Junior Robotics Firmware Engineer

Core responsibilities

• Develop bare -metal firmware in C/C++ for real -time, resource -constrained microcontrollers (interrupt -driven, deterministic execution).
  

• Build and maintain low -level drivers and board support for peripherals and protocols: UART, SPI, I²C, PWM, timers, ADC, DMA, and GPIO/EXTI—designed for non -blocking, low -latency operation.
  

• Integrate multi -modal sensing: IMUs, pressure sensors, GNSS receivers, magnetometers, range/altitude sensors, actuator feedback, and custom board peripherals (bring -up through production).
  

• Own system -level debugging across firmware + hardware: root -cause issues spanning power sequencing, brownouts, clocking, reset behaviour, signal integrity, EMI/noise coupling, grounding, sensor bus faults, and component -level failures.
  

• Implement performance and reliability features: watchdog strategy, fault handling, telemetry/diagnostics hooks, timing instrumentation, memory/stack analysis, CPU load measurement, and latency profiling.
  

• Build robust embedded test workflows:
  

  • Unit tests for drivers and logic (with mocks/stubs where needed)
    

  • Bench validation using oscilloscope, logic analyzer, DMM, programmable PSU, signal generator
    

  • HIL/bench rigs to validate firmware behavior under real sensor/actuator conditions
    

• Own the build and release pipeline: Makefiles/CMake, linker scripts, build reproducibility, versioning, and CI -friendly workflows.
  

• Collaborate tightly with electronics/mechanical teams to ensure interfaces, timing, and physical constraints are baked into firmware design from day one.
  

Strongly preferred (nice to have)

• Experience on ARM Cortex -M class MCUs (or similar), including interrupt architecture, NVIC, DMA, and low -power modes.
  

• Real -time design patterns: state machines, ring buffers, lock -free queues, ISR/foreground partitioning, timing budgets.
  

• Familiarity with HALs (and knowing when not to use them), plus clean driver abstractions.
  

• Boot and reliability topics: bootloaders/firmware update flows, reset -safe design, crash logging, error codes, and fault containment.
  

• Exposure to sensor time -alignment, timestamping, calibration handling, and data -quality monitoring.
