• Animation
• Result probing
• Derived calculations
• Min/max extraction
• Result comparison
• Reporting
• Automated post-processing of large-scale engineering simulation data

The successful candidate will act as a senior individual contributor and technical authority, partnering across engineering, architecture, QA, and product teams to deliver accurate, scalable, performant, and maintainable post-processing solutions aligned with customer engineering workflows.

Qualifications

• Bachelor’s or Master’s degree in Computer Science, Mechanical Engineering, Computational Engineering, Computer-Aided Engineering, Applied Mathematics, or a related engineering discipline.
• 12+ years of software engineering experience delivering commercial or enterprise engineering software, preferably in CAE, simulation results, post-processing, visualization, or scientific computing domains.
• Deep expertise in CAE post-processing workflows, including result import, result case management, scalar/vector/tensor handling, contouring, XY plotting, animation, result probing, derived calculations, result comparison, report generation, and solver-specific result interpretation.
• Deep understanding of CAE results data structures, result cases, load steps, time steps, modes, scalar/vector/tensor data, coordinate systems, units, result transformations, and result metadata.
• Hands-on experience implementing workflows for contouring, XY plotting, animations, result probing, min/max extraction, derived result calculations, result comparison, report generation, and automated post-processing.
• Strong background in C++ software development for large-scale engineering, scientific, CAE, graphics, visualization, or data-intensive desktop applications.
• Experience designing and implementing post-processing services, result readers, result databases or data models, plotting frameworks, contouring workflows, animation workflows, report generation pipelines, and production-quality simulation results components.
• Working knowledge of solver output formats, transient and frequency-domain results, scalar/vector/tensor result handling, result transformations, units, coordinate systems, and customer-driven usability requirements.
• Experience with CAE products or simulation platforms such as MSC Apex, Patran, Adams, Nastran, Marc, Abaqus, ANSYS, HyperWorks, ParaView, Tecplot, or equivalent technologies.
• Experience optimizing post-processing operations for performance, memory usage, scalability, responsiveness, and interactive visualization of large simulation result datasets.
• Practical experience using AI-assisted software development tools such as GitHub Copilot, Cursor, or similar tools to improve coding productivity, code review efficiency, documentation, and engineering workflows.

Requirements

• Strong proficiency in C++ for high-performance CAE post-processing, simulation result handling, solver output interpretation, plotting, visualization, or scientific computing applications.
• Required expertise in VTK and related visualization technologies, with practical experience applying rendering pipelines, actors/entities, scene graphs, cameras, picking/selection, overlays, and interaction models to CAE post-processing workflows.
• Strong understanding of 3D graphics fundamentals, including transformations, coordinate systems, mesh topology, level of detail, culling, clipping, transparency, texture mapping, shader concepts, GPU memory usage, and frame-rate optimization.
• Experience diagnosing graphics issues across Windows and Linux environments, including driver/runtime differences, GPU compatibility problems, rendering artifacts, memory leaks, crashes, and performance bottlenecks.
• Hands-on development experience on both Windows and Linux platforms, including platform-specific debugging, build, deployment, graphics/runtime diagnostics, and performance analysis.
• Strong debugging skills using tools such as Visual Studio Debugger, WinDbg, GDB, LLDB, core dump analysis, crash dump analysis, stack traces, logging frameworks, and diagnostic instrumentation.
• Experience with memory, performance, graphics, and concurrency diagnostics using tools such as Valgrind, AddressSanitizer, ThreadSanitizer, UndefinedBehaviorSanitizer, Intel VTune, Windows Performance Analyzer, Linux perf, GPU/graphics profilers, and similar profiling tools.
• Familiarity with automated testing strategies for post-processing workflows using Python, including regression tests, numerical result validation, visualization baselines, solver result comparison, benchmark models, and customer model validation.

Soft Skills

• Strong communication and collaboration skills.
• Problem-solving and analytical thinking.
• Ability to work independently and in a team environment.
• Strong organizational and time-management skills.
