Firmware Engineer II

Description

ABOUT THE ROLE

Spectra Logic is hiring a Firmware Engineer to design, build and validate embedded firmware for its tape library systems, including the Cube and TFinity platforms. You will write the code that runs robotics, motion control, sensors, power and environmental subsystems, and that talks to the LumOS management software.

You will work closely with hardware engineering, QA and software teams. The role spans bring-up of new boards, feature work on shipping products, and root-causing field issues.

RESPONSIBILITIES

- Design, implement and maintain embedded C/C++ firmware for robotics, motor control, sensors, power management and environmental control subsystems.

- Bring up new hardware: board-level debug, peripheral drivers, bootloaders and board support packages.

- Develop and maintain communication interfaces between firmware and the LumOS platform (serial, CAN, I2C, SPI, Ethernet).

- Implement firmware update, diagnostics and telemetry features that support manufacturing, QA and field service.

- Write unit and hardware-in-the-loop tests, and support system-level validation with QA.

- Support compliance testing (EMC, safety, environmental) by building test firmware and resolving issues found.

- Root-cause and fix defects from production lines and customer sites using logs, debuggers, oscilloscopes and logic analyzers.

- Take part in design and code reviews, and write clear technical documentation and release notes.

REQUIRED QUALIFICATIONS

- BS in Electrical Engineering, Computer Engineering, Computer Science or equivalent experience.

- 3+ years developing embedded firmware in C and/or C++ for production hardware.

- Hands-on experience with 32-bit microcontrollers (ARM Cortex-M or similar), on bare metal or an RTOS.

- Working knowledge of common embedded interfaces: UART, SPI, I2C, CAN, GPIO, ADC and PWM.

- Comfortable reading schematics and datasheets, and debugging with JTAG/SWD, oscilloscopes and logic analyzers.

- Experience with Git and a structured code review process.

• Clear written and verbal communication with hardware, software and QA teammates.

PREFERRED QUALIFICATIONS

- Experience with motion control: stepper, BLDC or servo motors, encoders and closed-loop control.

- Background in robotics, data storage hardware or other electromechanical systems.

- Experience with an RTOS such as FreeRTOS, Zephyr or ThreadX.

- Embedded Linux experience (Yocto, device drivers, U-Boot).

- Familiarity with HVAC or thermal control, sensor fusion, or environmental monitoring.

- Exposure to EMC and safety standards (FCC, CISPR, IEC) and how firmware affects compliance results.

- Scripting in Python for test automation and tooling.

• Experience with CI pipelines and hardware-in-the-loop test rigs.

TOOLS AND TECHNOLOGIES

- Languages: C, C++, Python, assembly (reading level)

- Hardware: ARM Cortex-M MCUs, motor drivers, sensors, power controllers

- Interfaces: UART, SPI, I2C, CAN, Ethernet, USB

- Debug and test: JTAG/SWD debuggers, oscilloscopes, logic analyzers, HIL rigs

- Workflow: Git, Jira, CI pipelines, code review
