We are seeking a highly skilled and visionary Senior Principal Engineer to lead the architecture, design, and development of our next-generation Enterprise Wireless Access Point (AP) solutions. In this role, you will define the software architecture for state-of-the-art Wi-Fi 6, 6E, and Wi-Fi 7 access points.

You will bridge the gap between low-level silicon firmware and high-level cloud management platforms, ensuring our APs deliver enterprise-grade performance, seamless roaming, high security, and cloud-driven scalability. If you have deep expertise in embedded Linux, 802.11 protocols, and cloud-managed networking, we want you on our team.

Technical Leadership & Architecture

• End-to-End Architecture:Own the software architecture, design, and delivery of advanced Wi-Fi features from silicon SDK integration up to cloud-managed provisioning systems.

• Enterprise Wi-Fi Evolution:Design and develop advanced features utilizing Wi-Fi 6, Wi-Fi 6E, and Wi-Fi 7 standards to deliver enterprise-grade performance.

• Advanced Wireless Feature Design:Architect and implement high-value wireless application features including Wi-Fi Mesh, Neighbor Awareness Networking (NAN), Fine Timing Measurement/Locationing (IEEE 802.11mc/az), and advanced enterprise roaming (802.11k/v/r).

• Ecosystem Collaboration:Partner closely with leading Wi-Fi chipset vendors for SDK integration, firmware customization, performance tuning, and hardware platform enablement.

Edge-to-Cloud Integration

• Cloud-Managed Infrastructure:Design, optimize, and deliver cloud-managed and firewall-managed capabilities including Zero-Touch Provisioning (ZTP), remote configuration, real-time monitoring, and centralized control.

• Network & Security Orchestration:Ensure seamless data path orchestration between the AP firmware, local security firewalls, and cloud management dashboards.

Must-Have Technical Expertise

• Wireless Domain Mastery:Strong Wi-Fi Access Point product development experience with a deep understanding of IEEE 802.11 standards (a/b/g/n/ac/ax/be) and wireless security protocols (WPA2/WPA3 Enterprise).

• Advanced Protocol Experience:Hands-on experience developing core firmware/wireless applications for Wi-Fi Mesh, NAN, 802.11mc, 802.11az, and seamless roaming (802.11k, 802.11v, 802.11r).

• Embedded Software Engineering:Expert knowledge of Embedded Linux, Linux kernel internals, device drivers, hostapd, wpa_supplicant, and system-level debugging.

• Language Proficiency:Strong proficiency in C/C++ development for resource-constrained embedded networking platforms.

• Networking Core:Strong networking background including TCP/IP, routing, switching, VLANs, QoS, and enterprise network protocols.

• Network Security:Practical knowledge of network security integrations such as firewall systems, IDS/IPS, threat detection, and policy enforcement at the AP level.

Good-to-Have (Preferred) Qualifications

• Advanced Security & Data Path:Knowledge of Deep Packet Inspection (DPI), malware detection, sandboxing, and Software-Defined Networking (SDN) in large-scale wireless deployments.

• Cloud & DevOps:Direct experience with cloud-managed networking platforms, telemetry/analytics collection, and DevOps/automation frameworks.

• RF Engineering & Optimization:Solid understanding of RF concepts including DFS, dynamic channel planning, interference mitigation, and automated performance optimization.

• Next-Gen Tech: Exposure to AI/ML applications in wireless networking for predictive performance optimization, Wi-Fi analytics, or anomaly detection.

• Experience:Prior technical leadership or architecture ownership experience shipping commercial carrier-grade or enterprise-grade networking products.
