Meet the Team

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 DSP for coherent optical transceivers, FEC, and modeling, you help the team to develop the next generation of low-power and high-performance coherent transceivers. Possible topics include:

• Invent, simulate, and validate new DSP or FEC algorithms (floating-point and fixed-point) to improve performance, functionality, or reduce power consumption.
• Test and optimize these algorithms on actual hardware and correlate performance with simulations.
• Develop models of analog RF and optical components and evaluate system performance with these models.
• Analyze the performance of transceiver modules and update models and simulations to match measured results.

Minimum Qualifications:

Typically: Bachelors + 15 years of related experience, or Masters + 12 years, or PhD + 8 years.

• +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.
• A master's or Ph.D. in mathematics, physics, or electrical engineering is highly recommended but not strictly required.

Preferred Qualifications:

• Experience with C++, Linux, and version control systems like SVN and Perforce.
• Experience with Verilog or VHDL, and collaboration with ASIC designers.
• Experience presenting technical information to colleagues.
