STMicroelectronics Mixed-Signal IC Design Engineer Jobs
STMicroelectronics runs its own fabs in Crolles, Catania, and Agrate Brianza, and that changes what a mixed-signal job looks like day to day. When the process team is down the hall, design-technology co-optimization stops being a slide and becomes a Tuesday meeting. If you have taped out analog on a BCD or FD-SOI node, you will recognize the workflow.
STMicroelectronics mixed-signal IC design engineer jobs cover ADCs, DACs, PLLs, MEMS sensor interface circuits, and power management ICs. The common thread is the boundary between the analog world and digital processing, where layout parasitics and noise coupling decide whether the part meets spec. Most roles expect fluency in SPICE simulation, either Synopsys HSpice or Cadence Spectre, and layout-aware design habits rather than a throw-it-over-the-wall handoff.
ST's product mix is unusually broad, so the segment you land in shapes the work. Automotive teams build SiC power devices and ADAS chips, work that overlaps at the device level with Infineon power IC design jobs. Industrial and IoT teams build STM32 microcontrollers and power management parts. Consumer teams build MEMS sensors and audio ICs. The STM32 family alone has shipped more than two billion units, so a mixed-signal block you design can end up in millions of devices.
Knowing ST's proprietary process technologies helps for experienced hires. BCD handles power management, standard CMOS covers digital-heavy designs, and FD-SOI serves low-power RF and IoT. Real experience with any of the three is a differentiator on the resume.
Design centers sit in Agrate Brianza and Catania in Italy, Crolles, Grenoble, and Sophia Antipolis in France, Shenzhen in China, and Bangalore in India. In the US, ST staffs analog and power IC work in Dallas, Texas and Marlborough, Massachusetts. These roles overlap directly with mixed-signal design engineer jobs across the wider industry, and with ST-specific analog design openings.
For US mixed-signal roles, base pay runs roughly $105K to $140K early-career, $145K to $185K mid-level, and $200K to $270K total compensation at staff, with RF and high-speed data converter specialists near the top of the bands. The salary guide breaks the numbers down by discipline. Save a search on SemiDesignJobs for STMicroelectronics and you will get an email when a role in your segment opens.
FAQ
What process technologies does STMicroelectronics use for mixed-signal IC design
ST uses proprietary BCD (Bipolar-CMOS-DMOS) for power management, standard CMOS for digital-heavy designs, and FD-SOI for low-power RF and IoT. Mixed-signal engineers work across all three families, and picking the node that fits a given block is part of the job.
What mixed-signal products does ST hire IC design engineers for
ADC and DAC designs, MEMS sensor interface circuits, motor control ICs, PMICs, and RF transceiver analog front ends. The range of product lines gives engineers broad design exposure rather than a single narrow specialty.
Does STMicroelectronics offer IC design roles in the United States
Yes. ST runs US design teams in Dallas, Texas and Marlborough, Massachusetts, focused on automotive ICs and power management. SemiDesignJobs lists every US and global ST opening in one searchable place.
