Requirements
- Proficiency in PCB design tools (Altium Designer, KiCad, or equivalent) and EDA simulation tools (LTSpice or equivalent)
- Experience with analog circuit design: transimpedance amplifiers, low-noise signal conditioning, ADC interfaces, and power management
- Experience with embedded microcontroller platforms (AVR, STM32, ARM Cortex, or similar) and firmware development in C/C++
- Knowledge of internal and external digital communication protocols: I2C, SPI, UART, USB, ZigBee, Bluetooth/BLE
- Experience with test equipment: oscilloscopes, logic analyzers, and precision multimeters
- Strong problem-solving skills and attention to detail
- Excellent written and verbal communication skills
- Ability to work independently and collaboratively in a fast-paced startup environment
Nice To Haves
- Familiarity with optical sensing systems, photodiodes, and LED drive circuits is strongly preferred
- Familiarity with regulatory standards (FCC Part 15, CE marking, IEC 61010) preferred
Responsibilities
- Design, develop, and validate analog and digital circuitry for precision absorbance measurement systems, including photodetector amplifiers, LED drive circuits, gas-discharge and arc lamp power supplies, and multi-wavelength optical sensing electronics
- Develop embedded firmware (C/C++) for microcontrollers managing sensor acquisition, data processing, and wireless/USB communication
- Conduct electrical and functional testing, including noise analysis, signal integrity, EMC/EMI evaluation, and regulatory pre-compliance testing
- Collaborate with mechanical and optical engineers to integrate electronics into compact, environmentally robust enclosures suitable for anaerobic chambers, incubators, and field use
- Perform PCB layout, including noise management, impedance control, and thermal management
- Support design for manufacturability (DFM) and design for testability (DFT) activities, working with contract manufacturers and suppliers
- Troubleshoot and debug hardware issues at the board and system level throughout development and production
- Maintain detailed design documentation including schematics, BOMs, design history files, and test protocols
- Assist in the selection and qualification of electrical components and subassemblies
- Support regulatory submissions (FCC, CE, UL) as needed
- Contribute to product roadmap planning and provide engineering input on new product concepts
- Perform ad-hoc engineering tasks as directed by the Chief Executive Officer and/or Engineering leadership
