In this hands-on engineering specialist role, you will
Design, tune, and optimize real-time closed-loop control algorithms (PID, motion control, temperature, and optical power stabilization) operating directly on bare-metal and RTOS microcontroller platforms.
Develop highly efficient, compact embedded C/C++ firmware to configure, monitor, and calibrate hardware subsystems across ARM Cortex-M and Cortex-R cores.
Work closely with Hardware, Optics, and Calibration teams to bring up new boards, characterize feedback loops, and debug electro-optical interactions.
Implement firmware state machines, low-level peripheral drivers, and high-reliability data/control paths.
Own critical firmware features from algorithm simulation to production release, ensuring the highest reliability under demanding and optical conditions.
Minimum Qualifications (Objective Requirements)
Bachelor’s degree in Electrical, Electronics, or Computer Engineering or related field with 8+ years of professional experience.
6+ years in low-level embedded C and C++ programming for physical hardware control.
5+ years development of embedded firmware on bare-metal systems and real-time operating systems (RTOS such as VxWorks, FreeRTOS, ThreadX, or similar).
Design, implementation and tuning real-time control systems (e.g., closed-loop feedback, PID control algorithms, or motion/thermal control loops) on embedded microcontrollers (such as ARM Cortex-M or Cortex-R).
Ability to work 100% onsite during the initial one-year onboarding period, (with hybrid flexibility available thereafter).
Preferred Qualifications
Development of control firmware for optical transceivers, laser controllers, optical amplifiers, or telecommunications hardware.
Expertise with schematic reading, board bring-up, and lab instrumentation (oscilloscopes, logic analyzers, optical spectrum analyzers).
Development of multithreaded control-plane firmware, interrupt handlers, and complex finite state machines.
Proficiency with version control (Git, Jira, Perforce) and test automation/data analysis scripting (Python, MATLAB).
Background in semiconductor devices, hardware startups, sensor integration, or automated test platforms.

Exempt employees participate in Cisco’s flexible vacation time off program, which has no defined limit on how much vacation time eligible employees may use (subject to availability and some business limitations)
80 hours of sick time off provided on hire date and each January 1st thereafter, and up to 80 hours of unused sick time carried forward from one calendar year to the next
Additional paid time away may be requested to deal with critical or emergency issues for family members
Optional 10 paid days per full calendar year to volunteer
For non-sales roles, employees are also eligible to earn annual bonuses subject to Cisco’s policies.
Employees on sales plans earn performance-based incentive pay on top of their base salary, which is split between quota and non-quota components, subject to the applicable Cisco plan. For quota-based incentive pay, Cisco typically pays as follows:
.75% of incentive target for each 1% of revenue attainment up to 50% of quota;
1.5% of incentive target for each 1% of attainment between 50% and 75%;
1% of incentive target for each 1% of attainment between 75% and 100%; and
Once performance exceeds 100% attainment, incentive rates are at or above 1% for each 1% of attainment with no cap on incentive compensation.
For non-quota-based sales performance elements such as strategic sales objectives, Cisco may pay 0% up to 125% of target. Cisco sales plans do not have a minimum threshold of performance for sales incentive compensation to be paid.
