About The Position

This is a hands-on technical production position supporting traditional surveying, UAS mapping, LiDAR, photogrammetry, mobile mapping, and terrestrial laser scanning projects. Employees will interact with internal teams, managers, supervisors, external customers, vendors, consultants, and governmental regulatory officials.

Requirements

2+ years of experience in surveying, LiDAR, photogrammetry, mapping, GIS, CAD, or a related geospatial field
Experience working with point clouds or other large geospatial datasets
Experience with topographic or planimetric feature extraction
Understanding of survey control and basic surveying principles
Understanding of coordinate systems, datums, projections, and elevations
Familiarity with breaklines, terrain models, surfaces, and contours
Ability to interpret aerial imagery, LiDAR, survey data, and engineering/construction drawings
Strong attention to detail
Strong computer and technical skills
Ability to recognize questionable or incorrect data instead of simply accepting automated results
Ability to troubleshoot technical problems and develop solutions
Ability to work independently while also collaborating with Project Managers and production teams
Ability to manage multiple projects and changing priorities
Must be authorized to work in the United States
