About The Position

Team Credo is looking for a Senior Applications Engineer – Digital Signal Processing (DSP) & Communication Systems to join our Optical DSP Application Engineering team. You will play a critical role in release, validation, and system-level reliability of high-speed SerDes DSP products for next-generation AI-driven data centers and hyperscale networks. You will work across the full product stack – from hardware and firmware, to DSP algorithms and automation – while also contributing to a scalable automation and data analysis platform.

Requirements

High-speed SerDes PHY design, simulation, or validation
DSP / digital communications / communication theory
Wireless communications, analog engineering, or applied physics
A master’s degree or higher is preferred in EE, CE, physics, or a related quantitative field, though candidates with a bachelor’s degree and relevant experience are also encouraged to apply. Strong candidates with other degrees will be considered if they demonstrate depth in communication theory, DSP, or related math.
We look for a balance of hands-on experience and solid theoretical fundamentals.
Proficiency in data and signal analysis using Python (NumPy, Pandas, Plotly, etc.)
Strong algorithmic thinking and structured problem-solving ability
Comfortable with Linux, Git, and Docker
Familiarity with control theory and feedback systems
Ability to read schematics and PCB layouts
Self starter and high ownership (“the buck stops with me” attitude)
Bias toward action – you learn by delivering results
Strong communication and collaboration skills
Curiosity and always learning
Thrives in team environments and navigates cross-functional dependencies well
Ready to teach, coach, and mentor others

Nice To Haves

Web app or dashboard development (React, TypeScript, Streamlit)
Experience with MATLAB, SciPy, Octave, or similar tools
Experience with signal integrity and high-speed channel design
Strong “analog sense” or “physics sense” – intuition for how signals behave in real systems
Team management experience is a plus

Responsibilities

Architect, build, and evolve tools for data capture, experiment design, automated testing, and post-processing analysis
Define and execute test plans to improve product reliability and quality
Identify, root-cause, and resolve system-level issues across firmware, analog/digital hardware, and software
Extend data analysis platforms with new DSP/statistical methods, improved pipelines, and software features
Present findings and recommendations to stakeholders and cross-functional teams globally
Coordinate and guide team members while working with Application Engineering, FAE, firmware, and design teams
