Bare-Metal MCU Software Engineer

Project

Work done for a product or program.

• Implement super-loop and interrupt-driven application architectures on Cortex-M, RISC-V, AVR, PIC and C2000 class devices.
• Implement peripheral control for ADC, PWM, timers, comparators, UART, I2C, SPI and CAN without OS abstraction.
• Design state machines for deterministic control loops in motor control, battery management and sensor acquisition.
• Tune duty cycling, sleep-mode entry and wake-source configuration to hit microamp average current targets.
• Measure and minimise flash and RAM usage, including linker script layout, section placement and stack sizing.
• Validate timing with cycle counters, GPIO toggling and oscilloscope capture rather than OS tracing.
• Implement bootloader and in-application programming routines for field firmware update on the MCU.
• Write example projects and application notes that demonstrate silicon features to customers.
• Debug brown-out, watchdog reset, stack overflow and hard-fault conditions from register dumps.

Function

Work that keeps the discipline running: methods, tools, suppliers and people.

• Configure clock trees, PLLs, low-power modes and peripheral muxing directly through vendor HAL or register access.
