Role description

Description

We are seeking a highly skilled Algorithm Engineer to develop, execute, and automate system-level tests for advanced coherent optical DSP . In this role, you will work at the intersection of signal processing and optical communications to ensure the performance, robustness, and readiness of cutting-edge coherent DSP.

Requirements

Key Responsibilities

  • Design, implement, and maintain system-level test frameworks to validate and stress coherent DSP algorithms across the full signal chain.
  • Develop automated end-to-end test environments including channel models, impairments, hardware-in-the-loop elements, and performance analytics.
  • Create novel stress tests, corner-case scenarios, and fault-injection methodologies to uncover algorithmic weaknesses.
  • Work closely with algorithm developers to define test requirements, acceptance criteria, and performance metrics.
  • Analyze test results, identify root causes of performance degradation, and drive corrective actions.
  • Generate detailed documentation covering test design, simulation assumptions, and system-level performance trends.

Requirements

  • MSc in Electrical Engineering, Computer Engineering, or related field.
  • Experience with MATLAB DSP prototyping and translation C/Phyton.
  • 10+ years of experience in DSP design and modelling , preferably for communications or optical systems.
  • Strong proficiency in MATLAB / C++ , with hands-on experience building modular simulation frameworks.
  • Solid understanding of digital communication systems (modulation, coding, equalization, carrier and timing recovery).
  • Knowledge of coherent optical communications .
  • Excellent problem-solving and teamwork skills.

Nice to Have

  • Familiarity with fixed-point modelling and ASIC/DSP design flow .
  • Exposure to FEC codes (LDPC, RS, OFEC) and their integration into DSP systems.
  • Understanding of jitter, PLL/CDR modelling , and mixed-signal impairments in simulations.

Why Join Us?

  • Be at the forefront of next-gen optical communication systems (800G, 1.6T, and beyond).
  • Collaborate with a multidisciplinary team of DSP, optics, and hardware experts.
  • Influence architecture decisions by providing critical simulation insights.
  • Opportunity for career growth in both DSP algorithm design and system architecture .
