Embedded Systems Jobs

I’m building FoodEase, an automatic cooking appliance that runs on a dual-core ESP32. The project is already architected around native ESP-IDF and FreeRTOS, so I need someone who can jump straight into low-level work—no Arduino abstractions—while still writing clean, production-ready code. Here’s what the firmware must do today: handle precise motor control and thermal regulation, collect and analyse data from temperature sensors, and maintain rock-solid Wi-Fi/BLE connectivity with a fully recoverable OTA update path. All of this has to coexist smoothly under FreeRTOS, so tight task scheduling, queues, semaphores and event groups are second nature to you. You’ll be driving PWM channels for the motor, talking to temperature probes over I²C, and keeping...

I want to develop a LabVIEW VI that integrates and synchronizes data from two sources: an Arduino-controlled actuator and a DAQ-based voltage measurement system. The Arduino is responsible for controlling the motion of a stepper motor and continuously outputs position data over serial communication. Specifically, it transmits time and position in a comma-separated format as “time_ms, position_mm” at approximately 50 millisecond intervals. This output has already been verified to function correctly using the Arduino Serial Plotter which I wrote the code for. Also, a DAQ system within LabVIEW is used to measure the analog voltage output from a load cell. This voltage represents the sensor signal and does not need to be converted to force at this stage. The DAQ portion of the sys...

I need complete Gerber files for a multi-layer printed circuit board that will be built on six layers. The schematic is ready; what I’m missing is a clean, production-ready Gerber package that a board house can use without further tweaks. Here’s what I expect: • Layer stack-up defined and documented • Drill files, solder mask, paste mask, silkscreen, and assembly drawings included • All outputs checked against standard DRC rules and CAM verified before hand-off If you normally work in OrCAD, or similar professional tools, that’s perfect—just let me know which platform you prefer so I can provide compatible source files. Turnaround time and any questions about the stack-up or manufacturing constraints are open for discussion; I’m look...

I’m enhancing an Oracle E-Business Suite environment and need a custom OAF page that does three things in a single, streamlined flow. When the user opens the page, a report (already generated as PDF) must appear directly inside the page through an embedded viewer—no pop-ups, no forced downloads. After reviewing the document the user will place a handwritten signature on a Wacom device. I am not tying this to DocuSign, Adobe Sign, or HelloSign; the signature should be captured straight from the Wacom tablet using its SDK or another reliable method your propose, then burned into the PDF. Once signed, the same page should immediately save the updated PDF back into EBS as an attachment (BLOB) so it is viewable from the standard Attachments form. The file format remains PDF from s...

I am building a battery-powered edge node around the STM32WL (LoRa-E5 module) that must sit in the field for years on a single 5 000 mAh cell. To reach that target I need both the hardware design and the accompanying firmware created with an obsessive focus on nano-amp sleep currents and efficient duty-cycling. Core capabilities • Data logging to internal flash or external EEPROM so records are retained between wake-ups. • LoRa communication only; no Bluetooth or Wi-Fi. The node will periodically wake, send an uplink, accept a downlink if present, and return to deep sleep. • Simple sensor block: one digital interrupt input (e.g., reed switch/pulse counter) plus one digital output that can drive an external load for a short, timed burst. Hardware scope – Compl...

I’ve thought of a product that springs to life at the tap of a phone or web button, and I need a talented maker to turn that idea into a fully functioning prototype. The core is a pop-up mechanism—whether you favor solenoids, springs, or a tiny geared motor, I’m open—as long as it rises smoothly, reliably, and safely. Control will come from a Raspberry Pi or Arduino (again, whichever you feel best suits the task), with clean wiring and firmware that listens for a remote trigger. Alongside the hardware, I’ll need a very lightweight app or web page that exposes a simple trigger; bonus points if you can add basic status feedback without over-engineering. I’m happy to supply sketches and dimensions. To keep the conversation focused, please share: • P...
