Geodesist
Location (Including Home Working Ratio): Sunbury, UK 50%
Duration: 6 months +


Role Summary:
  • The Geodesist will provide expert geodesy services and maintain the organization's geospatial data's accuracy, consistency, and reliability.
  • This includes managing the client’s geodetic system of record (CRS Catalogue), deriving and implementing new coordinate reference systems and transformations, and ensuring geodetic integrity across various spatial datasets, applications, and systems.
  • The role involves collaborating with internal teams, external partners, and regulatory bodies, developing geodetic APIs, contributing to source code, and performing quality control on geospatial and geoscience data.
  • The Geodesist also supports data science and management workflows, delivers training on geodetic principles, and plays a key role in decision-making on geodetic issues within the geoscience portfolio.
  • A strong focus is placed on driving innovation, automating workflows, and continuously improving organizational geodetic practices and standards.
  • Support core business activities in the Geodetic team for Upstream (Exploration, Development, Production).
  • The Geodesist should be proficient in more than one technology/application providing spatial analysis capabilities.
  • Candidates should have deep knowledge of at least one core Geodetic discipline and be able to design, produce, and execute deliverables aligned with that discipline.
  • The candidate will continue to grow technical skills and gain experience by working as part of a broader team, project, or initiative under the direction and guidance of SMEs.

Responsibilities:
  • Apply knowledge of geodetic mathematics to accurately measure the Earth's geometry, orientation in space, and gravitational field as a framework for treating spatial data.
  • Possess working knowledge of satellite geodesy and the ITRF and World/National datum relationship.
  • Basic understanding of Static and Dynamic datums and their relationship with the ITRF datums.
  • Develop and implement data mappings ranging from single systems to complex multi-systems and identify/promote data standards that facilitate the interaction of spatial data between systems.
  • Knowledge of platform and database technology required to design, implement, and support spatial data repositories and software tools.
  • Experience in the QC workflow to improve spatial data quality in one or more data repositories.
  • Possess general knowledge of programming languages and algorithms such as C++, Python, MATLAB, and the use of APIs.
  • Demonstrate working knowledge of positioning systems (calibration, validation, and operation), apply measurements in a 3D reference frame, and establish the location of offset points.
  • Has working knowledge of physical oceanography related to subsea positioning (CTD profiles, tides, sound velocity & propagation).
  • Understand various survey techniques to provide geodetic control (e.g., Satellite/Theodolite/Levelling traverses, Reference station baselines, etc.), including least squares network adjustments, residual / RMS accuracies, and orthometric height determination.
  • Understand the difference between National/Regional map projections and WGS84 UTM grid projections. Able to verify the datum transformation and map projection settings in a Vessel Navigation System against project requirements.
  • Experience in QC and resolving survey issues with geophysical/geotechnical surveys, rig positioning and subsea construction activities (e.g., topographic, levelling, utility, and nearshore interface surveys, USBL and LBL acoustic systems), able to verify the datum transformation and map projection settings in a Vessel Navigation System against project requirements, ensuring grid convergence is applied appropriately.

Requirements:
  • Relevant Tertiary degree and practical experience in Geomatics roles with exposure to Geospatial Science or related Geoscience disciplines.
  • Deep industry knowledge within at least one core Geodetic discipline; able to design, produce, and execute deliverables aligned to that discipline.
  • Proficient in more than one technology/application providing spatial analysis capabilities.
  • Perform routine geospatial analysis, computations, and adjustments.
  • Capable of working independently on various survey and geodesy-related tasks with minimal supervision.
  • Proficient in independent quality control checks on vendor reports and data deliverables.
  • Candidates should have over 3 years of professional experience in one or more areas pertinent to Geodetics.
  • Demonstrated leadership, adaptability, teamwork, excellent communication skills in English, and a commitment to higher safety and ethical standards. In addition, candidates should be able to work effectively within and across diverse technical teams.
