Senior C++ Engineer
Are you a software engineer passionate about building high-performance, low-latency systems?
Do you want to leverage your C++ expertise in an exciting, high-impact risk analysis environment where your code processes billions of transactions worldwide?

About the Business
LexisNexis is a data and analytics company with 10,500 colleagues serving customers in more than 150 countries. We're one of the largest information and analytics companies on the planet. We design solutions that help our customers increase productivity, improve decision-making and outcomes, and be more successful.

About our Team
Lexisnexis Risk Solutions, a part of RELX, is a global leader in digital identity intelligence and fraud prevention. Our engineering teams build high-performance systems that process billions of transactions, helping organizations make trusted decisions in real time.

About the Role
As a Senior C++ Engineer, you will play a pivotal role in designing and developing high-performance, low-latency backend systems at the core of our fraud prevention platform. You will leverage your expertise in modern C++, multi-threaded programming, and distributed systems to build and optimise services that process massive volumes of transactions in real time across multiple regions worldwide.
Reporting to an Engineering Manager, this is a full-time role within a high-performing engineering team. This role will be based in Australia (Sydney preferred), with flexibility to work from home.

About the Team
Our team builds and maintains high-throughput, low-latency systems that process massive volumes of transactions in real time. Engineers in this team collaborate closely with data scientists, platform engineers, and product managers to deliver systems that power trusted decisioning at global scale.

You will work with modern C++, NoSQL databases, message queues, and scripting layers, contributing to a platform deployed across multiple data centres — a mixture of on-premises clusters and cloud-based infrastructure — orchestrated via Kubernetes.

Responsibilities

Design and develop high-performance C++ backend services and components
Build and optimise multi-threaded, low-latency systems for real-time transaction processing
Work with NoSQL databases and message queue technologies to handle large-scale data flows
Contribute to scripting and configuration layers that drive system behaviour
Troubleshoot, profile, and improve system performance, scalability, and reliability
Contribute to system architecture, design decisions, and engineering best practices
Review code and mentor junior engineers
Ensure high-quality, maintainable, and testable code through static analysis, sanitizers, and thorough testing

Requirements

Strong proficiency in modern C++
Solid experience with multi-threaded and concurrent programming
Experience with CMake or similar C++ build systems
Strong Linux systems programming skills
Solid understanding of distributed systems and microservices architecture
Experience with NoSQL databases (e.g., Aerospike, Cassandra, or similar)
Experience with message queue technologies (e.g., Kafka, ActiveMQ, or similar)
Proven ability to profile, debug, and tune performance-critical systems
Strong problem-solving and debugging skills
Ability to work in a fast-paced, collaborative environment

Desirable

Working experience with Python
Experience with Lua scripting
Experience with Go
Familiarity with Boost libraries
Familiarity with RPC frameworks (e.g., Thrift, gRPC)
Experience with Kubernetes and Docker

Work in a way that works for you
We promote a healthy work/life balance across the organization, with various flexible and remote working options available to employees.

Working for you
We know that your wellbeing and happiness are key to a long and successful career. These are some of the benefits we are delighted to offer:

Discounted Health plan rate and Optical Assistance
Life assurance and income protection
Option to buy additional Annual Leave days
Employee Assistance Program
