C++ Developer / Test Engineer (GoogleTest / G-Test)

About the Role

We are seeking a highly skilled C++ Developer / Test Engineer with strong expertise in unit testing, debugging, and software quality engineering. The ideal candidate will have hands-on experience developing and executing automated test cases using GoogleTest (G-Test) and validating enterprise-grade C++ applications.

This role requires strong implementation capability, debugging maturity, and a deep understanding of software testing methodologies to improve application stability, code quality, and production readiness.

Key Responsibilities

• Design, develop, and execute unit test cases using GoogleTest (G-Test).
• Improve code coverage and ensure application reliability.
• Perform debugging, root cause analysis, and issue resolution.
• Validate server-side customizations and application behavior.
• Analyze logs and troubleshoot production and development issues.
• Collaborate with development teams to resolve defects and improve software quality.
• Support CI/CD pipelines and automation initiatives.
• Contribute to software quality, maintainability, and testing best practices.

Required Qualifications

• 3–6 years of experience in C++ development and/or testing.
• Strong hands-on experience with GoogleTest (G-Test) or similar unit testing frameworks.
• Excellent understanding of Object-Oriented Programming (OOP).
• Strong knowledge of STL, pointers, memory management, and data structures.
• Experience in debugging, log analysis, and root cause investigation.
• Familiarity with Git, Jenkins, and CI/CD workflows.
• Ability to work independently on real-world implementation and testing challenges.
• Comfortable working in a hybrid setup from Pune.

Preferred Qualifications

• Experience with Teamcenter customization or PLM applications.
• Exposure to enterprise software development environments.
• Knowledge of software quality assurance and automation practices.

What We're Looking For

• Strong practical implementation skills.
• Ownership of testing and debugging activities.
• Experience working on production-grade applications.
• Ability to analyze complex issues and drive resolutions.
• Focus on software quality, reliability, and maintainability.

Evaluation Criteria

Candidates will be assessed on:

• Practical C++ implementation capability.
• GoogleTest framework expertise.
• Debugging and problem-solving skills.
• Understanding of OOP, STL, and memory management.
• Real project ownership and execution depth.
• Code quality and testing best practices.

Key Responsibilities

1. Kernel Lifecycle & Maintenance

Upstream Alignment: Lead the strategy for upgrading enterprise kernels (e.g., migrating from LTS 5.15 to 6.6) while maintaining binary compatibility where required.

Patch Porting: Expertly port functional and performance patches between disparate kernel versions, resolving complex code conflicts and API changes.

CVE Mitigation: Monitor the Linux Kernel Mailing List (LKML) and security advisories to identify and backport CVE patches from upstream to production environments.

2. Deep-Dive Debugging & Stability

Panic Analysis: Act as the final escalation point for Kernel Panics and "Oops" messages. Utilize kdump, crash, and gdb to perform post-mortem analysis of vmcores.

Boot-Time Resolution: Debug critical failures during the early boot process (UEFI handoff, initramfs, and early kernel init) where standard logging is unavailable.

Performance Tuning: Use ebpf, ftrace, and perf to identify bottlenecks in memory management, scheduler latency, or I/O throughput.

3. Driver Development & Hardware Integration

Driver Ownership: Design, develop, or maintain at least one Open Source or Proprietary Device Driver (Network, Storage, GPU, or Character devices).

Hardware Abstraction: Interface directly with hardware registers, managing DMA mappings, and optimizing interrupt handling (MSI-X, Threaded IRQs).

Out-of-Tree Management: Maintain driver compatibility across kernel updates using DKMS or similar frameworks.

4. Infrastructure & Automation

Registry Management: Oversee the distribution of custom kernel builds and modules via GitLab Container/Package Registries.

CI/CD for Kernel: Build automated testing pipelines (Hardware-in-the-loop) to validate kernel stability before enterprise-wide deployment.

Required Technical Skills:

Languages: Mastery of C/C++ Programming (C is preferred)

Kernel Internals: Deep understanding of VFS, Memory Management (MMU/Paging), Process Scheduling, and Networking Stacks.

Debugging Tools: Expert-level use of kprobes, trace-cmd, valgrind, and hardware-level debuggers (JTAG/Serial Console).

Build Systems: Proficiency with Kbuild, Makefiles, and building RPM/Debian packages for kernel distribution.

Security: Hands-on experience with SELinux/AppArmor policy development and kernel hardening (FIPS, KSPP).

• Firmware Design and Development experience on different micro-controllers.
  
• C/C++ programming
  
• Linux Commands Operating System Concepts
  
• board bring up, embedded software, Kernel Build, Yocto
  
• Shell scripting Networking Concepts Openwrt OS Concepts
  
• Must have good Communication and Presentable skills.
  
• Experience on any Wifi, Bluetooth, GSM modules is a plus.
  
• Design, develop, code, test and debug system software.
