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.\nYou Are\nYou have spent years building software that sits between physics and computation, where the code has to be correct, performant, and maintainable all at once. You understand that a well-designed API is what makes a solver actually usable in production, and you have built enough post-processing pipelines to know where they break under real data loads. Writing clean C++ that handles large-scale simulation data is second nature to you, and you know when to reach for Python to prototype or orchestrate workflows without overthinking it.\nYou are comfortable working with scientists and engineers who care deeply about their results, and you translate their needs into software that does not just work today but scales tomorrow. Debugging a data exchange issue or refactoring a module for performance does not intimidate you, it is part of the craft. You care about documentation because you have inherited enough undocumented code to know better. At Synopsys, you will work on multiphysics simulation software that powers real R&D workflows across industries, and the modules you build will shape how engineers interact with complex solvers every day.\nWhat You'll Be Doing\nDesign, develop, and maintain software modules and APIs for multiphysics simulation workflows.\nParticipate in the processing and exchange of large-scale simulation data.\nDevelop post-processing and analysis tools for numerical solver results.\nContribute to software validation, debugging, testing, and product maintenance.\nCollaborate with multidisciplinary teams on the evolution of software components.\nEnsure technical documentation of completed developments.\nThe Impact You Will Have\nEnable engineers and researchers to run multiphysics simulations more efficiently by delivering robust integration and data processing tools\nReduce friction in solver workflows by designing APIs that are intuitive, performant, and well-documented\nAccelerate time to insight by building post-processing tools that handle complex simulation outputs at scale\nImprove software reliability and maintainability across the simulation platform through rigorous testing and clean architecture\nShape the evolution of Synopsys simulation software by contributing to design decisions and technical direction\nSupport cross-disciplinary collaboration by bridging the gap between numerical methods and software engineering\nStrengthen the foundation for future simulation capabilities by building modular, extensible components\nWhat You'll Need\nMaster's degree in engineering, scientific computing, numerical computation, or a related field with at least 5 years of relevant professional experience, or a PhD in a relevant field with at least 3 years of professional experience.\nSignificant experience in scientific or technical software development.\nStrong development skills in C++ and Python.\nExperience in processing and manipulating scientific data.\nExperience in developing post-processing pipelines for numerical solvers.\nStrong analytical skills and a problem-solving orientation.\nUnderstanding of physical simulation concepts (mechanics, fluids, electromagnetism, or related fields).\nExperience with gRPC, MPI, OpenUSD, or GPU programming is a plus\nWho You Are\nPassion for developing robust and high-performance software.\nStrong communication and collaboration skills.\nAbility to learn quickly and work in an international environment.\nYou debug methodically, whether the issue is in your code, a third-party library, or a data format mismatch\nYou are comfortable working across teams and geographies, communicating clearly in English with colleagues who may not share your technical background\nYou know when to optimize for performance and when to optimize for clarity, and you can explain the tradeoff\nThe Team You'll Be Part Of\nThe engineer will collaborate with software development teams and simulation experts to design robust and scalable solutions for scientific computing workflows. Strong expertise in scientific software development, APIs, and solver post-processing is essential.\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.\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":5099,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["EDA Software","Application Security","Semiconductor IP & Chip Design Services"],"lifecycle":[{"event":"open","at":"2026-09-26T16:28:35Z"}],"liveness":{"score":68,"band":"ok","label":"Likely open","p_open":0.9,"p_active":0.835,"p_room":0.9,"age_days":2,"expected_fill_days":7,"reasons":["conf:57","velocity","win:mid","comp:brand"],"computed_at":"2026-09-29T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/synopsys-rd-engineering-sr-engineer-17563","json_url":"https://alion.io/job/synopsys-rd-engineering-sr-engineer-17563.json","meta":{"generated_at":"2026-09-30T01:29:19Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":1048,"day_limit":5000,"remaining_today":3952,"minute_limit":60,"resets_at":"2026-10-01T00:00:00Z"}}}
