Senior C++ Engineer — ParaView & Scientific Visualization
Sign up free to see how well your resume matches this role.
What you'll do
- Develop and maintain ParaView plugins and custom readers in C++.
- Integrate custom data formats and remote data sources into the VTK/ParaView pipeline.
- Translate user interaction into selective data requests by field, timestep, spatial region, and resolution.
- Build progressive loading and rendering workflows for datasets too large to fit fully in memory.
- Implement request cancellation, caching, prefetching, and incremental scene updates.
- Convert streamed data into VTK-compatible structures such as vtkUnstructuredGrid, vtkPolyData, and volumetric datasets.
- Customize ParaView UI and workflows where needed for a better end-user experience.
- Profile and optimize CPU, memory, network, and rendering performance.
- Work with backend and GPU engineers on end-to-end data delivery.
- Contribute selected generic improvements upstream to VTK/ParaView where appropriate.
What they're looking for
- Strong production experience with modern C++.
- Hands-on experience with VTK and/or ParaView.
- Good understanding of the VTK pipeline, readers, filters, data objects, and update requests.
- Experience working with large 3D scientific or engineering datasets.
- Strong understanding of memory management, multithreading, and performance profiling.
- Experience with mesh, volumetric, point-cloud, or time-dependent data.
- Ability to work in a complex mature C++ codebase and debug across multiple abstraction layers.
- Comfortable working close to both product and low-level infrastructure teams.
Nice to have
- Experience writing ParaView server-manager XML, custom panels, or Qt-based ParaView UI extensions.
- Knowledge of remote or distributed ParaView deployments.
- Experience with CFD, FEA, CAE, HPC, or scientific computing.
- Familiarity with Zarr, HDF5, ADIOS2, XDMF, CGNS, Exodus, or similar scientific data formats.
- Experience with spatial indexing, LOD, progressive rendering, or out-of-core visualization.
- CUDA, Vulkan, OpenGL, or GPU-data-pipeline experience.
- Python experience for ParaView scripting and rapid prototyping.
- Open-source contribution experience, particularly in VTK, ParaView, or related projects.

We are toogeza, a Ukrainian recruiting company that is focused on hiring talents and building teams for tech startups worldwide. People make a difference in the big game, we may help to find the right ones.
Currently, we are looking for a Senior C++ Engineer for Zibra AI.
About our client
Zibra AI is a deep-tech company building data infrastructure for spatial and physical AI. With deep expertise in 3D data compression, GPU technologies, and real-time data pipelines, the team develops technology that enables large-scale 3D datasets to be stored, streamed, visualized, and used for AI workflows more efficiently.
Product Overview
Zibra AI is building the data infrastructure layer for Physics AI — bringing streaming, random access, and GPU-native processing to massive 3D scientific datasets. Our goal is to make petabyte-scale simulation data as easy to access and work with as video is today.
