Senior Post-Silicon Validation Engineer (Mixed-Signal SoC)

Location: United States - Remote. The role involves access to ITAR-controlled information and requires either U.S. Person status or eligibility for a federally issued export-control license.

Company

hirify.global develops and mass-produces high-power satellite platforms for commercial and U.S. government missions ranging from low Earth orbit to deep space.

What you will do

• Own post-silicon validation strategy, test planning, execution, coverage, and sign-off.
• Lead first-silicon bring-up across power, clocks, debug interfaces, processor and memory subsystems, peripherals, and high-speed interfaces.
• Define readiness criteria and coordinate silicon, firmware, test infrastructure, and system interfaces for product integration.
• Build the validation lab, including equipment, test setups, infrastructure, and automated characterization and regression environments.
• Characterize RF chains, PLLs, ADCs/DACs, clocking, power, DSP, and calibration algorithms in collaboration with RF/analog, mixed-signal, and systems teams.
• Drive cross-functional debugging and silicon issues from discovery through root cause, workaround, and resolution.

Requirements

• BS/MS in Electrical Engineering, Computer Engineering, or equivalent experience.
• 5+ years of post-silicon validation, SoC bring-up, silicon characterization, or related experience.
• Hands-on experience with complex mixed-signal SoCs/ASICs, lab measurement equipment, validation labs, and automated measurement environments.
• Strong understanding of SoC architecture, RF/analog and mixed-signal circuits, and hardware/software debugging across silicon, RTL, firmware, boards, and systems.
• Strong Python or scripting skills, plus experience with embedded C/C++, JTAG, SPI, UART, and register-level debugging.
• Must be a U.S. Person under ITAR or otherwise eligible for a federally issued export-control license.

Nice to have

• RF SoC and RF/analog characterization experience.
• ADC/DAC, PLL, RF transceiver, or high-speed SerDes/JESD validation experience.
• FPGA prototyping and RISC-V or ARM SoC experience.

Culture & Benefits

• Work on high-power satellite platforms designed for missions from low Earth orbit to deep space.
• Collaborate across FPGA, firmware, RTL/design verification, hardware, RF/analog, DSP, and systems teams.
• Join a high-growth, Series D-funded aerospace company scaling satellite production.
• Reasonable accommodation is available during the employment or interview process.
