Post-Silicon Validation Engineer (Multiple Levels) Irvine, CA, or Ottawa, Ontario, Canada
About The Role
Celero is seeking Post-Silicon Validation Engineers to join our validation team for next-generation coherent DSP ASICs powering AI and hyperscale optical networking. As a member of our engineering team, you will play an important role in enabling first silicon, silicon characterization, and ensuring product readiness for customer deployment and high-volume production.
We are seeking multiple levels from early career to Senior Staff level.
This is a role within a fast-paced startup where you will work with Architecture, Design, Firmware, Systems, Apps, Marketing, ATE, Product Engineering, and customers to solve complex silicon challenges. You will have the chance to participate in validation strategy, shape best practices, and be a part of our validation infrastructure from the ground up.
What You'll Do
Post-silicon validation and characterization of complex ASICs and So Cs from first silicon through production release
Participate in functionality, performance, interoperability, compliance, stress testing, corner cases, and reliability functions
Enable first silicon bring-up using JTAG, scan, embedded debug features, and board-level diagnostics
Validate high-speed interfaces including PCIe, Ethernet, Ser Des and other industry-standard protocols
Utilize advanced lab equipment including high-bandwidth oscilloscopes, BERTs, protocol analyzers, Ethernet traffic generators, network analyzers, logic analyzers, and power measurement equipment
Debug complex hardware, firmware, RTL, and system-level issues while working closely with cross-functional engineering teams to identify root causes and drive timely resolution




Contribute to scalable Python-based automation frameworks for test execution, regression, silicon characterization, data analysis, and reporting
Validate firmware, bootloaders, device drivers, and hardware/software interfaces across multiple platforms
Characterize silicon performance, power, thermal behavior, margins, and compliance against architectural specifications
Participate in debug reviews and technical direction for validation methodology, infrastructure, and best practices
Support early customer engagements by reproducing and resolving system-level issues and collaborating with applications engineering
Document validation results, silicon characterization data, debug findings, and production readiness reports
What You'll Bring
Basic Qualifications
Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical discipline, or equivalent experience in lieu of formal education
Hands-on post-silicon validation, DVT, or silicon bring-up experience with complex ASICs or So Cs
Understanding of silicon debug methodologies and structured root-cause analysis
Knowledge of one or more high-speed protocols including PCIe, Ethernet, Ser Des, CXL, USB, SPI, I²C, or similar interfaces
Python programming skills for automation, regression development, and data analysis
Excellent communication skills with the ability to work effectively across cross-functional teams




Comfortable working in a fast-paced startup environment where priorities evolve quickly and every team member has significant technical ownership
Ability to work onsite full-time at our Irvine, California or Ottawa, Canada headquarters. This is not a remote position. We will provide relocation for qualified candidates.
Ability to interpret schematics, understand board design, power sequencing, signal integrity, and hardware debug
Preferred Qualifications
Experience bringing first silicon to production in networking, communications, data center, AI, or high-performance computing products.
Experience using laboratory equipment including oscilloscopes, BERTs, protocol analyzers, network analyzers, logic analyzers, and related validaton tools
Experience validating firmware, embedded software, drivers, and hardware/software interfaces
Experience validating coherent optical DSPs, networking ASICs, Ethernet switch silicon, AI accelerators, GPUs, storage controllers, or high-speed communications devices
Strong knowledge of Ethernet, PCIe, OIF, IEEE, or related compliance specifications
Experience building scalable validation automation, regression systems, dashboards, and data pipelines
Familiarity with customer platform validation and hyperscale qualification processes
Annual Base Salary Range for US: $100,000 - $200,000 (The final offer will be determined based on job-related skills, experience, qualifications, and location.)
