Senior Software Engineer, Native Applications and Networking at Jobgether – India

This position is posted by Jobgether on behalf of a partner company. We are currently looking for a Senior Software Engineer, Native Applications and Networking in India.

This role is focused on building and owning deeply technical, system-level software that powers secure, high-performance native applications across Windows and macOS. You will operate at the intersection of operating system internals, networking protocols, and cross-platform engineering, shaping the reliability and security of mission-critical components. The position involves designing and maintaining low-level system integrations, high-performance networking engines, and secure communication layers that underpin complex security-focused products. You will work in a highly technical, remote-first environment alongside engineers, security specialists, and product teams. This is a hands-on engineering role with strong architectural ownership, where your decisions directly influence system stability, performance, and security. You will also contribute to defining long-term technical direction for native platforms in a fast-evolving product ecosystem.

• Architect and own native system-level components across Windows and macOS, including system extensions and filtering frameworks.
• Lead development and optimization of a high-performance Go-based networking engine integrated with OS-level system hooks.
• Design and implement secure inter-process communication (IPC) mechanisms between system services and user-space applications.
• Ensure stability and resilience of native daemons, including handling OS-level challenges such as sleep/wake cycles, DNS conflicts, and network disruptions.
• Optimize performance across packet processing paths, memory usage, and CPU efficiency to ensure minimal system impact.
• Maintain high security standards across all native code, including memory safety, concurrency control, and cryptographic integrity.
• Own release processes for native applications, including code signing, notarization, and platform-specific compliance requirements.
• Collaborate with product, security, and engineering teams to translate requirements into scalable system-level architecture.
• Mentor engineers and provide expertise in systems programming, native application design, and performance optimization.

• Strong professional experience in system-level or native application development on Windows and/or macOS.
• Proficiency in Go, Swift, and C++ or C#, with experience in polyglot system environments.
• Deep expertise in networking protocols including TCP/IP, DNS, TLS, and packet-level operations.
• Hands-on experience with macOS NetworkExtension framework and/or Windows Filtering Platform (WFP).
• Strong understanding of OS internals, including process management, memory handling, and system services.
• Experience with debugging and profiling tools such as Xcode Instruments, Windows Performance Toolkit (WPR/WPA), or equivalent.
• Strong problem-solving mindset with ability to work on complex, low-level engineering challenges.
• Experience working in security-focused, performance-critical, or production-grade distributed systems.
• Strong collaboration and communication skills in cross-functional, remote-first environments.

• Competitive compensation package aligned with senior-level engineering expertise.
• Fully remote-first work environment with flexible working arrangements.
• Opportunity to work on highly complex, system-level engineering challenges at OS and networking layers.
• Strong focus on technical ownership, autonomy, and architectural influence.
• Exposure to cutting-edge security and developer-focused infrastructure technologies.
• Generous leave policies supporting rest, balance, and well-being.
• Inclusive, global, and multicultural engineering culture emphasizing collaboration and respect.
• Opportunities for long-term career growth in technical leadership or system architecture tracks.
