Senior C++ Developer

We are looking for a Software Engineer (C++) to join a high-stakes team supporting the GPU infrastructure of a global Tier-1 Tech Giant. If you are a systems-level expert who thrives on the intersection of hardware and software, this is the role for you. You will be the primary guardian of core GPU libraries (cuDNN, NCCL) that serve as the bedrock for large-scale Machine Learning and AI workloads. Your mission is to ensure that cutting-edge GPU architectures are seamlessly integrated and maintain extreme stability across massive hardware fleets, from legacy systems to the latest generations.

Responsibilities:

• Library Integration: Own the end-to-end update lifecycle for critical GPU libraries, managing internal versioning, user migration, and alignment with open-source builds.

• Triage & Deep Debugging: Act as a technical detective to identify, investigate, and debug performance regressions and functional bugs; create minimal reproducers for escalation to hardware vendors or internal core teams.

• Build & Infrastructure Maintenance: Manage complex build/linking issues using large-scale build tools and maintain custom patches to ensure seamless integration.

• Validation & Benchmarking: Rigorously verify new library versions against extensive benchmarking suites and coordinate with high-profile internal partners (e.g., Autonomous Driving units) to validate siloed codebases.

• Automation & Evolution: Proactively improve regression benchmarking suites and develop automation tooling to reduce manual effort in library rollouts.

• Technical Documentation: Maintain meticulous records of investigations and keep integration playbooks updated to ensure operational excellence.

Min requirements:

• C++ Proficiency: Strong ability to read, navigate, and debug complex, large-scale C++ codebases.

• Linux Systems Programming: Deep understanding of compilation, dynamic/static linking, ELF binaries, and shared library management.

• Systems Environments: Proficiency with Linux CLI and advanced Bash scripting for infrastructure automation.

• Analytical Depth: Proven track record of triaging ambiguous technical issues and conducting root-cause analysis (RCA).

• Communication: Clear and concise written English (B2+), essential for documenting complex technical bug reports and coordinating with cross-functional global teams.

  
  

Would be a plus:

• Build Systems Mastery: Familiarity with large-scale build tools like Bazel, Blaze, or CMake.

• GPU Ecosystem: Prior exposure to CUDA, cuDNN, or NCCL architectures is highly advantageous.

• Hardware Awareness: Experience managing software compatibility and performance across multiple hardware generations.

• Tooling: Experience with internal data monitoring and bug-tracking systems in a distributed engineering environment.

We offer:

• Opportunity to work on bleeding-edge projects

• Work with a highly motivated and dedicated team

• Competitive salary

• Flexible schedule

• Benefits package - medical insurance, sports

• Corporate social events

• Professional development opportunities

• Well-equipped office
