Post-Silicon Validation Engineer (Multiple Levels)

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 opportunity 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 SoCs 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, SerDes 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 SoCs
• Understanding of silicon debug methodologies and structured root-cause analysis
• Knowledge of one or more high-speed protocols including PCIe, Ethernet, SerDes, 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.)
