About this role
1. MAJOR RESPONSIBILITIES:
- Teamwork skills with strong interpersonal communication and responsibility.
- Design and develop accurate signal conditioning chains, signal converters, sampling system, drivers and so on for high precision measurement instruments.
- Architect analog front-end (AFE) solutions for sensor interfacing — covering thermocouples, RTDs, strain gauges, photodiodes, electrochemical cells, and other transducers
- Perform detailed analog signal chain analysis including noise budgeting, bandwidth optimization, dynamic range assessment, and distortion characterization
- Select and evaluate critical components (op-amps, ADCs, DACs, voltage references, analog switches, multiplexers) based on performance, cost, and supply chain considerations
- Design and implement high-resolution ADC and DAC subsystems (SAR, Sigma-Delta, pipelined) with careful attention to grounding, shielding, and clock distribution
- Develop low-noise, low-ripple power supply architectures tailored for sensitive analog circuits with detailed power budget and noise control.
- Conduct SPICE simulation (LTspice, PSpice, or equivalent) for circuit verification, worst-case analysis, and Monte Carlo tolerance evaluation
- Design and debug multi-layer PCB layouts with emphasis on analog-digital partitioning, ground plane integrity, thermal management, and EMC compliance
- Build and characterize prototypes using oscilloscopes, spectrum analyzers, network analyzers, precision multimeters, source-measure units, and thermal chambers
- Perform design-for-manufacturability (DFM) and design-for-test (DFT) reviews to ensure smooth transition from prototype to volume production
- Contribute technical documentation including design specifications, test procedures, validation reports, and application notes
- Participate in cross-functional design reviews and support system-level integration and troubleshooting
- Stay current with emerging semiconductor technologies, converter architectures, and analog design methodologies relevant to instrumentation
2. REQUIREMENTS:
- Bachelor’s or Master’s degree in Electrical Engineering, Electronics Engineering, MS EE or above desired.
- 5+ years of hands-on experience in analog circuit design for measurement, test, or instrumentation applications
- Strong theoretical foundation in analog electronics — feedback theory, stability analysis, noise theory, and linear circuit design
- Proven experience designing circuits with precision op-amps (low offset, low noise, low drift), instrumentation amplifiers, and high-resolution ADCs/DACs (≥16-bit)
- Proficiency in SPICE-based circuit simulation (LTspice, PSpice, TINA-TI, or equivalent)
- Hands-on PCB layout experience using Cadence HDL, Allegro, or similar EDA tools — with demonstrated ability to design 4+ layer mixed-signal boards
- Solid understanding of grounding techniques, shielding practices, and electromagnetic compatibility (EMC/EMI) design principles
- Experience with laboratory instrumentation for circuit characterization — oscilloscopes, spectrum analyzers, precision sources, LCR meters, and thermal test equipment
- Strong problem-solving skills with a methodical approach to debugging and root-cause analysis
- Proficiency in English (written and spoken) for documentation and technical communication
3. EXPERIENCE OF INTEREST:
- Low noise, PPM precision, Op amps, filters, ADC/DAC, amplifiers, loop analysis.
- Experience with FPGA-based digital signal processing for instrument calibration, linearization, or real-time filtering
- Knowledge of embedded C/C++ for microcontroller-based data acquisition and instrument control
- Familiarity with industrial communication protocols (SPI, I²C, RS-485, CAN, Modbus, 4–20 mA)
- Experience designing circuits that comply with IEC 61010, IEC 61326, or similar safety and EMC standards for laboratory/test equipment
- Understanding thermal design principles and temperature compensation techniques for precision analog circuits
- Exposure to data acquisition system (DAQ) architecture design and multi-channel synchronized sampling
- Experience with design for intrinsic safety (IS) or explosion-proof environments is a plus
- Track record of published technical articles, patents, or contributions to open-source hardware projects
