Systems/Algorithms Engineer - Clock and Data Recovery
Location: Athens, Greece
Department: Systems and Software
Cspeed IO is a stealth start up backed by Sutter Hills Ventures and Atreides Capital - headquartered in Palo Alto, CA. Our executive team has a demonstrated track record of building and scaling category-defining semiconductor and infrastructure businesses at companies like Broadcom, Lumentum, Tesla, Apple, Samsung, Intel, and VMware.
Cspeed IO is developing next-generation optical semiconductor solutions for the AI infrastructure market, focused on enabling true “scale-up” architectures. Our mission is to replace traditional copper interconnects with advanced fiber-optic technologies that overcome the limitations of existing optics solutions and architectures.
We are looking for a Systems/Algorithms Engineer in Greece to bridge the gap between high-level design and hardware implementation. Join us in building the next-gen opto-electronic connectivity for AI-driven data centers.
Key Responsibilities
- Architect Clock and Data Recovery (CDR) systems and similar communication links.
- Collaborate closely with RTL and analog circuit designers to define specifications for building blocks.
- Provide system-level tradeoff analysis (power, performance, area, and latency) to guide design choices.
- Model hardware non-idealities, then simulate and validate the system.
- Oversee the implementation to ensure functionality and optimal performance.
- Develop, improve, and maintain bit-true models.
- Document and communicate architectural specifications to cross-functional teams.
Qualifications
- Master’s or PhD in Electrical Engineering, Computer Engineering, or a related field, with at least 5 years of industry experience.
- Strong background in digital communication systems, particularly clock and data recovery and synchronization.
- Experience with bit-true modeling in Python, MATLAB, Simulink, C++, or equivalent environments.
- Solid understanding of high-speed SerDes systems and related algorithms, such as Forward Error Correction (FEC).
- Knowledge of optical fiber communications is a strong plus.
