Wireless Architect
Specter is building a software-defined control plane for the physical world. Our mission is to protect and empower American businesses by granting them ubiquitous perception over their physical assets.
We’re creating a connected hardware–software ecosystem built on multimodal wireless mesh sensing, driving down the cost and time of deploying sensors by 10×. Ultimately, Specter’s platform will serve as the perception engine for a company’s physical footprint - enabling real-time perimeter visibility, autonomous operations management, and “digital twinning” of physical processes.
Our founders, Xerxes Libsch and Philip Clark, are building a team of exceptional engineers from Anduril, Tesla, Uber, and the U.S. Special Forces who are redefining how machines sense and understand the physical world.
The Role
Specter is hiring a Wireless Architect to define and optimize the end-to-end wireless architecture connecting thousands of edge devices across large, distributed environments. This role sits at the intersection of RF systems, PHY/MAC design, network modeling, and multi-node mesh communications.
You will own the 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 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 end-to-end RF system architecture: link budgets, channel modeling, coexistence/interference studies, and performance modeling across Wi-Fi HaLow, 802.11, LTE, 5G NR, and long-range sub-GHz systems.
Define PHY ↔ MAC behaviors and system KPIs, guiding how radios schedule, adapt, and operate under constrained real-world environments.
Root-cause and optimize performance across HW, PHY, MAC, driver, and network layers.
Test interoperability with third-party devices and ensure standards compliance across multiple wireless subsystems.
Develop Specter’s RF planning & deployment modeling tools, enabling automated topology planning, coverage prediction, and network-health telemetry.
Collaborate with RF hardware engineers on front-end design (LNAs, PAs, filters, matching networks) and ensure clean integration between analog front-end and digital baseband.
Define multi-radio system architecture for long-range backhaul, local mesh, and high-throughput paths across heterogeneous radios.
Build the simulation, modeling, and testing infrastructure (MATLAB, Simulink, ADS, HFSS, automated bench workflows).
Drive field validation and OTA testing across industrial, logistics, and large-area deployments.
Work cross-functionally with firmware, networking, and ML teams to ensure the wireless stack performs reliably in complex environments.
Support DVT, certification, production tuning, and scaling of radio performance across thousands of deployed systems.
Preferred Background
Experience leading wireless systems architecture from concept → production, covering PHY/MAC, RF, and embedded software integration.
Deep understanding of PHY/MAC internals, scheduling, adaptation, and real-world RF system behavior.
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.
Hands-on experience with RF and system modeling tools (MATLAB, Simulink, ADS, HFSS) and lab instrumentation (VNA, SA, OTA chambers).
Experience supporting DVT, FCC/CE certification, production RF tuning, and large-scale operational deployments.
Comfortable operating across modeling → firmware debugging → RF measurements → field testing.
Bonus (Nice to Have)
DSP or ML-based signal processing experience (algorithm development, PHY prototyping, FPGA/GPU/embedded optimization).
Experience with low-SNR or long-range waveforms, electronic warfare principles, or spectral management.
Background in network telemetry, mesh routing, or real-time network-health analytics.
Hands-on experience with OpenWRT, custom MAC implementations, or driver-level optimization.
