Technical Leader DSP Engineer – Coherent Optical Transmission Systems - Acacia (Hybrid)

Cisco•Maynard, MA

3d•Hybrid

About The Position

Join our team at Acacia, where we design 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 Digital Signal Processing (DSP) and Forward Error Correction (FEC) algorithms for our optical transceivers' Application-Specific Integrated Circuits (ASICs). Collaboration with colleagues from the DSP and ASIC teams is key to optimizing performance and power efficiency. You'll contribute to system design, develop architectures, and support ASIC design and verification. Work closely with colleagues across various fields and gain diverse knowledge in optical system testing, analog components, modeling, and more. Your Impact With your expertise in communication systems, you help the team to develop the next generation of low-power and high-performance coherent transceivers. Here are some examples of possible topics: Design, simulate and validate new DSP or FEC algorithms (both in floating-point and fixed-point precision) to improve performance and functionality or lower power consumption Test and optimize these algorithms on actual hardware and correlate performance with previous simulations Develop models of analog RF and optical components and evaluate system performance with these models Analyze performance of developed transceiver modules and update models and simulation environments to accurately match the measured results Work closely with the optical testing and firmware teams to develop robust algorithms for calibration and run-time optimization of the transceivers

Requirements

Bachelors + 12 years of related experience, or Masters + 8 years of related experience, or PhD + 5 years of related experience, or equivalent related work experience.
Experience in modeling communication systems or simulating digital signal processing algorithms.
Programming experience in C/C++, Python, Matlab, or similar languages.

Nice To Haves

A master's or PhD degree in mathematics, physics, electrical engineering or related fields.
Experience with Digital Signal Processing (DSP) and/or Forward Error Correction (FEC) for optical communications.
Experience with C++, Linux, and version control systems, specifically SVN and Perforce.
Experience working in a lab for optical communications.
Experience with coherent and direct-detect optical communication systems
Experience presenting technical information to colleagues.
