Protocol Reverse Engineer (RF/Wireless)

Orion Edge Group • Town "n" Country, FL

3d • $135,000 - $150,000

About The Position

We are seeking a highly skilled Wireless Reverse Engineer to join our team. In this role, you will analyze, test, and manipulate the radio and physical layers of widespread wireless communication protocols. You will be responsible for understanding complex wireless standards, identifying vulnerabilities, and conceptualizing, designing, and demonstrating disruption strategies (such as jamming, spoofing, and protocol manipulation) against systems utilizing LTE, 5G, Wi-Fi, and Bluetooth.

Requirements

• US Citizenship
• 3+ years of experience in RF engineering, telecommunications security, electronic warfare, or wireless vulnerability research with a bachelors degree (or higher) in a related field.
• In-depth understanding of the OSI model with extreme proficiency in Layer 1 (Physical) and Layer 2 (Data Link) mechanics of cellular (4G/5G), Wi-Fi, and Bluetooth architectures.
• Hands-on experience with Software-Defined Radio hardware (e.g., USRP, HackRF, BladeRF, ADRV9364-Z7020) and software frameworks (e.g., UHD, GNU Radio, srsRAN, OpenAirInterface).
• Strong proficiency in C/C++ and Python for scripting, signal processing, and automating RF attacks.
• Solid foundation in digital signal processing (DSP), modulation schemes (OFDM, QAM, etc.), and error correction methodologies.
• Familiarity with RF lab equipment including spectrum analyzers, oscilloscopes, and signal generators.

Nice To Haves

• Prior experience in the Electronic Warfare (EW) domain.
• Knowledge of IoT protocols (Zigbee, LoRa, Z-Wave) or satellite communications.
• Active security clearance.

Responsibilities

• Protocol Analysis: Deep-dive into the specifications and real-world implementations of wireless protocols (3GPP LTE/5G NR, IEEE 802.11, IEEE 802.15.1, etc.) focusing on the PHY and MAC layers.
• Vulnerability Research: Identify weaknesses in radio frequency implementations, including authentication bypasses, denial-of-service vulnerabilities, and signal degradation thresholds.
• Disruption Strategy Development: Design and execute advanced disruption strategies. This includes developing proof-of-concept techniques for localized jamming, signal spoofing, replay attacks, and man-in-the-middle (MitM) scenarios at the radio layer.
• Software-Defined Radio (SDR) Development: Utilize SDR platforms to build custom transmitters, receivers, and test environments to capture, analyze, and manipulate RF spectrum data in real-time.
• Testbed Engineering: Architect and maintain isolated RF testing environments (e.g., Faraday cages, anechoic chambers, wired RF networks) to safely simulate disruptions without violating FCC/local broadcasting regulations.
• Reporting & Mitigation: Document findings, technical methodologies, and the impact of disruption strategies, working alongside hardware teams to deliver a complete hardware and software product.
