Supporting wider operational initiatives by bringing structure, insight, and clarity to decision-making.
What you’ll bring
Strong Excel analysis and reporting skills, Confident handling large datasets, pivot tables, lookups, and data validation. However, SQL, Python and Reporting (BI) tools are also welcomed for this role.
A naturally curious mindset - someone who enjoys investigating data to uncover what’s really going on.
Experience in fleet, logistics, or transport environments would be a big advantage (understanding downtime, utilisation, and vehicle data). Not a necessity however.
A solid grasp of data quality principles, and how to build trust in reporting.
Clear communication skills, comfortable explaining findings to non-technical teams.
Why join
Work within a national, complex operation where your insights have tangible impact on performance and service delivery.
Join a collaborative and forward-looking team, building structure and consistency in how data is used day-to-day.
Real autonomy freedom to shape reporting, improve processes, and take ownership of your work.

About the Role
You will design, build, and deploy production-grade software, infrastructure, and MLOps systems that leverage machine learning. The work you do will help our customers solve a broad range of high-impact problems in the Defence and National Security arena.
What You’ll Be Doing
You are engineering-focused, with a keen interest and working knowledge of operationalised machine learning. You have a desire to take cutting-edge ML applications into the real world. You will develop new methodologies and champion best practices for managing AI systems deployed at scale, with regard to technical, ethical and practical requirements. You will support both technical, and non-technical stakeholders, to deploy ML to solve real-world problems.
Our Machine Learning Engineers are responsible for the engineering aspects of our customer delivery projects. As a Machine Learning Engineer, you’ll be essential to helping us achieve that goal by:
Building software and infrastructure that leverages Machine Learning;
Creating reusable, scalable tools to enable better delivery of ML systems
Working with our customers to help understand their needs
Working with data scientists and engineers to develop best practices and new technologies; and
Implementing and developing the companies view on what it means to operationalise ML software.
As a rapidly growing organisation, roles are dynamic and subject to change. Your role will evolve alongside business needs, but you can expect your key responsibilities to include:
Working in cross-functional teams of engineers, data scientists, designers and managers to deliver technically sophisticated, high-impact systems.
Working with senior engineers to scope projects and design systems
Providing technical expertise to our customers
Technical Delivery
Who We’re Looking For
You can view our company principles here. We look for individuals who share these principles and our excitement to help our customers reap the rewards of AI responsibly.
To succeed in this role, you’ll need the following - these are illustrative requirements and we don’t expect all applicants to have experience in everything (70% is a rough guide):
Understanding of, and experience with the full machine learning life cycle
Working with Data Scientists to deploy trained machine learning models into production environments
Working with a range of models developed using common frameworks such as Scikit-learn, TensorFlow, or PyTorch
Experience with software engineering best practices and developing applications in Python.

Love finding new ways to solve old problems - when it comes to your work and professional development, you don’t believe in ‘good enough’. You always seek new ways to solve old challenges.
Are pragmatic and outcome-focused - you know how to balance the big picture with the little details and know a great idea is useless if it can’t be executed in the real world.

This role is about end-to-end ownership. From spotting opportunities to deploying models that stick, you ll need to roll up your sleeves, partner with business leaders, and deliver solutions that make a measurable difference.
