Staff / Senior Staff Analog IC Design Engineer

An innovative technology company operating in the advanced semiconductor industry is developing next-generation CMOS solutions for high-performance and emerging computing applications.

The company is looking for an experienced Staff / Senior Staff Analog IC Design Engineer to join its engineering team. You will be responsible for the design, development, optimisation and validation of advanced analog and mixed-signal integrated circuits, working closely with cross-functional engineering teams to deliver high-performance semiconductor solutions.

Key Responsibilities

• Design and develop high-performance analog and mixed-signal integrated circuits, including amplifiers, data converters and voltage regulators.

• Develop custom analog circuits to meet demanding noise, gain, bandwidth and linearity requirements.

• Perform schematic design and SPICE simulations across Process, Voltage and Temperature (PVT) corners.

• Conduct Monte Carlo and mismatch analysis to ensure circuit robustness and reliability.

• Collaborate with layout engineers on floorplanning, matching, shielding, routing and parasitic optimisation.

• Work with digital design, system architecture and verification teams to integrate analog IP into SoCs.

• Participate in design reviews and contribute to improving design methodologies and workflows.

• Support post-silicon validation, debugging, characterisation and yield optimisation.

• Conduct hands-on laboratory testing using oscilloscopes, spectrum analysers and network analysers.

• Support testing and validation under specialised operating conditions, including cryogenic environments where applicable.

• Research and implement new circuit architectures, technologies and design techniques.

• Maintain technical documentation, including design specifications, simulation reports and validation results.

Requirements

• Master’s or PhD in Electrical Engineering, Microelectronics or a closely related discipline.

• Strong understanding of semiconductor device physics, small-signal models and advanced CMOS technologies.

• Proven analog IC design experience with fundamental circuit blocks such as:

  • Low-Dropout Regulators (LDOs).

  • Operational Amplifiers (Op-Amps).

  • Bandgap References.

  • Phase-Locked Loops (PLLs).

  • Analog-to-Digital and Digital-to-Analog Converters (ADC/DAC).

• Strong understanding of analog and mixed-signal design principles, including mismatch, linearity, stability, low-power and low-noise techniques.

• Hands-on experience developing analog/mixed-signal ICs from design specification through tapeout, silicon validation and production.

• Experience with schematic design, circuit simulation, layout supervision and laboratory characterisation.

• Ability to develop innovative circuit architectures and solutions to meet technical requirements.

• Experience with cryogenic operating environments is advantageous.

• Ability to work independently and collaboratively in a fast-paced engineering environment.
