Founding Analog / Mixed-Signal IC Engineer (Semiconductor)

Location: Suffolk County, Massachusetts, United States

Salary: $150,000–$220,000 per year

Company

hirify.global is partnering with an early-stage semiconductor company developing highly integrated 3D hardware platforms that combine advanced silicon, compound-semiconductor technologies, power delivery, and novel packaging for aerospace, communications, high-performance computing, power electronics, and next-generation connectivity.

What you will do

• Architect and design analog and mixed-signal circuitry for control, monitoring, and power-management functions.
• Own IC designs from specifications through schematic design, simulation, layout sign-off, tape-out, and silicon characterization.
• Develop bias generation, sequencing, protection, telemetry, sensing, and power-control circuits.
• Define electrical interfaces between silicon, compound-semiconductor devices, and advanced packaging.
• Characterize returned silicon in the lab and correlate measured performance with simulation.
• Help establish analog design flows, reusable IP, interface standards, and future design methodology.

Requirements

• M.S. with approximately 5+ years of relevant industry experience, Ph.D. with approximately 2+ years, or equivalent hands-on IC design experience.
• Multiple successful analog or mixed-signal IC tape-outs in CMOS, BiCMOS, SOI, or a comparable process.
• Ownership of blocks from architecture and schematic design through physical verification and silicon bring-up.
• Strong experience with Cadence Virtuoso, Spectre, Monte Carlo analysis, PVT/corner simulation, DRC/LVS, and parasitic extraction.
• Hands-on experience in at least two areas: power-management IC design; high-voltage or compound-semiconductor bias/control; phased-array or beamforming control; protection, sequencing, sensing, fault detection, or telemetry; or mixed-signal circuitry for chiplet, multi-die, interposer-based, or 3D-integrated systems.
• Familiarity with high-speed chip and system interfaces such as PCIe, UALink, DDR/LPDDR, UCIe, or related standards.
• Ability to work directly in the lab and debug real hardware.

Culture & Benefits

• Hands-on, end-to-end role with significant architectural ownership.
• Close collaboration across circuits, devices, packaging, RF, thermal, power, and systems engineering.
• Opportunity to influence design methodology, reusable IP, interface standards, and the future analog organization.
