What is a low latency network engineer?

A Low Latency Network Engineer is responsible for designing, optimizing, and maintaining high-performance network infrastructure to minimize latency in data transmission. They work primarily in industries like financial trading, telecommunications, and high-frequency trading (HFT), where microseconds matter. Their role involves configuring network hardware, optimizing protocols, reducing congestion, and utilizing advanced technologies like FPGA, kernel bypass, and RDMA. They also collaborate with software engineers to fine-tune system performance and ensure ultra-fast data processing.

What are some typical challenges a low latency network engineer faces on the job?

Low Latency Network Engineers often face the challenge of continuously reducing network latency while maintaining stability and security. You will frequently analyze and troubleshoot bottlenecks, adapt to rapidly changing technologies, and ensure seamless coordination between hardware and software solutions. Collaborating closely with traders, developers, and systems engineers is common to meet ultra-low-latency requirements. Staying up-to-date with the latest networking advancements and proactively solving technical issues are essential aspects of this dynamic role.

What are the key skills and qualifications needed to thrive as a low latency network engineer?

To excel as a Low Latency Network Engineer, you need deep expertise in network protocols, high-frequency trading environments, network performance optimization, and a relevant degree in computer science, engineering, or a related field. Familiarity with tools such as Wireshark, SolarWinds, FPGA-based accelerators, and certifications like CCNP or CCIE are highly beneficial. Strong problem-solving, attention to detail, and effective communication set exceptional candidates apart. These skills enable engineers to deliver ultra-fast and reliable network solutions crucial to industries like finance, telecommunications, and large-scale data centers.

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.

Locations and Right to work: This role can be based out of our Zurich, London, New York or Hong Kong office. Only candidates who possess the pre-existing right to work in one of the locations above without company sponsorship need apply.
Join G-20 and be a part of a team that is at the forefront of financial markets, driving innovation and excellence in the sector.
