Telecommunications Engineering Jobs

I’m building a compact electrolysis hair-removal unit and need a full schematic and PCB layout that an assembler can take straight to production. Core requirements • Control core: ESP32 must set DC voltage (0–24 V), DC current (0–5 mA) and RF power (up to 2 W at 13.56 MHz). Hard cap current limit for DC, the power supply must be unable to supply more for safety. • Dual-path power: DC and RF run independently yet may operate simultaneously. The RF path travels down the probe needle, which is the DC low-side return. A bias-tee approach seems most practical; I’m open to alternative RF/DC combining networks if you can justify them. • High-side connection: the positive DC terminal links to a metal plate the user sits on. If a negative-rail design is e...

I’m experiencing suspicious radio-frequency activity that appears to shadow me from place to place. To put the matter to rest—and, if warranted, take legal action—I need a qualified RF engineer to carry out a comprehensive signal analysis, identify any illicit transmitters, and compile hard evidence. Scope of work • Perform an on-site and near-site sweep that covers my home and the immediate surroundings, with attention to possible satellite-related links. • Use professional-grade spectrum analysers, SDR setups, near-field probes, and direction-finding gear to hunt for audio bugs, covert video cameras, and GPS trackers—each is a genuine concern. • Log every anomaly, capture signal characteristics (frequency, modulation, duty cycle, power level,...

I am ready to launch a new voice service and need a fully verified USA-based SIP trunk that lets me place and receive both domestic and international calls. Monthly traffic will sit in the 1,000 – 10,000-minute range and the trunk must support several concurrent calls without choking, so adequate channel capacity is essential. Here is what I need from you: • Introduce or provision a reputable provider that can activate an account in my company’s name with all necessary KYC completed. • Ensure the trunk is enabled for two-way voice, CLI presentation, 911 compliance, and international reach. • Supply full connection details (SIP URI, username/password or IP auth, codec list) plus concise step-by-step setup instructions for popular soft-switches or an Aster...
