It is a large, production C++ codebase that meshes real industrial geometry with hundreds of millions of degrees of freedom and solves it in parallel.\nYou will join as a R&D engineer working directly with the team of simulation developers. This is a hands-on numerical-methods role: you will own features end to end - formulation on paper, implementation in C++, verification against analytical or reference solutions, and performance work on real customer cases.\n## Responsibilities\n- Derive, implement, and verify finite-element formulations in production C++.\n- Write unit and regression tests, including verification against analytical\nsolutions and benchmark problems; treat a feature as unfinished until it is tested.\n- Profile and optimize solver and meshing code for large models - both runtime and memory.\n- Debug numerical issues on real customer cases: non-convergence, mesh quality, ill-conditioning, and accuracy loss.\n- Write up formulations, assumptions, and validation results clearly enough that a colleague can reproduce them.\n- Work with application engineers, QA, and product management to get features into customers' hands, and respond to what comes back.\n## Required qualifications\n- **PhD in Mechanical / Civil / Aerospace Engineering, Computational Mechanics,\nApplied Mathematics, or a related field** (new graduates welcome), **or an MS in a\nrelated field with 2+ years of relevant industry or research experience.**\n- Solid grounding in **continuum mechanics and the finite element method**: weak\nforms, isoparametric elements, numerical integration, assembly, and the\nNewton-Raphson method for nonlinear problems.\n- Working knowledge of **heat transfer and/or thermomechanical stress analysis** -\nthermal eigenstrain, CTE mismatch, and the behaviour of layered structures.\n- **Strong C++ (C++11 or later)**: you can read and safely extend a large existing\ncodebase, not just write greenfield code. Comfortable with pointers, memory\nownership, templates, and a debugger.\n- Familiarity with **sparse linear algebra** and at least one sparse solver or\nlibrary.\n- Ability to validate your own work: you reach for an analytical solution, a refined\nmesh, or a patch test before you claim something is correct.\n- Clear written and spoken English, and a genuine willingness to work as part of a\nteam - asking for review, giving it, and sharing what you learn.\n## Preferred qualifications\n- Experience with a commercial or open-source FEA code (Abaqus, ANSYS, LS-DYNA,\nCOMSOL, Code_Aster, FEniCS, deal.II, MOOSE) - as a developer, not only a user.\n- Nonlinear FEA: large deformation, contact, plasticity, creep, or viscoplasticity.\n- Parallel programming: OpenMP, MPI, or multithreaded C++.\n- Direct and iterative sparse solvers (MUMPS, PARDISO, SuperLU, hypre/BoomerAMG,\nPETSc) and graph partitioning (METIS/ParMETIS).\n- Mesh generation, mesh quality metrics, or computational geometry.\n- Semiconductor packaging or PCB background: 3D-IC, HBM stacks, solder reliability,\nwarpage.\n- Development on Windows, and on Linux; Git or Perforce.\nWe’re doing work that matters. Help us solve what others can’t.","description_format":"text","description_chars":3476,"description_truncated":false,"requirements":{"experience_years_min":2,"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","Semiconductor IP & Chip Design Services"],"lifecycle":[{"event":"open","at":"2026-10-19T19:31:48Z"}],"visa":[],"liveness":{"score":20,"band":"cold","label":"Long shot","p_open":1,"p_active":0.337,"p_room":0.6,"age_days":44,"expected_fill_days":56,"reasons":["conf:1","stale_co","evergreen","velocity","win:late","crowd:brand"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/cadence-design-systems-lead-software-engineer-13","json_url":"https://alion.io/job/cadence-design-systems-lead-software-engineer-13.json","meta":{"generated_at":"2026-10-21T11:58:19Z","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":16878,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"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":4351},"rest":"https://alion.io/mcp/rest/get_company?id=4351"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fcadence-design-systems-lead-software-engineer-13"},{"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%2Fcadence-design-systems-lead-software-engineer-13"},{"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%2Fcadence-design-systems-lead-software-engineer-13"},{"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/cadence-design-systems-lead-software-engineer-13\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fcadence-design-systems-lead-software-engineer-13"}]}
