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.

Requirements

• Typically: Bachelors + 15 years of related experience, or Masters + 12 years of related experience, or PhD + 8 years of related experience.
• 10 years of industry experience in related fields.
• Experience with Digital Signal Processing (DSP) and/or Forward Error Correction (FEC) for coherent optical communications.
• Experience in modeling communication systems.
• Programming experience in C/C++, Python, Matlab, or similar languages.

Nice To Haves

• A master's or Ph.D. degree in mathematics, physics, or electrical engineering is highly recommended, although not strictly required.
• Experience with C++, Linux, and version control systems, specifically SVN and Perforce.
• Experience with Verilog or VHDL, and/or collaboration with ASIC designers.
• Experience presenting technical information to colleagues.

Responsibilities

• Invent, 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.

Benefits

• Quality medical, dental and vision insurance.
• 401(k) plan with a Cisco matching contribution.
• Short and long-term disability coverage.
• Basic life insurance.
• Numerous wellbeing offerings.
• Up to twelve paid holidays per calendar year.
• Flexible Vacation Time Off policy.
