Celero Communications Inc. is an exciting and fast-growing start-up in the semiconductor industry, pushing boundaries with innovative technologies that power the world’s most advanced AI and data center infrastructure. We are looking for skilled and motivated DSP design engineers to join our team and help us build optical transceivers for next‑generation optical modems. The ideal candidate must have a robust theoretical background in digital signal processing, digital communications, and fiber‑optic communication systems, with experience developing DSP algorithms for high‑speed communication systems.

Research, develop, and evaluate digital signal processing (DSP) algorithms for high-speed optical communication systems. Design and optimize DSP blocks used in optical transceivers, including adaptive equalization, timing recovery, carrier phase recovery, polarization demultiplexing, and nonlinear compensation. Develop system‑level simulation models of optical communication links and evaluate DSP algorithm performance under realistic channel conditions.

Analyze performance under various impairments such as noise, chromatic dispersion, polarization effects, and hardware non‑idealities. Verify and optimize algorithm performance through floating‑point and fixed‑point simulations. Develop bit‑accurate and cycle‑accurate models to support ASIC implementation.

Document design details and collaborate with ASIC, firmware, and verification teams to ensure reliable implementation in silicon. D. degree in Electrical Engineering, Physics, or Mathematics.



Minimum of two years of industry experience in related fields.

Strong background in digital signal processing and digital communications. Programming experience in C/C++, Python, MATLAB, or similar languages. Familiarity with forward error correction (FEC) schemes used in communication systems.

Experience modeling optical components and electrical frontends of optical transceivers.

Experience with version control systems, specifically GitHub. The chance to play a foundational role at a high-growth semiconductor start-up. Work on cutting‑edge optical communication technologies for AI and data center connectivity.

A collaborative, international team culture where ideas and initiative are valued.
