Join us in our mission to help organisations across Australia get real value from open source GIS! At Mammoth Geospatial, you’ll spend your days on PostGIS databases, QGIS workflows, and field data capture for clients in mining, heritage, and environment, and you’ll teach others how to do the same.

This is a chance to fully embrace open source GIS: connect with the community, become a true expert, and make a difference for the people you work with.

We’re small enough that we can implement new ideas quickly, so you’ll play an active role in how we do things.

About Mammoth

We’re a Fremantle-based team of open source GIS specialists. Through consulting, training, and deploying open geospatial systems, we’ve helped hundreds of people in dozens of organisations, and with the rising tide of open source, there’s more interest than ever in what we do. We need more hands on deck!

The role

We're looking for a Senior Geospatial Consultant who combines strong technical skills with a genuine ability to work with people, solve problems, and share knowledge. We’ve found that consulting and training activities complement each other perfectly, and this role strikes a balance.

Consulting: You’ll work with clients across mining, heritage, environment, and other sectors, helping them set up, use, and get the most from open source enterprise GIS. That means PostGIS databases, QGIS workflows, field data capture, automation, and the day-to-day problem solving and implementation that keeps a GIS running well.

Training: You’ll help develop the Mammoth training program, teaching QGIS, PostGIS, QField, and Mergin Maps to in-house and public groups. You’ll need to be a excellent communicator, explaining things clearly, and knowing how to read the room. You’ll need to know QGIS well enough to teach it, but you’ll also find that every workshop is an opportunity to deepen your knowledge.

Key responsibilities

- Lead client projects from scoping through delivery,



working directly with clients to understand their needs and implement open source enterprise GIS solutions
- Get stuck into hands-on GIS work: cleaning and maintaining data, making maps, deploying field apps, writing metadata, and untangling messy projects
- Design, deploy, and administer PostGIS databases
- Develop and deliver in-house and public training in QGIS, PostGIS, QField and Mergin Maps, and help evolve the training program
- Mentor and support colleagues, sharing skills across the team
- Work constructively as part of a small team

What you bring

The work is varied, so you'll be comfortable switching between projects and clients. We value people who are thoughtful, practical, and dependable, friendly and down to earth. You’ll work well independently. and as part of a team.

Essential

- Proven track record delivering GIS projects independently, in consulting, mining, heritage, environment, or a closely related sector
- Knowledge and practical experience with open source GIS, especially QGIS
- Excellent written and verbal communication, including high-quality documentation
- Experience teaching
- Able to prioritise, plan and manage your own workload
- Strong teamwork skills
- Full working rights in Australia

Desirable
- Experience with PostGIS, QField, and Mergin Maps (we’ll help you fill any gaps)
- Scripting and automation in Python, PowerShell, Bash, and SQL
- Experience developing and delivering technical training courses or lesson plans
- A record of participating in open source communities (tell us how!)
- Experience in cross-cultural, cross-sector, and multidisciplinary work

What we offer

You’ll go deep on open source geospatial technology,



building your skills and knowledge by solving real-world problems and helping real people. You’ll get to work on a variety of projects for different clients, across a range of industries, throughout Australia and beyond. You’ll have some flexibility in where and when you work. Sometimes we work in client offices, and often get together for office days, but working from home is always a big part of the mix. We’re happy to talk about flexible schedules.

In our small, supportive team, you’ll be treated as an individual. We’re interested in your ideas; you’re encouraged and expected to bring new approaches to the work. We aim to foster a respectful team culture where everyone feels valued, included, and supported.

We’ll support your professional development. We work hard to share skills across our team, and we all seek knowledge from outside through self-guided learning, training, and participation in conferences and community events.

We offer a competitive salary of $100,000-$125,000 plus superannuation, depending on your skills and experience, with regular salary reviews.

Working conditions

- Full time (part time open to discussion)
- Initial 12 month contract, with the possibility of extension
- Perth-based, requiring full working rights in Australia
- Hybrid: split between home office, our office and client sites
- Occasional travel within WA and Australia may be required

How to apply

Please send a cover letter and CV to [email protected]. We want to hear about your professional experience, how you’d approach this role, and why you’re interested. Feel free to share examples of your past work. If you’re part of the open source community, we’d love to hear about that too. We appreciate AI can write a cover letter in seconds, but please use your own voice so we can get to know the real you.

Closing date is 27 Nov 2026, though we may close earlier when we find the right person.
