We’re working with a client delivering large-scale business-critical software, and they’re looking for a Senior C++ Engineer to play a key role in stabilising and evolving a complex platform.

This role is ideal for engineers who enjoy getting deep into systems, understanding how things really work, and helping guide long-term technical direction.

What you’ll be doing

• Debugging and resolving issues across a multi-layered, multi-language system
• Working hands-on with C++ at the core of the platform
• Building a strong understanding of system internals and behaviour
• Identifying areas of technical debt, risk, and improvement
• Supporting decisions around modernisation and future architecture
• Contributing to build, release, and deployment workflows
• Working across integrations with external systems and services

What we’re looking for

• Strong C++ engineering experience in complex or long-lived systems
• Experience working across mixed technology stacks (e.g. C++, C#, SQL, web technologies)
• Ability to navigate and reason about large, unfamiliar codebases
• Strong debugging and problem-solving skills
• Comfortable working with low documentation and high complexity
• Solid understanding of software engineering fundamentals and system design

Nice to have:

• Experience with Windows-based systems or legacy architectures
• Exposure to .NET, databases, or integration-heavy environments
• Background in modernisation or migration of legacy platformsWhy this role stands out

• Work on a deep, technically challenging system with real-world impact
• Opportunity to influence how a platform evolves over time
• Suited to engineers who enjoy solving hard problems, not just building new features

If you’re a C++ engineer who enjoys complexity and wants to make a tangible impact, I’d be keen to speak.
