Embedded Software Jobs

I need a small, purpose-built utility that will unlock a currently blocked feature on my Brovi H155-381 device. You are free to choose the language and framework—Python with pySerial, C/C++, or even a lightweight Java app—as long as the end result is a reliable executable I can run on Windows. If gaining access requires reading or patching firmware, I’ll want clean, well-commented source files and a brief explanation of the offset or command sequence being changed. Deliverables • Compiled utility that unblocks the feature • Full source code and build steps • Short read-me covering usage, prerequisites, and a safe rollback method in case I ever need to restore factory state I’ll supply any device logs you request and can test builds quickly...

I am looking for an experienced ESP32 developer to implement an HTTP server with WebSocket communication and a self-hosted dashboard using ESP‑IDF. Requirements: - Development strictly using ESP‑IDF (no Arduino framework) - Implementation of an HTTP server hosted on the ESP32 - Integration of a WebSocket communication channel for real-time data exchange and commands - Implementation of a simple dashboard (HTML, CSS, JS) for testing WebSocket communication (I will provide almost-ready HTML and CSS files) - Implementation of the JavaScript code for handling WebSocket communication - Hosting the dashboard directly on the ESP32 (embedded in the binary) - Efficient handling of WebSocket messages according to the protocol specification (which I will provide) - Clean, modular, and maintainable c...

I new to design a PCB dedicated to processing several signals and starting a device based on a set number of conditions. I would like to be able to modify those parameters from a cloud based or simple web interface. The board should handles both analog and digital. I expect all to be digital signals but just in case. It should basically handle, temperature, humidity and time of day. Deliverables 1. Compiled firmware binaries plus full, buildable project files 2. Clear inline comments and a concise README explaining build steps and pin mappings 3. A short test report that documents signal-integrity measurements and confirms the module meets the agreed specs. 4, Plus device recommendation and also help on setting up. I have an idea, but I am a genetic engineer. I am OK with basi...

I’m building a mini ventilator—an embedded medical device combining mechanical and electrical subsystems—and I’m looking for a dependable partner who can translate detailed specifications into working hardware and firmware. Your responsibilities will include hardware design, firmware development, and end-to-end integration and testing. How we’ll work: • I’ll provide clear, itemized requirements; you’ll convert them into schematics, PCB layouts, and clean, well-documented firmware. • We’ll maintain a tight feedback loop with regular progress updates, clarification where needed, and rapid iterations after reviews. • Accuracy, reliability, timelines, and strict confidentiality are non-negotiable. Expected deliverables (as appli...
