Project Title : Custom 4G/5G & Ethernet WAN Router with Physical Internet Pause Switch Project Overview I am looking for an experienced embedded hardware engineer (or team) to design and build a custom networking device. The device should be capable of receiving internet from either a physical 4G/5G SIM card or an Ethernet WAN input and provide internet through a dedicated Ethernet LAN output. The primary feature is a physical hardware switch that instantly pauses and resumes internet connectivity to the connected LAN device while keeping the Ethernet link active. Functional Requirements 1. Internet Sources The device must support two independent internet sources: A. Cellular Physical Nano SIM card slot. Support 4G LTE and 5G NR. Compatible with as many global 4G and 5G frequency ba...

Advanced OBD-II Vehicle Emulator Development (Freematics MK2 + ESP32) Develop a fully functional advanced OBD-II vehicle emulator based on the Freematics MK2 platform with any additional hardware and custom firmware/software required. The emulator must accurately simulate real vehicles across multiple OBD-II protocols and operate with commercial scan tools as though it were an actual vehicle. Required Features Support CAN, J1850 PWM, J1850 VPW, ISO 9141-2, and ISO 14230 (KWP2000) protocols. Custom firmware for complete protocol simulation and response handling. Vehicle profile library capable of storing multiple vehicle configurations. Import, save, edit, and replay complete vehicle sessions. Accurate VIN simulation (Mode 09). Calibration ID (CAL ID) simulation. Calibration Verifi...

Please refer to the detailed SoW - We need an experienced embedded systems / biomedical hardware consultant to design and develop a compact vitals and body composition acquisition subsystem for integration into an existing diagnostic hardware platform. The system must capture BP, SpO2, PPG-derived respiratory rate, heart rate from PPG/BP, temperature, height, weight, BMI, and body composition values such as body fat %, visceral fat, muscle mass, body water %, bone mass, BMR, metabolic age, and segmental distribution where technically feasible (through bio impedance). The work includes sensor/module selection, hardware architecture, PCB/control board design if required, firmware, Windows/Linux compatible local service/API, local session-wise data handling, calibration workflows, validat...

I’m building a small-scale IoT device dedicated to continuous monitoring and data collection inside a typical home. The core goal is to sense key environmental parameters, push them securely to the cloud, and expose the readings in real time for later analysis. Here’s what I already have in mind: a compact, low-power microcontroller (ESP32 or similar), Wi-Fi connectivity, and a simple set of sensors—temperature, humidity and possibly light or motion—though I’m open to strong technical suggestions. I’ll need you to design the hardware layout, write reliable firmware, and set up the data pipeline (MQTT, REST or another lightweight protocol that fits a home network). Clean, well-documented code with OTA update support is essential. Deliverables • S...

We are seeking experienced Hardware Development Engineers to lead the end-to-end development of a consumer-grade embedded IoT system. This is a collaborative project requiring close coordination between hardware and firmware teams to deliver a production-ready industrial IoT device with advanced wireless capabilities and sensor integration. HARDWARE DEVELOPMENT ENGINEER Key Responsibilities: - System-level hardware architecture and design freeze - Component selection (MCU/SoC, power ICs, storage interfaces, wireless modules) - Schematic design and PCB layout (high-speed + mixed-signal, EMI-aware) - Power integrity, grounding, shielding, and DFM/DFA compliance - Prototype fabrication support and manufacturer Q&A - Hardware bring-up support and validation with firmware engineer - Clear ...
