Job Overview
We are seeking a skilled Electrical Engineer to join our dynamic team. The ideal candidate will lead the design, development, and implementation of new sensor hardware and embedded firmware for modular weather and air quality monitoring systems.

Duties
• Design, prototype, and test custom sensor circuits and embedded systems for environmental and weather monitoring.
• Develop and optimize firmware for microcontroller-based devices (C/C++), including power-up tests, control logic, and edge algorithm integration.
• Design PCB to deliver robust, scalable sensor
• Collaborate with PCB designers, data scientists, and application engineers to deliver robust, scalable sensor modules.
• Perform verification, debugging, and failure analysis using oscilloscopes, logic analyzers, and other test equipment.
• Develop test firmware, software interfaces, and automated test procedures for sensor validation.
• Integrate analog front ends, wireless communication (Bluetooth Low Energy, cellular- NbIOT, Lte-M, LoRa, etc.), and peripheral components.
• Document theory of operation, requirements, and user manuals; contribute to intellectual property documentation.
• Support process improvement and participate in the transition from prototype to scalable manufacturing.
• Mentor junior engineers and interns as the team grows.

Qualifications
• Bachelor’s degree in Electrical or Computer Engineering or related field (Master’s preferred).
• 5+ years of experience designing and developing embedded systems, preferably for IoT, sensor, or regulated industries.
• Proven experience with embedded firmware development in C/C++ and version control (git).
• Strong background in sensor integration, analog/digital circuit design, and PCB layout.
• Experience with microcontroller platforms (e.g., ARM Cortex, Cypress PSOC, STM32).
• Familiarity with implementing and optimizing edge algorithms on embedded devices.
• Hands-on experience with hardware debugging and test instrumentation.
• Excellent technical documentation and communication skills.
• Excellent problem-solving skills and attention to detail.
• Ability to work collaboratively in a team environment while also being self-motivated.
• Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Preferred Skills
• Experience developing environmental, weather, or air quality sensors.
• Knowledge of wireless protocols (BLE, LoRa, Zigbee) and low-power system design.
• Familiarity with DoD, DHS, or SBIR-funded research projects.
• Exposure to cloud connectivity, IoT platforms, or data analytics integration.
• Experience with rapid prototyping and transitioning designs to manufacturing.

If you are passionate about technology and eager to contribute to cutting-edge projects, we encourage you to apply for this exciting opportunity as a Firmware/Electrical Engineer.
