Job Title: C++ Technical Architect

Experience Level: 10+ years

Employment Type: Full-Time

Location :- Mumbai / Bangalore

About the Role

We are seeking a highly experienced and self-driven C++ Technical Architect to lead the evolution of a mature, complex legacy product. The ideal candidate will have deep expertise in C++, system-level programming, and performance optimization. This is a critical role that requires strong technical leadership, problem-solving abilities, and a passion for clean, maintainable code and architecture transformation.

Key Responsibilities

- Analyze and understand a large, complex legacy C++ codebase.
- Troubleshoot and resolve deep system-level issues such as memory leaks, heap/stack corruption, race conditions, and performance bottlenecks.
- Lead modernization efforts including code refactoring, partial rewrites, and design improvements, using static code analysis, AI-assisted tools, and manual reviews.
- Drive architectural evolution towards a stateless microservices-based architecture.
- Collaborate with stakeholders to define technical strategy and roadmap alignment.
- Design and implement high-performance, scalable, and maintainable components in C++.
- Perform rigorous performance testing, benchmarking, and tuning across bare metal, virtualized, and containerized environments.
- Ensure code quality and reliability through best practices and tool usage (valgrind, ASan/TSan, perf, gdb, etc.).
- Provide mentorship and technical guidance to development teams.
- Collaborate cross-functionally with QA, DevOps, and Product Management.

Required Skills and Experience

- Expert-level proficiency in C++ (including modern standards up to C++17/20), STL, and low-level system programming.
- Strong understanding of data structures, algorithms, and design patterns.
- Proven experience with debugging and resolving system-level issues on Linux, including memory management, stack/heap analysis, and concurrency bugs.
- In-depth knowledge and hands-on use of Linux performance and debugging tools: gdb, valgrind, perf, strace, lsof, asan/tsan, objdump, etc.
- Familiarity with static code analysis tools, code quality assessment, and GenAI analysis tools for codebase evaluation and refactoring.
- Experience designing and evolving large-scale systems into stateless, microservices-based architectures.
- Strong understanding of deployment environments: bare-metal, VMs, and containers (Docker, Kubernetes).
- Hands-on experience with RDBMS (e.g., PostgreSQL, MySQL) and Object storage systems (e.g., S3-compatible).
- Experience in performance testing and benchmarking frameworks, tools, and methodologies.

Nice to Have

- Familiarity with modern CI/CD pipelines and DevOps practices.
- Exposure to cloud-native technologies and platforms.
- Prior experience working with legacy-to-modernization transformations.
- Knowledge of distributed systems design principles.

Soft Skills

- Strong analytical and problem-solving skills.
- Excellent written and verbal communication.
- Ability to work independently and mentor others.
- Strategic thinking with a pragmatic approach to legacy code challenges.
