers, corporate networks, data centers
Industry UsageHigh-frequency trading, real-time applicationsNetwork infrastructure, enterprise connectivity
Search & Comparison IntentFocus on low latency, real-time performanceFocus on network setup, maintenance, and optimization

While both roles require networking knowledge and certifications, Low Latency Engineers specialize in optimizing systems for minimal delay in high-frequency environments like trading or gaming. Network Engineers focus on designing, implementing, and maintaining network infrastructure across various industries. The key difference lies in the emphasis on latency reduction versus general network management.

Job description

About G20 Group
G-20 Group is a cross-asset trading firm headquartered in Switzerland, trading delta-one and derivatives markets globally. We combine startup agility with institutional-grade experience in proprietary trading, technology, and quantitative finance.
Role Overview
We are hiring for a Low Latency Market Making Engineer to design, build, and continuously optimize the systems responsible for quote generation and order execution within microsecond-level latency tolerances. This role sits combines deep knowledge of software engineering, hardware, and market microstructure, and requires close collaboration with traders and quantitative researchers to translate strategy requirements into production systems capable of achieving favorable queue position across trading venues.
Responsibilities
  • Design, build, and maintain ultra-low-latency market making systems, including order entry, market data processing, risk controls, and quote and order management functionality
  • Continuously profile and optimize the tick-to-trade path, from network interface through kernel to application, with close attention to CPU cache behavior, memory layout, branch prediction, and lock-free data structures
  • Collaborate with hardware engineers, or develop FPGA logic directly depending on background, to minimize latency in critical-path processing
  • Own exchange connectivity, including implementation and maintenance of FIX, ITCH/OUCH, or proprietary binary protocols for order entry and market data feeds
  • Partner with traders and quantitative researchers to implement and calibrate quoting logic, risk controls, and inventory management in production environments
  • Build and maintain simulation, backtesting, and replay infrastructure to validate strategy and system changes prior to live deployment
  • Monitor live trading systems, diagnose latency regressions and operational anomalies in real time, and lead root-cause resolution efforts
  • Contribute to capacity planning and infrastructure decisions relating to co-location, network topology, and hardware upgrades
  • Uphold rigorous engineering standards, including code review, testing, deployment safety, and change management practices appropriate for systems executing live capital.

Requirements
  • Currently pursuing or recently completed a degree in Computer Science, Engineering, Mathematics, Data Science, Economics, Business, or a related field, top-tier university preferred
  • Strong proficiency in C++ (modern C++17/20 preferred), with the ability to reason about assembly output and compiler behavior
  • Thorough understanding of computer architecture, including CPU caches, NUMA, memory ordering, and kernel bypass networking technologies (e.g., Solarflare/OpenOnload, DPDK, or comparable solutions)
  • Experience with low-latency networking and associated protocols (TCP/UDP internals, multicast, kernel bypass) as well as exchange connectivity protocols such as FIX, ITCH, or OUCH
  • Solid understanding of Linux internals, including scheduling, interrupt handling, NUMA pinning, and huge pages, with demonstrated experience tuning production systems at the operating system level
  • Working knowledge of market microstructure, including order books, matching engine behavior, queue position, adverse selection, and inventory risk management practices employed by market makers
  • Experience with FPGA development (Verilog/VHDL) is advantageous, though not a strict requirement for all candidates
  • Demonstrated experience working on systems where microsecond- or nanosecond-level performance was critical, such as high-frequency trading, market making, exchange technology, or comparable latency-sensitive domains (telecommunications, high-performance computing, real-time systems)
  • Strong debugging and profiling capabilities using tools such as perf, VTune, or custom tracing and timestamping infrastructure
  • Strong communication skills and the ability to collaborate effectively with trading personnel under time-sensitive conditions during market hours.

Preferred / Desirable Experience
  • Experience building or tuning matching engines or exchange-side systems
  • Exposure to FPGA-based trading systems or programmable networking hardware (e.g., Solarflare, Exablaze, Arista MetaWatch)
  • Prior experience at a market making firm, high-frequency trading firm, or exchange technology vendor.
