Staff C++ Engineer

Staff C++ Engineer
Belfast (Hybrid)

My client is a serious engineering business working close to the metal - this is genuine low-level systems work for someone who enjoys understanding what's happening beneath the abstractions. This is a Staff-level role at the top of the engineering team, combining deep technical contribution with the influence to shape direction.

This is a hands‑on role for someone who wants to own meaningful parts of a complex system, make architectural calls and raise the bar for the engineers around them.

What you'll be doing

• Designing and building high-performance, low-level systems in modern C++
• Owning architecture and technical direction across complex, performance-critical components
• Working close to the hardware - memory management, concurrency, optimisation and systems-level problem solving
• Setting engineering standards and best practices across the team
• Mentoring and elevating the engineers around you
• Contributing to technical strategy at a senior level

What they're looking for

• Deep, production-grade C++ expertise, with a strong grasp of modern C++ standards
• Solid experience with low-level and systems-level engineering - memory, concurrency, performance optimisation
• A track record of owning complex technical work end to end
• Strong fundamentals in data structures, algorithms and computer systems
• Experience operating at a senior or staff level, with the ability to lead through influence
• Someone who genuinely enjoys working close to the metal

This is a role for someone who wants to do serious, technically demanding low-level engineering and have real ownership over how it's built.
