Core Technical Skills Required

Debugging Expertise in C++ (Linux environment):
- Strong hands-on experience with GDB for debugging production issues.
- Ability to perform root cause analysis beyond surface-level fixes.
Code Ownership:
- Confidence in understanding and explaining code flow, including AI-generated code.
- Accountability for resolving production issues independently.
Efficient Debugging Practices:
Capability to reproduce bugs quickly by isolating problematic items instead of running full workloads.

Code Quality & Testing

Unit Testing & Coverage:
- Writing comprehensive unit test cases for all code changes.
- Ensuring adequate code coverage before delivery.
Vulnerability Management:
- Familiarity with SonarQube and third-party vulnerability scanners.
- Responsibility for resolving flagged issues before delivery.
Quality Assurance:
Ensuring code does not increase vulnerability statistics monitored by leadership.

Business & Domain Understanding

Ability to grasp complex business logic and criticality of systems.
Awareness of cascading impacts in pipelines (PAG) and downstream applications.
Willingness to engage in knowledge transfer (KT) sessions to build domain expertise.

Performance & Resource Management

Awareness of CPU, memory, and IO usage in production systems.
Proficiency in multi-threading and safe use of pointers (including smart pointers).
Strong understanding of data structures and algorithms, with the ability to select the most efficient option for the task.

Additional C++ Concepts to Prioritize

Memory Management:
- Deep understanding of manual memory handling, smart pointers, RAII (Resource Acquisition Is Initialization).
- Ability to detect and resolve memory leaks and dangling pointers.
Object-Oriented Programming (OOP):
- Strong grasp of inheritance, polymorphism, encapsulation, and abstraction.
- Experience with virtual functions, pure virtual classes, and interfaces.
Templates & Generic Programming:
- Proficiency in function templates, class templates, STL containers, and iterators.
- Understanding of template specialization and type safety.
Concurrency & Synchronization:
- Experience with mutexes, locks, condition variables, atomic operations, and thread-safe design.
Exception Handling & Error Management:
- Writing robust code with proper try-catch blocks, custom exceptions, and fail-safe mechanisms.
Modern C++ (C++11/14/17/20):
- Familiarity with lambda expressions, auto keyword, move semantics, constexpr, smart pointers, and ranges.
Standard Template Library (STL):
- Strong command over vectors, maps, sets, queues, stacks, priority queues, unordered containers.
- Ability to choose the right container/algorithm for performance optimization.
Design Patterns in C++:
- Practical knowledge of Singleton, Factory, Observer, Strategy, and Adapter patterns.
File Handling & I/O Streams:
Experience with fstream, ifstream, ofstream, and efficient handling of large datasets.

Database Skills

Basic proficiency in SQL for interacting with Oracle and other data sources.
Ability to write and run queries for data processing (no advanced optimization required).
