Benefits
Full description
What You’ll Do
- Build and enhance networking and security functionality across proxy, DNS, VPN, firewall, routing, and related services.
- Develop C/C++ data-plane components with attention to correctness, throughput, latency, and resource usage.
- Build Go control-plane services, APIs, and tools for configuring and managing multitenant network services.
- Implement configuration changes that can be validated, applied reliably, and diagnosed when something goes wrong.
- Own well-scoped features and defects from investigation and design through implementation, automated testing, and release validation.
- Diagnose production issues using logs, packet captures, debuggers, profiling, and Linux networking tools.
- Develop tests covering protocol behavior, failure conditions, performance, and regressions.
- Work with engineering, operations, and customer-facing teams to deploy and support services across our global network.
Required Skills & Experience
- Typically 4+ years of professional software engineering experience, with demonstrated ownership of production software. Relevant depth and delivery experience matter more than a strict tenure cutoff.
- Experience developing and supporting production Linux systems or networking software, beyond administering Linux servers or deploying applications.
- Strong proficiency in C, C++, Go, or a similar systems-oriented language, with demonstrated experience building and debugging production Linux systems or networking software.
- Strong understanding of TCP/IP, DNS, routing, sockets, and packet flow, including hands-on experience diagnosing networking problems.
- Practical experience with Linux networking behavior and APIs.
- Understanding of concurrency, synchronization, memory and resource management, process behavior, and failure handling.
- Experience investigating performance or reliability problems and using evidence to identify bottlenecks and root causes.
- Ability to independently investigate unfamiliar code and deliver tested, maintainable changes.
- Clear communication of technical decisions, tradeoffs, progress, and risks.
- Level Expectations
- At the Software Engineer II level, you can independently deliver well-scoped work, make sound implementation decisions, and recognize when to seek input.
- At the Senior level, you can also turn ambiguous problems into practical designs, evaluate data-plane and control-plane tradeoffs, lead changes spanning services, and improve engineering quality through technical guidance and design reviews.
- Level will reflect demonstrated scope, judgment, and ownership.
Nice to Have
- Experience developing firewalls, proxies, VPNs, DNS services, IDS/IPS, or other networking and security products.
- Production development experience in both C/C++ and Go.
- Familiarity with BGP, EVPN, VXLAN, and Linux routing.
- Experience with multitenant configuration management and distributed control planes.
- Experience profiling and optimizing network-intensive applications.
- Effective use of AI-assisted development tools, supported by testing and careful review of generated changes.
