Embedded Systems Engineer

Salary: $130,000 - 130,000 per year Requirements: We are looking for roughly 7–12 years of experience developing electronic products and embedded systems, or an equivalent track record of comparable strength. We need at least one commercial device taken from concept to a functional prototype, ideally through to production. We expect hands-on experience building both custom hardware and production-ready firmware. We need proven experience directing external partners across PCB, firmware, mechanical, and manufacturing work. You should be comfortable debugging hardware directly with bench tools such as oscilloscopes, logic analyzers, multimeters, JTAG/SWD tools, and rework equipment. Professional PCB design experience is required with tools such as Altium, Cadence, OrCAD, KiCad, or Eagle; Altium is strongly preferred. Strong practical knowledge across embedded hardware, firmware, wireless systems, and shipped connected products is important. Meaningful transferable experience in several relevant areas is expected, including Nordic nRF52/nRF53, STM32, TI low-power and analog components, BLE, battery systems, low-power optimization, sensors, wearable devices, controlled-output devices, secure OTA updates, and high-volume manufacturing. Experience with RTOS platforms such as FreeRTOS or Zephyr is highly valuable. Experience in mobile connectivity, wearable engineering, or regulated/medical-device development is a strong advantage. Responsibilities: We will own the full embedded system from concept through architecture, including microcontroller, radio, sensors, power, outputs, and interfaces with firmware and the mobile app. We will define technical interfaces, evaluate build-versus-buy decisions, and identify engineering, regulatory, and supply-chain risks early. We will design and review analog and digital circuitry for a compact connected device, including power management, BLE performance, charging and protection, user-interface hardware, and fail-safe behavior. We will own schematics and multilayer PCB layouts, with attention to signal integrity, grounding, EMI/EMC, thermal design, and manufacturability. We will drive fabrication, assembly, prototype builds, board bring-up, troubleshooting, and redesign until the hardware is stable and production-ready. We will define firmware architecture, device states, communication protocols, and hardware-control methods, and develop or oversee production-quality C/C++ firmware. We will manage sensor acquisition, BLE pairing and secure updates, output control, battery management, low-power behavior, fault handling, bootloaders, calibration, and diagnostics. We will move devices from proof of concept to engineering prototype and production-equivalent units. We will create test, fault-analysis, and design-verification approaches, while managing BOM cost, component lifecycle, supplier coordination, test fixtures, calibration, and engineering change control. We will use AI extensively to accelerate firmware, research, testing, analysis, and documentation.
