About Quantum Solutions

Our company is a leading innovator in the field of advanced materials and imaging technologies, specialising in quantum dot semiconductors, SWIR imaging systems, drone payloads, and end to end inspection services used across solar panels inspection, precision agriculture, environmental monitoring, and smart infrastructure. Our commitment to cutting-edge research and development allows us to deliver solutions that meet the evolving needs of our customers.


Position summary

We are seeking a photogrammetry specialist to assist us with the Q.Fly® drone imaging platform post processing flow end to end: ingesting flight logs and GNSS events; running PPK/RTK and validating absolute accuracy against GCPs; performing SfM/MVS with rigorous camera calibration, seamline optimization, and radiometric balancing; and delivering orthomosaics, DSM/DTM, and point clouds with clear QA (RMSE, reprojection error, GSD). You should be fluent in Pix4D/Metashape (or similar), RTKLIB and QGIS/ArcGIS, comfortable scripting Python/Bash to automate pipelines at scale, and able to publish COG/WMTS/XYZ tiles or web map visualizations for stakeholders. Knowledge of mission planning and multispectral/SWIR workflows is a plus.


What you’ll bring

* GNSS/IMU mastery: PPK/RTK processing (e.g., RINEX, event markers), camera GNSS time sync, antenna offsets, and accuracy validation against GCPs/CPs; strong grasp of CRS/geoids and datum/projection transforms.
* Q.Fly workflow fluency: Parsing Q.Fly flight logs, aligning trigger events to imagery, troubleshooting missed/duplicate triggers, and verifying metadata integrity (EXIF, timestamps).
* Photogrammetric processing: Feature matching, bundle adjustment, camera/lens calibration (IO/EO, distortion models), dense reconstruction (SfM/MVS), and robust seamline optimization/deghosting.
* Image stitching & mosaicking: Building high‑quality orthomosaics/GeoTIFFs with consistent radiometry and color balance; producing DSM/DTM/point clouds (LAS/LAZ) and documenting RMSE/reprojection error/GSD.
* Software toolchain: Proficiency with Pix4D/Metashape/RealityCapture or OpenDroneMap; GNSS tools (e.g., RTKLIB); GIS (QGIS/ArcGIS Pro); point‑cloud QA (CloudCompare).
* Visualization & delivery: Creating orthomosaic visualizations as COGs/WMTS/XYZ tile pyramids; publishing to QGIS/ArcGIS dashboards or web maps (Leaflet/Mapbox) and lightweight 3D viewers where useful.
* Automation & scale: Scripting (Python/Bash) to batch pipelines, CLI operation of photogrammetry tools, GPU/compute management, containerization (Docker), and data versioning.
* Data stewardship & QA: Large‑dataset organization, checksum/metadata hygiene, acceptance criteria, accuracy reports, and reproducible SOP documentation.
* Field‑aware judgment (nice‑to‑have): Mission planning insights (overlap/sidelap, GSD targets, shutter speed/exposure), radiometric targets, and sensor quirks; multispectral/SWIR handling is a plus.
* Collaboration: Clear written reporting, issue tracking, and cross‑team coordination with flight ops and GIS consumers.



At Quantum Solutions, we offer a dynamic, research-driven work environment with opportunities for professional growth and the chance to work with cutting-edge imaging technologies. We value diverse perspectives and believe great ideas come from different experiences and backgrounds; we welcome everyone—regardless of gender, ethnicity, age, disability, or any other aspect of identity.

If you need adjustments during the recruitment process, let us know.
