🎯 The Role
We are seeking a Staff Engineer – Cloud Networking & Network Security to design, build, and evolve cloud-native networking and security capabilities across multi-cloud environments. This role is intended for a strong hands-on networking engineer with deep experience in routing, NAT, traffic forwarding, and firewall data planes. You will work on complex, production-grade networking systems and contribute to architecture and design decisions within your domain, while partnering closely with senior engineers and architects.
✅ Key Responsibilities
- Design and implement networking components for cloud networking and security products, spanning both control plane and data plane.
- Contribute to architectural designs for routing, NAT, traffic steering, and firewall enforcement within defined product areas.
- Own medium-to-large technical problem areas and drive them from design through production.
- Design and work with cloud networking topologies, including VPC/VNet segmentation and routing architectures, hub-and-spoke and transit networking models, and hybrid and multi-cloud connectivity patterns.
- Work hands-on with cloud-native networking constructs such as gateways, routing tables, NAT gateways, and managed and custom firewall services.
- Design and implement routing-centric features, including dynamic routing using BGP, policy-based routing and traffic steering, and route summarization, convergence, and failure handling.
- Implement and scale NAT functionality, including SNAT, DNAT, and bidirectional NAT, centralized vs distributed NAT designs, capacity planning, port exhaustion handling, and resiliency.
- Contribute to the design and implementation of firewall data planes, including policy evaluation and enforcement pipelines, and stateful vs stateless inspection models.
- Deliver features from design to production with a strong focus on quality, scalability, and operability.
- Participate actively in technical design reviews, providing feedback on networking correctness and performance.
- Collaborate closely with product management, QA, and operations teams to deliver reliable, shippable solutions.
- Mentor junior engineers on networking fundamentals, packet flows, and troubleshooting techniques.
📌 Required Qualifications
- Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, Networking, or a related field.
- 6+ years of experience building networking-intensive systems or cloud networking features.
- Hands-on experience developing or operating cloud networking or network security products.
- Strong understanding of IP networking fundamentals, including TCP/IP, ARP, ICMP, subnetting, CIDR planning, and IP address management.
- Solid experience with routing, including BGP fundamentals (design, policy control, troubleshooting), static vs dynamic routing models, and ECMP and failover concepts.
- Strong hands-on experience with NAT, including SNAT and DNAT behavior, common corner cases and failure scenarios, and interaction of NAT with routing and firewalls.
- Experience working with firewall and network security technologies, such as policy-based rule engines, stateful and stateless firewalls, and NGFW or cloud-native firewall services.
- Proficiency in Python and/or Go (Golang) for building control-plane services, tooling, or automation.
- Good understanding of distributed systems concepts as applied to networking control planes.
- Familiarity with Kubernetes networking concepts, including CNI and service networking.
- Hands-on experience with one or more public cloud networking stacks (AWS, Azure, GCP, OCI).
⭐ Desirable Experience
- Experience with virtual routers, SDN controllers, or network operating systems.
- Exposure to high-performance packet processing technologies (eBPF, DPDK, XDP).
- Experience working on high-scale or latency-sensitive networking systems.
- Contributions to open-source networking or cloud infrastructure projects.
- Certifications such as AWS Advanced Networking, GCP Professional Cloud Network Engineer, CCNP/CCIE, or equivalent.
