Embedded Systems Firmware Architect

Job Title

Embedded Systems Firmware Architect

Role Summary

Define firmware architecture, control interfaces, telemetry, and diagnostics for digital power management products used in AI, data center, and high-performance computing systems. Partner with firmware teams, hardware design, validation, and systems engineering to produce scalable firmware frameworks and clear firmware-facing contracts.

Experience Level

Senior — 8+ years of experience in embedded firmware, embedded systems, digital power, SoC firmware, control-oriented firmware, or related semiconductor product development.

Responsibilities

Primary responsibilities include architecture definition, interface design, prototyping, and cross-team collaboration.

• Define firmware architecture requirements for digital multiphase power controllers and related products.
• Design system-facing firmware interfaces for telemetry, monitoring, diagnostics, tuning, and control-loop support.
• Translate system requirements into firmware contracts: data structures, APIs, timing expectations, and execution flows.
• Collaborate with systems, firmware, digital and analog design, verification, validation, applications, and tools teams.
• Support embedded characterization methods (signal injection, frequency-response measurement, fixed-point processing, runtime monitoring).
• Provide reference implementations or prototypes to validate architecture and reduce risk.
• Document firmware specifications, interface behavior, operating ranges, timing, and validation expectations.
• Promote reusable firmware patterns across product families while leaving production delivery to implementation teams.

Requirements

Must-have technical skills and experience; preferred items listed separately.

• 8+ years in embedded firmware, embedded systems, digital power, SoC firmware, control-oriented firmware, or related semiconductor product development.
• Strong C programming experience for resource-constrained embedded systems.
• Experience with microcontrollers, embedded peripherals, interrupts, timers, fixed-point math, register interfaces, and hardware bring-up.
• Ability to translate system-level requirements into firmware APIs, data structures, execution flows, and testable contracts.
• Strong written and verbal communication and architecture documentation skills.

Nice-to-have:

• Experience with digital power controllers, DC/DC converters, voltage regulators, or firmware-enabled power management products.
• Experience with frequency-response measurement, Bode-style characterization, embedded auto-tuning, or signal-processing techniques.
• Experience with Python for automation, data analysis, or firmware test infrastructure.
• Familiarity with Verilog/SystemVerilog, hardware modeling, or hardware/software interface definition.
• Experience working across firmware, hardware, validation, software tools, applications, and systems engineering teams.

Education Requirements

Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical discipline.
