About Mitsogo | Hexnode

Mitsogo is a global organization that highly values the contributions of each employee. Our ability to attract top talent is a testament to our commitment to fostering a sense of belonging for everyone. We recognize the rapid evolution of technology and society that impacts our industry, and we prioritize equipping our employees with diverse opportunities and empowering them with a wide range of skills.

Operating in over 100 countries, Hexnode UEM empowers organizations in diverse sectors. Fueling the transformation to a seamless ecosystem of connected tools, Hexnode is revolutionizing the enterprise software and cybersecurity landscape.

Role

We are seeking a Senior Windows Device Driver Engineer for our Windows Kernel Development team to build, debug, and maintain kernel-mode drivers and user-mode components. This role requires strong hands-on expertise in Windows internals and low-level debugging, and is expected to grow into technical leadership—mentoring engineers and owning a component end-to-end—while remaining primarily an individual contributor.

You will work closely with a Windows Kernel Development team based in Chennai, own a driver component or feature area, and collaborate across QA, product, and support to ship production-grade driver code. If you have strong hands-on Windows driver experience and are ready to start taking on technical leadership, we want you on this team.

Responsibilities

• Design, implement, and maintain Windows kernel-mode drivers, user-mode components (e.g., mini-filters, WFP network callouts, WDF function drivers).

• Debug complex, low-level issues such as crash dumps, BSODs, race conditions, and IRQL violations, using tools like WinDbg.

• Own a driver component or feature area end-to-end, from design through shipping and support.

• Build and maintain the user-mode components around your driver, including services, DLLs, and COM interfaces, primarily in C/C++.

• Participate in code reviews, help onboard and mentor less experienced engineers, and contribute to technical design decisions for your team.

• Work with QA/test to ensure driver stability and, where applicable, support certification processes (WHQL/HLK).

• Collaborate with cross-functional teams (product, QA, support) to translate requirements into robust, production-ready driver code.

Required Experience & Expertise

• 5-8 years of professional software engineering experience, with hands-on Windows Systems/Kernel Development.

• Hands-on experience building or maintaining Windows kernel-mode drivers and/or user-mode components (KMDF, WDM, WDF, UMDF, mini-filter, WFP, or similar).

• Strong C and/or C++ skills at a systems level (primary language requirement), with C# as a secondary language (e.g., tooling, services, test harnesses).

• Solid understanding of Windows internals (memory management, process/thread scheduling, IRQL, synchronization).

• Experience with WinDbg or equivalent kernel debugging tools, and comfort reading crash dumps.

• Some early leadership signal: youve owned a module or feature, mentored a teammate, or acted as the de facto technical lead on something.

• Nice-to-have: experience with file-system mini-filters or WFP network drivers, driver signing/WHQL/HLK exposure, user-mode systems experience (Windows services, DLLs, COM), or endpoint security related technologies.

• Bachelors or Masters degree in Computer Science, Information Security, Engineering, or a related discipline.

Hexnode is an Equal Opportunity Employer. We welcome and encourage candidates of all backgrounds, identities, and experiences to apply.
