Machine Learning Engineer

We’relooking for aMachine Learning Engineer to join a supportive, multidisciplinary team developing AI/ML systems to solve critical Defence and National Security challenges. In this role,you’lldeveloprobust, production-ready machine learning solutions,exploring, prototyping, and deployingML approaches frominitialconcept through to live operation. Working at the forefront of applied AI alongside experts across multiple disciplines,you’llhelp users defend against Defence and National Security threats, directly contributing to safer, more resilient systems deployed where they matter most.

Mind Foundry works on some of the most complex and urgent challenges in Defence and National Security. We specialise in supporting customers across the community to make sense at the speed of relevance from the ever-increasing volumes of data collected by sensors and systems. We often find ourselves working at the edge in complex environments where power, compute, and bandwidth are in short supply.

The work is challenging, the customer needs products and applications they can trust, and the sense of achievement is thereforesubstantial.

This is an opportunity to innovate at the forefront of applied machine learning, tackle high-impact real-world problems, grow your technical skills, and shape the way AI/ML solutions are delivered to critical operational environments.

Because of the nature of this work:

• You will be required to travel to and work from client sites and partner locations. When not working onsite, this role can be office-based or hybrid from our Summertown, Oxford office.
• You will need toholdexistingorbe eligible for UK Security Vetting (SC), details of which can be found on the Gov UKwebsite.

• Provide advice and explain core ML concepts to our customers and partners.

Core

Skills & Experience:

• A degreein
  
  Computer Science, Applied Mathematics, Statistics, Physics, or a related STEM field (or equivalent practical experience).
• Demonstratedproficiencyin programming languages such as Python, producing clean, reproducible, well-tested, and well-documented code suitable for long-term ownership and handover.
• Hands-on experience with production infrastructure, including Docker, Linux, CI/CD,MLOps, cloud platforms, and model serving architectures.
• Be able to work withstate-of-the-artML libraries to deliver powerful results quickly.
• Comfortable working in ambiguous, fast-moving environments, embedded with customers or delivery teams.
• Hold existingUK security clearance, or willing and eligible to apply and obtain UK security clearance.

Nice to Have:

• Prior experience working with government customers, defence contractors, or in military environments.
• Ability to write technical material (documentation, published papers, internal technical notes etc).
• Experience in areas of model development, dataprocessingand streaming (Spark, Kafka), microservices in python (Flask orFastAPI), and interactive visualisations and User Interfaces (Streamlit,Plotly,Gradioetc).
• Experienceor knowledge ofsignalprocessing,datafusionorAI/ML assurance.

While we think the above experience is important, we’re keen to hear from people that believe they have valuable skills, ideas, or perspectives that will make an impact in this role. If our team and mission resonate with you, but you do not necessarily meet all our requirements, we still encourage you to apply.
