We Are
Synopsys is the leader in engineering solutions from silicon to systems, enabling customers to rapidly innovate AI-powered products. We deliver industry-leading silicon design, IP, simulation and analysis solutions, and design services. We partner closely with our customers across a wide range of industries to maximize their R&D capability and productivity, powering innovation today that ignites the ingenuity of tomorrow.
You Are
You have spent years turning ASIC designs into working FPGA prototypes, and you know the difference between RTL that compiles and RTL that actually runs reliably across multiple FPGAs at speed. The challenge excites you: partitioning a design that was never meant to be split, closing timing on a path that crosses three SLRs, or debugging a reset issue that only shows up in hardware after two hours of runtime.
You are equally comfortable writing SystemVerilog that synthesizes cleanly and Python scripts that automate the tedious parts of your workflow. When a bring-up fails, you reach for the logic analyzer, the scope, and the source code in that order, and you do not stop until you understand why. You have learned that production-quality tools matter as much as production-quality RTL, and you build both.
Multi-FPGA systems do not intimidate you. Clock domain crossings, inter-FPGA communication, resource utilization analysis, these are problems you have solved before, and you know how to solve them again under new constraints. You work well with hardware teams, software teams, and manufacturing teams because you understand that your prototype is only useful if it helps someone else move forward.
At Synopsys, you will work on HAPS prototyping platforms that enable real customer designs to run before silicon exists. The problems are hard, the systems are real, and what you build will directly affect how quickly our customers can validate their next chip.
What You'll Be Doing
Develop FPGA-optimized implementations for HAPS platforms, addressing capacity limits, timing constraints, and multi-FPGA partitioning challenges
Own the full FPGA development cycle from RTL modification through Vivado synthesis, place-and-route, timing closure, and hardware validation on AMD/Xilinx devices
Drive board and system bring-up for HAPS prototyping hardware, including functional validation, performance characterization, signal integrity testing, and root-cause debug of complex hardware and RTL issues
Develop production-ready test frameworks and automation tools using Python and C/C++ to validate high-speed interfaces, run PRBS testing, analyze eye diagrams, and measure jitter and link margins
Build and maintain multi-FPGA solutions including partitioning strategies, inter-FPGA communication protocols, clock distribution networks, and reset architectures that work reliably across device boundaries
Debug RTL, timing, clocking, and integration issues across simulation, emulation, and physical hardware using lab equipment including oscilloscopes, logic analyzers, protocol analyzers, and spectrum analyzers
Collaborate with architecture, hardware, software, manufacturing, and verification teams to deliver prototyping solutions from concept through production deployment
The Impact You Will Have
Enable customer ASIC designs to run on HAPS platforms months before silicon is available, directly accelerating their validation schedules and reducing risk
Deliver FPGA implementations that close timing, meet performance targets, and run reliably in production test environments, reducing debug cycles and improving product quality
Build automation tools and workflows that make FPGA bring-up faster and more repeatable for the entire HAPS Production Test Team
Solve complex multi-FPGA partitioning and communication challenges that unlock prototyping for designs that would otherwise be too large or too fast for a single device
Identify and resolve signal integrity, timing, and hardware issues that would otherwise delay product releases or cause field failures
Create test frameworks and validation infrastructure that catch issues early and give manufacturing teams confidence in what they are shipping
Contribute technical expertise and design documentation that raises the bar for how the team approaches FPGA development, bring-up, and production test
What You'll Need
Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related field
10+ years of hands-on FPGA and RTL design experience
Expert-level proficiency in SystemVerilog and Verilog for RTL design, with deep understanding of digital design fundamentals, clocking architectures, reset strategies, clock domain crossing, and timing analysis
Extensive experience with AMD/Xilinx FPGA synthesis, place-and-route, and timing closure using Vivado, including optimization for resource utilization, SLR crossings, and routing congestion
Strong programming skills in C/C++ and Python with a proven track record of developing production-quality software, automation frameworks, debug utilities, and engineering tools
Proficiency using lab equipment including oscilloscopes, logic analyzers, protocol analyzers, and multimeters to debug and validate hardware systems
Experience with signal integrity characterization, PRBS testing, eye diagram analysis, jitter measurement, and link margining is a strong plus
Who You Are
When a prototype fails bring-up, you methodically work through the possibilities, RTL bug, clock issue, FPGA tool problem, hardware fault, and you do not assume it is someone else's domain until you have ruled out your own
You write Python scripts and C/C++ tools that other engineers actually use because you care about usability, error handling, and documentation, not just getting something to run once on your machine
You can explain a complex multi-FPGA partitioning tradeoff to a hardware engineer or a software validation lead in terms they understand, without losing the technical nuance that matters
You stay current with FPGA technology, Vivado features, and AMD/Xilinx architecture updates because you know that a new tool capability or device feature can sometimes unlock a solution that was not possible six months ago
You are comfortable working across teams, whether that means reviewing schematics with hardware engineers, debugging test failures with manufacturing, or aligning on requirements with architecture and verification teams
The Team You'll Be Part Of
You will join the HAPS Production Test Team, a group responsible for enabling customer ASIC designs on Synopsys HAPS prototyping platforms and ensuring those systems are validated, tested, and ready for production deployment. Your recruiter will share more about the team structure and mission during the interview process.
At Synopsys, we want talented people of every background to feel valued and supported to do their best work. Synopsys considers all applicants for employment without regard to race, color, religion, national origin, gender, sexual orientation, age, military veteran status, or disability.
In addition to the base salary, this role may be eligible for an annual bonus, equity, and other discretionary bonuses. Synopsys offers comprehensive health, wellness, and financial benefits as part of a competitive total rewards package. The actual compensation offered will be based on a number of job-related factors, including location, skills, experience, and education. Your recruiter can share more specific details on the total rewards package upon request. The base salary range for this role is across the U.S.
