About the role

We are looking for a C++ Software Developer to join Bitdefender's Endpoint Security Windows team. You will work on the Windows endpoint security product, developing and maintaining components that run on millions of endpoints and integrate multiple security technologies into a single product. The role involves both developing new functionality and working with an established, complex codebase where performance, reliability, security, and compatibility are essential. You will have the opportunity to work close to the Windows operating system, investigate complex real-world problems, and collaborate with multiple engineering teams responsible for different security technologies.

What you'll do

  • Design, develop, maintain, and improve C++ components running on Windows.
  • Integrate security technologies and components developed by other Bitdefender teams into the Endpoint Security product.
  • Design and implement Windows services, processes, libraries, and supporting components.
  • Work with Windows APIs and operating-system-level functionality.
  • Investigate and resolve complex issues involving performance, memory, concurrency, networking, operating system behavior, and interactions between product components.
  • Debug problems using tools such as Visual Studio, WinDbg, Windows Performance Analyzer (WPA), ETW, and other Windows diagnostic tools.
  • Analyze crashes, hangs, memory corruption, performance regressions, and other problems occurring in production environments.
  • Design reliable solutions involving multithreading, synchronization and inter-process communication.
  • Participate in technical and architectural discussions and propose improvements to existing components.
  • Write clean, maintainable, testable, and efficient code.
  • Perform code reviews and contribute to improving engineering practices within the team.
  • Collaborate with QA, product management, and other engineering teams throughout the development lifecycle.
  • Continuously learn about new Windows capabilities, security technologies, development tools, and programming languages.

What we're looking for

  • Strong knowledge of C++ and experience developing production software.
  • Good knowledge of modern C++ and the C++ Standard Library.
  • Good understanding of: object-oriented programming and software design; data structures and algorithms; memory management; multithreading; synchronization primitives; inter-process communication.
  • Experience developing software for Microsoft Windows.
  • Good knowledge of the Windows API (Win32) and Windows system programming concepts.
  • Good understanding of operating-system concepts such as: processes and threads; virtual memory; files and I/O; services; synchronization; CPU and storage behavior.
  • Strong debugging and troubleshooting skills.
  • Ability to investigate complex problems methodically, including problems that cannot be easily reproduced locally.
  • Basic understanding of computer networking and common network protocols.
  • Good software architecture and design skills.
  • Good written and verbal communication skills.
  • Ability to collaborate effectively with engineers from different teams.

Nice to have

Experience in one or more of the following areas is a plus:

  • Windows internals.
  • WinDbg and crash dump analysis.
  • ETW, Windows Performance Recorder and Windows Performance Analyzer.
  • Windows kernel or driver development.
  • Network programming and Windows networking APIs.
  • Cybersecurity or endpoint security products.
  • Windows Firewall / Windows Filtering Platform.
  • TLS, certificates and cryptography.
  • Software deployment, installation and update technologies.
  • Performance profiling and optimization.
  • Python or PowerShell scripting.
  • Rust.
  • Large-scale software products with long-lived codebases and strong backward-compatibility requirements.

What you can expect

You will join a team working on technically challenging problems at the intersection of C++, Windows internals and cybersecurity. The role provides opportunities to work on both high-level product architecture and low-level technical problems, from designing new components to analyzing crashes, performance problems and operating-system interactions occurring on real customer machines. You will collaborate with experienced engineers across Bitdefender and contribute directly to the reliability, performance and security of the Endpoint Security product.
