Stealth-mode startup. Mission-critical tech. Ground-floor opportunity. Our client is an early-stage, stealth-mode company building a new kind of control plane for the physical world, blending hardware, software, and wireless sensing into one unified system. Their work enables Real Time awareness, autonomous operations, and next-gen physical security for high-value assets. They're backed by top investors and led by a founding team with backgrounds from Anduril, Tesla, Uber, and U.S. Special Forces. We're looking for a Wireless Network Engineer to define and optimize the end-to-end wireless network connecting thousands of edge devices across large, distributed environments.

• You will own the system-level models, simulations, and architectural decisions
• Lead wireless network architecture: network modeling, trade studies, and performance validation across Wi-Fi HaLow, 802.11, LTE, 5G NR, and long-range sub-GHz systems.
• Root-cause and optimize performance across PHY, MAC, and IP layers.
• Test interoperability with third-party devices and ensure standards compliance across multiple wireless subsystems.
• Develop automated RF planning and deployment modeling tools, enabling topology optimization, coverage prediction, and pre-deployment performance estimation.
• Collaborate with firmware and software teams to expose critical RF and network-health metrics in the telemetry pipeline, and build monitoring, mitigation, and automation systems to ensure reliable in-field performance.

• Strong background in link-level simulation, channel modeling, and system-level performance analysis.
• Expertise in 802.11 PHY/MAC, particularly 802.11ah (HaLow), or similar low-power long-range technologies and real-world RF system behavior.
• Industry knowledge of RF field survey techniques and tools.
• Strong experience in configuring RF devices on Linux platforms.
• Hands-on experience with RF and system modeling tools (MATLAB, Simulink, NS-3) and lab instrumentation (VNA, SA, OTA chambers).
• Experience supporting DVT, FCC/CE certification, production RF tuning, and large-scale operational deployments.

You'll define the RF backbone of a mission-critical sensing platform. This is a chance to build real, tangible tech with autonomy, speed, and impact from day one.
