For an exciting well-funded start-up, we are looking for a DSP Optical Communication Algorithm senior engineer.
As an Algorithm Engineer you will be part of the R&D group developing next generation coherent optical transceivers for DCI with data rates of 800Gbps and 1600Gbps. You will design, simulate, and optimize algorithms. You will interact with many different teams such as: Analog, System, VLSI, Design Verification and FW.
What will your work look like?
• Design and simulate DSP architectures, define key capabilities, performance requirements and drive specifications for analog, digital and firmware designers.
• Develop and simulate DSP algorithms and behavioral models of the optical channel, the optical-electrical transceivers and analog units (ADC/DAC).
• Work with designers to ensure circuit architecture can be efficiently implemented.
• Participate in cross-functional teams with analog, digital, and firmware designers for bring-up and validation/optimization activities.
Required Experience
• 5 years or more of hands-on experience and a well proven record of modem algorithms development (Clock Recovery, Equalization, Phase Recovery, and tracking) for Single Carrier modulation and demodulation.
• Fixed point design and programming in MATLAB and C
• Very good understanding of System and HW implementation restrictions (from MATLAB to RTL)
• Lab hands on (algorithms debug and tuning)
Additional Preferred Experience
• Experience with Optical Communication systems
• Understanding analog mixed signal (ADC/DAC/PLL/VCO) and specifications
• Experience with analog circuit calibrations
Educational Background BSc in Electrical Engineering
AI is transforming industries at an unprecedented scale - but today’s data center infrastructure wasn’t built to keep up. As AI workloads grow more complex and data volumes double every two years, connectivity - not compute - has become the bottleneck.
Retym is solving this challenge by delivering next-generation Coherent DSP solutions that provide high-performance, low-latency connectivity for AI infrastructure and data center interconnects.
We are a semiconductor company driven by innovation, bringing together a world-class team of chip designers, optical networking experts, and leading investors to rethink how data moves in the AI era. Our purpose-built DSP technology delivers:
Scalable, high-bandwidth interconnects for AI-driven data centers
Power-efficient, high-performance networking that removes bottlenecks
A coherent DSP provider that gives module makers more control and builds toward a more open, vibrant ecosystem
With hyperscalers deploying AI across multiple locations and AI infrastructure requirements rapidly evolving, Retym is building the connectivity backbone for the future of AI.
The future of AI isn’t just about compute - it’s about how we move data.
Together, we are building a novel semiconductor technology that will transform the datacenter and telecommunications industries.
