Job description

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 multi-modal wireless mesh sensing technology, driving down the cost and time of deploying sensors by 10ร—. Ultimately, Specter's platform will serve as the perception engine for a company's physical footprint - enabling real-time perimeter visibility and autonomous operations management.
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 Lead RF Engineer to lead the design and development of our modular software-defined radio (SDR) architecture - the communications backbone for our distributed sensing network.
You'll own end-to-end RF system design, from concept and architecture through prototyping, validation, and deployment. This includes architecting a scalable, high-bandwidth, long-range mesh communications layer connecting thousands of edge devices into a cohesive sensing fabric.
As the RF lead, you'll define the company's radio strategy, establish our RF lab and test infrastructure, and grow a small, elite team capable of taking designs from benchtop prototypes to production hardware.
Responsibilities
  • Architect and develop Specter's modular SDR platform, integrating multi-node mesh networking with real-time software control.
  • Define RF system and software requirements across transceiver, front-end, and antenna subsystems.
  • Lead system-level trades to determine optimal network topology, frequency bands, and modulation schemes within software-defined constraints.
  • Design and prototype analog front-end components (LNAs, PAs, filters, matching networks) with tight integration to digital baseband and firmware.
  • Develop automated RF test infrastructure and validation workflows (VNA, spectrum analyzer, OTA testing) with software-driven test harnesses.
  • Collaborate with firmware, networking, and cloud teams to integrate PHY-layer and OpenWRT-based mesh protocols into the broader control plane.
  • Drive DFM, certification, and production-scale RF test automation.
Preferred Background
  • Led RF or communications system development from concept to production, including firmware and software integration.
  • Deep experience with software-defined radios, analog/RF front-end design, and embedded networking systems (<3 GHz).
  • Strong understanding of 802.11 physical layer protocols, OpenWRT, and real-time embedded Linux networking.
  • Skilled with RF simulation and measurement tools (ADS, HFSS, MATLAB, VNA, spectrum analyzer) and software test automation.
  • Experience bringing connected radio products through FCC certification, DVT, and production ramp.
  • Hands-on, experimental mindset - fluent moving between low-level firmware, signal processing, and physical layer hardware.
