The RoleSpecter is hiring an RF Systems Engineer to define and optimize the end-to-end wireless systems connecting thousands of edge devices across large, distributed environments. This role sits at the intersection of RF systems engineering, network architecture, modeling, and fleet-scale deployment.
You will own system-level models, simulations, and architectural decisions that shape how Specter's sensors communicate-balancing long-range performance, power efficiency, resiliency, and cost. You'll partner closely with RF, firmware, and software teams to design, validate, and deploy a robust multi-radio architecture across real-world industrial sites.
This role is deeply cross-functional and highly impactful: your work directly defines the wireless "fabric" that Specter's perception platform operates on.
Responsibilities:- Lead RF and wireless system architecture: modeling, trade studies, and performance validation across Wi-Fi HaLow (802.11ah), 802.11, LTE, 5G NR, and long-range sub-GHz systems
- Root-cause and optimize performance across PHY, MAC, and network 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 into the telemetry pipeline
- Define multi-radio system architectures for long-range backhaul and high-throughput paths across heterogeneous radios
- Build simulation, modeling, and test infrastructure (MATLAB, Simulink, NS-3, automated bench workflows)
- Drive field validation and OTA testing across industrial, logistics, and large-area deployments
- Work cross-functionally with hardware, firmware, and software teams to ensure reliable RF performance in complex environments
- Optimize end-to-end system behavior across routing, addressing, QoS, NAT, DHCP, VLANs, and multi-radio backhaul paths
Qualifications:- Strong background in RF system modeling, link-level simulation, and channel modeling
- Deep expertise in 802.11 PHY/MAC-especially 802.11ah (HaLow)-or similar low-power, long-range RF technologies
- Experience with RF field surveys, propagation analysis, and deployment validation
- Strong experience configuring and debugging RF devices on Linux-based platforms
- Hands-on experience with RF/system modeling tools (MATLAB, Simulink, NS-3) and lab instrumentation (VNA, spectrum analyzer, OTA chambers)
- Experience supporting DVT, FCC/CE certification, production RF tuning, and large-scale operational deployments
