Job description

Develop and maintain PMBI C-based command, control, configuration, and telemetry functionality.
Work with GPIO, ADCs, timers, interrupts, communication peripherals, watchdogs, non-volatile memory and other MCU peripherals as applicable to the hardware.
Analyze firmware interaction with the power-conversion hardware and associated sensors/control interfaces.
Support bring-up, debugging, characterization, and verification of firmware on physical PSC hardware.
Develop automated unit tests, test harnesses, mocks and stubs for firmware modules.
Follow Test-Driven Development (TDD) practices for new functionality and firmware modifications.
Perform regression testing following firmware changes and defect fixes.
Perform static analysis and resolve or disposition findings.
Ensure firmware conforms to JPL C coding standards and MISRA C:2023 requirements, as applicable.
Support hardware-in-the-loop and system-level testing.
Analyze fault conditions and support fault-injection testing where applicable.
Participate in requirements analysis, firmware architecture, design reviews, defect triage, and technical discussions with the customer engineering team.
Contribute to firmware documentation including design descriptions, requirements, interface documentation, test procedures, and verification evidence.
Maintain source code, unit tests, build artifacts, and configuration under Git-based version control.
Support regular firmware builds and milestone releases.
Work closely with hardware, systems, test, and mission-assurance engineers.

Requirements

7+ years of embedded firmware development experience.
3+ years of hands-on bare-metal C development.
Significant experience with bare-metal MCU firmware development.
Experience with power supply, power-management, or power-conversion firmware.
Experience with PMBus and/or SMBus.
Experience developing firmware for mission-critical or safety-critical systems.
Experience with MISRA C and static-analysis tools.
Experience developing automated unit-test frameworks for embedded firmware.
Experience debugging firmware on actual target hardware.
Experience with aerospace, defense, avionics, or space electronics is highly desirable.
Strong proficiency in C programming for embedded systems.
Experience with laboratory power supplies, electronic loads, power analyzers, and other power-electronics characterization equipment is a strong plus.
