Investigating and resolving production crashes
Performing deep debugging (call stacks, memory issues, threading)
Optimising multi-threaded, real-time systems
Collaborating with engineers, QA, DevOps, and business users
Mentoring junior developers and raising engineering standards
What we're looking for:
Strong commercial experience in modern C++ (11/14/17)
Background in performance-critical systems
Hands-on experience with debugging and crash analysis
Solid understanding of concurrency, memory management, and optimisation
Comfortable working in fast-paced, production-focused environments
Hybrid working, long-term platform ownership, and genuinely complex engineering challenges.
