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\nYou have spent years writing C++ that actually ships, not prototypes that get rewritten, production code that customers depend on to close timing, route chips, and meet tapeout deadlines. You know the difference between code that works on your machine and code that scales across distributed systems with terabytes of design data, and you have debugged enough memory leaks and race conditions to spot the warning signs three commits before they become production incidents.\nYou do not need a perfect spec to start coding. When requirements are thin, you ask the right questions, sketch out the design with your tech lead, and start building the part you know is solid while the rest gets clarified. You are comfortable working in a large codebase where understanding the existing architecture matters as much as writing new features.\nOptimization is not a nice-to-have for you. You care about runtime, memory footprint, and whether your code will actually perform when a customer throws a 50-million-instance design at it. You write tests because you have seen what happens when you do not. At Synopsys, you will work on PathFinder-SC tools that power physical design workflows used by semiconductor companies worldwide, and the code you write will directly affect how fast and how well those chips get built.\nWhat You'll Be Doing\nDevelop and maintain features for PathFinder-SC products, working in a large C++ codebase with a focus on performance, scalability, and maintainability\nCollaborate with your manager and team to define new functionality, then own and deliver mid-sized projects independently once requirements are clear\nDiagnose and fix bugs across the codebase, including memory issues, performance bottlenecks, and logic errors in complex systems\nOptimize code for runtime speed and memory efficiency, ensuring tools perform well on large-scale semiconductor designs\nWrite unit tests, regression tests, and system-level tests to validate new features and changes before they ship\nCommunicate technical decisions and changes clearly to your manager, tech leads, and other engineers, especially when your work impacts their code\nServe as a technical reference for other engineers on the project team, helping them navigate the codebase and solve design problems\nThe Impact You Will Have\nYour code will power PathFinder-SC tools used by semiconductor companies to route and optimize chips that go into everything from smartphones to data centers\nFeatures you build will directly improve designer productivity, helping customers close timing faster and meet tapeout schedules\nOptimizations you implement will reduce tool runtime and memory usage, enabling designers to work with larger, more complex designs\nTests you write will catch issues before they reach customers, improving product quality and reducing support escalations\nYour technical guidance will help other engineers on the team deliver better code faster\nThe distributed processing improvements you contribute will scale PathFinder-SC tools to handle the next generation of semiconductor designs\nYour work will strengthen Synopsys' position as the leader in physical design automation\nWhat You'll Need\nBachelor's in Electrical Engineering, Computer Science, or related field with 5 years of software development experience, or Master's with 3 years of experience\nStrong C++ programming skills with deep understanding of object-oriented design, STL, memory management, and modern C++ features \nSolid foundation in data structures, algorithms, and debugging techniques, with the ability to diagnose and fix complex issues in production code\nAbility to quickly learn and understand complex systems, and work closely with others to deliver solutions\nTrack record of delivering high-quality work on time in a professional software development environment\nExperience with large-scale commercial software development is a strong plus\nExperience developing physical design or analysis tools for semiconductor workflows is a strong plus\nExperience developing, debugging, or optimizing distributed processing systems is a strong plus\nProficiency in both C++ and Python is a strong plus\nWho You Are\nYou can read someone else's code, understand the intent, and extend it without breaking existing functionality or creating technical debt\nWhen a bug shows up in production, you do not guess, you reproduce it, isolate the root cause, and fix it in a way that prevents similar issues downstream\nYou can explain a technical tradeoff to a senior engineer in a design review and defend your approach with data, not just intuition\nYou know when to optimize and when to ship, and you do not over-engineer solutions for problems that do not exist yet\nYou write code that other engineers can read six months later without needing you to explain it\nYou are comfortable working in a global team across time zones, where clear written communication and well-documented code matter as much as technical skill\nThe Team You'll Be Part Of\nYou will join the PathFinder-SC development team in Chengdu, working on high-performance physical design tools that are part of Synopsys's core EDA portfolio. The team collaborates closely with engineers across global sites to deliver features that directly impact semiconductor design workflows. Your recruiter will share more about the team structure, current projects, and how this role fits into the broader PathFinder-SC roadmap during the interview process.\nRewards and Benefits\nWe offer a comprehensive range of health, wellness, and financial benefits to cater to your needs. Our total rewards include both monetary and non-monetary offerings. Your recruiter will provide more details about the salary range and benefits during the hiring process.\n\nAt 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.","description_format":"text","description_chars":6505,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["EDA Software","Application Security","Semiconductor IP & Chip Design Services"],"lifecycle":[{"event":"open","at":"2026-09-11T01:53:52Z"},{"event":"close","at":"2026-09-14T10:55:12Z"},{"event":"restore","at":"2026-09-14T19:31:41Z"}],"visa":[],"liveness":{"score":17,"band":"cold","label":"Long shot","p_open":1,"p_active":0.611,"p_room":0.28,"age_days":50,"expected_fill_days":16,"reasons":["conf:0","velocity","win:tail","crowd:brand"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/synopsys-rd-engineering-sr-engineer-18623","json_url":"https://alion.io/job/synopsys-rd-engineering-sr-engineer-18623.json","meta":{"generated_at":"2026-11-01T02:53:17Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":4404,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":39954},"rest":"https://alion.io/mcp/rest/get_company?id=39954"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsynopsys-rd-engineering-sr-engineer-18623"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fsynopsys-rd-engineering-sr-engineer-18623"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fsynopsys-rd-engineering-sr-engineer-18623"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/synopsys-rd-engineering-sr-engineer-18623\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsynopsys-rd-engineering-sr-engineer-18623"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":695436}},{"tool":"search_jobs","arguments":{"company":"synopsys.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":695436},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
