- Collaborate closely with architecture and QA teams to define and deliver robust software components.
- Debug and resolve complex issues across multiple layers (application, transport, and network).
- Analyze crash files and debug with the team to resolve them
- Configure and troubleshoot virtual networking in virtual machine (VM) environments - bridges, TAP/TUN interfaces, VLANs, and virtual switches (like OVS).
- Deploy and test networking software inside VMs or virtualized test environments (e.g., KVM, VMware, VirtualBox, or cloud VMs).
- Collaborate with DevOps and QA teams to ensure seamless deployment, configuration, and testing workflows.
- Participate in design and code reviews, enforcing best practices for maintainable, high-quality code.
- Mentor junior engineers and contribute to technical design discussions and documentation.
