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.
