Optical Hardware Engineering Technical Leader, Acacia; Hybrid

Preferred candidates must be able to be onsite in Maynard, MA a minimum of three days per week.

Join our team at Acacia, where we develop advanced optical transceivers for high‑speed fiber optic transmission in data centers and telecommunication networks. We’re seeking enthusiastic, experienced individuals to work on the forefront of fiber optic technology. You’ll be part of the team developing high performance optical transceivers with low power consumption. Collaboration with colleagues from the DSP, SW, HW, PIC teams is key to optimizing performance and power efficiency.

You’ll contribute to producing high volume, high yield products.

• Bring‑up and optimization of each new coherent transceiver design, including optimization of operating conditions of optical and electrical components
• Provide guidance and test results for the development of the integrated optics, high speed electronics, and DSP to maximize performance and minimize size and power consumption of Cisco’s coherent optical transceivers
• Design verification testing (DVT) of coherent transceivers to ensure optical specifications are met over operating conditions (temperature, power levels, etc.)
• Development of calibration and test procedures to ensure consistent high transceiver performance over a wide range of operating conditions (temperature, production variation, ageing, power levels, etc.)
• Work with the operations team to bring these calibration procedures and production tests into high volume manufacturing in a fast, reliable and cost‑effective way
• Work with the operations team to maximize the product yield through good calibration and production test procedures
• Debug of transceivers, both during bring‑up and volume manufacturing

• Bachelor’s Degree with 12+ years of experience or Master’s degree with 8 years of experience, or PhD with 5 years of related experience
• Demonstrated experience with coherent optical communications and DSP optimization
• Demonstrated experience with photonics integrated circuits and their controls for coherent optical transmission

• Experience with test automation, ideally with Python
• Hands‑on experience with high‑speed RF electronics and ADC/DAC
