Senior C​/C++ Linux Developer

Role:
Senior C/C++ Linux Developer.

Location:
Toronto, ON (Onsite).

Duration:
Long Term Contract.

Job Overview
Build and maintain high-performance, low-latency applications powering Risk, Finance, Compliance, and Financial Crime systems at RBC scale. Own technical design through production deployment of mission-critical C/C++ components integrated with enterprise messaging (MQ/Kafka).

Core Technical Ownership
Messaging & Integration

• IBM MQ:
  Queue management, XA transactions, triggered processing
• Kafka:
  Multi-partition consumers, exactly-once semantics, schema registry
• Integration: C/C++ clients consuming Java/Scala services

Systems Programming

• C/C++:
  Memory management, multithreading (pthreads), STL optimization
• Linux:
  Kernel tuning, systemd services, strace/gdb profiling
• Performance:
  Low-latency design (< 10ms p99), lock-free patterns
• Vendor Products:
  Reverse engineering, API extension, debugging

Development Excellence

• OOD: SOLID principles, RAII, CRTP, policy-based design
• Functional:
  Lambdas, std::function, immutable transformations
• Testing: GTest, Google Mock, property-based testing
• CI/CD:
  Jenkins pipelines, Sonar Qube, Docker containerization

Day-to-Day Impact

• Production Incident Resolution:
  Root cause analysis of MQ/Kafka outages affecting millions of transactions
• Legacy Modernization:
  Refactor 20-year-old C codebases while maintaining 99.99% uptime
• Performance Engineering:
  Reduce trading system latency from 150ms 8ms p99
• Agile Delivery: 2-week sprints delivering C++ microservices to production

Required Expertise (Must Demonstrate Production)

• 5+ years C/C++17 systems programming (multithreading, memory pools)
• 3+ years Linux production (systemd, kernel tuning, perf profiling)
• 2+ years messaging (IBM MQ queue depth management + Kafka Streams)
• Legacy analysis (COBOL/C migration patterns, vendor product extension)
• Java/Scala integration (JNI bridges, REST/gRPC interop)
• SOLID + functional programming (modern C++ paradigms)
