Python Developer – GNSS & Survey Data Processing Automation

Overview

We are a professional land surveying firm seeking a technically strong geospatial engineer to design and implement an automated workflow for processing, organizing, and archiving survey field data.

This role focuses on survey-grade data automation, not web mapping, not cartography.

Our field crews use Topcon data collectors (FC-5000) producing proprietary MJF files, along with static GNSS observations and total station datasets. We want to eliminate repetitive manual handling and build a scalable, automated data pipeline.

What You’ll Build

You will design and implement a Python-based automation system that:

Monitors and backs up raw field data

Parses proprietary MJF survey files

Extracts coordinate and observation data

Separates:

Raw WGS84 coordinates

Localized coordinate systems

State Plane data (when applicable)

Processes static GNSS datasets

Extracts residuals and localization fit metrics

Identifies total station occupation/backsite errors

Preserves control point (GCP) history in WGS84

Automatically unzips, renames, and archives field exports

Generates QA/QC summary reports

Organizes everything into a clean, scalable job directory structure

Optionally builds a structured database (SQLite/PostgreSQL)

This is backend engineering for survey data systems.

Required Skills

Strong Python scripting experience

Experience parsing structured or semi-structured files (binary, CSV, database exports)

Solid understanding of coordinate systems:

WGS84

State Plane

Local coordinate systems

Familiarity with GNSS concepts:

Static observations

Base/Rover workflows

Localization

Residuals

Experience with:

pandas

pyproj

geopandas (preferred)

Experience building automated workflows or ETL pipelines

Strongly Preferred Background

Geodetic Engineering

Land Surveying

Geomatics

Geodesy

GNSS data processing

RINEX file handling

Topcon / Trimble / Leica data formats

Survey QA/QC automation

What This Is Not

This is NOT:

A web map developer role

A cartography or visualization job

A CAD drafting position

A general IT support role

We are looking for someone comfortable with:

Coordinate transformations

Data parsing logic

Survey error analysis

Automation architecture

Clean data structuring

Project Scope

Initial engagement will focus on building the core automation pipeline.

There is strong potential for long-term collaboration and expansion into:

Data architecture refinement

QA reporting tools

Survey data analytics

Internal system integrations

To Apply

Please include:

Examples of automation scripts or data pipelines you have built

Any experience working with survey or GNSS datasets

A short explanation of how you would approach parsing a proprietary survey data format

Your experience with coordinate transformations

Your availability and expected hourly rate

Bonus: If you have worked with Topcon, RINEX, or GNSS static data, please describe your experience.
