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’re an experienced software engineer who knows what it takes to deliver world-class user interfaces for complex applications. You’ve spent years digging into C++ and can spot an architectural gap or a performance bottleneck before it ever becomes an issue. You thrive on tough technical challenges and know how to turn customer requirements into designs that actually work in the real world—not just on paper. You enjoy mentoring others, but you’re still most at home building, debugging, and shipping code. You’re comfortable leading architecture discussions, reviewing others’ code, and rolling up your sleeves when the team needs support. You know how to balance technical depth and pragmatism, and you care about making things that last. You don’t wait for someone to tell you what’s wrong—you find it, fix it, and help others learn from it. Your communication style is direct, clear, and collaborative, whether you’re talking to a customer, a QA engineer, or a junior developer finding their footing.
