Senior Firmware Architect – Digital Power & Telemetry

Renesas; Austin (TX); On-site; USD 140,000 - 190,000; Full time

Job summary

Renesas is seeking an experienced Staff Firmware/Middleware Engineer to define firmware architecture for advanced digital power management products used in AI, datacenter, and HPC applications. You will shape system-facing interfaces, telemetry, diagnostics, and control-loop features, partnering with systems, digital, analog, and validation teams.

The role emphasizes prototyping, evaluating tradeoffs, and delivering clear firmware-facing contracts and reusable patterns across product families,

Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or related technical discipline.
• 8+ years of experience 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 skills, including the ability to document architecture clearly for multiple execution teams.

Responsibilities

• Define firmware architecture requirements for digital multiphase power controllers and related power management products.
• Develop system-facing firmware interfaces for telemetry, monitoring, diagnostics, tuning, characterization, and control-loop support.
• Translate system architecture needs into clean firmware contracts, data structures, APIs, timing expectations, and execution flows.
• Collaborate with systems, firmware, digital design, analog design, verification, validation, applications, and software/tool teams.
• Support embedded characterization methods such as signal injection, frequency-response measurement, fixed-point signal processing, runtime monitoring, and health-oriented diagnostics.
• Create reference implementations or early prototypes when needed to reduce architectural risk and validate implementation feasibility.
• Document firmware architecture specifications, interface behavior, operating ranges, limits, timing requirements, and validation expectations.
• Help establish reusable firmware patterns across product families while leaving production firmware delivery ownership with the firmware implementation team.
