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.
This position requires compliance with U.S. government security and/or access requirements. As a result, only U.S. citizens are eligible for this position.
What You'll Be Doing
Making a huge impact by helping the UI team deliver on challenging projects and release requirements
Leading product-level planning, architecture, and research
Coordinating design and development activities with cross-functional teams to deliver robust features and improvements
Serving as a technical reference for the UI development team, mentoring peers and reviewing code for best practices and quality
Developing, maintaining, and enforcing best practices through technical reviews and hands-on mentoring
Tackling complex bug verification and release testing, collaborating closely with QA and product support to resolve challenging issues
The Impact You Will Have
Drive the evolution of STK's UI, making it more intuitive and powerful for thousands of users tackling mission-critical challenges
Shape the technical direction of the UI development team through leadership, mentorship, and technical excellence
Reduce time-to-market for key features by translating customer needs into actionable development plans
Raise the bar for code quality, maintainability, and performance across the product
Strengthen collaboration between engineering, QA, and product teams, ensuring that releases are smooth and issues are caught early
Equip junior developers with the skills and confidence to take on more responsibility through hands-on coaching and code reviews
What You'll Need
BS in Computer Science or related field with 8+ years of experience, or MS with 6+ years
Deep experience in C++ application development, with a track record of delivering robust, efficient code in commercial environments
Strong technical expertise with Visual Studio and experience with large-scale software products
Experience leading projects or technical initiatives in a product development setting
Experience with WPF is a plus
Ability to translate business and customer needs into technical requirements and development plans
Excellent communication and collaboration skills, including mentoring junior developers and working across distributed teams
Who You Are
You break down complex problems and find clear, actionable paths forward-even when requirements are ambiguous or evolving
You're comfortable being the go-to technical reference on your team, and you enjoy helping others level up
You can communicate technical tradeoffs and architectural decisions to both engineers and non-technical stakeholders in plain language
You're proactive about identifying obstacles and finding solutions, not just surfacing issues
You thrive in collaborative environments and believe the best products happen when engineering, QA, and product teams work together
The Team You'll Be Part Of
You'll join the User Interface development team within the Digital Mission Engineering business unit. The team is responsible for the UI of STK, working closely with product management, QA, and customers to deliver features that solve real-world mission modeling and simulation challenges.
