About the Role – Staff Engineer, Cloud Networking & Network Security
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.
You will be responsible for delivering robust networking functionality—from detailed design and implementation through production rollout, scale, and operational maturity.
Key Responsibilities
Networking Design & Implementation
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.
Cloud Networking Platforms
Design and work with cloud networking topologies, including:
VPC/VNet segmentation and routing architectures
Hub-and-spoke and transit networking models
Hybrid and multi-cloud connectivity patterns
Work hands-on with cloud-native networking constructs such as:
Gateways, routing tables, NAT gateways
Managed and custom firewall services
Ensure implementations align with security best practices and zero-trust principles.
Routing, NAT & Traffic Engineering
Design and implement routing-centric features, including:
Dynamic routing using BGP
Policy-based routing and traffic steering
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
Develop a strong understanding of packet-level behavior across gateways, firewalls, and load balancers.
Firewall & Data-Plane Systems
Contribute to the design and implementation of firewall data planes, including:
Policy evaluation and enforcement pipelines
Stateful vs stateless inspection models
Work on performance-sensitive packet processing paths with a focus on correctness and scalability.
Experience working with firewall and network security technologies, such as:
Policy-based rule engines
Stateful and stateless firewalls
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).
Nice to Have
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.
