About the role
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.
Base salary range is $120,000 - $200,000 a year. The base salary offer will depend on factors such as education, experience, training, skills, qualifications, and location. This position is also eligible for a discretionary bonus, equity and a full range of medical and other benefits.
Why Credo
Purpose: We invest in what matters. From meaningful-future shaping projects to competitive compensation, we empower you to grow your career while making a lasting impact.
People: Connection starts within. We collaborate, celebrate wins, and create an environment where everyone can do their best work.
Possibilities: Our belief shapes what’s next. Our technology powers the most reliable and energy-efficient connections around the world – and our team powers new products and markets that come next.
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
Minimum Expertise - expertise in at least ONE of these areas:
High-speed SerDes PHY design, simulation, or validation
DSP / digital communications / communication theory
Wireless communications, analog engineering, or applied physics
Qualifications
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
Preferred Qualifications
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
Who You Are
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;
About Credo
Credo’s mission is to transform connectivity at scale through fast, reliable, and energy-efficient system solutions. Our high-speed copper and optical interconnect products deliver industry-leading power and performance at up to 1.6T to meet the ever-expanding data infrastructure demands of AI.
Our product portfolio includes ZeroFlap (ZF) Active Electrical Cables (AECs) and ZF optical transceivers, OmniConnect memory solutions, and a suite of retimers and DSPs for optical and copper Ethernet and PCIe, all leveraging the PILOT diagnostic and analytics software platform.
